probes and no timer: -

cut the correct probes to required length.

remove 25mm of insulation from end of probes.

set DIL switches as required, see section 2.2

e.g. for filling a tank between two levels (start probe "A" and

stop probe "B"): to energise relay 1 when start probe

becomes dry and release relay 1 when stop probe becomes

wet, set all DIL switches to OFF except switch 3 which is set

to ON. Set timer to 0 seconds (Fully Anticlockwise).

LSM-P3-A: Emptying a tank between two levels,

using 3 probes and no timer: -

cut the correct probes to required length.

remove 25mm of insulation from end of probes.

set DIL switches as required, see section 2.2

e.g. for emptying a tank between two levels (start probe "B"

and stop probe "A"): to energise relay 1 when start probe

becomes wet and release relay 1 when stop probe becomes

dry, set all DIL switches to OFF except switches 1 & 3 which

are set to ON. Set timer to 0 seconds (Fully Anticlockwise).

LSM-P3-B: Low and High tank level alarms with

separate volt free output for each, using 3 probes

and a timer: -

cut the correct probes to required length.

remove 25mm of insulation from end of probes

set DIL switches as required, see section 2.2

e.g. for high and low level alarm: to energise relay 1 when

probe "B" becomes wet (high level alarm) and relay 2 when

probe "D" becomes dry (low level alarm), set all DIL

switches to OFF except switches 2, 5 & 6 which are set to

ON. To activate audible alarm (where fitted) at high level,

set switch 4 OFF, alternatively to activate audible alarm

(where fitted) at low level, set switch 4 ON.

LSM-TT-B: Twin Tank Level alarm

using optional LWP3 probes or

level switches.

1. Install Level probes/switches as per

instructions supplied with them.

2. set DIL switches as required, see

section 2.2. For low water level

alarm all DIL switches should be

OFF.
