6 Description and function
6.1 Description of the product
6.1.1 Function description
The switchgear is used to control a pressure-
maintaining (jockey) 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
(e.g. standby, pump operation and fault) are dis-
played visually by LEDs on the door. In addition,
the operating mode can be changed using a rotary
switch.
A potential-free contact is available for forward-
ing a fault signal to the building management sys-
tem.
6.1.2 Switchgear set-up
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: for switching the switchgear on/off
• Human-machine interface (HMI): signal lamp for
displaying the operating status (standby, pump
operation and fault), rotary switch for selecting
the operating mode
• Fuse protection for drives: fusing for the pump
motor by means of a motor protection switch
• Contactors/contactor combinations: contactors
for switching on the pumps
• Manual/auto rotary switch: switch for selecting
“manual” operating mode (pump switched on
manually) and “auto” (pump switched on depend-
ing on pressure)
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.

English

6.2.1 Switchgear operating modes (Fig. 1)
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 instantly ready for operation.
Operational readiness is displayed by the signal 


lamp lighting up green.
Pump request
If the pressure falls below the target pressure on
the pressure switch, the connected pump is 


switched on. The signal lamp indicates that
the pump is operating.
Once the target pressure is reached or exceeded,
the pump immediately switches off. The signal 


lamp goes out.
6.2.2 Motor protection
Excess current protection
Direct-starting motors are protected by motor
protection switches with thermal and electro-
magnetic trip triggers. The trigger current must be
set directly on the motor protection switch.
The motor protection is also active in manual
mode, and leads to deactivation of the corre-
sponding pump.
6.2.3 Operation of the switchgear
Main switch
On/off (lockable in “off” position)
Manual/auto rotary switch
The rotary switch has two switch positions. In the
upper position, the system is in “auto” operating
mode. In the lower position, the system is in
“manual” operating mode.
“Auto” operating mode:
If the rotary switch is set to “auto” (upper posi-
tion), the pump is controlled according to the
pressure switch or the pressure.
“Manual” operating mode:
If the rotary switch is set to “manual” (lower posi-
tion), the pump is switched on immediately,
regardless of the pressure switch or pressure. The
pump remains continuously switched on for as
long as the rotary switch is set to “manual”.
6.2.4 Switchgear display elements
Operational standby
The “operational standby” signal lamp lights up
green when the system has a power supply and is
switched on via the main switch. The system is
ready for operation.
Pump operation
The “pump operation” signal lamp lights up green
when the pump is switched on and there are no
faults.
Fault
The “fault” signal lamp lights up yellow when the
motor protection switch has been tripped by
excess current in the pump.
