Cause : 10 Volts low comes when the control card voltage is below 10 V from terminal 50. Remove some of the load from terminal 50, as the 10 V supply is overloaded. Max. 15 mA or minimum 590 Ω.
- This condition can be caused by a short in a connected potentiometer or improper wiring of the potentiometer.
- Remove the wiring from terminal 50.
- If the warning clears, the problem is with the customer wiring.
- If the warning does not clear, replace the control card.
