Overview
This chapter describes use of the Calibration Program and corrective maintenance
procedures for the Beacon 100. It includes a troubleshooting guide for problems you may
encounter with the Beacon 100. Procedures to replace components of the Beacon 100 are at
the end of this chapter.
Calibration Program
The Calibration Program is used to calibrate the detector head installed on the Beacon 100.
The Beacon 100 supports either a direct connect (internal amp) or 4-20 mA transmitter
(remote amp) detector head.
• Direct connect detector head.
If a direct connect detector head is installed, then all calibration adjustments are made
at the Beacon 100 after calibration gas is applied to the detector. When a direct connect
detector head is installed, the detector head may be installed at a remote location, or a
detector may be installed directly to the Beacon 100 in one of the conduit hubs on the
bottom.
• 4-20 mA transmitter detector head.
If a 4-20 mA transmitter detector head is installed, then all calibration adjustments are
made at the detector head after calibration gas is applied to the detector. A 4 - 20 mA
transmitter detector head is installed remotely from the Beacon 100.
WARNING: The Beacon 100 is not an active gas monitoring device during the
calibration procedure.
Entering the Calibration Program
1. Assemble the calibration kit. See the operator’s manual for the installed detector head
for calibration procedures specific to that detector head.
2. Open the Beacon 100 housing door and locate the program buttons below the display
screen.
3. Press ESCAPE and DOWN buttons simultaneously and hold for 3 seconds to enter
the Instrument Setup Program.
The display screen changes from the gas reading to a screen that gives you a choice of
CALIB or ALARMS & MISC.
