Manual control and emergency operation
The manual control and emergency operation required in building automation can
be implemented with a PCD3.C200
1)
module carrier and the PCD3.A810 (digital)
and PCD3.W800 (analog) manual control modules. These manual control modules
are based on digital and analog output modules, which can be activated either via
the user program or via the manual switch.
●
For emergency operation, the manual control modules must be operated in
a PCD3.C200 module carrier with external power supply. The external power
supply is required in order to continue operating the manual control modules in
emergency operation in the event of a cable break or during maintenance work
on the CPU.
●
In this module carrier PCD3.C200 (from HW version C) and possibly other
module carriers, manual control modules may be operated mixed with other
data point modules!
● When configuring a PCD3 system, attention must be paid to the power
requirements of the data point modules in the PCD3.C200 and the following
module carriers.
It is recommended to use the PG5 Device Configurator for this purpose.
