282 OMICRON
19 Transducers
Note: Based on their robust design, digital motion sensors delivered by OMICRON need neither a
periodic accuracy validation nor calibration.
This section describes how to use the transducers for measuring the circuit breaker’s contact travel with
CIBANO 500 and the related issues. The emphasis is on the attachment of the transducers to the circuit
breaker.
Motion measurements are a well proven and widely used method to assess the mechanical linkage of a
circuit breaker. To benefit from this method, you have to connect a travel sensor.
There are following options, priority-wise ordered:
1. Use the same connection point as used by the manufacturer during factory routine tests.
2. Use the same connection point as during the commissioning of the circuit breaker on site.
3. Connect the travel sensor as close to the main contacts as possible. However, do not touch the
integrity of the circuit breaker.
4. On a ganged operated circuit breaker – Pick the pole which is closest to the spring operating
mechanism.
