ECA 450 Maintenance

Instruction 0024-9400

4 Maintenance

Field maintenance of the ECA 450 is limited to the following:

• Battery charging

• Water Trap Filter replacement

• Printer Paper replacement

• Sensor replacement

• Cleaning the probe

• Resetting the microprocessor

• Replacing the internal particulate filter

All other maintenance should be performed by an authorized Bacharach

Service Center (Section 6.3).

4.1 Battery Charging

A fully charged battery pack will power the analyzer for a minimum of

8 hours. When the battery pack is just about depleted, the message “LOW

BATTERY” will appear at the bottom of the screen; after which, the analyzer

will operate from 5 to 15 minutes before automatically shutting itself off.

Recharge the analyzer’s internal battery pack by first plugging the supplied

AC adapter in a source of 100–240 VAC, 50/60 Hz power. A green LED on the

adapter should glow, indicating that it is operational. Then insert the

adapter’s output plug into the analyzer’s POWER connector (Figure 1-1).

A fully discharged battery pack should take approximately 11 hours to

recharge. Note that a protection circuit within the analyzer prevents the

battery pack from being over charged.

If the battery pack becomes depleted while the analyzer is being used, or if a

continuous run time of over 8 hours is required, then the AC adapter can be

used to both run the analyzer and charge the battery pack at the same time.
