Besides basic operations, the DOMOTIC Series electrolysis system has three inputs for voltage-free contacts, enabling the connection of
additional external controls. They are located on connector [CN7] of the power card (Fig. 17).
Fig. 17
The logic associated to these three inputs can be programmed during the system configuration process (see point 5.2)
o
[FS] OPTIONAL EXTERNAL FLOW DETECTOR CONTROL (not included with the equipment): input for potential-free
contact. When the contact connected to this input is open (external flow detector at rest), and the [FS] is configured as [FS1c],
the electrolysis system switches off due to the flow alarm. Connect the external flow detector wiring to the respective input
[FS], placed in the [CN7] connector, on the unit’s power card.

o
[co] AUTOMATIC COVER CONTROL: input for potential-free contact. Depending on the status of the contact connected to
it on the automatic cover’s electric panel, this input enables you to programme a reduction of the equipment’s output current to
a percentage of its nominal value.
