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: The Microphone System must be mounted on low profile stands and clamps in order to be
put into service. Characteristics like location, ruggedness, amplitude range, accessibility, temperature,
and portability are extremely critical. 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.
Install Microphone system per drawing 65241.
Adjustment
The EX378XYYY series come assembled in a system 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)
N/A – not a pressure relief device.
Training Instructions
Industrial sensors must be installed in Hazardous Locations by trained professionals according to
EN/IEC 60079-14 requirements.

Special Conditions of
Use
Version Ex ia :
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 65241.
The mounting of the apparatus into an installation must be carried out in such a way that sensor
metallic body and cable shield are reliably connected to the system earth.
For final installation, the user shall take all necessary precautions to maintain the minimum degree
of protection IP20 of the sensor connection when connected according to the requirements of
EN 60079-14 and IEC 60079-14 standards.
