Alarm Relay Connection
The alarm relay connection provides a non-voltage relay capable of switching any 230V source up to 16A.
Three contacts are provided, Common, NO and NC.
Level Sensor Connection
Levels sensors are connected to terminal con11, sensors supplied are reed type mini floats installed through
the tank wall, conventional float switches, capacitive, vibrating fork, or other sensors may be used al long as
they provide a closed circuit when dry and open circuit when immersed.
To install the supplied sensors drill a 16mm hole to each sensor and fit so that they lie horizontal when dry
and flap upwards when immersed. Ensure minimum 50mm spacing between each sensor.
For cable lengths exceeding 10m a shielded cable is recommended particularly is the cable is run near to
mains power circuits, this will help to prevent induction of stray voltages from nearby circuits which may
cause false readings.
