Maintaining Your Detector (2)

In the last section, we reviewed some of the most basic operating tasks that will ensure the GasAlertMicro 5 will operate normally in hazardous environments. We will continue with these recommendations in the form of a general summary. You can always refer to the maintenance section of the owner's manual for a more detailed description.

Replacing the Batteries

You will need to refer to figure 13 and table 18 on page 74 of your owner's manual to observe illustrations of how this task is performed. These instructions are only for the Alkaline Battery Pack (M5-BAT0501). First, open the latch (M5-BL-1) that can be found on the bottom of the unit. Remove the pack by lifting out bottom-first and away from the detector. You will not two captive screws on the pack. Remove these with a screwdriver. Then, take the battery shell away from the tray. Remove and replace the three batteries. Recall that these batteries must ONLY be those recommended by BW Technologies by Honeywell. Replace the cover and the screws. Finally, reinsert the battery pack and close the latch on the bottom. The same technique can be used for a lithium battery pack (M5-BAT08), but recall that it will be the entire pack that needs to be replaced as opposed to individual alkaline batteries. Refer to figure 14 in the owner's manual for a graphical overview of how this is accomplished.

There are other sections that are extremely worthwhile to read and understand. These can all be found in the owner's manual. For example, you will find an overview of how to replace a sensor or a sensor filter on page 76. You can discover how to clean or replace a lamp in the device that is known as a PID detector (photo ionization detector)(SR-Q07). You will learn how to replace a part known as the electrode stack and finally, you will be presented with a thorough troubleshooting guide. Remember that the PID sensor can only be added to the GasAlertMicro 5 PID version.

Again, recall that all of these sections serve merely to clarify and/or reiterate the instructions that are found in your owner's manual. All graphical illustrations and step by step instructions will likewise be found there. Regular maintenance of your device will not only allow it to last significantly longer in challenging environments, but these practices will protect you and your coworkers from potentially grave atmospheric situations.

Troubleshooting

Beginning on page 78, you will find a troubleshooting table that can be used to diagnose many malfunctions. It will cover such topics as the unit not activating, the detector immediately entering into alarm mode, a self test failing, inaccurate gaseous measurements and poor (or no) push button response. Even if there are no problems, it is wise to become familiar with this section, for it will also reinforce many of the topics that we have previously covered.

Finally, recall that in the event of an unforeseen error or if you have any questions that have not been covered in the previous sections, you may also contact BW Technologies by Honeywell directly. This is also useful if you wish to order spare parts or extra accessories. Feel free to use this supplement as an addition to your owner's manual at any time.
