12. Maintenance
NOTE
The Digistart IS soft starter is not user serviceable. The unit should only be serviced by authorised service personnel.
Unauthorised tampering with the unit will void the product warranty.
 Before carrying out any work, disconnect and lock the starter's power supply and wait 2 minutes to ensure that the
capacitors have discharged.
 When the starter trips, fatal residual voltages may remain at the output terminals and in the starter.
 During maintenance operations performed with the starter switched on, the operator must stand on an insulated surface
which is not connected to ground.
 During work on a motor or its power supply cables, ensure that the power supply of the corresponding starter is
disconnected and locked.
 Protective covers must remain in place during tests.
There are very few maintenance and repair operations for the user to perform on Digistart IS soft starters. Regular servicing
operations and simple methods for checking that the starter is operating correctly are described below.
12.1 Care
Printed circuits and internal components do not normally require any maintenance. Contact your local distributor or the nearest
approved repair company in the event of a problem.
CAUTION
Do not dismantle the printed circuits while the starter is still under warranty. Unauthorised tampering with the unit will
void the product warranty.
Do not touch the integrated circuits or the microprocessor either with your fingers or with materials which are charged or live.
Ground yourself, as well as the workbench or the soldering iron, while performing any work on the circuits.
From time to time, check that the power circuits are correctly tightened.
12.2 Measuring the motor current
The current drawn by the motor and the starter input current can be measured approximately using a conventional moving coil
ammeter.
12.3 Measuring the input and output power
The starter input and output power can be measured using an electrodynamic instrument.
12.4 Exchanging products
CAUTION
Products must be returned in their original packaging or, if this is not possible, in similar packaging, to prevent their
being damaged. Otherwise, replacement under warranty could be refused.
