INSTALLATION AND SERVICE MANUAL
Monoplex Trio

TROUBLE SHOOTING
Trouble shooting the system is aided by the eight diagnostic LED’s on the module. There are seven Green LED’s
connected to the seven outputs channels of the Monoplex Trio. The selected output channel will activate,turn
when the outputs are on The LED for the selected channel will not be illuminated when the channel is deactivated or
when there is a fault condition (over current, over temperature, excessive in-rush current) for the selected output.
The Red LED (labeled Monoplex) is used to diagnose communication status between the remote switch panel(s) and
the module. The LED will flash every time the remote switch panel button is pressed.
In the event, that the LED does not flash
when the switch is pressed, one may plug the switch panel directly into the J1 connector, (MiniFit 2 by 6) as a means
of isolating between the switch panel, wire harness, or the module being bad.
See connector details on page
6 of this manual.
The Monoplex Trio will cease to operate when the battery voltage drops to 9 VDC. This indicates the low voltage
condition and all outputs will turn
in the low voltage condition.

NOTE:
If there is a communication
link fault between a switch panel and the Monoplex Trio module, the Red LED on the module will not illuminate
in response to the switch position on the switch panel being pressed.
In the event that an output channel fault condition exists on the module,(over current, over temperature, loss of
communication, excessive in-rush current), the affected switch panel position LED will flash as prescribed
below:
Over current - Slow Flash rate,1 Hz
Over Temperature -Shutter LEDs on switch panel
Switch Input Fault - Yellow LED fails to illuminate when a switch is pressed
The fault will be communicated to the switch panel to alert the user of the fault condition.
The Monoplex Trio will
automatically shutdown if the inrush surge current is greater than 70 Amps on any channel.
Sometimes, an inductive loads may provide an opportunity to have large current spikes fed back into the module.
The module will protect itself by shutting down and will require the output channel to be engaged again.
