Battery Charger – BC (Optional)
This option provides a 12Vdc battery and charger kit for the LSE8600 microprocessor controls. It
will automatically fix the transfer switch code to “M” for the relay DC voltage. Please refer to the
transfer switches schematics for reference.
8.15.
Dual Prime Source – DPS (U–to–U) (Optional)
This option allows for selection between two utilities to provide power to the load. A selector
switch is provided to indicate which source is preferred when both are available. The LSE8600
detects this input and constantly monitors for the preferred source.
8.16.
Utility–to–Generator System (Standard)
This option allows for selection between a utility and a standby generator to provide power to the
load. The utility is always the preferred source in this system setup. If, at any time, the utility
power is lost, a generator start signal is sent to the standby generator and the load is transferred
when it is ready to be loaded.
The LSE8600 monitors both sources constantly and will return the load to utility power after a
short time delay. The time delay is to prevent nuisance tripping.
8.17.
Generator–to–Generator System (Optional)
This option allows for selection between two generators to provide power to the load. A selector
switch is provided to indicate which source is preferred. Both “Engine Start” signals must be
connected during ATS Start Up for the LSE8600 to have the ability to call for either generator.
There is a fixed cool down PLC timer set (factory set to 15mins) for the generator connected to
S1. If a different time delay is required, please indicate this at time of ordering, or a field program
update, with a PC, will be required. The timer may be changed for S2 from the front control face
for source S2 generator.
The LSE8600 constantly monitors both S1 and S2 for the preferred source.
8.18.
Multifunction Digital Meter – DM (Optional)
This option provides Load Monitoring CT’s that are wired directly into the LSE8600 controller. The
LSE8600 will leave the factory pre-programmed for the customers system setup. The unit
measures the following (S1 /S2):
1.
Phase to Neutral Voltage (L-N)
