PCB Piezotronics IMI SENSORS ICP EX604 Series Installation And Operating Manual page 23

Servicing
Due to the sophisticated nature of the sensors and associated instrumentation provided by PCB Piezotronics, user
servicing or repair is not recommended and, if attempted, may void the factory warranty. However, routine
calibration of sensors and associated instrumentation is recommended as this helps build confidence in
measurement accuracy and acquired data over time.
Repair
In the event that equipment becomes damaged or ceases to operate, arrangements should be made to return the
equipment to PCB Piezotronics for repair. User servicing or repair is not recommended and, if attempted, may void
the factory warranty.
Installation
Overview: Sensor must be mounted in order to be put into service. When choosing a mounting method, consider
closely both the advantages and disadvantages of each technique. Characteristics like location, ruggedness, amplitude
range, accessibility, temperature, and portability are extremely critical. However, the most important and often
overlooked consideration is the effect the mounting technique has on the high-frequency performance of the
accelerometer. Mounting methods include: Stud mount, adhesive mount, magnetic mount, or probe tip mount.
Cabling: Care and attention to cable installation and cable condition is essential as the reliability and accuracy of any
measurement system is no better than that of its weakest link. Due to the nature of vibration measurements, all sensor
cables will ultimately fatigue and fail. Good installation practice will extend the life of a cable, however, it is highly
recommended to keep spare cables on hand to enable continuation of the test in the event of a cable failure.
Adjustment
The sensor is a sealed device and no user adjustments are possible. However, routine calibration of sensors by the
manufacturer is recommended as this helps build confidence in measurement accuracy and acquired data.

Danger Areas (for
pressure-relief
devices)
Training
Industrial sensors to be installed in Hazardous Locations must have this done by trained professionals according to
Instructions
EN/IEC 60079-14 requirements.
Ex ic is "intrinsic safety", which limits the energy of sparks and surface temperatures to safe levels.
Details on Safety
of Protection
Ex nA is "Non-Sparking", which ensures that there is no risk of arcing and sparking or hot surfaces during normal
Category
operation with a minimum IP protection of IP54. (Only applies to connector version).

Special Conditions
Version Ex ic:
of Use
The apparatus must only be connected to a certified associated intrinsically safe equipment. This combination
must be compatible regarding intrinsic safety rules (see electrical parameters). The apparatus shall be connected
according to drawing 68438 (page 1/2)
The Integral Cable version has a maximum cable length of 327' according to the drawing 68438 (page 1/2)
Device complies with the requirements of the dielectric test per clause 6.3.13 of standard IEC 60079-11.
Version Ex nA:
The apparatus must be only connect to an equipment whose electrical parameters are compatible with the
electrical parameters. The apparatus shall be connected according to drawing 68438 (page 2/2). The connected
cable and the connector must provide a minimum ingress protection of IP54, when assessed according to IEC
60079-0 and IEC 60079-15. Unused connector must be fitted with an appropriately rated blanking cover.
