WARNING: Disconnect primary power prior to servicing.
Maintenance and Alignment
NOTE:
To verify the most important configuration parameters, follow the steps listed
under “Configuration,” later in this section, before continuing.
STEP 8 Turn the transmitter on and check the calibration. If the transmitter
calibration and configuration seem to be okay, then this procedure is
finished. If it did not work, then try the Recall Settings function in
the Diagnostics Display. If it is still not working, then U39 will have
to be replaced using the procedure below “Replacing EEPROM
U39”.
5.13.5 Replacing EEPROM U39
If it is necessary to replace EEPROM U39, with the old Master Controller or with a
new Master Controller, the “System Configuration and Calibration” procedure will
have to be performed. However, since a new EEPROM is being installed a few
preliminary steps will have to be done first.
!
WARNING:
BE SURE TO USE AN ANTI-STATIC WRIST STRAP WHEN HANDLING PC
BOARDS OR IC’S TO PREVENT DAMAGE TO THE COMPONENTS.
STEP 1
Shut the transmitter off and remove AC power from the transmitter.
STEP 2 Remove the Master Controller Board. If only the EEPROM U39 is
being replaced then replace U39 with the new one, reinstall the
Master Controller Board and skip to Step 6. If the Master Controller
and/or the firmware is also being replaced then proceed with the next
step.
STEP 3 Install the new U39 in the new Master Controller Board
STEP 4 To transfer the Firmware IC’s from the old board to the new one or to
simply install new firmware refer to “Removing and Replacing
Firmware ICs” later in this section, then return here.
STEP 5 Set all dip switches on the new board according to the listing below
and install the Master Controller Board. Typical settings are:
•S1-1 through S1-4 - Customer set RS232 ID
•S1-5 ON for U39 model 25040 and Firmware part # 917-2435-206
or 917-2435-207 for the Z2R, revision “AA” or later Master Con-
troller code. (S1-5 set to OFF for use with U39 model 25C04 and
any part number firmware).
•S1-6 through S1-8 OFF (Factory use only)
