10 CHANGES TO AN ALREADY OPERATING SYSTEM
This chapter looks at changes that may need to be made to an already operating system.
Special commands to add and replace field devices and to replace the control unit are
included. With the modes already explained, go to “CONFIGURATION MENU”
from “MAIN
MENU”.
10.1 New control unit
This operation is required when it is necessary to replace the control unit with a new one.
This command can be used to maintain system configuration and transfer it automatically to
the new control unit, keeping the replacement operations to a minimum and, above all,
avoiding system re-configuration. Carry out replacement as follows:
1. disconnect the system from the power supply
2. disconnect the control unit
3. replace it with the new control unit
4. power up the whole system again
5. carry out the following operations:
From “CONFIGURATION MENU” on the control unit use the key to go to “NEW
CENTRAL UNIT”, then press
……
, to enter the menu in Fig. 10.1.
The control unit automatically recognizes the field devices, recreating the same
configuration as the previous control unit inside itself. The operation may take a few
minutes; during that time the status LED of the field devices will be flashing rapidly.
