This connection must be performed by a
qualified and trained technician. To make
the connection, the transmitter must not
be energized.
NO: normally open
COM: common
NC: normally closed
•
Activate or deactivate an alarm
- Press the button for 3 seconds,
“CONF”
is displayed then
“NEG”
, meaning that the relay is in negative security, it is
excited during an alarm condition.
- If needed, press quickly the button to switch the relay in positive security, the relay is de-energized during an alarm
condition or a current breaking,
“POS”
is displayed.
- Press 3 seconds the button,
“Buzz”
screen is displayed with
“ON”
or
“OFF”
blinking. Briefly press on the button to
activate (
“ON”
) or deactivate (
“OFF”
) (according to the last saved configuration) the buzzer during an alarm condition.
- Press the button for 3 seconds,
“Alarm”
screen is displayed with
“On”
or
“Off”
blinking (according to the last saved
configuration).
- Press quickly the button, the display changes from
“On”
(activated alarm) to
“Off”
(deactivated alarm).
- Press the button for 3 seconds to confirm the setting. If the alarm is deactivated, the instrument displays the measure-
ment; if the alarm is activated, the instrument displays the following setting.
•
Thresholds configuration
The button allows to activate or not an alarm (threshold), to set the action of the alarm (edge), to set the
threshold(s) value, to set the time-delay and to acknowledge the alarm.
•
Set the threshold(s) value
The first digit blinks, it corresponds to the positive (0) or negative (-) setting of the threshold value. Press briefly the button to
select the sign for the threshold value. Press the button more than 3 seconds to validate.
The second digit blinks, press briefly the button to scroll the numbers. Press the button more than 3 seconds to validate.
Repeat the process until the last digit to configure the threshold value, validate the threshold and go to the following setting.
If the monitoring edge has been selected, the transmitter displays the setting of the second threshold.
Working principle:
- By pressing the button more than 3 seconds, you can validate the setting and go to the next setting.
- By pressing quickly the button, you can increment a value and scroll down the different option or values.
- Press briefly the button to select the trespassing direction then press the button more than 3 seconds to validate this
direction and set the thresholds.

Units setting – active switch
To set a unit of measurement, put the on-off switch 4 of the units as shown
beside.
Measurement (m) > Threshold (S) du-
ring the time-delay T1: alarm activation.
Measurement (m) < Threshold (S) -
Hysteresis (H) during the time-delay T2:
alarm deactivation.
Measurement (m) < Threshold (S) during
the time-delay T1: alarm activation.
Measurement (m) > Threshold (S) +
Hysteresis (H) during time-delay T2: alarm
deactivation.
The alarm goes off when the measurement
is outside the low and high thresholds.

Set the action of the alarm (rising edge or falling edge)
The edge determines the action of the alarm according to the trespassing direction of the threshold(s).
Rising edge (1 threshold): the alarm goes off when the measurement exceeds the threshold and stops
when it is below the threshold.
Falling edge (1 threshold): the alarm goes off when the measurement is below the threshold and stops
when it exceeds the threshold.
Monitoring (2 thresholds): the alarm goes off when the measurement is outside the defined low and
high thresholds.
Settings and use of the transmitter
To configure the transmitter, it must not be energized. Then, you can make the
settings required, with the DIP switches (as shown on the drawing below).
When the transmitter is configured, you can power it up.

Configuration by switch:
to configure the transmitter, unscrew the 4 screws from the housing then open it.
Please follow carefully the combinations beside with the DIP switch. If the combination is wrongly done,
the following message will appear on the display of the transmitter “CONF ERROR”. In that case, you will
have to unplug the transmitter, place the DIP switches correctly, and then power the transmitter up.
