The handling and orientation of the DTMAC controller is provided on the field assembly sheets and in this document. Document # Rev 02 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 2.0 Configuring the DTMAC Tracker Controller Important! Do not attempt to change any of the DTMAC controller’s specified parameters. Doing so could dramatically alter system functionality and its ability to gather energy. Contact the DTMAC Monitoring team if you have questions about controller parameters. You must wire the DTMAC controller and set the parameters so that the tracking functionality will execute properly. Once configured, new controllers are administered in the SunPower DTMAC Advanced Tracker Controller monitoring application to complete the commissioning procedure (refer to Appendix B). 2.1 Mounting the Controller The DTMAC needs to be mounted to the pier using the two clamps (Fig. 2) which come with the DTMAC packaging. Mount the DTMAC at the specified height from ground level and at the specified location on the pier, this information should be obtained from the project drawings. The DTMAC needs to be mounted vertical (Fig. 3) and it should be facing the geographical direction as specified in the project drawings. 2.2 Wiring the Controller Before performing the steps in this section, refer to the project drawings to identify the following: the controller designated as the “Coordinator” DTMAC for the network the controller to be installed with a GPS unit the mounting orientation of the DTMAC box and identifying the East, West branch motor wires the controller to be installed with a String Monitor connection. These units have unique hole-drilling and wiring requirements. Document # Rev 02 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION Shipped separately, the DTMAC/TMAC Coordinator Upgrade Kit (SunPower part # 111437) contains components required for Coordinator conversion of the specified DTMAC unit and to facilitate GPS installation into another DTMAC: XBee® Coordinator radio chip (enclosed in antistatic bag) GPS unit (with cable and modular jack) Cable gland for the GPS cable GPS Magnetic Mount Kit (with three attachment screws for the main unit) a. Cable gland for the Ethernet cable b. Snap-on Ferrite c. Ferrite Safety Key (used to open the closed ferrite) Document # Rev 02 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION Important! To minimize the risk of damage to internal wiring and other components in the controller box, drill all necessary holes before attaching wire leads. To reduce fiber dust during drilling, SunPower recommends that you use a hole saw. 4” The DTMAC controller comes preassembled with the East and West motor wiring branches already attached. To connect the wiring to the DTMAC controller: 1. Drill a hole of appropriate size for the input 480VAC power entry cable or conduit (as specified in the project drawings) approximately 4″ (10 cm) to the right of the west branch motor cable entry (Fig. 4) Fig. 4 2. If the controller you are installing is not the designated Coordinator DTMAC or GPS unit, proceed to Step 6. 3. If the controller is the Coordinator DTMAC or the designated GPS unit, drill another hole to the left of the east branch motor CAN cable entry (Fig. 5) according to the following requirements: 2” If the controller is designated as the GPS unit: Drill a hole 7/8″ (22 mm) in diameter for the GPS cord grip (Fig. 5) contained in the DTMAC Coordinator Upgrade Kit. Fig. 5 If the controller has a string monitor board connection drill a hole 7/8″ (22 mm) in diameter 2” (5 cm) above and 2” (5 cm) to the right of the east branch motor CAN cable entry for the string monitor cord grip (Fig. 6) 2” If the controller is the Coordinator DTMAC: 2” a. Refer to the electrical wiring diagram to determine if an outdoor rated Cat 5 Ethernet cable or a specified conduit fitting is to be installed for Internet connectivity. b. If Cat 5 Ethernet cable is to be used, drill a hole 7/8″ (22 mm) in diameter Fig. 6 for the cable gland (included in the kit); if conduit fitting is to be used, drill a hole of appropriate size for the conduit that serves as the raceway for the Ethernet cable (Fig. 5). Document # Rev 02 10 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 4. Install the cable or conduit fitting for the power entry wiring provided at the site. Bring the 3-phase power entry leads out of the fitting and then land the L1, L2, and L3 leads, on the correct terminals of the circuit breaker (Fig. 7, Marked in a Red box). A black label under the circuit breaker identifies the terminal locations. The GND wire must be terminated with a 10-32 ring terminal and mounted at the grounding stud location. The grounding stud is marked with the appropriate label. GROUNDING STUD Important! Ensure that you land the wires on the correct terminals. Note. There should be ferrules installed on the power wires. 