Troubleshooting
Problem Solution
Module is damaged. Do not attempt to repair the module.
Contact GAI-Tronics service for repair or replacement of the
module in accordance with the information provided on this page.
Voltage is applied to both inputs,
but voltage is not present at the
output terminals. Verify plug-in connectors at JTB1, JTB2 and JTB3 are properly
inserted.
All connections and connectors are
properly made, but still no output
voltage. Verify wiring at each connector has proper polarity.
Relay status contact markings are
incorrect when module is not
powered. The relay status contact markings are based on the module being
actively powered (i.e., in an energized state).
After performing all wiring checks,
trouble-shooting, etc. as described
in this section, the module still does
not function properly. Contact GAI-Tronics service for repair or replacement of the
module in accordance with the information provided on this page.
