Mounting preparations

In general, the electronics module can be also exchanged within the
type series against an electronics with another signal output (e.g.
relay against transistor output).
If you want to use an electronics module with a different signal output,
you can download the corresponding operating instructions manual
from our homepage under Downloads.

adjustment elements of the new electronics module to the same
setting of the old one.
