UNIT VOLTAGE 8AP AP / AP UNIT SIZE ACCESSORY KITS REQUI 09DP DP065-0 GENERAL This book contains instructions for the installation and startup of the Motormaster V electronic low ambient control on 09DP08-0 condenser units. The 09DP065-0 units require two kits per unit. See Appendix A for standard unit ambient temperature limitations. This control varies condenser fan speed based input signal from the Motormaster pressure transducer (MMPT). The control is a variable frequency drive (VFD) and is compatible with the standard motors on these products. The MMPT should be connected to the appropriate liquid line of the unit. When the liquid line pressure drops below the Motormaster controller set point the VFD speed is decreased based on the differential to set point. A fan running at full speed draws too much air across the condenser coil to allow a minimum condensing pressure/ temperature. When these conditions occur, the VFD will slow down and begin to maintain a set point depending on unit type. The Motormaster V low ambient operation kit can be used to extend the system operation down to 0 F ( 8 C). NOTE: The drive is phase insensitive in regard to incoming line voltage. This means that the VFD will operate with any phase sequence of the incoming three-phase power. SAFETY CONSIDERATIONS WARNING Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation. There may be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until work is completed. Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components and equipment location. Only trained, qualified installers and service technicians should install, start up, and service this equipment. When working on air-conditioning equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment. Follow all safety codes. Wear safety glasses and work gloves. Use care in handling equipment. PREINSTALLATION Inspect the contents of the accessory package before installing. File a claim with the shipper if shipping damage is found or contact your Carrier representative if any parts are missing. See Table for accessory kit package contents. INSTALLATION Install Wind Baffles Accessory wind baffles must be field-installed for all units to ensure proper operation at lowambient temperatures with Motormaster V electronic controller. See Table for wind baffle usage. Control Box Modifications CAUTION DO NOT connect incoming AC power to the output terminal T, T, and T. Severe damage to the drive will result. Do not continuously cycle input power to the drive more than once every two minutes. Damage to the drive will result. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Catalog No Printed in U.S.A.

10 SINGLE CIRCUIT APPLICATIONS (09DP065-0) There are two Motormaster drives in the unit. One drive is the lead Motormaster and the other is the follower Motormaster. The previous instructions are for units wired for independent Motormaster control. This application requires modification to the above wiring instructions. In single circuit application MM-A controls the speed of both MM-A and MM-B based on the pressure transducer connected to MM-A. To adjust the wiring for single circuit applications, perform the following procedure:. Remove the wiring to MMPT-B pressure transducer connected to terminals, 5 and 6 on the terminal board of the controller per Fig. 6 and 7.. The accessory is shipped with kit part no. 09DPHLDAA- A00 (Item), which is required for modifying the unit for single circuit application.. Install the wire between MM-A terminal and MM-B terminal. See Fig. 6 and Install the wire with the resistor between MM-A terminal 0 and MM-B terminal 5. See Fig. 6 and 7. START-UP Motormaster V Operation If the controller is wired properly, it is configured for the application and no other adjustments are required. The drive becomes operational when the FR relay contacts close between terminals and of Motormaster terminal board. When the drive is operational it will control the output frequency based on the input of the liquid line pressure transducer or to the input of the lead Motormaster. If the drive does not function properly, the information below and in Tables and 4 can be used to troubleshoot. DRIVE PROGRAMMING CAUTION If input power has not been applied to the drive for a period of time exceeding three years (due to storage, etc.), the electrolytic DC bus capacitors within the drive can change internally, resulting in excessive leakage current. This can result in premature failure of the capacitors if the drive is operated after such a long period of inactivity or storage. In order to reform the capacitors and prepare the drive for operation after a long period of inactivity, apply input power to the drive for 8 hours prior to actually operating the motor. Before attempting to operate the drive or the motor, be sure all procedures pertaining to installation and wiring have been properly followed. If in doubt treat the drive as if it has been without power for an extended period of time. CAUTION It is strongly recommended that the user NOT change any programming without consulting Carrier service personnel. Unit damage may occur from improper programming. To enter password and change program values (see Table and Fig. 0):. Press Mode.. Upper right decimal point blinks.. Display reads 00. To enter the PROGRAM mode to access the parameters, press the Mode button. This will activate the PASSWORD prompt (if the password has not been disabled). The display will read 00 and the upper right-hand decimal point will be blinking. (See Fig. 0.) 4. Use the and buttons to scroll to the password value (the factory default password is ) and press the Mode button. Once the correct password value is entered, the display will read P0, which indicates that the PROGRAM mode has been accessed at the beginning of the parameter menu (P0 is the first parameter). NOTE: If the display flashes Er, the password was incorrect, and the process to enter the password must be repeated. 5. Press Mode to display present parameter number. Upper right decimal point blinks. Use the and buttons to scroll to the desired parameter number. Once the desired parameter number is found, press the Mode button to display the present parameter setting. The upper right-hand decimal point will begin blinking, indicating that the present parameter setting is being displayed, and that it can be changed by using the up and down buttons. Use and to change setting. Press Mode to store new setting. Pressing the Mode will store the new setting and also exit the PROGRAM mode. To change another parameter, press the Mode key again to re-enter the PROGRAM mode (the parameter menu will be accessed at the parameter that was last viewed or changed before exiting). If the Mode key is pressed within two minutes of exiting the PROGRAM mode, the password is not required to access the parameters. After two minutes, the password must be entered in order to access the parameters again. To change password: first enter the current password then change parameter P44 to the desired password. To disable automatic control mode and enter manual speed control mode:. Change P05 to 0- keypad.. Push UP and DOWN arrow key to set manual speed.. Set P05 to mA control to restore 4 to 0 ma control. Fault Codes The drive is programmed to automatically restart after a fault and will attempt to restart three times after a fault (the drive will not restart after CF, cf, GF, F, F-F9, or Fo faults). If all three restart attempts are unsuccessful, the drive will trip into FAULT LOCKOUT (LC), which requires a manual reset. See Table 5.

