All Tanks Read LOW:
•
Check to make sure the element breaker is ON (element switch is to the left). Tanks will read low until the
temperature in them reaches 175° F. Please allow 20
- 30 minutes to heat up initially.
An Individual Tank Reads LOW:
•
Check the connections at the temp probe.
•
Check the thermal overload switch. If the switch has overheated, the center button will pop out. Depress
the button if so. Check again for heating. Check that temp stabilizes at set point.
•
Check for continuity between the heating element posts and ground (metal of tank or frame). If continui-
ty exists, the element has failed. Check for proper resistance across element posts. If resistance is out of
spec, the element has failed.
WARNING : Disconnect power to the machine when testing the elements.
•
Test the element relay. If relay is receiving a low voltage signal from the board but not lighting up (red
light), then the relay has failed.
An Individual Tank Reads Above the Set Point:
•
Check the connections to the temp probe.
•
Check for continuity between the heating element posts and ground (metal of tank or frame). If continui-
ty exists, the element has failed. Check for proper resistance across element posts. If resistance is out of
spec, the element has failed.
WARNING : Disconnect power to the machine when testing the elements.
•
Test the element relay. If relay is not receiving a low voltage signal from the board but is outputting high
voltage, the relay has failed.
Handheld Controller Display is Blank:
•
If the red power switch is in the ON position and is NOT lit, there is a lack of power to the machine. Check
the wall plug and circuit breaker.
•
If the red power switch is in the ON position and is lit, check that the lid of the electronics box is tightly
secured to the box. There is a safety interlock switch inside the box which interrupts power to the elec-
tronics when the lid of the electronics box is loose or removed.
•
Check the connectors on both ends of the handheld controller cord and ensure they are fully seated in
both the display board and the main electronics board.
Shot Timers are Blank; Machine is Powered:
•
Inspect the ribbon cable. Ensure all connectors are properly seated in the shot timer boards and in the
main electronics board. Ensure there is no damage to the cable.
