GP 13 How to Check a Switch
Description
Use this procedure to check the operation of a switch.
NOTE: The wiring diagram in Figure 1 shows an home position switch actuated by the move-
ment of a paddle.
Initial Actions
WARNING
Switch off the electricity to the machine. Refer to GP 14. Disconnect the power cord
from the customer supply while performing tasks that do not need electricity. Electricity
can cause death or injury. Moving parts can cause injury.
Manually check that the switch operates. Ensure that the magnet or other actuator has enough
mechanical movement to operate the switch.
NOTE: The voltages, PJ numbers, pin numbers and PWB names shown are an example only.
Go to the wiring diagram associated with the RAP for the correct information.
Procedure
Enter dC330 code for the switch, actuate and deactuate the switch. The display changes.
YN
Refer to Figure 1. Disconnect T072. +5V is available between pin 1 and pin 2 on the
wiring side of the connector.
YN
Disconnect PJ5. +5V is available at PJ5 between pins 3 and 4 on the HVF PWB.
YN
Perform 01D +5V distribution RAP and 01L 0V Distribution RAP. If both voltage
supplies are good, install a new HVF PWB.
Check the wiring between PJ5 and T072. Repair or install new parts as necessary.
Install a new ejector lower paddle home switch S11-180, PL 11.140.
The switch is operating correctly, check and adjust if necessary, the mechanism that actuates
the switch.
