SECTION 15 - MAINTENANCE
INTRODUCTION
The reliability of any stand-alone product or
control system is affected by maintenance of
the equipment. ABB recommends that all
equipment users practice a preventive
maintenance program that will keep the
equipment operating at an optimum level.
Personnel performing preventive maintenance
should be familiar with the TB84PH Advantage
Series analyzer.
WARNING Allow only qualified personnel (refer to
INTENDED USER in SECTION 1 - INTRODUCTION) to
commission, operate, service or repair this
equipment. Failure to follow the procedures
described in this instruction or the
instructions provided with related equipment
can result in an unsafe condition that can
injure personnel and damage equipment.
PREVENTIVE MAINTENANCE
Table 15-1 is the preventive maintenance
schedule and check list for the TB84PH
Advantage Series analyzer. The table lists
the preventive maintenance tasks in groups
according to their specified maintenance
interval. The maintenance intervals are
recommendations and may vary depending on the
location environment and the process
application. As a minimum, these recommended
maintenance tasks should be performed during
an extended process shutdown. Tasks in Table
15-1 are self-explanatory. For sensor
cleaning procedures, refer to CLEANING THE
SENSOR.
