Cause Possible Solutions
The Run command was not issued again when power
was restored.
• Check the sequence and wiring that has been set up to enter the Run command.

loss.
The relay that is supposed to maintain the Run
command has been switched off.
Check wiring and circuitry for the relay intended to keep the Run command enabled.
