12) Auxiliary inputs: dry or wet selection lights.
13) Auxiliary inputs level: ON = closed or with voltage.
14) Main contacts input sockets: three phases with two chambers each.
15) Main inputs lights: GREEN = main input CLOSED; RED = main input OPEN or pre-insertion
resistor.
16) 5 V DC measurement input connector, for the micro-Ohmmeter circuit.
17) Measurement input sockets, for position transducers or other measurements.
18) Auxiliary 5 V 10 mA supply for the position transducer.
19) High current output sockets for the micro-Ohmmeter.
20) Auxiliary 5 V supply protection fuse, F 63 mA 500 V.
21) CLOSE coil command sockets: one side will be connected to the positive or to the negative of the
DC supply.
22) PARK sockets, unconnected, for the safe positioning of coil commands.
23) OPEN coil command sockets: one side will be connected to the positive or to the negative of the
DC supply. It drives phase 1 if the three phase open option is present.
24) Optional OPEN coil command sockets, for phases 2 and 3: one side will be connected to the
positive or to the negative of the DC supply.
25) Type of test selection pushbutton: as pressed, lights (26) move in a circular way. If unused, the
selection performed via knob (5) and display (6) is shown.
26) Selected test lights. O = Open; C = Close; OC = Open-Close; CO = Close-Open; OCO = Open –
Close – Open; USER = the programmed test sequence.
27) Test START push-button: as pressed, the selected test is started.
28) Test in progress lights: they are ON until the test is finished. When ON, no further START
command is accepted.
29) TRIGGER-IN and TRIGGER-OUT synchronization commands sockets. The Master CBA-1000
TRIG-OUT socket and zero sockets shall be connected to the Slave TRIG-IN and zero sockets.
30) Battery LED: it turns on during battery recharge.
60) Front panel board; code PWA11430.
61) Microprocessor board, code PWA51300.
62) INTE main and auxiliary contacts board, PWA11429.
63) Circuit breaker driver (2 channels) and measurements board, PWA11428.
64) Optional circuit breaker driver (2 channels) and measurements board, PWA11428.
65) Micro-Ohmmeter circuit board, with 14 driving circuits.
80) Rechargeable battery.
81) Auxiliary supply voltages module.
82) Capacitor of the micro-Ohmmeter circuit.
