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.
