L-828 CCRs LC-Type (4, 7.5, and 10 kW/6.6 A/60 Hz)

Description

 

 

Contactor

In the event of an SCR failure, the contactor provides a means to

 

 

 

 

 

break the current driving the primary of the power transformer T1.

 

 

 

 

 

Under normal conditions, the contactor K1 (see Figure 8-1 in the

 

 

 

 

 

Wiring Schematics section) has no making or breaking current across

 

 

 

 

 

it, since the SCR is off when the contactor is opening and closing.

 

 

 

 

 

This is accomplished by the coil-control circuitry and provides

 

 

 

 

 

increased life for the contactor.

 

 

 

Transformers

Transformer T6 provides 120 Vac remote control source voltage at

 

 

 

 

 

TB2 terminal 8 through fuse F3.

 

 

 

 

 

 

Transformer T3 provides AC voltage to the control PCB. T3 provides

 

 

 

 

 

both 120/60 Vac and 36/18 Vac.
