Service
constant-current signal conditioners or other approved constant-current sources. The power supply consists of a
current-regulated, 2-20 mA at 18 to 28 VDC source. This power is regulated by a current-limiting circuit, which
provides the constant-current excitation required for proper operation of ICP
In general, battery-powered devices offer versatility for portable, low-noise measurements, whereas line-powered
units provide the capability for continuous monitoring. Consult the Vibration Division's product catalog for more
information about signal conditioners.
NOTE: Under no circumstances should a voltage be supplied to an ICP
diode or equivalent electrical circuit. This may include ohmmeters, multi-meters and continuity testers.
Safe Use
After completing the system setup, switch on the signal conditioner and allow 1 to 2 minutes for the system to
stabilize. The meter (or LED) on the signal conditioner should be reading "green." This indicates proper operation
and you may begin taking measurements. If a faulty condition is indicated (red or yellow reading), first check all
system connections, then check the functionality of the cable and signal conditioner. If the system still does not
operate properly, consult a PCB factory representative.
NOTE: Always operate the accelerometer within the limitations listed on the enclosed Specification Sheet.
Operating the device outside these parameters can cause temporary or permanent damage to the sensor.
Assembling
The EX604XYYY Series have hermetically sealed stainless Steel housings, with a glass-sealed connector, and do not
require any assembly. Only mounting to the machine being monitored using standard mounting accessories.
Dismantling
Other than removal from the mounting, there is no disassembly of the sensor required to take it out of service.
Maintenance
Routine maintenance, such as the cleaning of electrical connectors, housings, and mounting surfaces with solutions
and techniques that will not harm the physical material of construction, is acceptable.
®
sensors require constant current excitation for proper operation. For this reason, use only PCB
