7.2.4.1 Installing the alarm or fault report output
1 + 2 = Output low-level warning, empty report and fault
Input low-level warning active:
relay output connected
Input low-level warning active acc. fault container active:
relay output closed (function invertible see chapter
10.3.9
“Configuration/alarm output” or
7.2.4.3 “Hardware migration for
alarm contact”), relay output = potential-free relay contact,
load 24 V AC/DC 3 A ecc. 115/230V 3A
Fig. 7.19 Installing the alarm or default report output
ATTENTION
At 115V/230 V, a simultaneous connection of contact 1+2 (alarm output) and 3+4
(stroke signal output) is generally not permitted.
7.2.4.2 Installing the stroke signal output at 24 V / DC
3 + 4 = Stroke signal output
The contact is closed once with each stroke of the pump
Relay output = potential-free transistor output,
load 24 V, DC, 300 mA
Fig. 7.20 Installing the stroke signal output at 24 V / DC
7.2.4.3 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
technical personnel!
