5.13.4 Replacing the Master Controller Board
In the unlikely event that the Master Controller Board needs to be replaced, there
are two possible scenarios:
a. Replacement using EEPROM U39 from the old board. This procedure should
be tried first.
b. Replacement when using a New EEPROM U39.
In either case, the Firmware IC’s U18 and U28 will have to be transferred from the
old board or be replaced with new. EEPROM U39 contains all of the configuration
and calibration settings for the transmitter including configuration, software
calibration settings, power levels and fault limits etc.
5.13.4.1 Replacement Using EEPROM U39 From Old Board
If the Master Controller needs to be replaced, but EEPROM U39 can be swapped
from the old board, then proceed as follows:
STEP 1 Shut the transmitter off and remove AC power from the transmitter.
STEP 2 Remove the defective Master Controller Board.
STEP 3 Carefully remove U39 from the new Master Controller Board and
replace with the EEPROM from the defective Master.
STEP 4 To transfer the Firmware IC’s from the old board to the new one or to
simply install new firmware refer to "5.15 Removing/Replacing
Firmware ICs" on page 5-24, then return here.
STEP 5 Set all dip switches on the new board according to the list below.
Typical settings are:
•S1-1 thru S1-4 - Customer set RS232 ID
•S1-5 ON for U39 model 25040 and Firmware part # 917-2435-203,
revision “AA” or later Master Controller code (S1-5 set to OFF
for use with U39 model 25C04 and any part number firmware).
•S1-6 thru S1-8 OFF (Factory use only)
•S1-9 OFF (ON = Microcontroller RESET)
•S1-10 ON (APC ON)
STEP 6 Install the new Master Controller Board and apply AC power to the
transmitter. It is a good idea to verify the transmitter configuration
settings in the Diagnostics Display.
NOTE:
To verify the most important configuration parameters, follow the steps listed
under "5.14.1 Configuration" on page 5-22, before continuing.
