Functional Block Diagram of Typical Electronic Bypass Option. The SED2 Electronic Bypass (E-Bypass) Option consists of a SED2 VFD, and a bypass enclosure with electronic controls (Figure 2). The electronic controls include: • OVERLOAD RELAY VFD VFD0093R1 During normal operation in a typical application, the input and output contactors close and the SED2 operates the motor (Figure 1). The bypass contactor provides the ability to operate the motor on utility power and eliminate the SED2 from the motor control circuit. The SED2 Electronic Bypass Option also allows you to select features that enhance the control of the contactors and the outputs that report operation. OVERLOAD (CURRENT) RELAY DISCONNECT SWITCH (OR OPTIONAL CIRCUIT BREAKER SHOWN) Figure 2. Typical SED2 E-Bypass Components. Siemens Building Technologies, Inc. Electronic Bypass Option Overview Controller Board The Controller board is the foundation of the SED2 Electronic Bypass Option. It controls communications to and from the SED2, keypad, isolated digital inputs, relay/digital outputs, and contactors (Figure 3). SED2 INTERFACE Supports two SED2 non-isolated, digital relay outputs and three SED2 digital inputs. The maximum current draw for a relay output is 2 mA and the voltage between the digital output source and return lines is 24V. The Controller board provides unregulated, non-isolated 24V to power the SED2 digital inputs. J4 CONTROLLER BOARD BASIC SANITY TEST INDICATOR Provides indication of initialization and normal operation. FACTORY USE ONLY Connector J8 is for factory use only. DIGITAL INPUTS Supports six isolated digital inputs for customer use. The inputs require a contact closure capable of providing a low impedance path at currents less than 20 mA. J3 MCU ON OFF J8 SW1 KEYPAD INTERFACE Supports inputs and outputs from the Electronic Bypass Option keypad. The keypad provides user interface indicators and push buttons. J2 J1 TRANSFORMER DIGITAL RELAY OUTPUTS Supports six digital relay outputs for customer use. Each relay has a maximum rating of 2A at 120 Vac.

F1 When the switch is ON the option is enabled; when the switch is OFF the option is disabled. Figure 3. Controller Board Inputs and Outputs. Siemens Building Technologies, Inc. 5 SED2 VFD Electronic Bypass Option Operating Instructions Contactors The Controller board provides two or three relay contact circuits controlled by the Electronic Bypass Option: bypass, input, and output contactors. Each circuit includes a NO relay. Controller board connector J7 enables circuit connections. The relay circuits route power to the SED2 and the motor via the contactors. Controlling the contactors through the relay circuits is the main function of the Controller board. Bypass Contactor – The bypass relay on the Controller board controls the bypass contactor. The output and bypass relays are interconnected to 120 Vac Hot. This enables a safety circuit that prevents the bypass and output contactors from simultaneously being energized. Output Contactor – The output relay on the Controller board controls the output contactor. Input Contactor – The input relay on the Controller board controls the optional input contactor.

