Diagnostic Mode 27
The monitor is equipped with a diagnostic mode that can display
critical, low lever parameters to help users identify problems. Refer to
Troubleshooting on page 38.
The diagnostic mode allows the user to set several low level parameters
which are very critical to the operation of the monitor. Extra care
should be taken when setting these low level parameters. If the user is
unfamiliar with these parameters and sets them incorrectly, it may cause
the monitor to shut down or malfunction. The diagnostic mode should
only be used by qualified personnel.
To switch the monitor to diagnostic mode, turn the monitor off.
Press and hold [Y/+] and
M together; release both keys when the unit
beeps. The monitor is now in diagnostic mode.
Press
M until the desired diagnostic parameter appears:
Sensor Name and Raw Sensor Readings
If a sensor is programmed and is properly installed, the sensor name
should appear. If the sensor name does not appear, then the sensor
may be improperly programmed or defective. The raw sensor reading
is the uncalibrated output for each sensor. When fresh air is applied,
the raw sensor readings should be 200 to 700 for toxic gas and VOC
sensors; 100 to 1300 for the LEL sensor; and 1200 to 2300 for the
oxygen sensor. When calibration gas is applied, the raw sensor readings
should increase or decrease by the amounts listed in Technical Note -
123 Special Diagnostic Modes. If the raw sensor readings are outside
the normal range or do not change when gas is applied, the sensor or
monitor may be defective.
RF Test (Radio Frequency)
This feature applies when the monitor is used with the RAELink Remote
package. The RF test shows the successful rate of communication.
Adjust Lamp Failure Threshold
If the lamp physically appears fine, but the “Lamp” error message
appears during normal operation, the lamp failure threshold may be set
too high.
