Configuration of the warning relay function
The relay can be reconfigured by means of two jumpers. (The original configuration is
marked on the label). The jumpers are placed on the PCB behind the rear cover, under
the set point potentiometer R213.
The contact function can be configured to either a normally energised contact (NE) or
a normally de-energised contact (ND).
Warning delay
It is possible to choose between No warning delay or 4 s warning delay from the
alarm occurs until the warning relay is activated.
If the system has capacitance to ground, it is recommended to use the 4 s time delay in
order to avoid "false" warning at power-up, or when capacitive load is switched on.
