3.2.5 Functional faults
If an internal functional fault occurs, all of the three LEDs flash. An error code
will appear on the display (E01…E32). In such a case please contact the
Bender Service.
3.2.6 Setting the number of reload cycles
If faults occur only temporarily, but recurrently, in the system being monito-
red, with the fault memory M deactivated, the alarm relays would switch syn-
chronously to the error status.
RL in the out menu can be used to limit the number of these changeover
processes. As soon as the preset number of switching cycles is exceeded, the
fault memory will come on and an activated alarm remains stored.
3.2.7 Assigning alarm categories to alarm relays K1/K2
The alarm categories device error, residual current I
Δ
n1
, residual current I
Δ
n2
or
alarm by device test can be assigned to the alarm relays via the "out" menu.
3.2.8 Time delays
t
,
t
on
and
t
off
The times t , t
on
and t
off,
described below, delay the output of alarms via LEDs
and relays.
Start-up delay
t
After connection to the supply voltage U
s
, the alarm indication is delayed by
the preset time t (0…10 s).
Response delay
t
on1/2
If the residual current increases above or falls below the response value, the
residual current monitor needs the response time
t
an
before it signals an
alarm. A set response delay t
on1/2
(0…10 s) adds up to the device-related
operating time t
ae
and delays alarm signalling (total delay time t
an
= t
ae
+ t
on
).
In order to comply with the disconnection time of ≤ 50 ms
required by AS/NZS 2081:2011, the response delay t
on1/2
has
to be set to 0 seconds (factory setting).
