Common Support Questions


This would indicate that you have enabled the Low Temperature Alarm and that the current temperature the sensor is sensing is below the alarm setpoint. You can change the set point, wait for the heaters to warm the sensor, or disable the alarm.

The GPT-230 displays a number of alarms, beside the ground fault it will also alarm for low current. If you have disconnected the load to trouble shoot a possible ground fault in the heater cable, then you probably have a Low Current Alarm and a very low default ground fault current reading.

You can tell the difference by looking closely at the display, it will tell you what the alarm is for. If you want to clear the low current alarm so you can test the controller then go into the configuration menu and disable the Low Current Alarm. You will need to do this for each channel.

Remember to re-enable the Low Current Alarms when you are done testing and ready to put the unit back into service.

Yes, you can use a 3-wire RTD Sensor: Platinum, Alpha = 0.00385, ITS–90,100 ohms. Once it is installed you will need to configure the controller for it by navigating to the sensor type screen and changing it to RTD. The GPT-230 will allow you to use a different sensor on each channel or you can use one sensor for both channels. It is simply a matter of how you wish to configure it.
