BASIC FAULT FINDING

1) Input light does not illuminate.

Check that you have a supply of the correct value across the brown and blue
wires. Slide a screwdriver blade across the face of the sensor, the input light
should flicker. If not, contact your supplier. If it does, move the front face nearer
the target and check target size is as specified under "Installation".

2) Input light stays on permanently.
Either increase the gap between the target and the shaft, or between the
target and the sensor face.

GUARANTEE

The equipment is covered by a 12 months guarantee from the date of shipment. Any faults
arising due to faulty materials or workmanship, within the guarantee period, will be corrected
free of charge providing the equipment is returned to us carriage paid.

GENERAL

The M800 motion monitor detects slip, low or zero speed on belt and bucket elevator legs, conveyors or
rotating machinery.
The unit requires no contact with the shaft, is fully solid state, and has a virtually unlimited operating life.
The M800 may be used either as a dual trip unit giving an alarm at 10% below set speed and a shutdown
signal at 20% below set speed, or a single trip giving a shutdown signal at 20%. With the addition of an
auxiliary relay, it can also give a shut down signal at 10% (see fig. 4).
An automatic calibration facility allows the unit to be programmed to give a start up delay of up to 30
seconds, whilst simultaneously calibrating for nominal speed.
An auxiliary pulse output is provided to feed suitable speed indicators.

INSTALLATION

The inductive sensing device, located in the front of the M800 enclosure is designed to detect a metal target
on a shaft. The target can be a bolt head or similar.
Ideally, the target should be a ferrous metal but non-ferrous metal will detect at a shorter range. Maximum
range for a ferrous material is 11/32" (9mm) and for non-ferrous metal is 7/32" (6mm), assuming a 3/4"
(19mm) diameter target. Smaller targets may be used but operating distance will be reduced.
The M800 should be mounted adjacent to the target, ensuring that the distance to the target does not exceed
the stated maximum. Typical mounting methods are shown in fig 1.
When mounted against a solid steel shaft, the target or bolt head should protrude from the shaft about 3/
8" (10mm). Otherwise the sensor will not be able to separate the target from the shaft and the red input
light would stay on permanently (instead of flickering) and it would not be possible to calibrate the unit.

TACHO OUTPUT

An opto-isolated output is provided, rated at 30V 100mA max. The output is on when the target is detected
and off otherwise. This output pulse can be used to feed remote tachos or other electronic products.

Mounting Procedure For Speedswitch M800 Motion Monitor

Fasten the Speedswitch to a suitable mounting bracket, with the nose of the switch within the

sensing range of the target., as shown below, and then wire up and calibrate as described in

Set-up procedure.

WIRING

The unit connections and typical wiring diagrams are given in figs. 2,3 4 and 5. Note that contacts are
voltage free and there is no connection between terminal 1 and the relay, until links are installed as
required. See figs. 2,3 and 4. Note that the startup is initiated by applying power

COMMISSIONING & AUTO-CALIBRATION

The M800 is factory calibrated at a set speed of 10 ppm and a start up delay of 5 seconds. For applications
requiring a different speed or delay, see initial Setting up Operation. For future re-calibration see
Re-Calibration for a Different Setting.

INITIAL CALIBRATION

If the start up delay required is less than 5 seconds (if longer, see re-calibration below).

1) Ensure that all connections are correct.

2) Apply power to the M800 and start machinery.

3) Allow the machine to reach nominal speed and then hold either end of the magnet (supplied) on the

CAL point on the label for the start up delay required then remove the magnet. The delay can be set
by counting flashes on the output LED while the magnet is on the CAL point. Each flash represents
1 second.

4) The output LED will flash to 'echo' back the set time and will automatically calibrate to 10% and 20%
below speed.

RE-CALIBRATION FOR A DIFFERENT SETTING

If the unit is to be calibrated to a higher speed and shorter time delay, follow the initial procedure detailed
above. If the speed is lower or the required delay longer, the M800 may cut out before the machine has
reached speed, in this case follow the procedure below:-

5) Hold one end of the magnet on the CAL point.

6) Switch on the M800 and machinery.

7) Allow the machinery to reach speed and remove the magnet.

8) Wait until the output light stops flashing and then calibrate as detailed under Initial Calibration 3&4.
