PREVENTIVE MAINTENANCE SCHEDULE

SECTION 7 - MAINTENANCE

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. Failure to follow this warning can lead to unsafe condi-
tions that can injure personnel and damage equipment.
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 PTSD Platinum Standard Smart
•
Pressure Transmitter and associated equipment and have
experience working with process control systems.
The Type PTSD 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 PTSD 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
MAINTENANCE PROCEDURES.
If the transmitter is inoperative, or if operation is faulty, refer
to Section 6.
