10. While in Configuration Mode press and release the ENTER button to accept the
displayed parameter setting and move to the next one. Use the UP/YES and DOWN/
NO buttons to adjust a setting. See “Chapter 5: Configuration Mode” on page 26 for a
complete description of Configuration Mode.
11. When you have reviewed and accepted the last item in Configuration Mode by
pressing the ENTER button, display will ask SAVE IT? YES/NO.
12. To save the configuration settings, press and release the UP/YES button.The display
will indicate Config Saved and the Beacon 110 will begin its warm-up sequence.
To discard the settings and review them again, press the DOWN/NO button. The
display will ask DO OVER? YES/NO. Press the UP/YES button and the display will
indicate Re-do Config, then display the target gas and the detection range for a few
seconds before returning to Configuration Mode. Repeat steps 6 - 8 until the settings
are as desired.
13. After the Beacon 110 completes its warm-up sequence, the display will indicate CAL
NEEDED, the buzzer will sound a steady tone, the strobe (if installed) will flash, the
fail relay will activate, and the fail LED will turn on. Since the input type and/or gas
type has been changed, a successful calibration must be performed before the
Beacon 110 can enter normal operation.
NOTE: If the input type was set as 4 - 20 mA, the Beacon 110 will enter normal
operation since calibration is done at the detector for a 4 - 20 mA type input.
14. Press and release the UP/YES button to enter Calibration Mode. Normally, you must
hold the UP/YES button for 5 seconds to enter Calibration Mode, but since a
calibration is required, only a momentary push is needed to enter Calibration Mode
after changing the gas type.
15. See “Calibration Mode” on page 33 for calibration instructions.
NOTE: When calibrating a Beacon 110 after changing the gas type, the Beacon 110
will not ask if you want to calibrate, or whether you want to perform a fresh air
adjustment, span adjustment or zero adjustment. Since a complete calibration
is required, the calibration sequence will proceed without asking if you want to
perform certain operations.
