Control Menu
Normal Display
Alarm pictograms will appear and disappear in
along with the alarm conditions detected by a
given sensor. The display shows gas level
readings, which may not always be identical to the
status of a relay. Under normal conditions, alarm
pictograms reflect relay status.
Example: LS and HS relays are configured to run
on a delayed trigger. Pictograms do not take this
delay interval into consideration. So it is possible
that the LS or HS relay is on, while the alarm
pictogram does not display on screen, due to the
alarm delay.
Cyclical display
This menu allows you to view all of the activated
sensors on screen, at a display rate of one sensor
every two seconds.
Event display
This menu allows you to view the status of all
sensors in alarm mode, faulting, or in calibration,
at a rate of one sensor every two seconds.
Sensor Display
This menu allows you to freeze the display on a
specific sensor by selecting the line and the
module number (The program automatically
selects active sensor modules).
Touching the [ OK ] key once will bring up the
sensor name, the abbreviated gas name, the gas
level and unit of measure (ppm, % LEL, $v/v).
If the sensor is faulting, “Def” will display in place
of the level reading.
Select the line or the sensor (if appliable) using the
[ ] [ ] (horizontal) keys.
Select the line number or the sensor number (if
appliable) using the [ ] [ ] (vertical) keys.
Press [OK] to select the sensor.
Press [OK] a second time to display both the gas
reading level and the 4 averaged readings if
average readings were activated. If averaging was
not activated, < > will display on screen.
If a communication fault occurs, the value will be
replaced by < > and the averages will stop
on the last calculated value.
For all other faults, the gas level will be displayed
in order to help the user identify the problem.
