V IN (CAT III / 300 V)
The V IN (CAT III / 300 V) inputs can be configured to connect an external source such as a station
battery or an external power supply. In general, the input is not used but if you need to test the behavior
(voltage) of the station battery under real load conditions this option is available.
Note: The coils or the motor can be configured to be supplied from VIN (external source). When
activated, the respective output of CIBANO 500 is supplied from the socket 1 of the VIN section via the
internal command switch. This command switch can also disrupt the current in case of a short circuit.
Input N of the VIN section is for voltage reference measurement only.
A-OUTPUT / INPUT (CAT III / 300 V)
For most tests, the group A is used for measuring timing of auxiliary contacts. The contacts can be “wet”
or “dry”. While dry contacts are free of potential, wet contacts may have a voltage applied to them. The
group A can also be used to record the supply voltage and current of three close coils or three motors
simultaneously by configuring them.
Note: CIBANO 500 has only three command switches. Consequently, three trip or three close coils can
be operated simultaneously but not all six coils at the same time. To record currents for three trip coils
and three close coils separately, connect three close coils to A1 to A3, three trip coils to B1 to B3, and
then perform the Timing (CSM) test.
