Overview • 11OverviewCPC’s Radio Frequency (RF) Sensor System provides refrigerated case temperature monitor-ing and control without the time and expense required to wire multiple temperature sensors from the cases back to the area controllers. All sensors in the RF Sensor System family are completely wireless, transmitting their values to receivers in the store area that pass them back to the area controllers.Figure 1-1 - RF System Diagram
2 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-001.1. Hardware Components1.1.1. Sensors1.1.1.1. RF Ambient Temperature Sen-sorsThe RF Ambient Temperature Sensor is an enclosure with a built-in broadcast antenna. This sensor may be mounted anywhere within a refrigerated case, as long as it is within 150 feet of an RF Receiver and within a clear line of sight to the receiver’s antenna.Four models of the RF Ambient Temperature Sensor are available. Each model has either internal or external temperature sensing ele-ments, and either clean switch or defrost termi-nation digital inputs. Table 1-1 lists all RF Ambient Temperature Sensor models along with their characteristics.Figure 1-2 - Ambient Temperature Sensor (Internal Model Shown)Part Number Description809-3542 RF Internal Ambient Sensor, w/ sensor element mounted inside enclosure, and with a built-in clean switch button for alarm suspension during cleaning809-3544 RF External Ambient Sensor, w/ external NSF-approved stainless steel bullet sensor and neoprene leads, with external leads for con-nection to clean switch809-3552 RF Internal Ambient Sensor, w/ sensor element mounted inside enclosure and external leads for connection to digital defrost termi-nation sensor809-3550 RF External Ambient Sensor, w/ external NSF-approved stainless steel bullet sensor and neoprene leads, with external leads for con-nection to digital defrost termina-tion sensorTable 1-1 - RF Ambient Sensor Models
Hardware Components Overview • 31.1.1.2. RF Long-Range Ambient Sen-sorsThe RF Long-Range Ambient Sensor improves on the 150 feet transmitter-to-receiver maximum distance of the other internal & exter-nal sensor models. The cylindrical enclosure holds a “whip” antenna capable of transmitting to receivers as far away as 200 feet.Like the shorter-range sensors described in Section 1.2.1.1., there are both internal and external models of the long-range sensors, both with either clean switch or digital defrost termi-nation inputs. Table 1-2 lists each long-range sensor model.1.1.1.3. RF Product SimulatorThe RF Product Simulator (P/N 809-3548) mimics the thermal characteristics of product within refrigerated cases or freezers. Tempera-ture readings from product simulators can be used to verify product remains within acceptable food safety levels.Figure 1-3 - Long-Range Ambient Sensor EnclosurePart Number Description809-3543 Long-Range Internal Ambient Sensor, w/ internal temperature sensor element and clean switch button809-3545 Long-Range External Ambient Sensor, w/ NSF approved stainless steel bullet sensor and neoprene leads, with external leads for clean switch809-3549 Long-Range External Ambient Sensor, w/ NSF approved stain-less steel bullet sensor and neo-prene leads, with external leads for digital defrost termination sensor809-3551 Long-Range Internal Ambient Sensor, w/ internal sensor element and external leads for digital defrost termination sensorTable 1-2 - Long-Range RF Ambient Sensor ModelsFigure 1-4 - RF Product Simulator
4 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-00The sensing element and transmitting antenna for the RF Product Sensor are inside the enclosure and may transmit to receivers up to 150 feet away. The sensor also has an internal clean switch, which is activated by pressing a button on the enclosure.1.1.2. RF ReceiverThe RF Receiver (P/N 837-3510) is an antenna that mounts to the ceiling of the sales area or on top of a refrigerated case. The RF Receiver accepts transmissions from RF Ambi-ent Temperature Sensors and RF Product Simu-lators. It passes the sensor readings it receives to the RF Gateway by way of an RS485 network connection. Up to six RF Receivers may be mounted within a single building. 