MC-III™ Panel Mount Flow Analyzer

Section 6

Section 6 - MC-III Panel Mount Maintenance

The MC-III™ Panel Mount is designed to provide many years of service with minimal maintenance. Batteries

require periodic replacement, and battery life depends on whether battery power is the primary or secondary

power source.

All configuration settings are stored in nonvolatile memory; therefore, configuration settings will not be lost

in the event of battery failure.
The circuit assembly may also require replacement over the life of the instrument. A replacement procedure is

provided in this section.

Lithium Battery Replacement

The MC-III Panel Mount uses a lithium battery with a life expectancy of approximately 2 years. Due to the

flat discharge characteristics of the lithium battery, it is difficult to determine how much life remains in a

battery at any given time. To preserve configuration and accumulated volume data, replace the battery at

2-year intervals.

The lithium battery that powers the MC-III Panel Mount is a sealed unit; however, should

a lithium battery develop a leak, toxic fumes could be emitted into the atmosphere.

Ensure that the instrument is in a well-ventilated area to avoid breathing fumes. Exercise

caution in handling and disposing of spent or damaged batteries. See additional informa-

tion on lithium batteries in

Appendix B

of this manual.

Important: Press the ENTER/SAVE key on the keypad before replacing the lithium battery to save

the accumulated total to nonvolatile memory. Once the battery is replaced and power is

restored to the unit, the last saved accumulated total will be displayed in the LCD.

The lithium battery is secured with a velcro strap to a metal plate, which is connected to the circuit board by

two standoffs. The battery is connected to the circuit assembly via connector J1.
To replace the battery, perform the following steps:
1. Disconnect the battery from the connector J1 on the circuit assembly.
2.

Using a flathead screwdriver, remove the two standoff screws connecting the metal plate and battery as

sembly to the circuit board. Loosen the velcro strap that secures the battery to the metal plate and remove

the battery (

Figure 6.1, page 88

). Send the depleted battery to a fully permitted Treatment, Storage and

Disposal Facility (TSDF) or to a permitted recycling/reclamation facility, as required by federal regula

tions (see

Appendix B

3. Install the new battery against the metal plate in the same position as the original battery, and secure the

velcro strap tightly around the battery.

4. With the metal plate positioned so that the battery is between the plate and the circuit board, realign the

screw holes in the plate with the standoffs, and replace the two screws that were removed in step 2.

5. Connect the new battery to the J1 connector on the circuit assembly.
