Rockwell Automation 1771-OND INSTL.INSTR AC (24V) OUTPT.MOD - Manual (Page 10)

AC (24V) Output Module 10
Publication 1771Ć5.41 - May 1996
Modules with External Fuses Only
1. Turn off all power to the I/O chassis and all output device power
to the field wiring arm.
2. Pivot the wiring arm away from the module.
3. Use a continuity checker (meter in low ohms setting) to check
fuses for an open (high resistance) reading.
4. Note if fuse is open and trace the output wiring back to the output
device.
5. Check the remaining fuses (refer to step 3).
6. After all faulty fuses are replaced and any wiring problems
solved, reposition the wiring arm on the module.
7. Turn off all outputs to the module.
8. Turn on power to the I/O chassis.
9. Check that the red status indicators on the front of the module are
off (no outputs on). Make sure the red fuse blown indicator is off.
10.Turn on output device power to the wiring arm.
11. Start with bit 00 and turn on individual outputs one at a time.
Turn off last output before turning on the next output.
12.If the red fuse blown indicator lights, note which output is faulty
and trace the output wiring to the faulty device.
After correcting the fault problem, return to step 1 and begin again.
If you cannot locate a faulty output, return to step 8 and turn on 2 or
more outputs at the same time. Total output current should not
exceed 2A per output, or 8A per module.
