5.1.2. OVER CURRENT TRIP (TSC 80/TSC 800 CONTROLLERS)
Should the utility power switching device trip open due to an over current condition,
TSC 80 or TSC 800 transfer controller will initiate an engine start signal and will
permit transfer of the load to the generator supply. The utility source will be locked
out and the load will remain on the generator supply until the TSC 80/TSC 800 alarm
signal is manually reset.
Refer to the TSC 80 & TSC 800 Instruction Manuals for further details on Transfer
Fail operation.
Should the generator power switching device trip open due to an over current
condition, TSC 80/TSC 800 transfer controller will initiate transfer of the load to the
utility supply. The generator source will be locked out and the load will remain on the
utility supply until the TSC 80/TSC 800 alarm signal is manually reset.
5.1.3. OVER CURRENT TRIP (MEC 2/MEC 20/MEC 310 CONTROLLERS)
Should the utility power switching device trip open due to an overcurrent condition,
the generator will not automatically start and transfer on load. The generator must be
started and transferred on load manually.
Should the generator power switching device trip open due to an overcurrent
condition, the generator will shutdown and the load will automatically return to the
utility supply if its voltage is normal. Note: for automatic transfer to utility, the transfer
switch must be factory ordered with a "gen breaker tripped" auxiliary contact inside
the generator power switching device and must be wired to the gen set controllers
shutdown alarm circuits.
Refer to the Gen Set controller instruction manual for further details on manual
operation or shutdown-reset operation.

TEST MODES

The transfer switch may be tested utilizing the controller pushbuttons or optional test switch.
A simulated utility power failure condition will be activated when the test mode is selected.
The transfer switch will operate as per a normal utility power fail condition.
The transfer switch will remain on generator supply until the test mode is terminated. It will
then immediately transfer back to the utility supply and then continue to operate the
