1Overload Supplementary Protecotr CB1
Supplementary protector CB1 pro- tects the 115 volts ac windings of control transformer T3 from over- load. If CB1 opens, the 115 volts ac duplex receptacle RC2 would not work. Manually reset CB1.
2Module Supplementary Protectors CB11 Through CB81
The control circuitry in each of the eight modules is protected from overload by a supplementary pro- tector CBX1 (“X” represents the number of the applicable module, 1−8). If a module supplementary protector opens, output from the affected module would drop to mini- mum and can not be regulated. Manually reset the affected protector.
