6.1 Product description
6.1.1 Function description
The switchgear is used to control a single electric pump in "sprinkler systems" in accordance with APSAD (T1-2).
In automatic mode the pump is switched on according to the unit pressure. Each pump has 2 pressure switches
at its pressure connection to monitor the pressure. Each pressure switch is controlled by a key switch.
When the pump is started, it can only be switched off manually and only when the pressure has been reached in
the unit.
In manual mode the start of the pump is activated from the HMI.
The start-up of the pump is done by means of a start-up tank, the filling of which is controlled by a float switch.
States of system operation such as availability, pump operation, malfunctions, etc. are visually indicated by
LEDs on the front of the switchbox and equally by a buzzer. Operating parameters such as current or voltage
values are displayed on the screen. The operation is performed by means of the rotary knob, key switches and
buttons accessible on the front of the switchbox.
Potential-free contacts are available for transmitting the collective run or malfunction signals to a possible
BMS (building management system).
