Temp Controller Status - HC11 Fault
I have just restarted a GC-MS that was sitting unused for a few months. I can't complete the pump-down procedure and on checking MS Temp Controller Status I get the followng message:
Heater Timeout. Must power cycle to clear.
Heater Voltage too LOW
No Heater Voltage Present.
Quad RTD is Shorted.
Quad RTD not connected.
Source RTD is Shorted.
Source RTD not connected."
Any ideas what might be causing this? I cycled power to no effect. What is the RTD? I can't find a reference to this in the users or installation manuals.
Thanks for any suggestions.
