the connection, the transmitter must not be energized.
Settings and use of the transmitter
Threshold 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.
Working principle:
– By pressing on the button more than 3 seconds, you can validate the setting
and go to the next setting.
– By pressing quickly on the button, you can increment a value and scroll down
the different option or values.
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 on the button to switch the relay in positive
security, the relay is de-energized during an alarm ondition or a current
breaking, “POS” is displayed.
– Press 3 s on 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 3 s the button, “Alarm” screen is displayed with “On” or “Off”
blinking (according to the last saved configuration).
– Press quickly on the button, the display changes from “On” (activated alarm)
to “Off” (deactivated alarm).
– Press 3 s the button to confirm the setting. If the alarm is deactivated,
the instrument displays the measurement; if the alarm is activated, the
instrument displays the following setting.
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.

---|---|---
Measurement (m) > Threshold (S) during the timedelay T1: Alarm activation.
Measurement (m) < Threshold (S) – Hysteresis (H) during the time-delay T2:
Alarm deactivation.| Measurement (m) < Threshold (S) during the timedelayT1:
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.
– 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.
Set the threshold(s) value
The first digit blinks, it corresponds to the positive (0) or negative (-)
setting of the threshold value. Press briefly on the button to select the sign
for the threshold value. Press on the button more than 3 seconds to validate.
The second digit blinks, press briefly on 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.
Set the hysteresis
The hysteresis is only for the rising edge and the falling edge modes.
In rising edge mode, the hysteresis allows to the transmitter to stay in alarm
when the measurement is between the threshold and the threshold minus the
hysteresis.
Ex: for a 100 ppm threshold and a 10 ppm hysteresis, the instrument will stay
in alarm when the measurement will be between 100 and 90 ppm.
In falling edge mode, the hysteresis allows to the transmitter to stay in
alarm when the measurement is between the threshold and the threshold plus the
hysteresis.
Ex: for a 100 ppm threshold and a 10 ppm hysteresis, the instrument will stay
in alarm when the measurement will be between 100 and 110 ppm.
The first digit blinks, set it pressing the button briefly several times then
press on the button more than 3 seconds to set the following digit.
Once the hysteresis is set, press the button more than 3 seconds to validate
and set the time-delays.
Set the hysteresis
The hysteresis is only for the rising edge and the falling edge modes.
In rising edge mode, the hysteresis allows to the transmitter to stay in alarm
when the measurement is between the threshold and the threshold minus the
hysteresis.
Ex: for a 100 ppm threshold and a 10 ppm hysteresis, the instrument will stay
in alarm when the measurement will be between 100 and 90 ppm.
In falling edge mode, the hysteresis allows to the transmitter to stay in
alarm when the measurement is between the threshold and the threshold plus the
hysteresis.
Ex: for a 100 ppm threshold and a 10 ppm hysteresis, the instrument will stay
in alarm when the measurement will be between 100 and 110 ppm.
The first digit blinks, set it pressing the button briefly several times then
press on the button more than 3 seconds to set the following digit.
Once the hysteresis is set, press the button more than 3 seconds to validate
and set the time-delays.
– In falling edge mode, the time-delay 1 corresponds to the time lag before
the alarm goes off when the threshold has been reached. The time-delay 2,
corresponds to the time lag before the alarm stops when the measurement is
lower than the threshold plus the hysteresis.
The setting procedure is the same as the rising edge procedure.
– In monitoring mode, the alarm of the transmitter goes off when the
measurement is below the lower threshold and higher the high threshold. The
time-delay 1 corresponds to the time lag before the alarm goes off when the
measurement is below the lower threshold and higher the high threshold. The
time-delay 2 corresponds to the time lag before the alarm stops when the
measurement is between the lower and higher thresholds.
The setting procedure is the same as the rising edge procedure.
Configuration via LCC-S software (optional)
The software allows to set the alarms, the thresholds, the relay action, the
hysteresis and the time-delay of the device.
• To access the configuration via software:
– Set the DIP switches as shown beside.
– Connect the cable of the LCC-S to the connection of the transmitter.
• Please refer to the user manual of the LCC-S to make the configuration.
The configuration of the parameters can be done either with the DIP switch or via software (you can not combine both solutions). Switch off the sensor before settings process.
Mounting
To mount the transmitter, mount the ABS plate on the wall (drilling: Ø 6 mm,
screws and pins are supplied).
Insert the transmitter on the fixing plate (see A on the drawing beside).
Rotate the housing in clockwise direction until you hear a “click” which
confirms that the transmitter is correctly installed.
Ambient model has not any fixing plate.
4 fixing holes are inside the back housing. Use them to install the
transmitter on the required location.
Maintenance: please avoid any aggressive solvent.
Please protect the transmitter and its probes from any cleaning product
containing formalin, that may be used forcleaning rooms or ducts.
Precautions for use: please always use the device in accordance with its
intended use and within parameters described in the technical features in
order not to compromise the protection ensured by the device.