E-Bypass Keypad Indicators and Pushbuttons. The keypad provides user interface indicators and pushbuttons. The following table describes specific pushbutton and indicator functions: 6 Siemens Building Technologies, Inc. Electronic Bypass Option Overview VFD0102R1 VFD0101R1 VFD0100R1 VFD0099R1 VFD0098R1 Pushbutton/Indicator Input On/Off The Input On/Off pushbutton is supplied with the optional drive input contactor. In VFD mode, this switch does nothing. In bypass mode, this switch closes/opens the input contactor, switching the SED2 power on/off. Enable Enables SED2 operation by closing the input and output contactors. Hand Start Manually enables bypass mode operation by ensuring that the output contactor is open and then closing the bypass contactor. Remote Start Activates the bypass mode and operates the bypass contactor according to the status of the Remote Start input on the Controller board. STOP RESET Opens the output and bypass contactors, disconnecting the motor. VFD0103R1 VFD Fault Safety Fault VFD0104R1 Safety Fault Overload Fault VFD Fault VFD0105R1 When a VFD Fault is indicated, the VFD Fault indicator lights and the VFD Fault Relay output on the Controller Board is triggered. Overload Fault VFD Fault Safety Fault The Safety Fault indicator lights when either of the Remote Safety inputs on the Controller board opens. The motor is prohibited from operating in either the VFD or bypass modes while either of these contacts is open. EXCEPTION: Essential Services ignores a Safety Fault. NOTE: If not using the Remote Safety feature, hard wire the two Remote Safety inputs. If the Electronic Bypass Option current overload relay trips, the Overload Fault indicator lights and the motor will not run in bypass mode. Overload Fault Auto Bypass Enabled VFD0106R1 Description Essential Services When the Auto Bypass DIP switch is enabled, the Auto Bypass Enabled indicator is on steady. Bypass operation is automatically initiated by the SED2. When Auto Bypass is active, the Auto Bypass Enabled indicator flashes. When the Essential Services DIP switch is enabled, the Essential Services indicator is on steady. VFD0107R1 Auto Bypass Enabled Essential Services When the Essential Services input is open, normal operation is indicated as the output contactor remains closed to keep the motor running and the Essential Services indicator is on steady. When the Essential Services input is closed, the bypass contactor closes and the Essential Services indicator flashes. Nothing can interrupt the Essential Services mode except for the Essential Services input opening. Siemens Building Technologies, Inc. 7 SED2 VFD Electronic Bypass Option Operating Instructions Pushbutton/Indicator Description VFD0108R1 When the Interlock DIP switch is enabled, the Interlock Start Logic Enable indicator is on steady. Any call to start the motor in either VFD or bypass modes will not start the motor; instead it will close the Programmable Output relay on the Controller board. INTERLOCK START LOGIC Enable Commanded Proofed The Programmable Output can be used to actuate another device. When this occurs, the Interlock Start Logic Commanded indicator also lights, and the Interlock Start Logic Proofed indicator flashes. A contact closure from this other device is wired to the Interlock Start on the Controller board which then starts the motor and turns the Interlock Start Logic Proofed indicator on steady. This feature is also called damper end switch relay logic. 8 Siemens Building Technologies, Inc.

