Getting Help
Components within an iWorx® controller, sensor, or power supply cannot be field repaired. If there is a problem with a
unit, follow the steps below before contacting your local TES representative or TES technical service.
1.Make sure controllers, sensors, and power supplies are connected and communicating to desired devices.
2.Record precise hardware setup indicating the following:
Version numbers of application software.
Device and/or firmware version number.
A complete description of difficulties encountered.
Problem
Solution
Controller is not running and Status LED is not
illuminated.
No power to controller. Verify the voltage on the controller’s
power connector (24 VAC).
How do I reset the controller?
The controller can be reset by the LCI, or you can cycle power
to the controller. Refer to the LCI documentation for more infor-
mation on resetting the controller using the LCI.
The 10K thermistor reading is at its maximum or
minimum.
The input is either shorted or open.
Thermistor readings fluctuate rapidly, some-
times by several degrees.
The controller may not be properly grounded. The controller’s
ground (GND) pin (T40) must be connected to earth ground.
Also ensure that the controller’s digital inputs are dry contacts
and that no voltage is being applied or switched to the inputs.
