Chapter 5: Configuration Mode
Overview
This chapter describes how to view and change M2A parameters using Configuration Mode. It is accessed using
the program buttons.
Configuration Mode includes a 5-minute time-out feature. If you do not press a control button for 5 minutes, the
M2A automatically returns to normal operation.
NOTE:
If the M2A returns to normal operation because of a time-out, it enters a warm-up period just as it
does when it is first turned on.
If you are installing a new M2A, it has been setup at the factory. Use Configuration Mode only if you
want to change the M2A’s setup. If you want to change the detector type see “Chapter 6: Gas Type
Mode” on page 30.
Viewing & Changing M2A Parameters
1. While in normal operation, simultaneously press and hold the UP/YES and ENTER buttons for 5 seconds to
enter Configuration Mode. Release the buttons when the following screen appears.
2. If you want to exit Configuration Mode, press and release the DOWN/NO button and the M2A will return to
normal operation.
If you want to continue in Configuration Mode, press and release the UP/YES button. The target gas and the
full scale will be displayed for a few seconds before the first adjustable parameter, the alarm 1 setpoint, is
displayed.
3. If you want to change the currently displayed parameter, use the UP/YES and DOWN/NO buttons to adjust
it to the desired setting, then press ENTER to continue to the next parameter.
If the currently displayed parameter is OK, press the ENTER button to proceed to the next parameter.
Table 5 lists the M2A parameters you can set. Table 5 also lists the factory set value for each parameter.
