Trap status

Status lights

Trap operating correctly

Red and orange lights Off
Green light Flashing

Trap leaking steam

Red light On Green light Flashing

Trap blocked or waterlogged

Orange light On Green light Flashing

Trap cold but free of condensate
(this is a common state during system

Red and Orange lights On

start-up or when the system is shut-down)

Green light Flashing

or sensor wires disconnected.

During normal operation, the green light flashes On every second to show that electrical power
is connected to the R1C and that it is operating correctly.

If the green light is not flashing, there may be a problem with the R1C.

The R1C will show a failure for as long as the fault is present. If the R1C detects a transient fault,
it will show the failure for at least one minute.
