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.
