2.1

The following drawings illustrate typical examples of applications and installations using Relay 1 only. For

Relay 2 use, substitute probe connections (C & D) and switch numbers (5, 6 & 7) as appropriate.

LSM-P3-A: High tank level alarm or Emptying a

sump, controlled by 2 probes and a timer: -

Cut the correct probes to required length.

remove 25mm of insulation from end of probes.

set DIL switches/timer as required, see section 2.2

e.g. for high level alarm: to energise relay 1 (with sounding

of audible alarm where fitted) when water touches probes,

set all DIL switches to OFF except switch 2 which is set to

ON (Relay 1 delay off). Set timer to maximum (fully

clockwise = 255 seconds).

LSM-P3-A: Low tank level protection of pumps with

fail safe relay operation by 2 probes and a timer: -

cut the correct probes to required length.

remove 25mm of insulation from end of probes.

set DIL switches/timer as required, see section 2.2

e.g. for level protection of pumps with fail safe relay

operation: to energise relay 1 when water touches probes,

set all DIL switches to OFF (Relay 1 delay on). Set timer to

30 seconds to delay pumps restarting.

LSM-P3-A: Low tank level alarm or Filling a tank,

controlled by 2 probes and a timer: -

cut the correct probes to required length.

remove 25mm of insulation from end of probes.

set DIL switches/timer as required, see section 2.2

e.g. for low level alarm: to energise relay 1 (with sounding of

audible alarm where fitted) when probes become dry, set all

DIL switches to OFF except switches 1 & 2 which are set to

ON (Relay 1 delay off). Set timer to maximum (fully

clockwise = 255 seconds).
