Restore Drive
The transmitter can drop into safe mode operation 100kHz at a low drive current. For example
the Drive On time of a particular operating frequency may have been manually increased
causing the current limit value to be exceeded.
Even when the on time may have been manually reduced from within this screen to a safe level
(usually less than 10) the transmitter will not automatically restart. Select this option to restart the
transmitter.
A restored drive will display a drive current that is greater than the safe mode value. If this is the
case it is recommended to start the auto configure process rather than attempt a manual on
time adjustment. If the drive does not restore then the transmitter may be in shutdown.
Remove the control box front panel then drop down the internal hinged main control board to
allow visual access to the left hand transmitter board. If the bottom red LED is illuminated then
the transmitter is in shutdown. If only the orange led is illuminated then the transmitter is still in
safe mode. In this case, try lowering the on time value a little more and perform another restore
drive.
If the red LED stays on then contact your local Loma service centre for assistance.
Auto Configure
Select this option to start the full setup process for all operating frequencies. The process
commences by resetting the on time values for each frequency to zero.
The configuration progress is displayed and will close automatically upon completion.
Configure current
This entry sets the target transmitter drive current that the auto configure process will use, subject
to a maximum figure of 350mA.
For conveyor detectors using the standard board, the default value is 230mA. For conveyor
detectors using the auto-balance board, the default value is 350mA.
