Chapter 7: Maintenance Overview This chapter describes how to calibrate the Beacon 110 using Calibration Mode, replace the AC fuses, and preventive maintenance procedures for the Beacon 110. It includes a troubleshooting guide for problems you may encounter with the Beacon 110. Calibration Frequency Although there is no particular calibration frequency that is correct for all applications, a calibration frequency of every 3 to 6 months is adequate for most Beacon 110 applications.
When calibration gas is applied to the Beacon 110 during a span (zero for an oxygen detector) adjustment, the Beacon 110 will freeze the display reading at the highest (lowest for an oxygen detector) response to the calibration gas. The calibration gas can then be removed and the Beacon 110 will continue to display this reading and retain it in its memory until the span (zero for an oxygen detector) adjustment procedure is completed.
No Normal Operation Press UP/YES Calibrate? Yes/No Yes Calibrate at Detector Head Press ENTER When Done Figure 13: 4 - 20 mA Transmitter Detector Head Entering Calibration Mode WARNING: The Beacon 110 is not an active gas monitoring device during the calibration procedure. The 4-20 mA output signal will “freeze” at 3.5 mA (17.4 mA if an oxygen detector head is installed) and all relays will remain in their non-alarm state while the Beacon 110 is in Calibration Mode.
Calibrating a 4 - 20 mA Detector Head If a 4-20 mA detector head is installed on the Beacon 110, proceed as follows: 1. The display will be alternating between CAL AT AMP and the current gas reading as described above. 2. Verify that the detector head is in a fresh-air environment. (If necessary, use a zeroemission air cylinder, also known as zero air, to introduce a fresh-air sample when adjusting the fresh air reading below.) 3.
4. If you want to skip adjusting the span (zero for an oxygen detector head) setting, press and release the DOWN/NO button. The display will indicate Leaving Cal Mode and the Beacon 110 will return to normal operation. If you want to continue with adjusting the span setting, press and release the UP/YES button. APPLY will alternate with SPAN Gas (ZERO Gas for an oxygen detector head) on the top display line and the current gas reading will be on the bottom display line. 5.
Replacing the Fuses The Beacon 110 has two replaceable AC fuses. NOTE: To replace other components of the Beacon 110, contact RKI Instruments, Inc. for further information. 1. Turn off or unplug all incoming power to the Beacon 110. 2. Open the housing door of the Beacon 110, then place the power switch in the OFF position. 3.
