Installation
Environment
Milltronics Millpulse 600 should be mounted in an area that is within the temperature
range specified and that is suitable to the housing rating and materials. The cap should
be accessible to allow for wiring and viewing if the status display LED is used.
Milltronics Millpulse 600 should be mounted using the supplied mounting flange, onto a
vibration-free structure. The gap between the face of the Milltronics Millpulse 600 and
the target should be sufficient so there is no danger of the target damaging the unit. Refer
to the chart in the
Operation section (page 8) for the maximum allowable gap with
respect to target velocity.
Wiring
Where possible, the probe should be mounted such that the conduit entry is pointing
down to avoid accumulation of condensation in the casing. Where wiring must be run in
conduit, the use of flexible conduit is suggested for easier removal or adjustment of the
probe.
It is advisable to keep the Milltronics Millpulse 600 away from high voltage or current
runs, contactors and SCR drives.
Ensure that the switching current of the PLC input is above the residual current of the
Milltronics Millpulse 600 and that the load resistance presented by the PLC input is low
enough to ensure that the minimum operating current of the Milltronics Millpulse 600 is
exceeded (see Loading graph). If your PLC does not meet the requirements, a resistor
across the PLC inputs can be used to increase the switching current.
WARNING: The probe is highly magnetic. Keep it away from
magnetosensitive materials such as computer discs and audio or
video tapes.
Note: In climates where direct sunlight may cause the Milltronics Millpulse 600
temperature to rise above the specified limit, shade the unit by installing a sun shield.
Note: All wiring must be done by qualified personnel in accordance with all
governing regulations.
WARNING: Do not connect Milltronics Millpulse 600 directly to
supply.
Note:
• The protective earth terminal indicated by must be connected to reliable
ground.
