Must be groundedwhen handling PCB.This section provides the operational procedures listed below for theL-828/L-829 constant current regulator (CCR) (4-70 kW/6.6 A or20 A).• CCR control procedures• CCR shutdown procedures• CCR adjustment procedures• S1 cutout Type SCO working positionsThis subsection describes the regulator operations in local and remotecontrols.See Figure 4-1. Refer to Tables 4-1 through 4-3 for output current whenusing local control. The front panel rotary selector switch is used forregulator local control. The rotary switch for the 3-step CCR has fivepositions; the rotary switch for the 5-step has seven positions. The regulatorautomatically maintains the output current within ±1% of the nominal valuefor the brightness position selected.Figure 4-1 Switch (3-Step/5-Step)1. Introduction2.