Startup Procedures Startup Procedures Safety Precautions WARNING: When you connect input power to the Electronic Bypass Option, the motor terminals are energized even if the motor is not running. Do not make any connections with input power connected to the Electronic Bypass Option. Disconnect and lock out power to the drive before servicing it. Failure to disconnect input power may cause serious injury or death. CAUTION: After you disconnect input power, the DC bus capacitors must be allowed to discharge to a safe voltage. This will take about 5 minutes. Installation Inspection Inspect the mechanical and electrical installation for compliance with local electrical codes and regulations. After installation, verify that: • Electronic Bypass Option and motor are properly grounded. • Input power and motor wire sizes are correct and connections are secure. • Control wiring is correct, connections are secure, and wire shield is properly grounded. • Control wiring is not routed with power wiring. • Electronic Bypass Option has proper ventilation. • Internal Bypass connections are secure. Power-On 1. Turn on Electronic Bypass Option power. Power-on initialization performs a basic sanity test (approximately 7 seconds) to initialize the Controller board. Also, the Stop/Reset indicator will flash. A unit fault condition occurs if the Electronic Bypass Option did not pass the basic sanity test. See the Troubleshooting section in this manual for more details. Siemens Building Technologies, Inc. 19 SED2 VFD Electronic Bypass Option Operating Instructions After the basic sanity test, if the DIP switches have not changed and there is no operator intervention, the most recent bypass function is restored. If the DIP switches have changed, the Electronic Bypass Option activates the Stop/Reset function. 2. Press the Enable key on the Electronic Bypass Option keypad to place the unit in VFD mode. 3. Perform SED2 commissioning per the SED2 VFD Startup, Operation, and Maintenance Manual (125-3201). If using the Quick Commissioning mode, end this mode with P3900 = 3 to run a motor calculation without resetting the SED2 to factory defaults. 4. After basic SED2 operation is established and verified, turn SED2 power off via the Electronic Bypass Option input power device and verify that no dangerous voltages are present in the enclosure. 5. Select Electronic Bypass Option application features using the DIP switches. DIP Switch Settings for E-Bypass Features. Switch Position NOTE: Description 1 Essential Services selector switch. 2 Automatic Bypass selector switch; requires SED2 programming. 3 Interlock selector switch; requires SED2 programming. 4 Factory test #1 selector switch. Not used; leave this switch OFF. 5 Factory test #2 selector switch. Not used; leave this switch OFF. When the switch is ON, the feature is enabled; when the switch is OFF, the feature is disabled. For details on the Electronic Bypass Option features, see the Application Feature Setup section in this manual. 6. Re-apply power to the Electronic Bypass Option. On units with three contactors, energize the SED2 by pressing the Input pushbutton on the Electronic Bypass Option keypad. 7. Program the SED2 per the Application Feature Setup section in this manual. 8. Test all SED2 and bypass features. 20 Siemens Building Technologies, Inc. Startup Procedures 9. If motor rotation is incorrect in either VFD, bypass, or both modes, have the appropriate site personnel take corrective action as follows: − Wrong Rotation in Bypass, Right in VFD Mode – Swap two input leads on the main input device of the Electronic Bypass Option. − Wrong Rotation in VFD, Right in Bypass Mode – Swap two input leads on the main input device of the Electronic Bypass Option and swap two motor leads at the motor overload in the Electronic Bypass Option. − Wrong Rotation in both VFD and Bypass Modes – Swap two motor leads at the motor overload in the Electronic Bypass Option. Quick Commissioning Parameter P0010 is the Commissioning Parameter Filter. It allows you to select a group of parameters that can be used for quick commissioning, including motor data, and motor ramp-up and ramp-down settings. It is important to use parameter P0010 to commission the SED2, parameter P0003 to select the access level for using parameters, and parameter P0004 to filter the parameters according to their functionality. When Commissioning Parameter Filter P0010 = 1, it initiates the quick commissioning procedure. It is recommended that you use the quick commissioning procedure. However, experienced users may commission the equipment without the P0004 filter functions. At the end of the quick commissioning procedure, set parameter P3900 = 3. This setting performs the necessary motor calculations and sets all remaining parameters (those not included in P0010 = 1) to the factory default values. If 3900 is set to a value greater than 0, P0010 is automatically reset to 0. (If P0010 = 1, the SED2 cannot start.) The process of performing motor calculations and setting all parameters to factory default values is only possible via quick commissioning.

Siemens Building Technologies, Inc. 33 SED2 VFD Electronic Bypass Option Operating Instructions Automatic Restart Continued Parameter P1210 (Continued) Description Action Setting/ Default P1210 = 4, Restart after supply power brownout (P1211 disabled): For these settings it is fundamental that the drive only restarts if it has been in a RUN state at the time of the fault (F0003). The inverter will acknowledge the fault and will restart the drive after a blackout or brownwout. It is necessary that the ON command is wired via digital input (DIN). P1210 = 5, Restart after blackout or fault (P1211 disabled): The inverter will acknowledge the faults (F0003 etc.) at power on after blackout and will restart the drive. It is necessary that the ON command is wired via digital input (DIN). P1210 = 6, Restart after supply power brown/blackout or fault (P1211 disabled): The inverter will acknowledge the faults (F0003 etc.) at power on after blackout or brownout and will restart the drive. It is necessary that the ON command is wired via digital input (DIN). Setting 6 causes the motor to restart immediately. P1210 = 7, Restart after supply power brown/blackout or fault (P1211 enabled): This setting is for use where an external bypass system or process is interlocked with a relay that is set to P0731/P0732=52.3 (fault). The inverter functions the same as P1210=6 (trip on brownout, blackout or fault) but uses P1211 and only sets the fault bit P0731/P0732=52.3 when the specified number of restarts defined in P1211 has expired. If no trip occurs after 2 hours, the fault counter is reset. NOTES: 1. Auto restart requires a constant ON command (such as via a digital input). 2. P1200 flying start must be used in cases where the motor may still be turning, such as after a brief input power break, or can be driven by the load. 3. A supply power brownout is when the power is interrupted and reapplied before the operator panel display has gone dark. It is a very short supply power break where the DC link has not fully collapsed. 4. A supply power blackout is when the operator panel display has gone dark before the power is reapplied. It is a long supply power break where the DC link has fully collapsed. 34 Siemens Building Technologies, Inc.

