Troubleshooting
Problem Solution
SmartSeries station faults are
present in the secondary system.
• Verify 12 V dc power is applied to the module.
• Verify CPU PCBA address is set to FF.
• Verify cables are properly inserted into connectors J1, J2, J3.
• Ensure J1 pins of CPU PCBA are correctly inserted into J4 of
lower relay switching PCBA.
SmartSeries stations squeal
when party line 1 or 2 are
accessed.
• Verify connectors J1, J2, J3 are properly inserted. If
disconnected, the page, and party lines 1 and 2 will be
unloaded resulting in oscillation of the SmartSeries handset
amplifier.
Module LEDs do not illuminate
and relays do not switch when
input control is provided.
• Verify 12 V dc (-) is being switched to the PRI
and/or SEC
inputs at JTB4
Module still does not function after
all checks described in this section. Contact GAI-Tronics service for repair or replacement of the
module.
