NOTE: When this mode is selected the local generator controls should
also be placed in OFF. Failing to do can result in cyclical engine
starting. On loss of Utility supply in this state (loss of control power to
the TSC 800) the engine start contact will drop out after approximately 4
minutes resulting in generator starting and stopping (the cycle will
repeat approximately every 4 minutes after the control power is
removed).
NOTE: On return to normal service the Engine Start output is inhibited
(held up) for approximately 8 – 10 seconds. Requesting another mode
of operation during this time, which requires the engine start contact to
close, will be ignored.
