Operational Characteristics
Configuration of the Gas Transmitter via Magnetic Pin
A magnetic pin can be used to change the settings of the Dräger PIR 3000 infrared
gas transmitter (see "Accessories/Spare parts" on page 27) as follows:
— Automatic zerosetting.
— Manual zero calibration of the output signal.
1)
— Manual span calibration of the output signal.
1)
— Checking the signal transmission, check the alarm trigger and displaying the gas
category.
1)
— Changing the gas category.
1)
Automatic Zerosetting
 Deactivate alarm activation of the central device.
 Expose the gas transmitter to nitrogen, synthetic air, and/or fresh air via
calibration adapter and wait until measurement value stabilises.
 Place the magnetic pin onto the transmitter surface area marked by the " "
icon and hold it there (within the black frame) for at least five seconds. After five
seconds, the output signal of the gas transmitter switches to the display of the
span gas signal (3 mA) for as long as the magnetic pin is held against it. At the
same time, a zerosetting of the optical measuring unit is carried out
automatically.
 Remove the magnetic pin. After 30 seconds, the device exits the automatic
zerosetting routine. As confirmation of the automatic zerosetting, the output
signal changes back to the span gas signal (3 mA). This signal is indicated for
the same period of time as when starting the automatic zerosetting routine.
 Activate alarm activation of the central device.
1) A second person is required as helper for these tasks.