The reset process takes about 10 seconds. 40 Siemens Building Technologies, Inc. Required SED2 Parameter Settings Required SED2 Parameter Settings The following SED2 parameters are programmed by the factory before shipping. If these parameters are changed or if the SED2 is ever reset to factory default, you must reset these parameters as follows: Parameter Setting P0748 P0702 in000 3 P0702 in001 3 P0731 52.3 NOTES: 1. The Interlock Start on the Controller board is simply a follower that can be used to tell the drive to do anything by closing the SED2 Interlock Start and programming P0704. 2. The Programmable Output on the Controller board is simply a follower of the SED2 Relay. 3. The SED2 Fault must always be programmed as a fault. Do not change the SED2 relay fault for other uses via P0731. 4. Changing P0700 resets all digital inputs and P0702 will require programming.

Controller Board Digital Inputs and Outputs. Auto Bypass without Interlock Description The Auto Bypass feature enables the SED2 to initiate automatic bypass mode operation. Closing of the SED2 Relay sends the motor to hand bypass mode. See the SED2 VFD Startup, Operation, and Maintenance Manual (125-3201) for programming of this relay and for its desired action. When the SED2 initiates bypass mode operation, the following occurs: 42 • The SED2 stops delivering power • The output contactor opens. • The bypass contactor closes and the Programmable Output on the Controller board closes. Siemens Building Technologies, Inc. Application Feature Setup NOTES: 1. All safety conditions must be met for bypass mode operation. 2. The input contactor remains energized. The Electronic Bypass Option will return to VFD mode operation as soon as the SED2 Relay in control opens. When the Electronic Bypass Option returns to VFD mode operation, the following occurs: • The SED2 Relay opens, the Programmable Output on the Controller board opens, and the bypass contactor opens. • The output contactor closes. NOTE: All safety conditions must be met for VFD mode operation. 4 2 3 3 4 During operation, the Auto Bypass Enabled indicator is on steady. 1 SW1 1 VFD0117R1 ON 2 NOTE: 5 5 ON The Auto Bypass feature requires that Controller board DIP Switch 2 is set ON.

Any call to start the motor from the SED2 or bypass does not directly start the motor, but instead initiates the following Interlock procedure: • The Interlock Start Logic Enable indicator is ON. Proofing is required to start in VFD or bypass mode. • The Interlock Start Logic Command indicator turns ON and the Proofing indicator flashes. • When in VFD mode, the SED2 Relay closes and the Controller board Programmable Output closes to initiate the proofing sequence. The Programmable Output relay is used to supply power to an external device such as a damper actuator. • When not in VFD mode, the Controller board ignores the SED2 Relay. • When in bypass mode, any call to start the motor in bypass (in either hand bypass or auto bypass) initiates the proofing sequence. The Programmable Output closes and is used to supply power to an external device such as a damper actuator. • When control of the external device (such as a damper actuator) is satisfied, it must supply a contact closure to the Controller board Interlock Start. The Interlock Start Logic Command indicator turns OFF and the Proofing indicator turns ON. The motor then starts in the selected mode. • Any call for the motor not to be running requires a new proofing sequence to be initiated. NOTE: This feature can only be used with a hardwired start/stop command. ON 4 5 5 44 1 SW1 1 VFD0118R1 1. The Interlock Start Logic Enabled indicator is on steady.

