Jumper 2

is used to assign functions to the external interface when a potential-free switching
contact is connected (pressure monitor: Opener (normally closed NC) / other sensors: Closer
(normally open NO) and for integration into a house control system.
The position of the jumper may only be changed in a voltage-free state.

Interface used as analogue input
The 2-pin plug for jumper 2 is located on the rear side of the operating unit. The jumper 2 is not
plugged in at the factory and is located inside the accessories pack of the controller. It must be
attached if necessary. Jumper 1 is used for service settings and must be left as delivered to
ensure correct functioning of the controller.
If a pressure monitor with normally open contact is connected, e.g. if the sMove controller is exch-
anged, it must be configured as a normally closed contact (switch with changeover contact) or, if
this is not possible, it must be replaced by a pressure monitor with normally closed contact.
It is not possible to connect a potential-free switch and an analogue input simultaneously. A
connected analogue input always has priority over a potential-free switching contact. If a pres-
sure monitor is connected, the pressure monitor has priority to other connected sensors.
If Jumper 2 is not attached and the sMove controller is integrated into an home automation
system, the following direct voltages must be set:
