WARNING
•
When Oxygen (OSU) is selected, fresh air (20.9 vol%) is
the output after the detector is started in the atmosphere.
For a specification where an alarm is triggered by the
AIR (normal oxygen concentration) output (e.g., 0 - 5
vol%), be careful of an alarm issue after the detector is
started.
CAUTION
•
Do not turn off the detector during the initial clear. The detector is reading the sensor memory during
the initial clear.
•
If a new sensor unit is installed or the sensor unit is replaced after the detector is started, the sensor
unit must be warmed up for a specified period which is determined depending on the type of the
sensor unit. Suggested warm-up time for SGU type sensor units is displayed in Maintenance Mode.
During the warm-up, the alarm activation and output signals are unstable. Prepare appropriately for
false alarms.
•
Because the pyrolyzer unit (PLU-70) must be warmed up for one hour, please warm it up with the
detector.
•
After the warm-up is completed, verify that the reading on the flow rate indicator corresponds to the
specified flow rate, and then perform a gas calibration.
