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.
