When the synchro-check relay is used under the
conditions specified in "Technical data", it re-
quires practically no maintenance. The relay
includes no parts or components that are sensi-
tive to physical or electrical wear under normal
operating conditions.
Should the temperature and humidity at the
operating site differ from the values specified,
or the atmosphere contain chemically active
gases or dust, the relay should be visually in-
spected in association with the secondary test-
ing of the relay. This visual inspection should
focus on:
- Signs of mechanical damage to relay case and
terminals
- Collection of dust inside the relay case; remove
with compressed air
- Signs of corrosion on terminals, case or inside
the relay

If the relay malfunctions or the operating val-
ues differ from those specified, the relay should
be overhauled. Minor measures such as change
of a plug-in-type PC board can be taken by
normal service personnel with the required skill.
In uncertain cases and if the fault is permanent
the manufacturer or his nearest representative
should be contacted for further information
about checking, overhaul and recalibration of
the relay.
Note!
The protection relay contains circuits that are
sensitive to electrostatic discharge. If you have
to withdraw a relay module, ensure that you are
at the same potential as the module, for instance,
by touching the case.
Note!
Static protective relays are measuring instru-
ments and should be handled with care and pro-
tected against moisture and mechanical stress,
especially during transport.
