2. Hold finger on button to scroll quickly through values or touch button repeatedly to move through values more slowly.
3. When the desired value is displayed, wait until Latching option appears.
4. To change warning to latching or non-latching, touch button when the option is displayed.
5. Touch button when “Finished?” is displayed to exit.
Alarm Settings
Set Alarm level and whether warning is latching or non-latching.
1. Go to Sensor Setup menu and select “Finished?” until Alarm displays.
Alarm will scroll across the screen and the current Alarm level will be displayed.
2. Hold finger on button to scroll quickly through values or touch button repeatedly to move through values more slowly.
3. When the desired value is displayed, wait until Latching option appears.
4. To change alarm to latching or non-latching, touch button when the option is displayed.
5. Touch button when “Finished?” is displayed to exit.
Alarm Relay Settings is the last Sensor Setup menu. “Finished?” will save changes and take the user back to Setup
menus.
If the Alarm Relay is configured to be non-latching, the Alarm Relay output must be connected to an auxiliary device
that performs the latching function.
Diffusion Supervision
Diffusion supervision actively monitors the sensor inlet for obstructions. If an obstruction is detected, the sensor will go into a
fault mode to alert users and the control room that it is not seeing gas due to an obstruction. Objects residing directly on or in
the sensor inlet that result in a significant impact to the gas path are very likely to be detected by Diffusion Supervision.
Examples include paint, tape, water, and dirt. Small amounts of these materials can be visible on the inlet while not impacting
the gas path enough to trigger a Diffusion Supervision Fault. A fault signal will only be sent out when the system determines
that the amount of material that has accumulated on or inside the sensor inlet is negatively affecting the gas path.
Even if a Diffusion Supervision Fault has not been triggered, it is good practice to clear any foreign material from the
sensor inlet if any is observed while inspecting the sensor.
To enable or disable Diffusion Supervision:
1. Go to Sensor Setup menu.
2. Touch button when Diffusion Supervision appears.
3. Select Sensor1 or Sensor2.
Current status (enabled/disabled) displays.
4. Touch button to toggle to desired status.
5. Select "Finished?".
Sensor Reset - Last option in Sensor Setup
NOTICE
The sensor goes into a Sensor Configuration Reset fault (F007) and must be calibrated after a sensor reset.
