3.3 LED INDICATORS
The console includes eight LED indicators:
Four LEDs indicate the console operating mode (SHIFTed function, ALARM, MONITOR, or
CONFIGure modes).
Two status LEDs indicate the alarm and control output status of the controller:
The OUTPUT LED, when illuminated steadily, indicates that the output of the
controller is turned on and is allowing current to flow into the heating cable circuit.
The ALARM LED will flash (approximately once per second) when the controller has
detected an alarm condition.
Two additional LEDs are used to indicate external communications activity and are only
used with the C910-485 with the optional RS-485 communications interface.
The "Rx" LED flashes to show that the Controller is receiving information via its
communications port.
The "Tx" LED flashes when the Controller is transmitting information via its
communications port.
