7. Servicing the System
The Trident Remote Control Systems is capable of detecting many issues with
both the machine and itself. To help with servicing and repairs, the Trident provides
detailed information via the C220 Controller's status lamp and a special Diag Mode in the
handheld. We will describe these two facilities in this section.
7.1. C220 Controller Status Lamp
The C220/C920 controller contains a single red/green/blue LED which indicates
the operational status of the controller using various colours and blink rates. Note that the
colour mixing may not be ideal when the LED is viewed at certain angles, due to the clear
(undiffused) construction of the LED's lense; nonetheless, the following codes are used:

C220 Controller Status Lamp Indications
Lamp State
Interpretation
Steady Frosty White
The controller is operating properly and waiting for a
radio link from a portable remote controller.
Steady Green
The controller has a radio link from a portable remote
controller.
Steady Turquoise
Some applications feature a colour change of the status
lamp from Steady Green to Steady Turquoise to indicate
that the controller has a radio link from a portable
remote controller and is being commanded to turn on an
output aside from LOOP OUT.
Steady Deep Blue
The controller has been placed into Matching Mode, and
is waiting for another device to match with it. Normal
operation will resume after a device has attempted to
match with the controller, or after one minute if no
device attempts to match.
Quickly Blinking Green
1.
An activated output is overloaded (the connected
load is drawing too much current) or the output is
short-circuited to ground; or
2.
The current-controlled output I/O16 has detected a
solenoid with unusual inductance or resistance.
This is a warning indication and the controller will
continue to operate, with the possible exception of an
output that has excessive load or is shorted to ground.
