Within the scope of servicing and maintenance following checks of the unit hardware have to be conducted:
Component
Step
Interval/How often?
Output Relays
Please check the Output Relays via
Test menu Force/Disarm
(please see chapter Service)
Every 1
‒
4 years, depending on ambient
conditions.
Digital Inputs
Please supply a voltage to the Digital
Inputs and control if the appropriate
status signal appears.
Every 1
‒
4 years, depending on ambient
conditions.
Current plugs and Current
measurements
Please supply testing current to the
Current measurement inputs and
control the displayed measure values
from the unit.
Every 1
‒
4 years, depending on ambient
conditions.
Voltage plugs and Voltage
measurements
Please supply testing current to the
Voltage measurement inputs and
control the displayed measure values
from the unit.
Every 1
‒
4 years, depending on ambient
conditions.
Analog Inputs
Please feed analog signals into the
measurement inputs and check
if the
displayed measure values match.
Every 1
‒
4 years, depending on ambient
conditions.
Analog Outputs
Please check the Analog Outputs via
Test menu Force/Disarm
(please see chapter Service)
Every 1

4 years, depending on ambient
conditions.
Battery
The device checks the battery as part
of its Self-Supervision, therefore no
dedicated testing activities are
required. If the battery is low, the
System LED flashes red/green, and an
error code is generated (see
Troubleshooting Guide).
In general the battery lasts more than
10 years.
Exchange by manufacturer.
Notice: The battery serves as buffering of the clock
(real time clock). There's no impact on the
functionality of the device if the battery breaks down,
except for the buffering of the clock while the unit is
in de-energized condition.
Self-monitoring contact
Switch of the auxiliary supply of the
unit. The Self-monitoring contact has
to dropout now. Please switch on the
auxiliary supply again.
Every 1
‒
4 years, depending on ambient
conditions.
Mechanical mounting of the
unit of the cabinet door
Check the torque related to the
specification of the Installation chapter.
With each maintenance or yearly.
Torque of all cable
connections
Check the torque related to the
specification of the Installation chapter
which describes the hardware
modules.
With each maintenance or yearly.
We recommend to execute an protection test after each 4 years period. This period can be extended to 6 years if a
function test is executed at least every 3 years.