5. Apply 25 in-lbs (2.8 N-m) torque to all of the recently attached terminals while securely holding them against the terminal blocks. Firmly pull on the wires to make sure that all are securely attached. Fig. 7 Only perform Step 6 on the controller designated as the GPS unit. GPS CABLE 6. To install the GPS cable: ETHERNET CABLE a. Install the cord grip into the hole for the GPS cable (to the right of the inclinometer hole). STRING MONITOR CABLE b. Hand-tighten the locking nut until it is flush against the inside wall of the enclosure and then tighten 1/6 turn with a wrench. c. Feed 12″ (30.48 cm) of the GPS cable through the mounted cord grip. d. Tighten the cord grip dome until it is flush with the fitting and in contact with the gland base. Fig. 8 e. In the box, route the cable between the lower right PCB standoff and the enclosure wall. Route the cable counterclockwise around the lower standoff and under the PCB. From underneath the PCB, route the cable to the topside (Fig. 8). Use the cable holders which come with the DTMAC packaging to secure the cable to the back panel and to route the cable. f. Insert the RJ45 plug into the modular jack labeled RJ3-GPS (Fig. 8). Fig. 9 Only perform Steps 7–8 on the controller designated as the Coordinator DTMAC. 7. To install the Ethernet cable: Document # Rev 02 11 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION Install the cord grip (if being used) into the hole to the right of the east branch motor CAN cable entry hole. Hand-tighten the locking nut until it is flush against the inside wall of the enclosure and tighten 1/6 turn with a tool. If conduit is being used, install the fitting similarly but tighten 1/2 turn with a tool. a. Feed the Ethernet cable through the SunPower provided cable gland (or conduit—in which case the gland is not needed) and route the cable between the front standoff and the enclosure wall (Fig. 8). b. Coil any excess cable and restrain with the cable holder or zip tie to maintain isolation from the power circuits in the enclosure. Fig. 10 c. Continue to route the cable underneath the PCB and to the left side of the upper right standoff (not between the upper standoff and enclosure wall), and then bring the cable to the topside of the PCB (Fig. 8). d. Wrap the cable three times around the snap-on ferrite (Fig. 9, and Fig. 10) so that when finished less than one inch of cable protrudes between the ferrite and the plug end (Fig. 11). e. Insert the cable end into the modular jack on the NetBurner® module (Fig. 12). Fig. 11 Fig. 12 Document # Rev 02 12 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 8. To install the Coordinator radio chip: a. Remove the factory-installed XBee® router module (Fig. 13). Place an index finger against the router module’s edge between the DIRECTION and MODE switches and other index finger against the opposite edge near the NetBurner® module. With a slight back and forth rocking action, slowly lift the pins out of the socket a small amount each time (Fig. 14). Important! Ensure that you handle the router module carefully to avoid damaging the antenna attached to the PCB. Fig. 13 b. Check that the antenna is perpendicular to the PCB. Carefully straighten the antenna if needed. c. Remove the XBee® Coordinator radio chip from the antistatic bag and position it over the socket. d. Make sure that all of the module pins are aligned with the pin receptacles of the socket (Fig. 15), and not shifted over by one pin e. With a slight back and forth rocking action, firmly press on both socket rows simultaneously. f. Verify that all module pins are directly over the pin rows of the socket strips (Fig. 15). The module’s physical shape should directly coincide with the outline on the PCB silkscreen overlay. Tug on the wires gently to ensure that they are properly seated. Fig. 14 9. Check all installed cables before closing the enclosure Fig. 15 Document # Rev 02 13 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 2.3 Connecting the East and West Branch Motor Cables There is 1 pair each of the East and West branch motor cables already attached to the DTMAC controller. These cables have connectors already installed at the external end and need to be connected to the East and West branch extension cables and to the DC smart motor as per the project drawings. Warning! The power should be turned OFF at the DTMAC controller by switching the respective circuit breakers (to which these cables are connected inside the DTMAC controller) to the OFF position, before connecting these cables to either the motor or the East and West branch extensions. 