July, 1989 I/O Rack Power Supplies General Description The I/O Rack Power Supplies, which provide power for Series Six I/O modules, are available in two versions: Standard and High Capacity. The Standard I/O power supply is integral to the Standard I/O Rack; likewise, the High Capacity I/O power supply is integral to the High Capacity I/O Rack. The features and benefits of these power supplies are summarized in Table 1. The Standard I/O power supply provides a regulated +5 Vdc voltage to the I/O Rack backplane at a maximum current rating of 6.1 amps. The High Capacity supply provides regulated +5V, +12V and -12 Vdc to the I/O Rack backplane at a maximum current rating of 16.5 amps (+5V only). This power supply provides power for high-current I/O module configurations and remote I/O applications. The I/O Rack Power Supplies can operate from input voltages ranging from 95V -130 vac, or from 19OV - 260 Vac, at frequencies of 47 to 63 Hz. The input power is applied to a terminal block on the front panel, routed through a circuit breaker and a line filter, then rectified and regulated by a switching power supply. On the front panel of the I/O Rack power supply is a DC output ON/OFF switch called, LOGIC POWER; visible through a lens is a Light-Emitting Diode (LED) that lights when the LOGIC POWER switch is in the ON position; and underneath a black, plastic cover is an AC-input terminal block. The I/O Rack Power Supplies also generate a power-fail signal (PSOK) which is used for system- level error indications. Refer to Table 4 for I/O Rack Power Supply specifications. Table 1.

User Items (Part 2 of 2) Verify that the I/O Power Supply to be installed can accommodate the estimated load. Total the current units as indicated in Table 2, per the I/O modules to be utilized. If installing a Standard Power Supply, the input voltage mode must be established by jumper on the front panel terminal block. Figure 2 indicates the two input modes selectable, 115V AC or 230V AC, and the corresponding positions of the jumper strap. The High Capacity power supply input mode cannot be altered from that established at the GE factory. These steps defme the procedures to be followed when a power supply is to be replaced on a Series Six I/O Rack. The tools needed are a regular screwdriver, Phillips screwdriver, and a 5/16 wrench or nut driver. 1. 2. 3. 4. 5. 6, Stop the system by switching the top key on the CPU to STOP . Switch off all units in the system, including the user s power supplies. Remove all power from the system, preferably at the source (i.e. throw the main circuit breaker for the system). Locate the I/O rack power supply to be changed. The power supply is in the far right side of the I/O rack. Remove the plastic cover on the lower portion of the power supply and, using a volt-meter, make sure there is no AC power present. Take note of the location and color of the AC wires and then remove them. 7. 8 . 9. 10. 11. At the top and bottom of the power supply, there are l/4-turn thumbscrews. To loosen, turn the thumbscrews approximately l/4 turn counterclockwise. Grasp the thumbscrews and gently pull outward. Be careful while removing the power supply of the wires inside; pull the power supply completely out. Locate the wires that extend from the back of the I/O rack to the terminal on the power supply. These wires should be labeled or stamped with their location; the circuit boards have wire locations stamped on them also, (Refer to Table 3.) Remove these wires. There is also a plastic wire clamp holding these wires in place. Detach this from the frame if there is not a similar item on the replacement power supply, or cut the clamp if there is one on the new supply. On the High Capacity rack, remove the 18-pin (Pl) molex connector that is on the narrow board in the front part of the power supply. The power supply should now be completely detached from the I/O rack. Take the replacement power supply and attach the wires as shown in Table 3. On the High Capacity rack be sure to connect the 18-pin molex connector (Pl) 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. Slide the power supply into the rack, being careful of the wires. When the power supply is all the way in, turn the thumbscrews clockwise l/4 turn, or until they lock in. 4 I/O Rack Power Supplies GEK-83511B 12. Remove the plastic cover on the lower portion of the power supply and attach the AC wires as they were on the original supply (Refer to Step 6). Replace the plastic cover. 13. Restore system power. Turn on the I/O Rack. Check to see if the \"Power\" light is on. If it is, turn on the rest of the system and resume normal operation. 14. If it does not come on, the power supply is bad or there are other problems within the I/O Rack. When this occurs, you can call the Programmable Control Service Center EMERGENCY SERVICE NUMBER (804) 978-5747 for assistance. 15. Repack the power supply removed from the I/O Rack and return to Industrial Control Department, General Electric Company for proper credit. Table 2.
