Description
Allows the user to select the tracker option for each of the products as
required. See Appendix C – Product signal tracking menu, page 147.
Allows the user to make manual adjustments to the calibration of the unit via
the Manual setup menu.
The relay marked Attention on the power relay PCB has two different
functions: select Run, in order that the relay is energised whenever the
detector is in run, ie it is looking for metal; select ERROR, in order that the
relay is energised when a run error occurs.
Allows the user to gain access to product F, either via the Change Product
or Product setup menus. See Appendix B – Commissioning Guide, page
140.
Turn this to ON if no product is to be allowed down the line without being
checked for metal. This makes it impossible to disable the reject mechanism
via the disable reject menu and in addition, provided a photo-eye is fitted to
the system, that product will be rejected during a full calibration cycle.
Turn this facility on if product calibration is to be initiated after the signal
level exceeds a preset value (set by Trigger thrsh in the Manual setup
menu). Only appears if no photo-eye is used or if FRUN (free run) speed
mode is selected in the Configuration menu.
Set to YES to enable dual frequency operation, when using a dual frequency
detector.
The relay marked RUN on the microprocessor control PCB has three
different functions:
• Select IN RUN, in order that the relay is energised whenever the
detector is in run, ie it is looking for metal;
• Select REJECT, in order that the relay is energised when a reject
occurs (in addition to the REJECT relay).
• Select DUAL when set to Dual frequency mode, to switch from high
to low frequency (only appears when Dual frequency is set to YES).
