1. Construction
The Transfer Switches covered in this manual use molded case switches and/or circuit breakers
to accomplish the transfer of two separate power sources to a single load.
These molded case circuit breaker(s) and/or switch/switches, (molded case units), are interlocked
via electrical and mechanical control systems.
The LSE8600 Controller combined with the auxiliary contact switch located in the molded case
unit encompasses the electrical interlock system.
The physical "Plunger Style" interlock installed between the two molded case units
encompasses the mechanical interlock system. The interlock is located on the rear of the
base plate and is a fulcrum and lever device, which positively prevents both molded case
switches or circuit breakers from being in the ON position simultaneously.
The two control systems provide a redundant interlocking scheme which provides a "Fail-Safe"
design. Note: This mechanical interlock is not provided on units equipped with the Closed
Transition Option.
The gear motors are operated at 120Vac, supplied by the unit. The gear reduction unit is
permanently lubricated so that it requires no maintenance.
All styles of transfer switches are provided with an insulated operating handle to enable personnel
to manually operate the transfer switch in the event of an emergency. The handle is permanently
mounted and readily accessible and allows the operator to manually operate the transfer switch
under load.
All interface relays are of the enclosed industrial type to ensure long life and minimum
maintenance. They are rated for continuous duty to eliminate overheating of coils.
The LSE8600 controller will provide adequate control of the Automatic Transfer Switch (ATS).
These controllers offer programmable timers. Including the plant exerciser, and these values are
stored in non-volatile memory.

2. Description of Operation
The following are general descriptions of operation applying to the different styles of Transfer
Switches. Certain accessory additions may modify the sequence of operations as required to
suit specific applications.
2.1. Single Motor Operator
The Single Motor ATS utilizes a single motor to operate both the normal and emergency molded
case units. Normally, the transfer switch operates on the preferred power source with the Normal
molded case unit in the closed position and the Emergency molded case unit in the open position.
(Refer to Individual Unit Wiring Diagrams Included with the Transfer Switch.)
All phases of the preferred power source, S1 (typical: Utility), are continuously monitored by the
voltage sensing inputs of the LSE8600 Controller. These undervoltage settings are preset to 90%
pick-up and 80% drop-out of the nominal voltage. If different settings are required, please contact
Lake Shore Electric for assistance in changing these settings. In the event of a drop in any phase
of the preferred voltage below the dropout set point, the LSE8600 Controller will follow these
steps:
1. The S1 light on the LSE8600 controller will turn off and the display will indicate a warning
under the "Alarm" screen menu.
2. The "S2 Start Delay" will time for the Factory Default setting of 3 seconds. This would be
the standard "Engine Generator Start Delay" time to avoid nuisance transfers.
3. Then the "S1 Return Delay" will time for the Factory Default setting of 3 seconds. This
would be the standard "Time Delay to Emergency" to avoid premature loading of the
generator.
4. The "NS" molded case unit will open to remove the load from S1 power source, and the
“ES” molded case unit will close at the same time to connect the load to S2 power source.
NOTE: If overvoltage sensing is used, factory default settings would be 120% drop-out and 115%
pick-up of nominal voltage.
The preceding sequence of operation describes the operation of a basic single motor operated,
Automatic Transfer Switch (ATS). Lake Shore Electric offers a wide variety of accessory
equipment to meet customer specifications. Please refer to the schematic diagram provided with
your Lake Shore ATS for specific controls provided.

Page 10
2.2. Dual Motor Operator
The Dual Motor Automatic Transfer Switch (ATS) operates in much the same way as described
in section 2.1 Single Motor Operator with the exception that each molded case unit has its own
motor operator. This allows the load to be disconnected from both the S1 and S2 power sources,
offering the load a "Neutral / Off" position. When the LSE8600 sends the signal to transfer, one
motor operator disconnects its source, which transfers the switch to the open position temporarily.
Then, the LSE8600 sends the signal to the opposite motor operator, connecting the load to its
source.
All phases of the preferred power source, S1 (typical: Utility), are continuously monitored by the
voltage sensing inputs of the LSE8600 Controller. These undervoltage settings are preset to 90%
pick-up and 80% drop-out of the nominal voltage. If different settings are required, please contact
Lake Shore Electric for assistance in changing these settings. In the event of a drop in any phase
of the preferred voltage below the dropout set point, the LSE8600 Controller will follow these
steps:
1. The S1 light on the LSE8600 controller will turn off and the display will indicate a warning
under the "Alarm" screen menu.
2. The "S2 Start Delay" will time for the Factory Default setting of 3 seconds. This would be
the standard "Engine Generator Start Delay" time to avoid nuisance transfers.
3. Then the "S1 Return Delay" will time for the Factory Default setting of 3 seconds. This
would be the standard "Time Delay to Emergency" to avoid premature loading of the
generator.
4. The "NS" molded case unit will then be opened to remove the load from S1 source power.
5. The "Non-Sync Transfer Timer" will time for the Factory Default setting of 0 seconds.
However, there is a prebuilt in timer of 3 seconds that cannot be changed below that setting
for this controller. However, the delay may be increased by changing the Factory Default
from 0 seconds to the desired time delay.
6. The "ES" molded case unit will then be closed to connect the load to S2 source power.
NOTE: If overvoltage sensing is used, factory default settings would be 120% drop-out and 115%
pick-up of nominal voltage.
The Dual Motor ATS is used EXCLUSIVELY FOR SERVICE ENTRANCE (SE) RATED
TRANSFER SWITCHES because the dual motor design allows for the necessary condition of
having both switches in the "OFF" position so that the load is isolated and disconnected from both
sources.
The Dual Motor ATS is also used EXCLUSIVELY FOR CLOSED TRANSITION TRANSFER (CTT)
SWITCHES because the dual motor design allows for the necessary condition of having both
switches in the "ON" position so that the load is momentarily connected to both sources when
they are synchronized providing a "make before break" transfer.
(Refer to Individual Unit Wiring Diagrams Included with the Transfer Switch.)
