5.3 Routine safety check
In case of misadjustment of the relay, e.g. selection of non-assigned switch positions, the relay operates with the
following setting values.
I
S
= upper rated CT current
Characteristic = DEFT
I> = Deactivated (Exit)
t
I>
= 0.04 s
I>> = 20 x I
S
t
I>>
= 0.04 s
With earth fault element
I
E>
= 2.5 x I
S
t
IE>
= 0.1 s
A circuitry is integrated to give an additional back-up protection in case of processor or storage errors. By this cir-
cuitry a short-circuit protection with the following trip values is guaranteed:
 I>> = 20 times highest rated CT current
 tI>> = 40 ms
The relay option WIC1-xxx-W works with an additional backup-protection when
 The watch-dog of the microcontroller responded,
 0.8 times lowest rated CT current is flowing,
 the energy storage is charged (charging time is 1s at lower rated CT current),
5.4 Fault value memory
A fault value memory is integrated in the WIC1 where data of the latest fault occurrence is stored. The stored in-
formation can only be read out via the PC interface. The following fault references are available:
 the protective element causing the trip or an externally triggered trip
 values of the trip current in the individual phases or earth fault currents (with E type)
