6 Description and function

6.1 Description of the product (Fig. 1)
6.1.1 Function description
The switchgear is used to control a diesel pump in
sprinkler systems, in accordance with EN 12845.
The diesel engine is automatically started by the
control and the starter once the pressure switch is
tripped. A maximum of 6 start attempts are made.
Once the motor has started, it can only be stopped
manually if the pressure in the system has not
been reached.
The diesel engine can be started via a connected
float switch in order to automatically replenish the
pump priming tank and it can be switched off
according to the setting. The system's operating
status is displayed visually via LEDs and an LC dis-
play in the door. 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 1)
• Human-machine interface (HMI): LCD for display-
ing operating data (see menus), LEDs for display-
ing the operating status (operation/fault),
operating knob for
• menu selection and parameter input (Fig. 1,
item 2)
• Base board: printed circuit board with microcon-
troller (Fig. 1, item 4)
• Converter board: conversion of the voltage from
12 VDC to 24 VDC, conversion of the speed signal
(Fig. 1, item 5)
• Fuse protection for components: fuse protection
for control and connected components using fusi-
ble cut-outs (Fig. 1, item 7)
• Contactors/relay: contactors/relay for connecting
the starter and magnetic switch (Fig. 1, item 6)
• Chargers: chargers for automatic charging of the
starter batteries (Fig. 1, item 3)
