To connect Mycom relays
Mycom S CPM153 has one alarm contact and five additional contacts. Via these five contacts, you
can control controller, limit contactor, water and cleaning agent supply for the Chemoclean

1. Connect the alarm contact to terminals "41" and "42".
2. Connect the additional contacts as follows:
The function assignment (controller, limit contactor, etc.) to each relay depends on your
configuration.
When using the NAMUR assignment, for example, functions of the alarm relay and the first
two additional relays are preset (see NAMUR assignment below). Without NAMUR
assignment, you can assign any function to all five additional relays.

Note!
• You can assign up to three relays to the controller.
• You can switch the contact type "Active open" / "Active closed" via software.