2.4 Smart Motor Configuration Procedure The DC Smart motor needs to be pre-configured in order to communicate properly with the DTMAC system.. 2.4.1 Overview In order for the TMAC system to function properly each of the 16 motors must be leveled to a reference tracker surface datum, given a node ID based on the position in the array of 16 trackers, and have the full operational range verified. Because this does not require communication with the DTMAC it can be done independently at the tracker using a PC with a software tool (or skilled operator) that compares a temporary reference sensor to the motor sensor. 2.4.2 Motor Configuration In order for the PC to command the motor, the CANbus Y-connector on the motor must be unplugged and the cable from the PC used in its place. If field power is active the motor power cable can remain in place – otherwise a mobile 24V supply is required to power up the motor during commissioning. The PC is used to command the motor to drive to a position where the reference sensor is level (0°) and then a command is issued for the motor to reset the internal sensor to zero. Due to the use of a hysteresis value when tracking, the motor must be at least 0.15 deg away from a reference point in order for the motor to attempt a repositioning move. For this reason the motor is first commanded to drive to +1 deg. When the motor resets the inclinometer, the setting is stored in non-volatile memory in the sensor and will not be lost if the power is cycled. A safety feature integrated in the motor firmware will prevent the reset from occurring if the angle of the internal sensor reads more than 2 degrees. If the reset is attempted beyond 2 degrees the motor will go into an error state and store the value -20005 in the motor error register (0x3001.0). Figure A shows a schematic of a potential automated system that an operator can start with a few clicks from an interface along with the sequence of commands to level the motor. Table 1 lists the logic and communication steps required for an automated or manual process. Document # Rev 02 14 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION Ref. Sensor on Tracker Datum Motor on Tracker PC with interface to motor & ref sensor FIGURE A: Automated motor commissioning system tool. TABLE 1: Motor commissioning steps. Description Motor Command or Operation Operator clicks on “Commission Motor” Interface button Ask operator if motor is new (ID =127) or motor is being re-leveled (old ID must be given for re-leveling) Step User interface input OLDorNEW variable set If OLD, Store motor ID as MOTOR_ID Tracking command sent to motor SDO-W, NodeID=127, 0x5101.1, 0x05 Motor given setpoint (SP) of +1 deg SDO-W, NodeID=127, 0x5105.1, 100 SDO-R NodeID=127, 0x5102.1 Monitor motor register MY_STATUS to know when SP reached.

If valid and different by more than 1 from previous tracker ask user to verify. SDO-W NodeId_old, 0x2000.1, 0x6E657277 SDO-W NodeId_old, 0x2000.2, NodeId_new Response may require 2 sec. Command motor to reassign node ID 17 Reset device afterwards: SDO-W NodeId_old, 0x2009, 1, 0x6E657277 SDO-W NodeId_old, 0x2009, 2, 0x9999 Save Preset value, RSP, with tracker and block number to record file Document # Rev 02 16 Software operation 18 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION After the motor is leveled and given a proper node ID, the full range of motion must be verified. If there is any blockage in the system (such as the hard stop in the slew drive) the motor will likely error out with -4000 (check error register 0x3001.0). The error must be cleared before the motor will move again. If a hard stop is hit at one of the maximum extents the motor maximum angle must be changed to prevent repeated errors. Resetting the max motor angle requires a motor MPU firmware update (see Dunker “Project description file”). The full operational range test is best performed via the TMAC jog switches as it takes a considerable amount of time for the motor to complete the 300 degree path while moving at a controlled speed of 4 deg/min (stow to +75 to -75 to stow). Both max positive and negative rotation positions should be verified using the jog switches. Trackers that hit the hard stop should be fine to rotate to the opposite max extent. Any hard stop hits will be clearly distinguishable by the orientation the tracker is stuck at