WeighTech MicroWeigh Standard Checkweigher Product Manual page 19

Zero opto Select the operating mode for the first opto sensor. If the sensor is light acti-
vated (normally open), select std mode. If the sensor is dark activated (normally
closed), select rev mode. It is recommended to use std mode with the Banner opto
sensors black wire output. The zero opto sensor detects if products are too close
to be accurately weighed and completes the autozero cycle.
Weigh opto Select the operating mode for the second opto sensor. If the sensor is
light activated (normally open), select std mode. If the sensor is dark activated
(normally closed), select rev mode. It is recommended to use std mode with
the Banner opto sensors black wire output. The weigh opto sensor detects the
products as they transition off the weighbridge.
Sensor mon When set to "On", the system will watch for items being detected by only
one of the optical sensors. If more than twenty consecutive items are missed
by one of the optical sensors a warning message will appear on the display
(either "Check Weigh Opto" or "Check Zero Opto"). The warning message will
automatically clear as soon as the failing sensor detects an item. Set to "Off" to
disable this warning system completely. (The system can run without the zero
opto sensor, but "Autozero" and "Sensor mon" must be disabled and items that
are too close to weigh accurately will not be detected. This is a degraded mode of
operation.)
Close cnt Number of ticks from zero opto beam until weighbridge. Increasing this
setting allows the machine to be more forgiving of closely spaced items.
Wbrdg ticks Number of ticks required to travel from the zero opto beam to the weigh
opto beam. This setting is used to determine if more than one piece is on the
weighbridge, which would cause a too close to weigh error. Set to 0 to disable
and use the old style too close detection. (Old style detects an item as too close if
the zero opto beam is blocked when the item hits the weigh opto beam.) If this
setting is not zero, Dynacal will automatically measure the distance between the
beams and update this setting.
Eye space Distance between the leading zero beam and the trailing weigh beam, in
inches. Used to scale the displayed data in the packaging menu.
Travel Controls the front panel LEDs to indicate the status of the weigh and zero
beams–a useful diagnostic tool, but it doesn't have any effect on the operation
of the machine. Set to correspond to the direction of item travel, as seen when
you're viewing the front panel of the indicator. When set to "L-R", blocking the
zero beam (at the front edge of the weighbridge) will illuminate the Motion LED
on the front panel of the indicator, and blocking the weigh beam (at the trailing
edge of the weighbridge) will illuminate the Net LED on the front panel. When
set to "R-L", the zero beam will light the Net LED, and the weigh beam will light
the Motion LED. If you set the wrong, nothing bad will happen.
Dbase On/Off. When on, the indicator will record and transmit each item weight to the
Palm. Handy for troubleshooting purposes.
