THEORY OF OPERATION

 

 

The operational discussion presented herein pertains to standard model CSC units.

 

Equipment supplied with options may deviate somewhat from the exact operational

 

description presented, but the basic operating principles are identical for all

 

equipment configurations.

2.1.1Local Control

The CSC control circuits operate from the 120 VAC primary power source and energize the relay coils in the high voltage circuit to supply power to the lighting circuit selected. When switch, remote-off-local, is selected to LOCAL, switches S1 and S2 (S1 through S4) are active. When any of these switches is set to ON, a signal is applied to the timing circuits located on the circuit card assembly. The timing circuit, in turn, supplies power immediately to the coil of the respective double pole relay in the high voltage section. After a brief delay, less than one second, the timing circuit supplies power to the coil of the associated single pole shorting relay in the high voltage section, thus energizing the lighting circuit. (Note: Due to the characteristics of Type L-828 Regulators, the other lighting loads may dim momentarily. This is normal.) To de-energize a lighting circuit, the respective control switch is selected to OFF. This action immediately de-energizes the single pole shorting relay, which places a short across the lighting circuit. After a brief delay, the timing circuit removes power from the coil of the double-pole isolating relay, which opens to isolate the lighting circuit from the regulator. The timing diagram in Figure 2-1 may be helpful in understanding the switching sequence.

De-energized switching (Option -1) is installed on all units. This turns the regulator off prior to switching the circuits and turns the regulator back on after the circuits have been switched. See Sections 3.1.3.2 and 3.1.4 for more detail.

2.1.2Remote Operation

The CSC, when operated remotely, functions exactly the same as when under local control, except that switches S1 and S2 (S1 through S4) are not active. Remote control power is normally derived internal to the CSC. However, external power sources may be used if the proper option is specified.

2.1.3CCR Interlock

An interlock switch is provided for the high voltage section of the CSC. This switch should be connected in series with the control circuit of the CCR to provide for immediate shutdown of the CCR in the event that the dead front cover of the CSC is removed. Normally, however, the CCR or CCRs should be de-energized prior to removal of the dead front cover
