TYPICAL INSTALLATION EXAMPLES
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: -
1.
Cut the correct probes to required length.
2.
remove 25mm of insulation from end of probes.
3.
set DIL switches/timer as required, see section 2.2
4.
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: -
1.
cut the correct probes to required length.
2.
remove 25mm of insulation from end of probes.
3.
set DIL switches/timer as required, see section 2.2
4.
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: -
1.
cut the correct probes to required length.
2.
remove 25mm of insulation from end of probes.
3.
set DIL switches/timer as required, see section 2.2
4.
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).
