Electrical connections as per NFC15-100 standard
This connection must be made by a qualified
and trained technician. To make 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.
CO Stats / CO detector
COST is a fixed CO detector.
Symbols used
For your safety and in order to avoid any damage of the device,
please follow the procedure described in this document and read
carefully the notes preceded by the following symbol:

- If needed, press quickly on 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 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).
Measurement (m) > Threshold (S) during the time-
delay T1: Alarm activation.
Measurement (m) < Threshold (S) - Hysteresis (H)
during the time-delay T2: Alarm deactivation.
Fixed back housing
- 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

In falling edge mode, the hysteresis allows to the transmitter to stay in alarm when the measurement is between the
Class II
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 time-delay 1 and the time-delay 2 (600 seconds maximum)
- In rising 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 minus the hysteresis.
Setting procedure: "Time 1" for the time-delay 1 is displayed then the time in second. The first digit blinks, press
briefly on the button and scroll the figures. Press on the button more than 3 seconds to validate. Repeat the process
until the last digit to set the time-delay 1 value (from 0 to 600 s) and validate. "Time 2" is displayed the time in
second. Repeat the process to set the time-delay 2.
Rising edge (1 threshold): the alarm goes off when the measurement exceeds the threshold
Mode
and stops when it is below the threshold.
Falling edge (1 threshold): the alarm goes off when the measurement is below the threshold
Mode
and stops when it exceeds the threshold.
Monitoring (2 thresholds): the alarm goes off when the measurement is outside the defined
Mode
low and high thresholds.
Rising edge
Falling edge
Measurement (m) < Threshold (S) during the time-
delayT1: Alarm activation.
Measurement (m) > Threshold (S) + Hysteresis (H)
during time-delay T2: Alarm deactivation.
Monitoring
The alarm goes off when the measurement is
outside the low and high thresholds.
