19.3.1 Installation and measurement setup
► Before starting to mount or to link a digital linear transducer, bring the circuit breaker into the open
position, discharge the disc spring column completely and de-energize the pump module which
primes the disc spring.
To mount the digital linear transducer:
1. Protect the circuit breaker drive rod with a clean cloth.
2. Screw in the adjustable plug screw completely.
3. In the driving mechanism, locate the hole where the linear slider pin should be placed.
4. Insert and guide the transducer above the drive rod carefully and gently.
5. Insert the linear slider pin into the hole of the driving mechanism’s moving plate.
6. Insert the two plug screws of the mounting base into the head of the respective Allen screws of the
circuit breaker.
7. Unscrew the adjustable plug screw, place its cap head into the upper Allen screw head, and then
tighten it gently with an open-ended spanner.
8. Plug the cable into the digital interface connector.
9. Remove the cloth from the circuit breaker’s rod.