Example assumes hardwired start is in auto. If other, modify P0732 as appropriate. For proper Interlock operation, set the following SED2 parameters: • P0700 in000 = 2 Digital input that is the start command in the auto mode (from the damper end switch) • P0700 in001 = 2 Digital input that is the start command in the hand mode (from the damper end switch) • P0701 in000 = 99 and P0701 in001 = 99 Initiate BiCo • P0702 in000 = 3 and P0702 in001 = 3 • P0732 in000 = 722.0 Tells the drive through BiCo that instead of starting the drive in auto mode when the Remote Start input closes, it should close the SED2 Relay. NOTE: If P1 is the start command in auto, change the following parameters: P0003 = 4 (before changing this setting, note the current setting) P3950 = 46 P0732 in000 = 2090.0 P0003 = Change back to previous setting (1, 2, or 3) • P0732 in001 = 19.0 Tells the drive through BiCo that instead of starting the drive in hand mode when the green Start button is selected, it should close the SED2 Relay. • P0704 in000 = 1 and P0704 in001 = 1 NOTE: For a complete description of BiCo, see the SED2 VFD Startup, Operation, and Maintenance Manual (125-3201).

Activation of Essential Services overrides any other selected operation. Essential Services ensures that the bypass contactor will not open when a safety input or overload opens. Power goes directly to the motor. NOTES: 1. If using both the Interlock and Essential Services features, Essential Services waits 10 seconds for the Interlock to confirm the safety condition (such as opening a damper). After the 10-second delay, Essential Services controls the motor regardless of the Interlock safety condition status. 2. Use extreme care when using the Essential Services mode.

Siemens variable speed drives of the product range SED2 (Micromaster 436) fulfil the requirements of the EN 61000-3-12 (without the need for external line reactors) regarding the THD values of Table 3 under the pre condition of Rsce > 190. The required PWHD values will not be achieved. Due to this fact it is recommended to apply for connection approval at the local electricity board. The local electricity board will evaluate among many other data the content of the 5th harmonic current and the Line Power Factor "Lambda”, which is the ratio of active power and apparent power. Siemens frequency inverters are optimized in design and operation characteristics regarding energy efficiency and less interference with line supplies. 50 Siemens Building Technologies, Inc. Troubleshooting Troubleshooting WARNING: Always disconnect all power sources before opening the SED2 Electronic Bypass Option. Power-on Initialization Failure (Unit Fault Condition) During power-on initialization, a unit fault condition occurs if the Electronic Bypass Option did not pass the basic sanity test. Rather than flash normally, the basic sanity test indicator pauses, flashes a fault code, and then repeats. Table 7 shows the fault codes. For example, if the basic sanity test indicator flashes three times rapidly, pauses, and then repeats, this means that there is a keypad failure. Table 7. Basic Sanity Test Fault Codes. Basic Sanity Test Fault Code/Flashes Description 1 Non-Volatile Memory Failure 2 Flash Memory Failure (CRC, cyclic redundancy check) 3 Keypad Failure 4 RAM Memory Failure (not used) 5 EEPROM Read error 6 EEPROM Write Failure 7 Runtime Flash Failure (CRC, cyclic redundancy check) 8 Main Program Failed (or hangs) It may be possible to recover from the unit fault condition by simply attempting a power down/up of the Electronic Bypass Option. If the unit fault condition still exists, replace the Controller board. CAUTION: When powering down/up the Electronic Bypass Option, power down the unit, wait 5 minutes, and then power up the unit. Siemens Building Technologies, Inc. 51 SED2 VFD Electronic Bypass Option Operating Instructons Override Jumper An Override Jumper (J8) is supplied on the Controller board.

If the basic sanity test indicator (Figure 15) is flashing, fuse F1 is OK and no action is required. 2. Verify that 120 Vac power is available on the secondary side of the Electronic Bypass Option power transformer (Figure 15). If power is not proper, check the Electronic Bypass Option components such as: • Power transformer • Power transformer fuses (F2, F3, and F4). Table 8 provides fuse replacement information. 3. If power is proper, check fuse F1 as follows: • Power down the Electronic Bypass Option. • Remove the Controller board cover. • Remove fuse F1. • Use an ohm meter to check the fuse. • Replace fuse F1 if necessary.
