Installation Procedure
Mounting
1. Thread the sensor into a suitable bracket or housing with the
Sensing Surface aimed toward the Target.
2. Set the Air Gap (shortest distance from Target to Sensing
Surface) at a typical distance of .020" to .040" (0.5 to 1.0mm).
Be sure to account for any eccentricity of the Target to avoid
damage to the sensor which can affect safety. This distance
should be >.010" (0.25mm) over the eccentricity of the Target.
NOTE: Rotate the alignment mark to point at the gear for Dual
Output and Directional Sensor Types.
3. Securely lock the sensor at the correct Air Gap using a jam
nut or other suitable means.
Do not over torque the mounting
thread.
Recommended tightening torque is listed below.
4.
A poured conduit seal must be applied within 18 inches
(0.45m) of the sensor.
Wiring
The wiring is provided as either shielded cable or individual leads.
Make all wire connections before applying power to the circuit.
The appropriate DC (direct current) power supply for each Sensor
Type is detailed on the XP2 Bulletin and marked on each sensor.
The wiring shall be mechanically protected as required by the
applicable area electrical code and shall be terminated in a
suitable terminal or junction facility.
Control Equipment connected to this equipment must not use or
generate more than 250V.
Wire Color codes are as follows:
Red
-
+ Power, DC Voltage positive
Black -
– Common, DC Voltage negative
White -
Signal A output, referenced from Common
Green -
Internal Housing Ground (connect to earth)
Bare
-
Cable shield (connect to instrument ground)
Yellow -
Signal B output, as applicable
Blue
-
Direction Signal output, as applicable
Cable and individual leads temperature range is -55°C to +200°C.
Earthing / Grounding
The green (or green with yellow stripe) wire of the sensor is an
internal connection to the metal housing. This wire
must be
connected to an earth ground
to maintain the safety of the
sensor. Additionally, no external ground is provided so the sensor
must be mounted as part of a bonded structure.
