Switching and make-up variants

Select the make-up variant in the Customer menu of the device controller,
 10.1.1 "Customer menu",  39.
Choose from one of the following make-up variants in the Customer menu:
• Pressure-dependent "Magcontrol" make-up.
– In a facility system with diaphragm expansion tank.
• Level-dependent "Levelcontrol" make-up.
– In a facility system with pressure maintaining station.

The "Magcontrol" operating mode is set in the Customer menu of the Servitec
controller. This operating mode is used for plant systems with a diaphragm-type
expansion vessel. The make-up action depends on the pressure. The required
"PIS" pressure sensor is integrated in the Servitec. The "DC" degassing lines are
connected close to the diaphragm-type expansion vessel. In this way precise
pressure monitoring is enable for demand-matched make-up as.
 Note!
Connect the degassing lines on the return side of the system upstream
of the hydraulic switching point. In this manner the permissible
temperature range of 0° - 90°C is adhered to.

The "Levelcontrol" operating mode is set in the Customer menu of the device
controller. This operating mode is used for facility systems with pressure-
maintaining stations. The make-up with water depends on the filling level in the
expansion vessel of the pressure-maintaining station. The "LIS" pressure
transducer determines the filling level and sends this value to the controller of
the pressure maintenance station. The controller sends a 230 V signal to the
device controller when the filling level in the expansion vessel has fallen below
the set value.
Make-up with water is realised by regulating the motorized ball valve in the
"WC" make-up line. The device controller regulates the motor actuator of the
motorized ball valves. This ensures a controlled make-up with water and
monitoring of the make-up time and cycles.

DANGER
Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
• Ensure that the system is voltage-free before installing the device.
• Ensure that the system is secured and cannot be reactivated by other
persons.
• Ensure that installation work for the electric connection of the device is
carried out by an electrician, and in compliance with electrical engineering
regulations.
For the electrical connection, you must differentiate between a connection
component and an operating component.
