1:1:2 Operation:
The OPT2600 includes the suitable sensing circuitry for automatic transfer of an
electrical load to a stand-by power supply in the event of a drop or loss of voltage of any
or all phases of the normal power supply. Upon the restoration of the normal supply, the
electrical load is automatically re-transferred to the normal power supply. The normally
required time delay functions are all included in the Timer Module package.
The transfer motor utilizes power from the source to which the electrical load is being
transferred. The mechanism provides an optional mechanical interlock to prevent both
switches from being closed at the same time. The OPT2600 also incorporates the basic
actuating motor control switches, terminal blocks, and voltage sensing connection points
for Utility Line sensing. Provision is also made for manual transfer of the power sources
if necessary. The OPT2600 mechanism is a lever-operated device controlled by a 120
volt, 60 HZ 3 amps thermally protected unidirectional gear-motor.
The transfer motor drives a crank that in turn operates a lever arm. The lever, in turn,
operates the two switch handles by means of guided roller assemblies. The roller
assemblies are independently adjusted by either hexagon nuts or rollers. The travel
position of the lever arm is detected by two micro switches, which in turn disconnect
power to the transfer motor, when appropriate.
The dipswitch located on the TSC3A is used to set the load / no load setting (refer to
TSC3A user manual). When switch location #3 is on, the system is configured for a load
condition. When switch location #3 is off, the unit is configured for a no load condition.
This setting applies to the remote test switch and engine exercise option only. This setting
allows for exercising the transfer switch under a loaded or a no load condition.
When testing or exercising the transfer switch under a load condition the switch will
transfer to generator emergency power. When testing or exercising the transfer switch
under a no load condition the switch will not transfer and stay in the normal power
position. Please refer to the TSC3A user manual for a more advanced and detailed
outlook on the TSC3A and its functionality.
