NOTICE
The FAN output has a limited capacity of 220~240 V AC –
0.5 A.
Do NOT use the FAN output to directly power the fan.
Instead, use the output to energise a relay that controls the
fan circuit.

SVS output (external alarm)
The SVS output is a potential-free contact on terminal X6M that
closes in case a leak is detected in the SV unit.
The SVS output must be used when an external alarm is required
(see
"12.3 To determine the required safety measures"

INFORMATION
It is important that all information in this chapter is read
sequentially by the installer and that the system is
configured as applicable.
16.1
Making field settings
16.1.1
About making field settings
To configure the SV unit, you MUST give input to the SV unit's main
PCBs (A1P and A2P, depending on the unit). This involves the
following field setting components:
▪ Push buttons to give input to the PCB
▪ A display to read feedback from the PCB
▪ DIP switches
The PCBs are located as shown below:
A1P
A2P

Main PCB A1P

Main PCB A2P (only for SV6~8A)
Note:
Some field settings need to be made on all main PCBs (A1P
and A2P) of the same SV unit. For more information, see
37].
Mode 1 – monitoring settings
Mode 1 can be used to monitor the current situation of the SV unit
Mode 2 – field settings
Mode 2 is used to change the field settings of the system. Consulting
the current field setting value and changing the current field setting
value is possible.
In general, normal operation can be resumed without special
intervention after changing field settings.
