Programming Panel Does Not Power On
When you see this symptom, we need to make sure power is getting to the programming panel from the
computer module.
Possible Cause
Check This
Poor Cable Connections
Verify the DB25 pin connector and Computer Module
Ethernet cables are connected.
Power not getting to programming panel
Verify 24 VDC is making it to the programming panel
enclosure. Remove programming panel rear cover leaving
the two screws at the top for easy removal. Check LEDs
on the inside of the programming panel enclosure as
shown below. If no LEDs are on, then the computer likely
has no power. Make sure the computer module is getting
power.
Motherboard failure
If 24 volts reaches the programming panel enclosure, then
verify the 12 VDC and 5 VDC LEDs are on. If they are on,
there is a failure in the motherboard. Check connections.
If they are good, replace programming panel.
