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)
