Pull out the circuit boards a bit, remove the PE-connection and take out the circuit boards
of the housing.
4. Remove the base board:
The base board is joined with the rear wall to one unit. You can be take it off simply from
the CPU board. Disconnect the PE-wire.
The EPROMs / EEPROM /memory extension are plugged on the CPU board.
5. Remove EPROM/EEPROM:
The software update set consists of:
NOTICE
Always pay attention to the direction of the notches before exchanging. The notches show to-
wards 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.
6. Insert the memory extension:
Exchange the memory extension against the EEPROM of the main processor. The plug
direction of the memory extension is clear.
7. 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.
8. Commissioning:
After you have replaced the old EPROMs and switched on the controller, the fault mes-
sage “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.
Check and change the following parameters :
EPROM for main processor „H“
EPROM for watchdog processor „U“
EPROM for communication „B“
EEPROM for watchdog processor
memory extension (from version 5.0003 on)
