GENERAL DESCRIPTION

The LSM Range units offer an easy solution to many water level control and alarm functions.

They can be used either with conductive probes in suitable conductive fluids or, with float switches in non

conductive fluids.

They have been used for emptying, filling, or level warnings within storage tanks (i.e. low or high

level) amongst many other applications, of which, some are shown within this instruction manual.

The LSM-P series come assembled with sleeved 4mm diameter 303 stainless steel probes, at a length of 1

metre, which can be cut to suit most tanks.

In applications where it is not possible to make use of the integral probes, model LSM is available, allowing

wall mounting of the unit remote from the tank/pit and using up to 4 remote probes which can be up to 15

metres from the control unit.

Units are supplied in a weatherproof case to IP55 Standard BS5490 (1977) with two glands, which accept

cables from 6 to 8 mm in diameter, other sizes on request.

Supply voltage: Standard 240V AC 50HZ 1Ø, from an isolating switch and 2 Amp fuse - NOT SUPPLIED.
