Options
ENGLISH (default entry), FRANÇAIS, NEDERL, DEUTSCH, ESPAÑOL,
ITALIAN, PORTUGES, KATAKANA.
CONVEYOR, FREEFALL, PIPELINE or PHARM.
METRIC or IMPERIAL.
Select YES if a photo-eye has been wired to the control board.
Select YES if a blocked or disconnected photo eye is to cause a System
fault to be generated, or NO if a Run error is to be generated
Enter the coil gap as shown on the machine details plate (inside control box)
or from the table in your Service Manual.
This entry will appear, if a value must be entered. The PEC length is the
distance from the centre line of the photo-eye to the leading face of the
detector plus the Rx distance (again shown on the machine details plate).
This entry will appear if speed mode is set to FRUN. Enter the filter resistor
value as fitted on the main control board.
Select FIXED, unless your system is vari-speed or free running. For variable
speed system select VBLE, and for free-running FRUN.
This entry will appear if speed mode is set to FRUN. Enter YES for a
catalogue Freefall unit, otherwise NO.
This entry will appear if speed mode is set to FIXED. Enter the belt speed.
This entry will appear if speed mode is set to VBLE. Enter the CTB constant.
This entry will appear if speed mode is set to VBLE. Enter YES to log speed
too fast or too slow Run errors. Limits are determined by coil gap and filter
resistance.
Select the required level of tolerance to be adopted during auto-calibration.
The higher the setting the more sensitive the detector, but the more prone it
will be to false rejects if the product effect varies (phase dispersion). We
recommend LOW for most applications.
Select the desired auto-calibration period: Short, Long or Extra Long.
Short is recommended for most applications, provided that at least eight
packs can be passed during a calibration cycle.
