tion, and entails a remedy or troubleshooting procedure.
7.6.1 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 overloa-
ded. Maximum 15 mA or minimum 590 Ω.
A short circuit in a connected potentiometer or incorrect wiring of the potentiometer can cause this condition.

If the warning clears, the problem is with the wiring.
