Smart Probe Version
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 conductivity 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
conductivity than 1750µS/cm (4400µS/inch) -
set the switch to ‘HI’ (ON) - default.
• If material to be detected has a higher conductivity
than 1750µS/cm (4400µS/inch) - you may set the
switch to ‘LO’.
• If you are not aware of your material’s conductivity –
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 clockwise will increase
sensitivity.
• Increasing sensitivity maybe necessary if the liquid is
not detected when touching the probe.
7. Select the time delay
• Set the required delay using the Delay
potentiometer. (Default is 0 sec. at minimum
position) Turn the potentiometer clockwise if any
delay is required.
• Maximum rotation is ¾ of a revolution.
• Max delay is 20 sec. The selected delay will be used
for both an ON delay and an OFF delay.*
8. Test function
(used to check for malfunction of unit from
remote position, PLC, SCADA etc)
• Select the desired Test function by switching the
‘Test’ switch (Default = ‘OFF’).
• TEST’ (ON) Position:
• Test function is selected.
• Test terminal (terminal number 4 of Smart probe) is
used as an input to the unit.
• The test function allows you to check the
functionality of the unit.
• Applying a ground wire to the Test terminal will
change the state of the relay. It will hold this state
until the ground is removed, then it will change
back to the standard running mode.
• If the unit was in a Fail mode then the relay will not
change status.
• ‘OFF’ (Default) Position:
• Fail safe output function is selected.
• Test terminal (terminal number 4 of Smart probe)
will function as an open drain drive.
• This can be used to drive a relay or an active low
PLC input to detect a Fail condition.
• In normal operation mode the Test terminal will
output Zero Volts (Short to GND).
• In Fail or unpowered mode the Test terminal will be
open circuit.
See page 14 for further information.
Setup Procedure
Gladiator Conductivity Switch Series
*Setting of different time ranges for the delay
potentiometer for ON delay and OFF delay is possible
using a PC connected via GosHawk2 software. By
default, both will have the same time adjustment range
(20 sec max) and adjustment will result in equal ON
delay and OFF delay.