1.1.3. RF GatewayThe RF Gateway (P/N 810-3500) is an RS485 peripheral board compatible with both Einstein and REFLECS (RMCC, BEC, and BCU) systems. The RF Gateway serves as an interface between the RF Receivers, which send messages from the sensors, and the area control-lers, which use the sensor values for logging, controlling, and alarming. Each Einstein or REFLECS controller that will read values from RF Sensors must be equipped with an RF Gate-way.Sensors and product simulators that will be used by an Einstein must be “commissioned” in the RF Gateway’s software. Once a sensor is commissioned, the gateway then assigns the sen-sor to a virtual "board and point" address. This allows the area controller to tie application inputs to RF Sensor values in the same way tra-ditional 16AI board and point inputs are set up.Figure 1-5 - RF ReceiverFigure 1-6 - RF Gateway Board
Hardware Components Overview • 51.1.4. Hand-Held TerminalThe Hand-Held Terminal (HHT) (P/N 811-3110), shown in Figure 1-7, connects directly to the RJ11 jack on an RF Gateway and is used to commission RF Sensors and view the status of the system. Figure 1-7 - Hand-Held Terminal (HHT)
6 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-002 Installing the RF Gate-wayInstalling the RF Gateway device for a site controller involves mounting and powering the device, connecting to the CPC controller’s RS485 network, and networking the RF Gate-way with other gateways and receivers on-site. 2.1. Mounting the RF Gate-wayThe RF Gateway is typically mounted in the same area as the site controller, near the control-ler’s 16AI, 8RO, and other RS485 network peripherals. The RF Gateway is designed to fit into a standard 3" snap track (supplied with the board). The RF Gateway should be mounted in an environment with ambient temperature between -40°F and 150°F, with a non-condensing relative humidity between 5% and 95%.2.2. Powering the RF Gate-wayThe RF Gateway requires 24VAC power from a Class 2 center-tapped transformer. CPC supplies several sizes of center-tapped trans-formers for powering multiple 16AIs, 8ROs, and other RS485 peripheral boards of the Einstein and REFLECS systems. Refer to your controller’s user manual for information on how to use the center-tapped transformers listed in Table 2-1 to power multi-ple RS485 I/O devices. The RF Gateway requires 4VA of power to operate.Figure 2-1 shows how to connect the 56VA and 100VA transformers to the RF Gateway power connector. Figure 2-2 shows how to con-nect the 175VA transformer to the RF Gateway.Three-Board Six-Board Ten-BoardP/N 640-0043 640-0045 640-0048Power Rating 56 VA 100 VA 175 VATable 2-1-Power Ratings for CPC TransformersFigure 2-1 - Pinout for the 56VA (640-0043) and 100VA (640-0045) Transformers26513001208 VAC110 VAC11224455FOR 208 VAC POWER SOURCEFOR 110 VAC POWER SOURCE10108866AC1AC10V0VAC2AC2PINOUT10 8 612 45
Wiring the RF Gateway to a CPC Site Controller (I/O Network) Installing the RF Gateway • 7 2.3. Wiring the RF Gateway to a CPC Site Controller (I/O Network)Each Einstein or REFLECS site controller that will receive a temperature value from an RF Sensor must have an RF Gateway installed on its RS485 I/O Network. For Einstein controllers, this means the RF Gateway will be installed on the I/O Network; for RMCC, BEC, BCU, and other REFLECS products, the RF Gateway will be installed on the COM A or COM D network.2.3.1. Wire ConnectionUsing shielded three-conductor network cable (Belden #8641 or equivalent), connect the RS485 I/O Network wire to the three-terminal connector on the RF Gateway board as shown in Figure 2-3. For further information about how RS485 networks are configured, refer to your site controller’s user manual.2.3.2. Setting the Board Number-ing Dip SwitchThe Einstein or REFLECS controller inter-prets the RF Gateway board as a series of four 16AI Analog Input boards numbered in succes-sion. Dip switches 1 through 4 set the first board number used by the RF Gateway; when this number is set, the RF Gateway will also use the next three board numbers above the first board number. For example, if an RF Gateway dip switch is set to board number 3, the RF Gateway will use board numbers 3, 4, 5, and 6 on the I/O Network.Figure 2-2 - Pinout for the 175VA (640-0048) TransformerFigure 2-3 - Connecting the RF Gateway to the RS485 NetworkNote: The RF Gateway dip switch is mounted upside down on the circuit board. Figure 2-4 and Figure 2-5 show the correct positions of the dip switches when viewed upside down.