12 MANUAL RESET If the fault condition has been removed, cycle power to the Motormaster to reset the drive. TROUBLESHOOTING Troubleshooting the Motormaster V control requires a combination of observing system operation and VFD information. The drive provides kinds of troubleshooting modes: a status matrix using the -digit display (P57, P58) and real time monitoring of key inputs and outputs. The collective group is displayed through parameters 50 to 7 and all values are read-only. The key read-only outputs are: P50: FAULT HISTORY This displays the last 8 faults. P5: SOFTWARE VERSION This displays the Software version number. P5: DC BUS VOLTAGE This displays the DC bus voltage in percent of nominal. It is usually rated input voltage x.4. P5: MOTOR VOLTAGE This displays the motor voltage in percent of rated output voltage. AF CF cf CL Table 5 Motormaster Fault Codes P54: LOAD This displays the motor load in percent of the drive's rated output current rating. P55: VDC INPUT This displays the VDC input in percent of maximum input. A display of 00 will indicate full scale, which is 5 v. P56: 4-0 ma INPUT This displays the 4 to 0 ma input in percent of maximum input. A value of 0% = 4 ma and a value of 00% = 0 ma. Liquid Line Pressure Set Point Adjustment Adjusting the set point may be necessary to avoid interaction with other head pressure control devices. If adjustment is necessary, use the set point parameter found in P4 for R-40A or P5 for R-4a. A lower value will result in a lower liquid line set point. As an example for R-40A, decreasing P4 from 4 to will decrease the liquid line pressure by approximately 5 psig. As an example for R-4a, decreasing P5 from.6 to.6 will decrease the liquid line pressure by approximately 5 psig. It is recommended to adjust R-40A units by and R-4a units by 0.5. FAULT CODE DESCRIPTION SOLUTION High Temperature Fault: Ambient temperature is too high; Cooling Check cooling fan operation fan has failed (if equipped). Control Fault: A blank EPM, or an EPM with corrupted data has been installed. Incompatibility Fault: An EPM with an incompatible parameter version has been installed. CURRENT LIMIT: The output current has exceeded the CURRENT LIMIT setting (Parameter 5) and the drive is reducing the output frequency to reduce the output current. If the drive remains in CUR- RENT LIMIT too long, it can trip into a CURRENT OVERLOAD fault (PF). Perform a factory reset using Parameter 48 PROGRAM SELECTION. Either remove the EPM or perform a factory reset (Parameter 48) to change the parameter version of the EPM to match the parameter version of the drive. Check for loose electrical connections. Check for faulty condenser fan motor. Check Parameter P5 from Table 4 is set correctly. GF Data Fault: User data and OEM defaults in the EPM are corrupted. Restore factory defaults P48, see section above. If that does not work, replace EPM. HF High DC Bus Voltage Fault: Line voltage is too high; Deceleration rate is too fast; Overhauling load. Check line voltage set P0 appropriately JF Serial Fault: The watchdog timer has timed out, indicating that the serial link has been lost. Check serial connection (computer) Check settings for PXX. Check settings in communication software to match PXX. LF Low DC Bus Voltage Fault: Line voltage is too low. Check line voltage set P0 appropriately OF Output Transistor Fault: Phase to phase or phase to ground short circuit on the output; Failed output transistor; Boost settings are too high; Acceleration rate is too fast. Reduce boost or increase acceleration values. If unsuccessful, replace drive. Check for incorrect wiring T, T, T. PF SF Current Overload Fault: VFD is undersized for the application; Mechanical problem with the driven equipment. Single-phase Fault: Single-phase input power has been applied to a three-phase drive. EPM Fault: The EPM is missing or damaged. F F-F9, Fo Internal Faults: The control board has sensed a problem Consult factory Drive display = 60.0 even though it is Feedback signal is above set point cold outside and it should be running slower Drive display = --- even though drive should be running Drive display = 8.0 even though fan should be running faster VFD flashes 57 and LCS LEGEND EPM Electronic Programming Module LCS Loss of Control Signal OEM Original Equipment Manufacturer VFD Variable Frequency Drive Start jumper is missing Feedback signal is below set point and fan is at minimum speed Feedback or speed signal lost. Drive will operate at 57 Hz until reset or loss of start command. Resetting requires cycling start command (or power). Check line voltage set P0 appropriately Check for dirty coils Check for motor bearing failure Check input power phasing Check for proper set point Check liquid line pressure Replace start jumper. See section above Check for proper set point Check liquid line pressure In stand alone mode: Check transducer wiring and feedback voltage. Feedback voltage displayed on P69. Pin 6 should be 5 v output. Pin 5 (feedback) should be somewhere between 0 and 5 v.
