6.4 Switching and make-up variants
Select the make-up variant in the Customer menu of the device controller, see
chapter 7.8 "Parametrising the controller in the Customer menu" on page 13 .
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.
6.4.1 Pressure-dependent "Magcontrol" make-up mode

4 "WC" make-up line
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.

4 "WC" make-up line
The "Levelcontrol" operating mode is set in the Customer menu of the Servitec
controller. This operating mode is used for facilities with pressurisation stations
and enables flexible operation at constant pressure.
Demand-matched water make-up takes place depending on the measured water
level in the expansion vessel of the pressurisation station. The "LIS" pressure
transducer determines the water level and sends this value to the controller of
the pressure maintaining station. This sends a 230 V signal to the Servitec
controller if the water level is too low. Water make-up takes place in a controlled
manner by monitoring the make-up time and the make-up cycles via the "WC"
make-up line.
6.5 El ectrical connection
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.
The following descriptions apply to standard systems and are limited to the
necessary user-provided connections.
1.
Disconnect the system from the power source and secure it against
unintentional reactivation.
2. Remove the cover.
DANGER Risk of serious injury or death due to electric shock. Some
parts of the device's circuit board may still be live with 230 V even after the
device has been physically isolated from the power supply by pulling out of
the mains plug. Before you remove the covers, completely isolate the
device controller from the power supply. Verify that the main circuit board
is voltage-free.
3. Install a screwed cable gland suitable for the respective cable. M16 or M20,
for example.
4. Thread all cables to be connected through the cable gland.
5. Connect all cables as shown in the terminal diagram.
– For installer supplied fusing, comply with the connected loads of the
device , see chapter 5 "Technical data" on page 6 .
6. Install the cover.
7. Connect the mains plug to the 230 V power supply.
8. Activate the system.
The electrical connection is completed.
