TROUBLESHOOTING
PROBLEM
Hose does not heat and the display on the controller shows a flashing error message:
“EEEE” on the Auber controller, “SbEr” on the Eaton controller, or “S.ERR” on the Omron
controller.
SOLUTIONS
1. Check the thermocouple terminals (TC+ and TC-) on the heater controller for loose
wires and improper connections. There should be a purple wire connected to the TC+
Terminal and a red wire connected to the TC- Terminal. See Table 1 below for
terminal connections for each type of controller.

TC+ Terminal (Purple Wire)
Terminal 7
Terminal 9
Terminal 12
TC- Terminal (Red Wire)
Terminal 6
Terminal 10
Terminal 11
If connections are secure, move to the next step.
2. Remove the transformer cover and ensure the thermocouple wires are secure to the
harness going up to the controller.
If connections are secure, move to the next step.
3. Disconnect the wire from the TSU and connect it directly to the thermocouple harness
coming out of the hose transformer.
If the controller still shows the error code, replace the hose thermocouple.
If the error code goes away and temperature is now shown on the display of the
controller, then all the TSU harnesses from the TSU to the transformer need to be
checked for loose connectors or one or more of the harnesses are defective.