8 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-002.3.3. Setting the Baud Rate Dip SwitchDip switches 6 and 7 control the baud rate at which the RF Gateway communicates with the site controller on the RS485 Network. These switches must be set to the same baud rate set-ting as the Einstein or REFLECS (usually 9600 baud).Dip switch 8 controls the baud rate at which the RF Gateway communicates with the other devices on the Token Ring Network. This baud rate may only be set to either 9600 baud (switch DOWN) or 19600 baud (switch UP). All RF Gateways and RF Receivers on the Token Ring Network must have the same baud rate dip switch setting. It is recommended you use 9600 baud as the Token Ring Network baud rate.2.3.4. Setting the RS485 I/O Termi-nation JumpersAs part of an area controller’s RS485 I/O (COM A or COM D) Network, an RF Gateway must be terminated if it is the end device of a daisy chain. Refer to the controller’s user man-ual for information about daisy chain networks and how they are terminated.To terminate the RF Gateway, set the I/O Network Jumpers to the LEFT position as shown in Figure 2-6. To unterminate the RF Gateway, set the jumpers to the RIGHT position.Figure 2-4 - Dip Switch Setting for Numbering RF GatewayFigure 2-5 - Dip Switch Setting for Numbering RF GatewayFigure 2-6 - RF Gateway RS485 I/O Network Termination
Networking Gateways and Receivers (Token Ring Network) Installing the RF Gateway • 92.4. Networking Gateways and Receivers (Token Ring Network)The RS485 Token Ring Network intercon-nects all RF Gateways and Receivers on the site. Like the RS485 I/O Networks that interconnect the area controllers, input boards, output boards, and RF Gateways, the Token Ring Network must be set up in a daisy chain configuration. All devices must be wired together in a single chain as shown in Figure 2-7, with no branches and with no device connected to more than two other devices.2.4.1. Wiring the Token Ring Net-work to the GatewayUsing shielded three-conductor cable (Belden #8641 or equivalent), wire the RF Gate-way to the Token Ring Network as shown in Figure 2-8.2.4.2. Setting the Token Ring Net-work Termination JumpersAs shown in Figure 2-7, the Token Ring daisy chain must be terminated at the two devices at the end of the chain. The location of the termination jumpers on the RF Gateway are shown in Figure 2-9. To terminate an RF Gate-way, set the jumpers to the LEFT position. To unterminate the RF Gateway, set the jumpers to the RIGHT position.Figure 2-7 - Daisy Chain Configuration - Token Ring NetworkFigure 2-8 - Token Ring Network WiringFigure 2-9 - RS485 Token Ring Network Termination
10 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-003 Installing the RF Re-ceiverInstalling an RF Receiver requires mounting the receiver, powering the receiver, and network-ing the receiver together with other receivers and gateways on the RS485 Token Ring Network.3.1. Mounting and Placement of the RF Receiver3.1.1. Environmental Operating ConditionsThe RF Receiver should be mounted in an environment with ambient temperature between 30°F and 120°F, with a non-condensing relative humidity between 5% and 95%.3.1.2. PlacementThe RF Receiver must be placed above the sales floor within 150 feet of the sensors it will receive transmissions from. Each RF Sensor in the store must be no more than 150 feet from an RF Receiver, so for installations that require multiple receivers, make sure each RF Receiver is placed so that all RF Sensors have a receiver within the maximum distance.3.1.3. MountingThe receiver may be mounted either against the ceiling (with the antenna pointing toward the floor) or on top of a case (with the antenna point-ing directly toward the ceiling). Alternately, the receiver may be mounted sideways (e.g. on a riser or a wall), but this will limit the range of reception to only those RF Sensors that are within the 180° arc of the direction the antenna is pointing (i.e. it may not pick up sensors located behind the receiver base). Note the status LEDs and wire connections are located on the bottom of the receiver enclo-sure; try to mount the receiver so that these con-nections are accessible.3.2. Powering the RF Receiv-erThe RF Receiver requires a 9VDC power source. A 110VAC to 9VDC transformer is sup-plied with the RF Receiver. Plug the adapter into the receiver base, and connect the transformer to a 110VAC line.3.3. Wiring the RF Receiver to a CPC Site ControllerEach RF Receiver passes along sensor val-ues it receives to an RF Gateway on its RS485 Token Ring Network.
