2000 ECS-12U Controller J85501E-2
5 - 6 Acceptance Testing Issue 3 July 1998
12. Verify that only the NORM LED is lit on the controller.
Reset the restart timer in the controller by pressing switch
SW107, shown on Figure 4-4. This will prevent the
controller from ignoring any HV shutdown that might
occur in the next ten minutes.
13. If the Float/Equalize function is disabled on CP1, this test
is complete. If Float/Equalize is enabled, proceed with
Step 14.
NOTE If the optional Microprocessor Controller Board CP2 is
installed, disconnect it temporarily to complete this test. If
equipped with a CP2 that has not been disconnected, the
controller will default back to the normal float mode when it
sees the EQ HV fault, and the HVSD/R test will not work
properly.
14. Identify the HV shutdown threshold for equalize operation
on DIP switch SW101.
15. Use the front panel switch to put the plant in equalize
mode and verify that the EQ LED lights. This LED should
stay lit through the end of the test. The NORM LED is also
lit at this point.
16. Repeat Steps 2 through 12 with the plant in equalize mode.
17. Return the plant to float mode using the front panel switch
on the controller.
18. Reinstall the CP2.
19. Reset rectifiers to load share mode.
Fuse Alarm Test This test may be performed with or without load on the plant.
1. Insert a paper clip or equivalent as shown in Figure
5-1 to connect the battery lead of the fuse to the alarm lead
of the fuse in F1 (see Figure 2-4). Insulate the part of the
paper clip in contact with the hand. The MNF (Minor Fuse
Alarm) LED on the controller front panel should light, and
the NORM LED should go out. With a multimeter, verify
that the following office alarms are present on the
appropriate terminal blocks on the 113B:
