Description
TDEC
Time Delay Engine Cool:
This delay allows the engine to continue running after the transfer switch returns to the normal (utility) position. When
the control board recognizes that the transfer switch is in the normal (utility) position after an emergency generator) to normal (utility) transfer, the
generator will continue to run under a no-load condition until the engine cool time delay has expired.
TDES
Time Delay Engine Start:
This delay prevents unnecessary engine starts. When the control board determines a utility failure, it will wait for the
Engine start time delay to expire before trying to start the generator.
TDNE
Time Delay Normal (Utility) to Emergency (Generator):
This delay allows the generator to stabilize before any load is transferred. This normal
(utility) to emergency (generator) time delay allows the generator to be fully running before supplying power to a load.
TDEN
Time Delay Emergency (Generator) to Normal (Utility):
This delay allows the utility source to be monitored for stability. This emergency
(generator) to normal (utility) time delay allows the utility to be monitored for the set amount of time to confirm that it is fully restored and stable.
TDNP
Time Delay Neutral Position:
This delay allows the transfer switch to temporarily stop between normal (utility) to emergency (generator) and
emergency (generator) to normal (utility) transfers. The temporary stop allows controlled isolation between the both normal (utility) and emergency
(generator) sources. (Not available on the 400A switch.)
