6 Description and function
6.1 Description of the product (Fig. 1)
6.1.1 Function description
The switchgear is used to control an individual
electric pump in sprinkler systems, in accordance
with EN 12845. The pump can be switched on and
off by the control depending on the pressure. The
system’s operating statuses, such as standby,
pump operation, fault etc., are displayed visually
by LEDs on the door and operating parameters
such as current or voltage values are shown on the
display. The system is operated using the rotary
knob and the buttons in the door.
Potential-free contacts are available for forward-
ing run or fault signals messages to the building
management system.
6.1.2 Set-up of the switchgear (Fig. 1)
The set-up of the switchgear depends on the
capacity of the pump to be connected. It consists
of the following main components:
• Main switch: Switches the switchgear on/off
(Fig. 1, item 2)
• Human-machine interface (HMI): signal lamps or
display for indicating the operating status (e.g.
standby, fault, and rated pump current), rotary
knob and buttons for menu selection, parameter
input and operation (Fig. 1, item 1)
• Base board: printed circuit board with microcon-
troller (Fig. 1, item 6)
• Measurement board: converting current and volt-
age values (Fig. 1, item 7)
• Transformer: 3-phase pump current measure-
ment (Fig. 1, item 4)
• Fuse protection for drives: fusing for the pump
motor by means of fusible cut-outs (Fig. 1, item 3)
• Contactors/contactor combinations: contactors
for switching on the pumps (Fig. 1, item 5)

6.2 Function and operation
DANGER! Risk of fatal injury!
When working on the open switchgear, there’s a
danger of electric shock from touching the live
components.
This work must only be carried out by qualified
personnel!
NOTE:
After connecting the switchgear to the supply
voltage, as well as after every mains interruption,
the switchgear returns to the operating mode set
before the power interruption.
6.2.1 Switchgear operating modes (Fig. 2)
Switching the switchgear on/off
After connection to the mains supply, the switch-
gear can be switched on or off using the main
switch. Once the main switch has been switched
on, the system is ready for operation after a few
seconds (the start phase). If the supply voltage is
within the set parameters, standby is indicated by
the signal lamp (Fig. 2, item 1) lighting up green.
Pump request
If the pressure drops below the set target pressure
at least one of the two pressure switches, the sig-
nal lamp lights up (Fig. 2, item 4). After a configur-
able delay period (see menu 1.2.5.1) (LED flashes),
the connected pump is activated. The signal lamp
(Fig. 2, item 2) lights up green, indicating that the
pump is in operation.
Once the pressure reaches or exceeds the target
pressure, the signal lamp (Fig. 2, item 4) goes out
again but the pump remains activated. The pump
has to be switched off manually. The signal lamp
(Fig. 2, item 2) then goes out.
Priming device
If the level of the pump priming tank falls below 
2/3, the float switch closes and the signal lamp
(Fig. 2, item 5) lights up white. After a configur-
able delay time (see menu 1.2.5.2) (LED flashes),
the pump activates and the signal lamp (Fig. 2,
item 2) lights up green. Once the pump priming
tank is full and the float switch opens again, the
signal lamp goes out (Fig. 2, item 5) and the pump
either switches off again automatically or it has to
be deactivated manually (see menu 5.2.2.0).
The signal lamp (Fig. 2, item 2) then goes out.
Voltage monitoring
To improve operational reliability, the mains
power supply is monitored continuously. To do
this, the correct supply voltage has to be set in
menu 1.2.1.1. The voltage is monitored individu-
ally between all three live wires. If no pump is run-
ning (standby), the voltage in the display switches
alternately between all three conductors. When
the supply voltage exceeds or drops below the
configurable tolerances (see menu 5.4.1.0 and
5.4.2.0), the signal lamp (Fig. 2, item 1) goes out
after a configurable delay (see menu 1.2.5.3) and
the collective fault signal (Fig. 2, item 6) lights up
yellow. If a fault occurs, the pump nevertheless
starts or continues running. Once the voltage is
back within the tolerance range, the fault is self-
acknowledging. The signal lamp (Fig. 2, item 6)
goes out and the signal lamp (Fig. 2, item 1) lights
up green again.
Current monitoring
The pump current is monitored while the pump is
in operation. To do this, the correct rated current
for the pump has to be set in menu 1.2.1.2. The
current is monitored individually in all three con-
ductors. If the pump is running, the pump current
in the display switches alternately between all
three conductors. The signal lamp (Fig. 2, item 2)
lights up green once the pump current reaches a
configurable minimum threshold (see menu
5.4.3.0). When the pump current exceeds or drops
below the configurable tolerances (see menu
5.4.3.0 and 5.4.4.0), the signal lamp (Fig. 2, item 6)
lights up after a configurable delay (see menu
1.2.5.5). If a fault occurs, the pump nevertheless
starts or continues running. Once the pump cur-
rent is back within the tolerance range, the fault
can be acknowledged. The signal lamp (Fig. 2,
item 6) goes out.
Monitoring hydraulic false start
Once the pump has started, the hydraulic output is
monitored by a pressure switch on the pump. If
the pump does not build up any pressure after the
configurable period of time (see menu1.2.2.2) and
the pressure switch on the pump remains open,
the signal lamps (Fig. 2, item 6) and (Fig. 2, item 3)
light up. If the pump is running, the relevant pres-
sure has been reached and the pump pressure
switch is closed accordingly, the fault can be
acknowledged. The signal lamps (Fig. 2, item 6)
and (Fig. 2, item 3) go out and the signal lamp
(Fig. 2, item 2) lights up green.
Monitoring electric false start
Once the pump has started, the pump’s electric
output is monitored for a configurable period of
time after the start (see menu 1.2.2.1). To do this,
the correct pump output has to be set in menu
1.2.1.3. If the configurable minimum threshold (see
menu 5.4.5.0) is not reached within the monitoring
period, the signal lamps (Fig. 2, item 6) and (Fig. 2,
item 3) light up after a configurable delay period
(see menu 1.2.5.4) plus the time for the star/delta
changeover (see menu 1.2.5.6). If the pump is run-
ning and the relevant pump output has been
reached, the fault can be acknowledged. The signal
lamps (Fig. 2, item 6) and (Fig. 2, item 3) go out and
the signal lamp (Fig. 2, item 2) lights up green.
Logic reversal of the collective fault signal (SSM)
The required logic of the SSM can be set in menu
5.5.2.0. In this case, it is possible to select
between negative logic (falling edge in case of a
fault = “fall”) or positive logic (rising edge in case
of a fault = “raise”).