when the DTMAC jog switch is cycled back to stow. 2.5 Setting Parameters and Verifying Functionality After you install the DTMAC controller, you must assign the controller a node address, level the system, verify east and west tracking limits, and enter other operational parameters. You must assign a node address, perform the verifications, and enter the parameters for each DTMAC controller on the site. Once entered, the data is stored in the non-volatile memory of the DTMAC through an update command. Important! The GPS device installed in designated DTMAC controllers enables the controller to acquire the longitude, latitude, and time, and to wirelessly provide the information to the Coordinator DTMAC. The Coordinator DTMAC then transmits the data to all controllers in the network. Configure the Coordinator and DTMAC GPS units first so these data can be available as other controllers are configured. A DTMAC controller without time information will not run in Auto mode. Note. DTMAC controllers installed with GPS units are usually assigned node address NODEID 1. You set system parameters by connecting a laptop to the DTMAC controller. The laptop you connect must have the DTMAC term application installed. The DTMAC term application enables easy configuration of the DTMAC and quick verification of system functionality. Important! The laptop you use must be configured for DTMAC programming. Refer to Section 2.5 for the configuration procedure. Here is a closer view of the DTMAC controller logic board (Fig. 16): Fig. 16 DTMAC Tracker controller PCB Document # Rev 02 17 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION The state of the DTMAC controller can be manipulated with two 3-position rocker switches: the MODE Switch and the DIRECTION Switch. The DTMAC controller has three primary operating modes, activated with the MODE Switch: AUTO Mode (the middle or neutral position) runs the motor to drive the array that maximizes system power output (the controller computes the sun’s position and moves the array accordingly) MANUAL Mode enables the position of the array to be manually adjusted using the DIRECTION Switch: o EAST (up) runs the motor to tilt the panels to the east o OFF (the middle or neutral position) turns the tracker motor off o WEST (down) runs the motor to tilt the panels to the west There is a time delay enforced if the DIRECTION Switch is too rapidly moved. STOW Mode runs the motor to the preconfigured ‘flat’ position Important! Before setting parameters, refer to the project drawings to identify the designated Coordinator DTMAC unit for the network you are configuring. The Coordinator DTMAC unit, located at the closest inverter station, is hardwired with Ethernet cable to the site access point (refer to Section 2.2, Step 7). Verify that the unit has the XBee® Coordinator radio chip (marked with a “C“, Fig. 17) instead of the factory-installed XBee® router module (refer to Section 2.2, Step 8). Fig. 17 2.5.1 Setting System Parameters Power on the controller and verify that the LED marked D_3V near the power supply is lit. To set the system parameters for each DTMAC controller: 1. Power down the controller. 2. Refer to the project drawings for the following: Network Address (PANID) – the address of this group of DTMAC units Node Address (NODEID) – the address of the DTMAC being configured Fig. 18 Important! NODEID 0 is always reserved for the Coordinator DTMAC unit. 3. Put the MODE Switch in the MANUAL position. 4. Referring to the Individual Tracker Information Table, perform the following steps on the DTMAC address switches: a. Set the PANID Switch: All of the controllers in a network have the same PANID. Set all of the units in that group to that same PANID using the following table to convert from PANID decimal to binary switch position. PANID Number (Decimal) Binary Switch Position 00000001 00000010 00000011 00000100 00000101 00000110 00000111 Document # Rev 02 19 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 8 00001000 00001001 10 00001010 The rightmost digit in the Binary Switch Position value corresponds to the rightmost binary switch (labeled 8). The “up” position (towards ON) of each switch represents a binary 1, and the “down” position a binary 0 (Fig. 18). Fig. 19 For example, the PANID Switch is set to 00000011 on a controller that belongs to a network with PANID 3 (Fig. 18). Important! To convert PANID decimals 11 to 255 to binary switch position, refer to Appendix A. b. Set the NODEID Switch: On the Coordinator DTMAC unit, set the NODEID binary switches to 00000000 (all switches down). For all of the remaining DTMAC units within this PANID, consult the project drawings for each controller’s assigned NODEID. Refer to the following table to convert from NODEID decimal to binary switch position. The individual Binary Switch Position value correlates with the individual switch positions as you go from left (switch 1) to right (switch 8) (Fig. 19). Document # Rev 02 NODEID Number (Decimal) Binary Switch Position 00000001 00000010 00000011 00000100 20 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 5 00000101 00000110 00000111 00001000 00001001 10 00001010 Fig. 20 For example, the NODEID Switch is set to 00000101 on the controller that is assigned NODEID 5 (Fig. 19). 