Wiring the RF Receiver to a CPC Site Controller Installing the RF Receiver • 113.3.1. Wire ConnectionConnect the Token Ring Network wire to the three-terminal connector on the RF Receiver board as shown in Figure 3-1.3.3.2. Setting the Token Ring Net-work Termination JumpersThe devices at each end of the Token Ring Network daisy chain must be terminated. To ter-minate the Token Ring Network at the RF Receiver, set the jumpers to the UP position, as shown in Figure 3-2. To unterminate the RF Gateway, set the jumpers to the DOWN position.3.3.3. Setting the Receiver Num-bering Dip SwitchThe RF Receiver must be identified with a unique number on the RF Gateway network. This allows RF Gateways to determine the source of incoming temperature readings. RF Receivers must be numbered sequentially, start-ing with #1 and continuing to the maximum number of receivers allowed (currently 6). Figure 3-1 - Connecting the RF Receiver to the RS485 NetworkFigure 3-2 - RF Receiver Token Ring Termination Settings
12 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-00To assign an RF Receiver a number on the RF Gateway network, set switches 1-5 to the desired number. See Figure 3-3.3.3.4. Setting the Baud Rate Dip SwitchDip switches 6 and 7 control the baud rate at which the RF Receiver communicates with the site controller on the Token Ring Network. These switches should be set to the same posi-tion as all other Token Ring Network devices so they will communicate at the same baud rate. It is recommended the baud rate be set at 9600 baud for all Token Ring devices.Figure 3-3 - Dip Switch Setting for Numbering RF ReceiverFigure 3-4 - Dip Switch Setting for RF Receiver Baud Rate
Placement of RF Sensors Installing the RF Sensor • 134 Installing the RF Sen-sorThis section details how to install the various models of RF Sensors, including mounting and placement, activation, and clean switch and defrost termination wiring.4.1. Placement of RF SensorsIdeally, all RF Sensor models, including product simulators, should be located some-where within a refrigerated case where a clear line of sight exists between itself and an RF Receiver. In any case, the signal path between the RF Sensor and the RF Receiver should not be blocked by large amounts of product or thick metal case walls. 4.1.1. RF (Short-Range) Ambient SensorThe RF Ambient Sensor kit includes a plas-tic mounting clip. This clip may be fastened any-where on a shelf or the side of a refrigerated case. After mounting the clip, the sensor may be snapped on to the mounting clip.4.1.2. RF Long-Range TransmitterThe RF Long-Range Sensor transmitter enclosure is equipped with two endcaps, each of which has a mounting hole. Screw the sensor enclosure to a shelf or the side of a case using the endcap mounting holes.4.1.3. RF Product SimulatorThe RF Product Simulator kit includes a plastic mounting clip. This clip may be fastened anywhere on a shelf or the side of a refrigerated case. After mounting the clip, the sensor may be snapped on to the mounting clip.4.2. ActivationAll RF Sensors will be shipped with the power OFF (a.k.a. Sleep mode) to save battery life. The sensors must be activated before they will start transmitting. To activate the sensor, locate the Service button and press for one sec-ond (see Figure 4-1 for the service pin loca-tions). When activated, the sensor LED will stay ON for one second to indicate the sensor is exit-ing Sleep mode and beginning operation.4.2.1. Verifying Active StateWhen an RF Sensor is active, you can verify its active state by momentarily pressing the Ser-vice button and then releasing. If active, the sta-tus LED will flash once. If the light does not come on, it is either in Sleep mode or has a dead or missing battery.4.3. Clean Switch and Defrost Termination WiringSensor models with internal clean switches do not require any extra wiring to enable clean switch functionality; the button on the sensor enclosure acts as a clean switch.Figure 4-1 - RF Sensor Activation
14 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-00Sensor models with connections for external clean switches and digital defrost termination sensors are equipped with a two-wire pigtail. Connect the clean switch or defrost termination contacts to these leads.WARNING! External clean switch and defrost ter-mination inputs are to be connected to dry contacts only. Do not connect the leads to any voltage or current source. Doing so will damage the sensor and void the warranty.
What is Commissioning? Commissioning the RF Sensors • 155 Commissioning the RF Sensors5.1. What is Commissioning?Commissioning is the act of linking an RF Sensor’s input to a virtual "board and point" address in a specific RF Gateway’s memory so it can be read and used by a CPC area controller. The act of commissioning involves assigning each virtual board and point in an RF Gateway’s software with either the temperature value or the digital input value from a specific RF Sensor. This is achieved by:• Specifying the unique ID number of the RF Sensor that will supply the value to the cho-sen board and point address, and • Specifying whether the board and point address will output the sensor’s temperature value or the digital input value (from either the clean switch or the defrost termination sensor).A sensor can be commissioned either by manually entering sensor ID numbers into the RF Gateway software or by pressing a sensor’s service pin to broadcast the ID number to the RF Gateway via an operational RF Receiver.5.2. Manual Entry MethodEach RF Sensor and product simulator has a sticker on the enclosure that displays an ID num-ber unique to the sensor. This sticker also has a perforated tag that may be removed from the enclosure.When using the Manual Entry method of commissioning sensors, it is recommended you remove each perforated ID tag after installation and attach it to a data sheet along with informa-tion about its location and the name of the Ein-stein or REFLECS controller that will read the sensor’s value. Appendix A provides a template that may be photocopied for creating RF Sensor data sheets.When you’ve collected all the ID numbers from the RF Sensors and product simulators for your site, the ID numbers may be entered on the RF Gateways to commission the sensors. Figure 5-1 - The Process of Commissioning
