Filter Resistor Pack; Hardware Cold Starting - Loma IQ2 Service Manual

7. Undo and remove the 10 M3 pillars that secure the control board into the
control box.
8. Ensure all removed fixings are retained.
9. Carefully remove the board.
10. Replacing the control board with your new board is the reverse of its removal.
The new board will come pre-programmed with the current revision of operating
software only.
1. Check all fitted link positions on the new board match those of the removed board.
2. Fit the filter resistor pack from the old board.
3. Refit any optional items removed from the old board. Before fitting the reports/logs
option integrated circuit ensure the legs of the chip are straight and correctly
formed to ensure positive location into its base. Only proprietary tools should be
used to minimise the risk of damage. Failure to observe this simple preparation
may result in a poor insertion into the base. This could result in permanent
damage to the device and/or operational failure of the detector.
4. The new board will require configuring with all search head set up data and all
applicable product data. Guidance in configuring the search head is given in the
"Configuration and Set up Information"
a hardware "Cold Start" be performed to ensure the detector settings are returned
to their default values before commencing any data re-entry. Refer to
Cold Starting"

FILTER RESISTOR PACK

The filter resistor pack is not polarised; therefore it does not matter which way
round it is fitted.
If the transport speed has been changed, then the new speed must be entered
into the "Belt Speed"

check if a change to the fitted filter resistors is required.

HARDWARE COLD STARTING

Performing a cold start erases all stored set up and product data and returns to
set up default values. Once completed the detector will require re-configuring as
described in the
Setup section of this manual together with the re-entry of all product related
data.
To force a hardware cold start the following sequence of events must be
followed.