5. Use the USB-A to USB-B cable assembly to connect the laptop to the controller through the Programming Port. 6. Start the DTMAC term application. Note: For Windows 7 users, one need to have UAC disabled on their system in order for the virtual COM port drivers to be installed by the DTMAC. 7. The DTMAC term Select serial port screen opens (Fig. 20): Select the serial port number being used by your computer for DTMAC term and then click OK. Skip Steps 8–11 and proceed to Step 12. To determine the serial port number being used by your computer for DTMAC term, perform Steps 8–10. Perform Steps 8–10 the first time you connect the computer to a DTMAC controller. Fig. 21 Note. If in future the USB port is used to connect the computer to another device, it may be necessary to perform these steps again the next time you connect your computer to a DTMAC controller. 8.

Return to the DTMAC term Select serial port screen and select the COM port identified. Click OK. 12. The DTMAC term main screen appears with a dialog box that says ‘Unable to establish communication with DTMAC’. Disregard the message and click the OK button. Note that the only activity present is the Sent counter at the bottom of the window (Fig. 23). Fig. 22 13. Turn on the DTMAC circuit breaker. Fig. 23 Document # Rev 02 22 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION In the DTMACterm main screen, a message ‘Can’t parse firmware version’ may appear but it can be ignored. After the DTMAC boots up it may not find time and date information yet. Note that the Received counter value indicates the number of messages that the DTMACterm has received from the DTMAC (Fig. 24). Fields under Operating mode indicate when the DTMAC has fully booted in Manual mode (Jog) and the GPS has been read (Fig. 25). Other DTMAC units will get their time information wirelessly from either the GPS unit or from the Coordinator DTMAC which gets the time from an Internet clock. The Motor status error is normal when the DTMAC is in Manual mode (Fig. 25). Fig. 24 Fig. 25 Document # Rev 02 23 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 14. Click the Wireless Network tab in the File Options bar. 15. In the Wireless Network screen, verify that the PAN ID and Node ID values under Local wireless status are the PANID and NODEID decimals, respectively, specified in the project drawings (Fig. 26). 16. Click the Parameters tab. 17. In the Parameters screen, enter (or select) and verify parameter values: 18. Enter (or select) the parameter values indicated in the project drawings in the Position settings and Site parameters fields (Fig. 27). Fig. 26 Fig. 27 Document # Rev 02 24 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION To view the description or details of a field, position your cursor over the field title (Fig. 28). 19. Verify the Site slope, Torque tube slope, and East–West GCR values. Measure the site slope and torque tube slope using a digital inclinometer. Measure the E–W GCR using a tape measure. Compare the measurements with the values in the Site slope, Torque tube slope, and East–West GCR fields. If the difference between the measured value and the entered value is less than 1%, proceed to the next step. If the difference is 1% or greater, contact the DTMAC Monitoring team. Fig. 28 20. When all the parameter values have been entered and verified, click the Update! button. 21. A confirmation dialog box appears. Click OK (Fig. 29). 