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.
