4.1 General description
M 1 alarm contactor
The M 1 alarm contactor is a float switch that automatically sets KSB alarm switchgear
AS0, AS2, AS4, AS5, ASW4 or ASW8 to alarm status when the water level in the
collecting tank of the Ama-Drainer-Box is too high.
M 1 K alarm contactor
The M 1 K alarm contactor is a float switch that responds when the water level in the
collecting tank of the Ama-Drainer-Box is too high by
- automatically sending an alarm signal to the KSB AS 1-M alarm switchgear and
- automatically triggering an acoustic warning signal in washing machine interrupter
GEWAS191ANGL, causing the devices connected to the interrupter to be de-
energised.

4.4 Design details
▪The M 1(K) alarm contactor is a magnetic float switch working according to the
non-contacting principle.
▪It comprises:
–A connection element with PG7 cable gland
–A 5 m connection cable (2x0.34mm2)
–A sensor tube with a reed contact and the float
As the liquid level rises, the float with the incorporated annular magnet moves
upwards.
In the switching range of the reed contact, the resulting magnetic action triggers a
switching signal.
If the float leaves the contact’s range as the liquid level drops, the reed contact will
return to its original position.
