Application
24V supply from control unit
Complies with EN54
24V supply from control unit
without emergency operation / emer-
gency power supply
autonomous power supply
Complies with EN54
autonomous power supply
without emergency operation / emer-
gency power supply
Note:
Emergency operation circuit also required between other CPUs or to a separate Gateway
–
– Emergency operation circuit and the emergency power supply are not laid out as a loop line
Route emergency power supply in a separate cable or in the C-Bus cable feedback

At least one control console per system must comply with standard EN54, i.e.
must have Emergency operation capability and Emergency power supply.
Emergency power supply
This consists of a second supply circuit to stations located elsewhere
For this purpose the AlgoPilot control console has 2 de-coupled supply inputs

Two requirements must be met for control consoles located elsewhere. At least
one control console must comply with standard EN54 (i.e. have emergency opera-
tion capability and emergency supply).
EN54 requirements:
Communication as loop line
–
Operation also in emergency mode
–
second de-coupled 24 V supply
–
The number of wires in the connection cable depends on the application:
a) Are control consoles supplied from the control unit or autonomously with 24V?
b) Is an emergency power supply also provided according to EN54?
c) Is the emergency operation circuit also provided?
