SETUP PROCEDURE
SMART PROBE VERSION
1. Mount the unit in its actual position.
(See mounting procedure - pages 9-10)
Make sure that external ground wire is con-
nected between the outside ground screw on
the Gladiator housing and the roof/wall/side
of the silo/tank/vessel/chute. (For non metal-
lic tanks make sure that external ground
wire is connected between the same outside
ground screw on the housing and the gen-
eral plant ground potential).
2. Check where the actual level is relative
to the probe.
Make sure that product is not touching the
probe - ideally it needs to be > 500mm away.
(If the silo/vessel/tank/chute is very small
you must ensure that the material is as far
away as possible - it must not be touching
the probe).
3. Turn the power on.
The green LED will either stay on for 2 sec-
onds then begin ashing or stay on perma-
nently to indicate operation.
4. Select the required relay contact ac-
tion.
The Relay can switch ‘ON’ or ‘OFF’ as the
product approaches the probe and switch
‘ON’ or ‘OFF’ in response to an instrument
failure (for details see page 14). Set the relay
action selection switch position (FSL or FSH)
depending on your requirements.
5. Cancel inuence of mounting and/or
build up.
Do not proceed with this step unless the
product is not touching the probe. Ideally the
level needs to be > 500mm away.
Switch the Mounting Calibration switch to
‘CAL’ (ON) position. The Blue LED will blink
to indicate that mounting calibration is
now in progress.
Wait for at least 10 sec. then switch the
mounting calibration switch to ‘OFF’ position.
The blue LED should turn off after a short
time. The Blue LED will stay on if there
was a calibration error. If this is the case
please check that the probe is not touching
the product or the mounting, then try the
calibration again. If mounting calibration was
successful the blue LED should be off and
the Green LED should blink every 2 sec.
Unit is now able to cancel inuence of
mounting and/or build-up and probe history
has been cleared.
6. Select the sensitivity.
There are two adjustments controlling the
sensitivity of the switch point:
6.1. The ‘HI/LO’ sensitivity switch is used
to set your unit depending on the dielectric
properties of the product to be measured.
This switch sets the range of adjustment
possible with the sensitivity potentiometer.
If the material to be detected has a lower
dielectric constant than 10 - set the switch to
‘HI’ (ON) - default.
If material to be detected has a higher dielec-
tric constant than 10 - set switch to ‘LO’
If you are not aware of your material dielec-
tric constant – set the switch to ‘HI’ (ON)
- default.
6.2 The sensitivity potentiometer.
Set the potentiometer according to your
requirements. A 12 o’clock setting (50%)
- default, will cover the majority of instances
- for the remaining instances, turning the
potentiometer anti clockwise will decrease
sensitivity. Switch point will then occur with
the material nearer to the probe or more
in contact with the probe than before. The
reverse is also true.
