such that the pack/product breaks the beam before
reaching the reject device. The beam may be positioned
either side of the detector. Ensure the sensors do not
effect the operation of the metal detector itself by
infringing the metal free zone limitations.
At line speeds of 61m/min (200ft/min) or greater the
sensors must not be positioned too close to the reject
device, ensure a minimum distance of 0.5m (1.5ft).
Adjust the height and alignment of the sensors so that all
packs break the beam at the same leading edge position
irrespective of the type or size of pack.
Electrical Connections (Photo-Sensors)
Electrical connections from the sensor should be
connected to the metal detector power supply
unit.
See ’Power Unit Electrical Connections’ in the Installation
section. Connect the sensor to the terminals labelled
Pack Sensor.
Setting Up Timer Type tm2fG] in Gated Mode
To set up the timer use the following procedure:
1) Prepare a sample pack containing a small metal
contaminant positioned at the rear/trailing edge
2) Enter the Engineers access code
Press the ’Enter’ key to store the settings in memory.
3) Pass the sample pack containing the small metal
contamination through the detector and adjust the
sensitivity so that the bar graph indicates 2
to 3 red bars
4) Press ’ETC’ soft key the display reads.
Select Timer A/B/C
5) Select timer A B or C, display now reads
Timer ’x’ Update Yes / No
Note:– ’x’represents the selected timer A, 8 or C
6) Select ’Yes’ display now reads
Timer type tm1/tm2(G)/tm3(G
7) Select ’tm2(G)’ if previously set to gated mode
display will read
Gated Timer Still Required Yes/No
If not set previously to gated mode, display will be as
shown in 8)
8) Select ’No’, display now reads:
Signal Delay # # # #sec
Reject Time # # # #sec
8) Place the sample pack with metal contaminant in
the rear/trailing edge (must be correct size sample) on
conveyor belt and allow it to pass through the detector
without skewing or slippage.
Press the ’signal delay’ soft key and adjust the signal
delay time so that the reject mechanism operates just as
the front/leading edge of the pack reaches the centre of
the reject device.
10) Pass the pack along the conveyor, and through the
detector as before.
Press the ’Reject Time’ soft key and adjust the reject time
so the reject device responds in a way which would reject
the pack if it were positioned correctly. We are not
attempting to reject the pack at this stage.
11) Press ’Enter’ key again, display now reads Tm2(G)
Gated Yes/No
12) Select ’Yes’ display now reads
Sync Delay # # # #sec
Window Time ####sec
Etc
NOTE:-
a) Always set the window time first.