16 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-005.2.1. Entering the ID Numbers on the RF GatewayThe RF Gateway board is designed to simu-late four 16AI Analog Input boards, each of which has sixteen inputs, for a total of 64 inputs per gateway. To commission a sensor, you must use the Hand-Held Terminal to associate the sen-sor ID number with a "board and point" input address on the gateway.1. Plug the Hand-Held Terminal into the HHT jack on the RF Gateway. The HHT should power up and display the opening screen.2. Press the DOWN ARROW key to display the Options menu.3. Press the RIGHT ARROW, 1, DOWN ARROW, and DOWN ARROW to select the "Set Sensor ID" option and navigate to the ID Entry Method screen.4. In the ID Entry Method screen, press RIGHT ARROW, 1, DOWN ARROW, and DOWN ARROW to select the "Enter ID #" method and navigate to the Enter Start-ing Board Address menu.5. The Enter Starting Board Address menu allows you to jump to Point 1 of the number of the "board" you wish to configure. The four board numbers reserved by this gateway are shown in parenthesis on line 3 of the screen. To begin commissioning sensors on a "board," press RIGHT ARROW, the num-ber of the board you wish to configure, DOWN ARROW, and DOWN ARROW.6. The commissioning screen for Point 1 of the board number you chose will be visible on the screen. There are two configurable parameters on this screen: TYPE, and ID. Press the RIGHT ARROW key to move the cursor to the TYPE field.7. If you want this board and point input to be the temperature read by the RF Sensor, press 1 to change the TYPE field to "TEMP." If you want this board and point input to be the state of the RF Sensor’s digital output (whether it be its clean switch or defrost ter-mination sensor input), press 2 to change the TYPE field to "DIGITAL." When selected, press the DOWN ARROW key to confirm.8. The cursor should now be on the ID field. In the ID field, enter the number from the ID tag or sticker on the RF Sensor enclosure. When finished, press the DOWN ARROW key to confirm and save.9. Press the DOWN ARROW key again to move on to the next point on the board. Fol-low steps 6 through 8 again to commission the next board point. If you wish to switch to a different board, pressing F2 will move you
Service Pin Method Commissioning the RF Sensors • 17back to the Enter Starting Board screen described in step 4.5.3. Service Pin MethodAll RF Sensor models have a service pin that, when pressed, will transmit its ID number. The service pin can be used to commission the sensor by commanding the RF Gateway to receive the transmitted ID number and assign it to a "board and point" input address.This process will likely require two people: one to set the RF Gateway up to receive the sen-sor ID transmissions, and one on the sales floor to press the service pins.5.3.1. Setting up the RF Gateway to Receive ID TransmissionsThe RF Gateway board is designed to simu-late four 16AI Analog Input boards, each of which has sixteen inputs, for a total of 64 inputs per gateway. To commission a sensor, you must use the Hand-Held Terminal to associate the sen-sor ID number with a "board and point" input ad-dress on the gateway.1. Plug the Hand-Held Terminal into the HHT jack on the RF Gateway. The HHT should power up and display the opening screen.2. Press the DOWN ARROW key to display the Options menu.3. Press the RIGHT ARROW, 1, DOWN ARROW, and DOWN ARROW to select the "Set Sensor ID" option and navigate to the ID Entry Method screen.4. In the ID Entry Method screen, press RIGHT ARROW, 2, DOWN ARROW, and DOWN ARROW to select the "Service Pin" method and navigate to the Enter Start-ing Board Address menu.5. The Enter Starting Board Address menu allows you to jump to Point 1 of the number of the "board" you wish to configure. The four board numbers reserved by this gateway are shown in parenthesis on line 3 of the screen. To begin commissioning sensors on a "board," press RIGHT ARROW, the num-ber of the board you wish to configure, DOWN ARROW, and DOWN ARROW.6. The commissioning screen for Point 1 of the board number you chose will be visible on the screen. There are two configurable parameters on this screen: TYPE, and ID. Press the RIGHT ARROW key to move the cursor to the TYPE field.NOTE: For simplicity, it is recommended you com-mission a sensor’s digital input value on the point im-mediately after its temperature value. For example, if Sensor A’s temperature value is commissioned as Board 1, Point 1, commission its digital input value as Board 1, Point 2. WARNING! Make sure no one else on site is com-missioning or activating sensors while you are commis-sioning sensors. Otherwise, the RF Gateway may read a service button transmission from the wrong RF Sen-sor and commission improperly.
