5.1
Final positioning
The TR-NC8 transmitter is supplied already calibrated and complete with sensor and extension cable. Should the
sensor be replaced with one of the same type, the transmitter does not need to be recalibrated.
After positioning the sensor with the nominal air gap indicated (1.50 mm) and connecting it to the transmitter, the
sensor and the transmitter need to be fine-calibrated as follows:
• connect the transmitter power supply to the terminals indicated
• connect a voltmeter to the GAP+ and GAP- terminals
• move the sensor a bit at a time until reading 5VDC on the voltmeter and lock the sensor in this position.

General rules for proper electrical installation
The monitoring system, consisting of the sensor installed on-board the machine, the transmitter and the analogue
signal acquisition
system, has a low-voltage circuit which, coexisting with the power and drive circuits, may be affected by electro-
magnetic phenomena.
For this reason, the following installation rules need to be observed in order to prevent interference with the moni-
toring system.
5.2.1
Electrical cabinet
A system should have a dedicated cabinet for the power devices and one for the control devices.
