Hardware migration for alarm contact

After opening and removing the
front of the pump (Fig. 7.21) you
can see the alarm relay with switch
contact (Fig. 7.20, Pos. 1) at the
board.
Depending on the position of the
jumper, both the NC and the NO
contact can be selected as the
alarm contact.
To switch, set jumper 3 from Pin 1
& 2 up to Pin 2 & 3.
In the as-delivered condition, the
normally closed contact is preset.
Changes to the circuit board may only be performed by service personnel or trained
