Page 8: Status/Alarm Indicators
A load sharing circuit is provided on the terminal board. When connected, two (2) or more La Marche TPS units are forced to share the load equally within +/- 5%. Individual unit outputs must be greater than 10% of rated output. -
Page 9: Current Walk In
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION CURRENT WALK IN Output current will gradually increase after the rectifier is initially turned on reducing current surges. EMERGENCY RESTORATION This rectifier may be connected to a battery which is heavily discharged and recharge it without clearing any protective devices while powering d.c. -
Page 10: Installation Information
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION INSTALLATION INFORMATION MINIMUM WIRE SIZES Table 2 lists the a.c. input and the d.c. output minimum wire size requirements. At distances exceeding 10 feet, the d.c. wire size should be chosen to keep the voltage difference between the units d.c. -
Page 11: Field Ground Terminal
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION FIELD GROUND TERMINAL This terminal should be connected to an earth ground. The size of the conductor is based on National Electric Code Table 250-95 for copper wire at 75 degrees C. (See Table #2 for recommended wire sizes.) -
Page 12: Input
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION A.C. INPUT Make sure that a.c. power is off at the main a.c. breaker box before installation begins. Make sure that the input source is the same voltage and frequency as that which is marked on the nameplate of the rectifier. -
Page 13: Load Sharing
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION LOAD SHARING When the load sharing terminal (LS) on the (TS) terminal strip is connected, multiple units are forced to share the load current within +/- 5%. Individual unit outputs must be greater than 10% of the rated current output. -
Page 14: Equalize Adjustment
11.0 11.1 CIRCUIT OPERATION The Model TPS rectifier circuit design is a controlled ferroresonant converter. The power transformer PT provides a.c. to d.c. isolation, voltage step down, and inherent magnetic current limit. The secondary circuit of PT & capacitor C2 form a resonant tank circuit. The secondary voltage of the transformer is controlled by the shunt control which consists of choke L1 and the a.c. -
Page 15: Troubleshooting
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION TROUBLESHOOTING 12.0 Troubleshooting should be performed only by trained service personnel or experienced electricians. CAUTION: Hazardous a.c. and d.c. voltages are present within the rectifier cabinet. Equipment: The only equipment required is a multimeter for voltage or resistance readings and analog ohmmeter 12.1 GENERAL INSPECTION... -
Page 16: Symptoms & Causes
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION 12.3 SYMPTOMS & CAUSES 12.3.1 A.C. Breaker trips. Possible Cause: 1. Wrong a.c. input voltage. 2. The a.c. input taps on power transformer set incorrectly. 3. (See schematic wiring diagram) 4. An a.c. to d.c. short or a.c. or d.c. short to ground (see ground short circuit test). -
Page 17: Charger Operates But Output Voltage/Current Is Low
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION 12.3.3 Charger operates but output voltage/current is low. Possible Cause: 1. Float/Equalize voltage potentiometers not set correctly (see float/equalize adjustment procedure for proper voltage setting). 2. Check power diodes or diode modules and triac (see diode and triac troubleshooting procedure). -
Page 18: Troubleshooting And Replacing The Triac
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION 4. Check the input terminals to ground and check the output terminals ground. If the meter indicates full scale deflection, a wire is touching a metal part of the rectifier. Look for wires that are near any metal part and inspect for possible breakdown caused by shipping. -
Page 19: Checking Capacitors
MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION 12.6 CHECKING CAPACITORS When checking capacitors be sure all a.c. power is turned off and battery is disconnected from unit. Check capacitors with d.c. voltmeter to see that d.c. voltage is at near -0- volts, then short circuit capacitor. -
Page 20: Manufacturer's Warranty
Should minor adjustments be required, the local La Marche Sales Office should be contacted to provide this service. All sales are final. Only standard La Marche units will be considered for return. A 25% restocking fee is charged when return is factory authorized. Special units are not returnable. - Page 21 MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION INSERT PICTURE: PIC-TPS-PAGE1 21 OF 20 CPN 40615...
