Introduction
The SLIPSWITCH series is designed to detect slippage or
stoppage on elevators, conveyors, fans etc.
The units require no connection with the shaft, have no
moving parts and a virtually unlimited life. They incorporate
microcontroller circuitry which automatically calibrates to
20% under normal speed and provides a programmable 0-
30 second start up delay.
Installation
The Inductive sensor section detects a metal target on the
shaft. The target can be an existing bolt head or similar.
Ideally, the target should be of ferrous metal but non ferrous
metal will be detected at short range. Maximum range
ferrous/non-ferrous materials is 12/5mm with a 30mm
diameter circular target. Smaller targets may be used but
operating distance will be reduced.
The SLIPSWITCH should be mounted adjacent to the
target, ensuring that the distance to the target does not
exceed the stated maximum. When mounted against a solid
steel shaft, the target or bolt head should protrude from the
shaft at least 15mm, otherwise the sensor will not be able to
distinguish the target from the shaft and red input light would
stay on permanently.
Wiring to the SLIPSWITCH can be any length as required,
using ordinary unscreeened cable. However, if long cable
runs are to be used, the wiring should not be positioned
adjacent to cables carrying high voltage or current.
Two locknuts are provided to mount the units in position.
Mount securely to withstand vibration.Ensure that the unit
and target are adequately guarded.
Cabling
Connect the unit as shown in the connections diagram.
Commissioning & Auto-calibration.
Two LED's are provided for information purposes, on the
SLIPSWITCH. The input LED is red and flashes everytime
a target passes the face of the sensor. The output LED is
green. With normal running, the output LED is a static
green and the output is on (energised).
With an underspeed condition both the LED and output will
be off (de-energised). The SLIPSWITCH is factory set to a
speed of 10PPM and a start up time of 5 seconds. If the
time delay required is greater than 5 seconds, see
'Recalibration for a Different Setting', otherwise, proceed as
follows-