18 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-007. If you want this board and point input to be the temperature read by the RF Sensor, press 1 to change the TYPE field to "TEMP." If you want this board and point input to be the state of the RF Sensor’s digital output (either its clean switch or defrost termination sensor input), press 2 to change the TYPE field to "DIGITAL." When selected, press the DOWN ARROW key to confirm.8. The cursor should now disappear, and line 4 of the display will read "(PRESS SRVC PIN)." Press and hold the Service button on the RF Sensor for one second and then release. The RF Gateway should receive the Service button message and fill the ID field in with the ID number of the RF sensor.The RF Gateway will wait one minute to receive the Service button signal. If it is not received, the message "SRVC PIN TIMEOUT" will appear (you may also manually cancel the wait time by pressing CANCEL.) If commissioning was unsuccessful, press the UP ARROW key and repeat steps 7 and 8. If the sensor will still not commission, refer to Appendix B for troubleshooting information, or attempt to commission the sensor using the Manual Entry method (Section 5.2.).9. Press the DOWN ARROW key again to move on to the next point on the board. Fol-low steps 6 through 8 again to commission the next board point. If you wish to switch to a different board, pressing F2 will move you back to the Enter Starting Board screen described in step 4. 5.3.2. Hand-Held Terminal Screen Navigation Tips• At any time, pressing F1 on the HHT will move you back to the opening screen.• Any time you are entering data in a field where the arrow cursor is visible, pressing CANCEL will clear the field. During commissioning, pressing CANCEL with the cursor in an ID field will delete a sensor from the RF Gateway’s memory (see Sec-tion 5.5., Decommissioning a Sensor from the RF Gateway).5.4. Verifying Successful CommissioningImmediately after being commissioned, the RF Gateway will begin grabbing sensor trans-missions from its associated RF Sensors. You may verify that all RF Sensors you have com-missioned for this gateway are communicating properly by viewing their status using the Hand-Held Terminal. Refer to Section 7.4. for instruc-tions on how to do this.5.5. Decommissioning a Sen-sor from the RF GatewayRF Sensor records may be deleted or "decommissioned" from the RF Gateway’s memory. The process of decommissioning a sen-sor is similar to commissioning, except instead of entering ID numbers, you must delete them.5.5.1. Decommissioning Manually NOTE: For simplicity, it is recommended you com-mission a sensor’s digital input value on the point im-mediately after its temperature value. For example, if Sensor A’s temperature value is commissioned as Board 1, Point 1, commission its digital input value as Board 1, Point 2.
Decommissioning a Sensor from the RF Gateway Commissioning the RF Sensors • 19Entered ID NumbersIf you commissioned the sensors using the Manual Entry method, follow the instructions in Section 5.2. to navigate to the commissioning screen of the sensor input you wish to delete.Press the RIGHT ARROW key twice until the arrow cursor points to the ID number entered for the sensor. Press CANCEL to erase this number. The sensor input is now decommis-sioned. If this sensor has both a temperature and a digital value input commissioned, repeat this process for the second input.5.5.2. Decommissioning ID Num-bers Entered By Service PinIf you commissioned the sensors using the Service Button method, follow the instructions in Section 5.3. to navigate to the commissioning screen of the sensor input you wish to delete.Press the RIGHT ARROW key twice until the arrow cursor points to the ID number entered for the sensor. Press CANCEL. This will both erase this number and cause the RF Gateway to prompt you to press the service button. If you wish to commission a different input to this board and point, you may press the service pin of the new sensor now to commission it. Other-wise, if you wish to leave this board and point empty, press CANCEL again to end the wait time. If this sensor has both a temperature and a digital value input commissioned, repeat this process for the second input.
20 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-006 Connecting Sensors to Einstein/REFLECSThe commissioning process described in Section 5 assigns each sensor a virtual "board and point" address in an RF Gateway’s memory. Once a sensor is commissioned, the controller on the RF Gateway’s RS485 I/O Network treats the RF Gateway in all respects as a series of four 16AI Analog Input Boards numbered in succes-sion.Programming Einstein and REFLECS appli-cations to use RF Sensor values is exactly the same process as programming Einstein and REFLECS applications to use conventional tem-perature sensors connected to 16AI input points; just enter the virtual board and point address of the RF Sensor in the input definition fields. Refer to your site controller’s user manual for information about setting up board and point addresses for inputs in Einstein and REFLECS applications.
