4.2 How it works
The pumps are automatically switched on and off depending on the fill level:
ƒ Control MS-L.../MS-L...-O:
– The level is detected via a two-position control with a float switch for each
pump.
– The high water level is detected by a separate float switch.
ƒ Control MS-L...-LS:
– The level is detected via two switching points by a rod float sensor (4...20mA
signal).
– The high water level is detected by a separate switching point.
A follow-up time can be set for deactivation. When the high water level is reached,
there is:
ƒ A visual and audible alarm signal
ƒ Forced switch-on of all pumps
ƒ Collective fault signal activation
ƒ Activation of the external alarm signal (only Control MS-L2...)