22. To test the entered data: a. Power down the controller with the DTMAC circuit breaker. b. Close DTMAC term and then re-launch the application after several seconds. Fig. 29 c. Wait 10 seconds before powering the controller back up. d. At the DTMAC term main screen click the Tracker tab and then click the Parameters tab. Verify that the correct values are stored in the Parameters screen. Document # Rev 02 25 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 23. Before closing the controller box, verify that all LEDs (D_S1, D_S2, D_S3, and D_S4) on the DTMAC PCB are not lit. All LEDS should be off; otherwise, the DTMAC will not operate correctly. When lit, the D_S1 LED indicates that the controller is in Stow mode; if flashing at 1Hz, the DTMAC is in Manual. If the D_S2 LED is flashing, it indicates that the motor is not under control. Several problems can cause this condition: the motor failed to track there is no valid time in the DTMAC there is no valid feedback the temperature in the DTMAC enclosure is too high, that is, greater than 70° C The D_S3 and D_S4 LEDs are reserved for future use. However if both LEDs are lit, either there is no software loaded on the Netburner© module or the DTMAC PCB failed. Refer to the DTMAC Troubleshooting Guide for more information. 24. Call or send an email to the DTMAC Monitoring team to complete the commissioning procedure and enable remote control and monitoring for the site. Provide the site name and location, and network configuration data indicated in the project drawings. Note. You are not required to perform this last step onsite unless instructed otherwise by the DTMAC Monitoring team. Document # Rev 02 26 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 2.5.2 Verifying Motor and Controller Wiring 1. With the controller box powered down and the door open, turn the MODE Switch to MANUAL. Power up the controller by turning the circuit breaker on. 2. Turn the DIRECTION Switch to EAST. The modules should begin rotating to the east. If instead the modules rotate west, verify that the correct mount (EAST or WEST) for the installation is selected in the DTMAC Parameters screen (refer to Section 2.4.1, Step 19). If WEST is selected in the Controller mount field and the modules still rotate west, inspect the controller’s power terminal blocks and the motor’s wiring for reversed polarity. Contact SunPower if the wiring for the controller or motor appears incorrect or not according to the electrical wiring diagrams. 3. Turn the DIRECTION Switch back to OFF (the middle position, neither EAST nor WEST). 2.5.3 Verifying Array Flatness A Tracker array is considered “flat” when its modules are at a tilt angle of 0°. 1. Turn the MODE Switch to MANUAL. 2. Turn the DIRECTION Switch to the EAST or WEST positions as necessary to move the modules to a visually horizontal (flat) position. 3. Use an auxiliary digital inclinometer to measure one of the modules at the center of the first row (or place your level E−W, across a fairly even, stable module near the drive strut on the first row), and then use the DIRECTION Switch again to manually move the array, until the auxiliary inclinometer (or level) reads exactly level (or 0° +/− 0.1°). 4. In the DTMAC term screen, click the Parameters tab. Click the Array is flat NOW button. 5. Click the Update! button and then click OK in the confirmation dialog box. Document # Rev 01 27 PROPERTY OF SUNPOWER CORPORATION CONFIDENTIAL INFORMATION 2.5.4 Verifying East and West Limits Warning! During the following procedure, ensure that you closely observe the movement of the modules so that you can use the switches to manually stop the motion if the modules do not stop at 75° or if there is risk of damage. 1. Turn the MODE Switch to MANUAL. 2. Turn the DIRECTION Switch to EAST. 3. Verify that the modules begin rotating to the east. 4. The modules will eventually stop rotating (this will take approximately 22 minutes if the modules were flat when you started jogging east). Use a digital inclinometer to verify that the module directly above the controller inclinometer is at 75° ± 2°. If the angle of the module directly above the controller inclinometer is not 75° ± 2°, you must replace the controller inclinometer. Contact SunPower. 5. Turn the DIRECTION Switch to WEST. 6. Verify that the modules begin rotating to the west. 7. In approximately 45 minutes the modules will stop. Use a digital inclinometer to verify that the module directly above the inclinometer is at 75° ± 2°. If the angle of the module directly above the controller inclinometer is not 75° ± 2°, you must replace the controller inclinometer. Contact SunPower. 8. Return the DIRECTION Switch to OFF (middle position, neither EAST nor WEST). 9. Turn the MODE Switch to AUTO. The controller will automatically begin driving the modules to the optimal position for collecting solar energy. If it’s early morning or late afternoon, do not be alarmed if the tracker starts moving to the nighttime (stow) position. Observe the AUTO mode behavior for ten minutes to ensure that the controller parameters are stable. The Tracker is now operational.
