PROBLEM:
Hose does not heat and the display on the controller shows a flashing error message
“SbEr.”
SOLUTIONS:
1. Check position 9 and 10 on the heater controller for loose wires.
If the wires are tight, move to the next step.
2. Remove the transformer cover and check that the thermocouple wires are secure
to the harness going up to the controller. If there are no loose connections,
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.
PROBLEM:
Heated hose controller shows excessive temperature.
SOLUTIONS:
1. Set the controller set point at least 20F (7C) lower than the temperature shown
on the controller. Briefly turn on the Hose Heater Switch and look for the LED
light on the solid state relay to be lit.
If the light is on, replace the controller.
If the light is off, replace the solid state relay.
PROBLEM:
Hose will heat but does not come up to set temperature.
SOLUTIONS:
1. Check the tap setting on the transformer to ensure that the correct position has
been selected for the length of hose being used. Depending on the machines
incoming voltage, you may have to move the tap setting higher (up one).
CAUTION! Do not exceed the trip value of the transformer hose
breaker.
