5.1 CPU cards
If a CPU card for a CC1142 (E3X10x), CI1142 (B3Qxxx), CI1145 (E3X120) control unit or
a CT1142 (B3Qxxx) terminal is replaced, the following operations must be carried out:
Disconnect control unit/terminal from power supply
Replace the CPU card, reconnect all cables
Re-adjust all switches and jumpers
Reconnect power
Repeat download of configuration data
5.2 I-Bus cards
If an I-Bus card (E3Mxxx, E3Lxxx, E3Gxxx, ...) is replaced, the following operations must
be carried out:
Disconnect control unit from power supply
Replace the I-Bus card, reconnect all cables
set the correct I-Bus address !
Reconnect power
Configuration data does not need to be downloaded again
5.3 E-Bus cards
If an E-Bus card (K3M071, K3M111, K3M080, ...) is replaced, the following operations
must be carried out:
Disconnect control unit from power supply
Replace E-Bus card, reconnect all cables
Note the mounting space
Reconnect power
Configuration data does not need to be downloaded again
5.4 Interactive devices
Automatic detectors can be replaced without localization having to be repeated pro-
viding the type is not changed The following operations must be carried out:
Remove the old detector from the base
Insert new detector (line does not have to be disconnected from power supply)
As long as the new detector type is the same as the old detector type, the system
reconfigures itself automatically
If a different detector type is purposely installed, a change in the configuration is nec-
essary:
Change the device type accordingly in the physical structure
Download the updated configuration data to the control unit
If the ID module of a base or the whole base is replaced, the configuration must be
modified as follows:
In the physical structure, set the D-Bus address of the replaced device to 0 (using
raw data editor)
Repeat localization and assignment procedure for the device concerned
