Connect the stroke sensor to a suitable monitoring device according
to the technical data provided with the monitoring device and that of
the stroke sensor - see chapter "Technical data".
Make sure that the monitoring/feed equipment installed by the cus‐
tomer is capable of evaluating the current variations of the Namur
sensor to indicate a stroke.
The following applies in areas at risk from explosion:
n
Note the details of the type examination certificate PTB 00 ATEX 2048
X for the Namur sensor NJ1.5-8GM-N as well.
1.
Install the cable which originates from the pacing relay - see the
figure in the chapter entitled "Overview of equipment and control
elements": Cable A, left.
The cable polarity is unimportant.
2.
Install the power supply cable to the pacing relay PCB - see the
figure in the chapter entitled "Overview of equipment and control
elements": Cable B, right.
Overloading
n
If the current through the relay becomes too high, it can be
destroyed by heating.
n
Fit a circuit breaker.
