SECTION 7 - MAINTENANCE
INTRODUCTION
The reliability of any stand-alone product or control system is
affected by the maintenance of the equipment. Bailey-Fischer
& Porter recommends that all equipment users practice a pre-
ventive maintenance program that will keep the equipment
operating at an optimum level.
NOTE: Refer to the
Installing a 4 to 20 mA Transmitter in a Haz-
ardous Location application guide when applicable.
Personnel performing preventive maintenance should meet the
following qualifications:
•
Be qualified electrical technicians or engineers that know
the proper use of test equipment.
•
Be familiar with the Type PTSDL Platinum Standard Smart
Level Transmitter and associated equipment and have
experience working with process control systems.
PREVENTIVE MAINTENANCE SCHEDULE
The Type PTSDL Transmitter has no moving parts and
requires limited maintenance when operated under normal
conditions.
Table 7-1 is the preventive maintenance schedule for the
Type PTSDL transmitter. The table lists the tasks in groups
according to their specified maintenance interval. Some tasks
in Table
7-1 are self-explanatory. Instructions for tasks that
require further explanation are covered under PREVENTIVE
MAINTENANCE PROCEDURES .
If the transmitter is inoperative, or if operation is faulty, refer
to
Section 6 .
WARNING
System maintenance must be performed only by qualified per-
sonnel and only after securing the equipment controlled by the
circuit. Altering or removing components from an active circuit
may upset the controlled process leading to personnel injury
and equipment damage.
Explosionproof/dust-ignitionproof installations and intrinsi-
cally safe installations in Class II or Class III hazardous loca-
tions require that the assembly be kept tight while circuits are
live unless the location is known to be nonhazardous at the
time.
