8.4.2 WARNING 1, 10 Volts Low
Cause
The control card voltage is less than 10 V from terminal 50. Remove some of the load from terminal 50, as the 10 V supply is
overloaded. Maximum 15 mA or minimum 590 Ω.
A short circuit in a connected potentiometer or incorrect wiring of the potentiometer can cause this condition.
Troubleshooting
• Remove the wiring from terminal 50. If the warning clears, the problem is with the wiring. If the warning does not clear, replace the
control card.