Status LEDs Operation and Maintenance of the RF Sensor System • 217 Operation and Mainte-nance of the RF Sen-sor System7.1. Status LEDs7.1.1. RF SensorsAll RF Sensor models have a single LED on top of the enclosure. This LED will flash once ev-ery three seconds to indicate the sensor is operat-ing in Clean mode. Aside from Clean mode, there are only three events that will cause the LED to be ON.1. The LED will be ON for one second when you activate the sensor (see Section 4.2., Ac-tivation).2. The LED will flash twice when you switch the sensor into Sleep mode (see Section 7.5., RF Sensor Sleep Mode).3. The LED will flash once each time you press the Service Button while the sensor is in Ac-tive mode. This indicates the sensor is not in Sleep mode.7.1.2. RF ReceiversThe RF Receiver has three LED indicators: the STATUS LED, the RF LED, and the TOKEN RING LED.7.1.2.1. The Status LEDThe STATUS LED flashes GREEN once per second to indicate the receiver is ON. If this light does not flash, the receiver is unpowered.7.1.2.2. The RF LEDThe RF LED flashes RED every time it receives a transmission from an RF Sensor. In a properly working system, this light should flash occasionally several times over the course of 3-5 minutes. If after five minutes the LED does not flash at all, there may be a problem with the receiver.7.1.2.3. The Token Ring LEDThe TOKEN RING LED flashes ORANGE when it sends transmission data to the RF Gate-ways. The rate at which this light turns ON depends on the number of receivers on site, because RF Receivers take turns sending col-lected data to the gateways. In a properly work-Figure 7-1 - RF Receiver LED Locations
22 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-00ing system, if this light does not come on at all for one minute, there may be a problem with either the RF Receiver or the Token Ring Net-work.7.1.3. RF GatewayThe RF Gateway has four LEDs: a General Status LED, an ALARM LED, an RS485 I/O NET STATUS LED, and a TOKEN RING STA-TUS LED (Figure 7-2).7.1.3.1. The General Status LEDThe General Status LED light flashes GREEN once every second to indicate it is pow-ered up.7.1.3.2. The Alarm LEDThe Alarm LED (red) indicates when an alarm condition exists for the RF Gateway. There are five possible LED states, each of which indicates a different condition.• OFF - No alarm conditions are active, and the RF Gateway is functioning normally.• Flashes 4 times/second - There is a problem with the physical hardware (ROM) of the RF Gateway board. The board may need to be replaced.• Flashes 2 times/second - There is no user configu-ration on this RF Gateway - no sensors are commis-sioned in its memory, and it is essentially in an empty state. This LED state will occur when the board is first powered up on-site.• Flashes 1 time/second - The RF Gateway is not communicating with the area controller due to a pos-sible RS485 I/O Network or controller failure.• ON with no flashing - The RF Gateway is not de-tecting any traffic on the Token Ring Network. Check Token Ring Network connections.7.1.3.3. RS485 I/O Network Status LEDThe RS485 I/O Network Status LED flashes ORANGE to indicate traffic on the I/O Network. If this light does not come on at all and the ALARM LED is flashing once per second, there is a problem with the RS485 I/O Network or the area controller.7.1.3.4. Token Ring Network Status LEDThe Token Ring Network Status LED will flash ORANGE briefly every time a message is passed across the Token Ring Network. How-ever, when the RF Gateway receives a message that it detects as a message from one of its com-missioned sensors, the LED will flash brightly for 1/2 second.If the RF Gateway has commissioned sen-sors and is communicating properly, you should see this LED flash brightly several times within the course of a few minutes.7.2. Clean Switch OperationThe clean switch input on the RF Sensors allows you to manually suspend all temperature alarming on the case so that the case may be cleaned or serviced. Activating Clean mode for an RF Sensor or product simulator is slightly different depending on whether the clean switch contacts are internal (i.e. activated by pressing the Clean button on the enclosure) or external.Figure 7-2 - RF Gateway LED Locations
Battery Life and Replacement Operation and Maintenance of the RF Sensor System • 237.2.1. Internal Clean SwitchFor sensor models equipped with "Clean" buttons, press and hold the Clean button for 3 seconds to switch the sensor from Normal mode to Clean mode. After 3 seconds, the sensor LED should start flashing to indicate Clean mode is active.While the sensor is in Clean mode, pressing and holding the Clean button again for 3 seconds will switch the sensor back into Normal mode. The LED should no longer flash when the sensor has successfully switched to Normal mode.7.2.2. External Clean SwitchAn externally wired clean switch may be either a push button or a static switch. If the clean switch is a push button, press and hold the button for 3 seconds to switch from Normal to Clean mode. To switch from Clean mode back to Normal mode, press and hold the button for 3 