5.1.
Plug-in unit
The relay’s construction allows a spare part in form of a plug-in unit. The outage
time can therefore be reduced to a minimum in case the relay should fail.
In case of malfunction, please consult your relay supplier.
The spare plug-in unit to be used for a certain relay is suitable if at least the first ten
characters in the order number are identical with those in the order number of the
case.
Note!
In order to obtain identical functionality to those of the original product, all
characters in the order number, except for those indicating a spare part, should match
the ones in the order number of the case.
The relay features a built-in mechanical coding system which helps preventing
dangerous situations from arising, should a non-suitable plug-in unit be fitted into a
relay case.
The plug-in unit is calibrated as a whole to achieve the best possible operation
accuracy and individual pieces of it should not be removed.
If the faulty plug-in unit is subject to guarantee and the fault is caused under
circumstances covered by the guarantee conditions, it should be returned for repair,
see section Guarantee.
Ordering of spare parts is done using the same ordering system as for ordering a new
relay.
5.2.
Battery
The battery for real-time clock and non-volatile memory can be purchased in stores
specialized in electronic components.
Recommended battery manufacturers and types are Panasonic of type BR2032, and
Rayovac of type BR2032.
Batteries of the recommended lithium BR-types cannot be recharged.
Danger!
Forcing a non-suitable plug-in unit into a case will break the relay
and may cause dangerous situations.
