Important:
When the checklist is completed, carefully try to turn the grounding switch to the
grounded position.
b) If the CDP control panel does not display a fault, check that digital output
DO04 of I/O module -A5191 (-A1) is energized.
- DO04 releases the grounding switch and lights the lamp GROUNDING
SWITCH UNLOCKED (–H5152).
- When the LED of DO04 is lit and the control voltage is present at
terminals X24:2 and X24:3 of DO04, DO04 is energized.
□
c) If digital output DO04 of the I/O module is not energized, check the I/O
module -A5191 (-A1).
To do this, check if the auxiliary voltage is present at the supply terminals
of the I/O module.
- X6:1.....24 V (DC)
- X6:2.....0 V
□
d) Check that LED V726 and LED V740 of the I/O module -A5191 are lit.
The LEDs monitor the control voltages of the I/O module (Fig. 11-3).
When the LEDs are lit, the I/O module functions properly.
- LED V726.....24 V (DC)
- LED V740.....5 V (DC)
□
e) If digital output DO04 I/O module -A5191 is energized, check that the
control voltage is present at the terminals of the lamp GROUNDING
SWITCH UNLOCKED.
- If the control voltage is present but the lamp is not lit, the lamp is burnt
out. Replace the lamp.
- If the control voltage is not present, check the wiring of the lamp.
Correct the wiring if necessary.
□
5.
Check that hazardous voltages from the motor cannot be
fed into the drive.
□
If you cannot turn the grounding switch but doors of medium voltage
compartments have to be opened, call the ABB service organization.