seconds.If the clean switch is a static switch, the sen-sor will go into Clean mode when the switch is in the CLOSED position for longer than 3 sec-onds. Clean mode will end when the switch is returned to the OPEN position.Like the internal clean switch, the sensor’s LED will flash once per three seconds when in Clean mode.7.3. Battery Life and Replace-mentThe battery life of an RF Sensor depends on the frequency of transmission. Sensors config-ured to transmit once every three minutes (the factory default) will have a battery life of seven years, while sensors configured to transmit once every 40 seconds will have a battery life of three years. Batteries may be replaced by opening the sensor enclosure, removing the battery from the circuit board, and replacing it with a new battery. The battery is a special low-temperature battery available from CPC (P/N 119-5101) — DO NOT USE ANY OTHER REPLACEMENT BATTERY.7.3.1. Reactivating the RF SensorAfter removing and replacing the battery, the sensor will revert back to Sleep mode and will need to be reactivated. Refer to Section 4.2., Activation, for information about how to acti-vate an RF Sensor.7.4. Viewing Status Using the Hand-Held TerminalFor troubleshooting purposes, the RF Gate-way allows you to view the temperature and dig-ital input values of all commissioned RF Sensors with the Hand-Held Terminal.1. Plug the Hand-Held Terminal into the HHT jack on the RF Gateway. The HHT should power up and display the opening screen.2. Press the DOWN ARROW key to display the Options menu.3. Press the RIGHT ARROW, and press 2 to view temperatures in degrees Fahrenheit or 3 to view temperature in degrees Celsius. Press DOWN ARROW twice to navigate to the Enter Starting Board Address screen.
24 • RF Sensor System I&O Manual 026-1702 Rev 0 10-30-004. The Enter Starting Board Address menu allows you to jump to Point 1 of the number of the "board" you wish to look at. The four board numbers reserved by this gateway are shown in parenthesis on line 3 of the screen. To view status of sensors on a "board," press RIGHT ARROW, the number of the board you wish to configure, DOWN ARROW, and DOWN ARROW.5. Point 1 of the board you selected in step 4 should be visible. This screen will display the type of input this point is configured as, and the last recorded value of the sensor.Use the UP ARROW and DOWN ARROW keys to scroll through all 64 "board and point" addresses on the RF Gateway.If a point’s value shows the message "NO UPDATE," this means the RF Gateway has not received a transmission from the RF Sensor for at least several minutes. Refer to Appendix B for troubleshooting information.If a point’s value shows the message "NOT CFG," this means the point you are viewing was never configured or commissioned and is essen-tially “empty.” If this point is supposed to be commissioned, follow the instructions in Sec-tion 6 to commission the point.7.4.1. Viewing Update CountsIn addition to viewing the current values of all RF sensors and inputs with the HHT, you may also view how many sensor value updates the RF Gateway has received for a sensor. This will allow you to troubleshoot an RF Sensor by analyzing its performance over a period of time.To make the HHT show sensor value updates, locate switch #5 on the RF Gateway dip switch, and set this switch to the ON position (Figure 7-3). The HHT will now show sensor update counts instead of temperature or digital input values on the status screens. Follow the instructions given in Section 7.4., Viewing Sta-tus Using the Hand-Held Terminal, to view update counts for each sensor.TIP: While viewing the status of points, if you wish to switch to viewing points on a different board, press F2 to navigate directly to the Enter Starting Board screen.Figure 7-3 - Show Updates Dip Switch on RF Gateway
RF Sensor Sleep Mode Operation and Maintenance of the RF Sensor System • 25The number in the VALUE field is the num-ber of updates the RF Gateway has received from the commissioned sensor since the last time the sensor’s count was reset to zero.7.4.1.1. Resetting the Sensor Update CountThe update count for a sensor can be reset in two ways. To clear an individual input’s count, navigate to the input’s HHT status screen and press CANCEL. The VALUE field should reset to zero. A power loss to the RF Gateway will reset all update counts back to zero. 7.5. RF Sensor Sleep ModeEach RF Sensor is shipped from the factory in a deactivated state called Sleep mode. During Sleep mode, the sensor will not broadcast or do anything that will drain the battery. Section 4.2. explains how to activate a sen-sor that is in Sleep mode. To return an active sensor to Sleep mode, press and hold the Service button on the sensor enclosure for ten seconds. The sensor’s LED will flash twice to indicate the sensor has entered Sleep mode.NOTE: The Show Updates switch does not affect the values being sent from the RF Gateway to the site con-troller. The RF Gateway will only send temperature val-ues and digital input values to the site controller, not update count values.Figure 7-4 - Putting a Sensor in Sleep Mode
