Rev 1.2, June 2008
SETUP PROCEDURE
SMART PROBE VERSION
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 18 for further information.
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.
* Setting of different time ranges for the delay potentiometer for ON delay and OFF delay is possible us-
ing 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.
