DESCRIPTION
The nVent RAYCHEM ECW-GF-DP is a remote display panel only
for the RAYCHEM ECW-GF electronic controller. The ECW-GF-DP
allows remote monitoring of the heating cable system operation.
The display has LED indicators which signal communication loss
to the controller, high/low temperature alarm, and temperature
sensor failure. The display also has buttons to test and reset the
ground-fault sensor. The display may be located up to 328 feet
(100 m) from the ECW-GF controller.
The ECW-GF-DP remote display panel must be installed in
conjunction with the ECW-GF controller. Refer to the ECW-GF
installation instructions (H58339) for further details.
For technical support, call nVent at (800) 545-6258.

controller is powered.
Communication Error
If the Green LED is blinking verify that the wiring
to the display and controller are correct.
Ground-Fault Error
If the Red LED is blinking, the system has a
ground-fault error. Check the ECW-GF controller
for the error code on the display. Press the Reset
button once the ground-fault error has been
corrected.
Ground-Fault Test
To test the ground-fault circuitry, press and hold
the Test button, if the circuit passes, the Amber
LED will blink rapidly.
System Alarm
If the Red and Amber LEDs are blinking
alternately, the heating cable system is in
alarm. (Temperature sensor failure or high/low
temperature alarm.) Check the ECW-GF controller
for the displayed error.
