same voltages as before, but at the wire ends , using the wire colors for terminal identification. If
the voltages are not correct, the cable is defective. Contact the Tecweigh Service or Parts
Departments (Section 2.01) for a replacement.
If the voltages are correct, reconnect the four wires (or the plug-in connector) to the SC PCB,
and measure the same voltages at the SC PCB
terminals.
If the voltages are not correct, the SC PCB is defective. If this occurs,
both the WP20 and SC
PCBs should be returned for servicing. Contact the Tecweigh Service or Parts Departments
(Section 2.01) for further instructions.
9.08 The Default Parameter (
setting all Parameters to their default values
)
If the WP20 does not respond to any commands and the firmware appears to be “scrambled” or
corrupt, re-setting the Parameter Table to its default values can be tried. The Default Parameter
only applies to the
Tecweigh MP200, MP300, and MP400 processors . This procedure should
only be done when the WP20 processor will not respond to any other commands
IMPORTANT NOTE: Before you default the processor, make sure that all current user
determined Parameters (recorded in the Parameter Table, Section 11.02, column 5) are
available, so they can be replaced in the WP20 processor after defaulting.
To perform the default procedure, hold the FUNCTION key in for 5 seconds. When the
“Simulation OFF” message appears, that is verification that the Parameter Table has been
accessed. Now hold in the DOWN ARROW key and simultaneously press the FUNCTION key
once. The message. “Params NO CHANGE” will appear. Now press the SELECT key once.
The message “NO CHANGE” will flash. Press the UP ARROW key twice and the flashing
“DEFAULTS” message appears. Press the SELECT key and it will stop flashing. Now hold in
the FUNCTION key for 5 seconds. The message “Simulation OFF” immediately appears and
then the message “defaults restored” will appear momentarily.
The processor has now been reset to its default values.
If the above default procedure did work, you will need to re-enter the previously saved
Parameters into the processor. Refer to Chapter 6.
If the above default procedure did not work, a “hard boot” can be tried. This is done by
removing the button battery from the board. Also remove any external power. Let it sit for about
one minute so all the capacitors discharge. This will clear the onboard RAM memory. After the
time has elapsed, replace the battery and re-apply power. The display ******** should appear
for a few seconds, and then move on to the general display. If this procedure works, the
previously saved parameters will need to re-entered into the processor. Refer to Chapter 6.
If neither of the above procedures worked, another Default procedure can be tried, but most
likely the processor is defective and needs to be returned for servicing. Contact the Tecweigh
Service or Parts Department (Section 2.01) for assistance.
