1. 6 FANUC SUPPLY SERIES SIX PROGRAMMABLE CONTROLLERS 123 VDC INPUT CPU POWER i GFK 0065 Source Voltage 100 to 150 V dc Output Voltage 5 12 12 V dc GENERAL DESCRIPTION The 125 V dc Input CPU Power Supply Module used in the Central Processor Unit CPU is available to be used with a power source from 100 to 150 V dc The features and benefits of this summarized in Table 1 The 125 V dc Input CPU Power Supply Module provides regulated 12 12 and 5 dc voltages to the rack backplane The input or source voltage is applied to terminals on the front panel then routed through a switch and fuse to a switching power supply For a given load the input power drain remains essentially constant The power supply is protected against polarity reversal of the dc Input The module provides electromechanical relay contacts for connection to user indicators or any device to be activated during an alarm condition The module also module are provides a voltage regulator for an opt ional auxiliary battery that provides battery back up of Complementary Metal Oxide Semiconductor CMOS memory contained in the processor rack A Keyswitch mounted on the front panel is used to select either the RUN or the STOP mode for the processor a second Keyswitch allows the user to protect the contents of the processor memories by placing them in a READ ONLY mode The same key operates both Keyswitches Refer to T2. Figure 2 Be sure to connect the 18 pin molex connector P1 to the power supply Attach the wire clamp on the upper stud of the power supply frame or if there is a clamp already there wrap the wires in it 11 12 13 14 15 Slide the power supply into the rack being careful not to damage the wires When the power supply is al the way in turn the thumbscrews clockwise until they lock in Remove the plastic cover on the lower portion of the power supply and attach the DC wires as well as the battery and alarm wires as they were on the original supply Refer to Step 6 and Figure 3 Replace the plastic cover Verify that the DC input lines are of the correct polarity before applying power An inadvertant reversal of input polarity will cause the supply to draw excessive currents and may blow the internal fuse 2A slo blow which must then be replaced before proper operation can be resumed Restore system power Turn on the CPU unit Check to see if the POWER light is on If it is turn on the rest of the system and resume normal operation If the POWER light does not come on the power supply may be bad source voltage may not be turned on or there may be other problems within the rack Please call your local authorized GE Fanuc Automation Distributor or Sales off ice for assistance GFK 0065 125 V dc Input CPU DPU Power Supply Module 5 WIRES FROM THE BACK PLANE WILL BE MARKED TERRAS P STB
