9 Appendix
The software update set consists of:
–
EPROM for main processor “H”
– EPROM for watchdog processor “U”
– EPROM for communication “B”
– EEPROM for watchdog processor
– memory extension
In principle you should always pay attention to the direction of the notches before exchanging.
The notches show towards the PE connection.
Remove old EPROMS carefully out of their sockets and insert new EPROMS in the correct
position. Make sure that all pins are correctly seated in the sockets.
Insert the memory extension:
Exchange the memory extension against the EEPROM of the main processor. The plug direc-
tion of the memory extension is clear.
Assembly:
Connect the PE-wire.
Insert the base board.
Replace the electronic boards in the housing.
Connect the PE-wire from the cover.
Attach and screw on the side cover
Replace ETAMATIC in the control cabinet and connect it again.
Restore dataset!
Before continuing, restore the protected dataset.
Commissioning:
After you have replaced the old EPROMs and switched on the controller, the fault message
“U106" may occur at first. This fault is related to the parameters 937 to 976. Set these param-
eters to their default settings to clear this fault according to the instructions of the manual. Fur-
thermore check and change the following parameters.
You need a password for release level 4 to set these parameters. Ask LAMTEC for the re-
quired password. To get this password, send the device’s serial number by phone or fax. Due
to the EPROM replacement the CRC 4-check sum changes. Correct the CRC 4 check sum,
the existing software version and the writing on the configuration able beside your device! Fi-
nally tell LAMTEC the new calculated CRC 4 check sum, that LAMTEC can update the CV of
the device. Note that the internal firing-rate controller of software version A4a300 has a new
design, therefor it is required, to adjust Parameter 805 and 808 (depending on the software
version of your device).
