Manual CORRIGO U-SERIE 2002-09
Analogue outputs AO
CORRIGO has analogue outputs AO for controlling actuators
Output signal 0...10 V DC, 5 mA. Short-circuit protected.
These outputs should refer to terminal 41, signal neutral.
Signal neutral, terminal 41, in the CORRIGO is internally connected to sytem neutral
G0 on terminal 43.
It is therefore important that any actuators sharing the CORRIGO supply transformer
are wired with their supply neutral connected to the same transformer pole as the
CORRIGO terminal 43.
AO1 Control valve HS1-CV1
AO1 is only active if HS1-CV1 has been configured as a 0...10 V actuator. See
under Configuration.
AO2 Control valve HW-CV1 or THW-CV1
AO3 Control valve THW-CV1 or THW-CV2
AO4 Control valve HS2-CV1 (C20 only)
AO4 is only active if HS2-CV1 has been configured as a 0...10 V actuator. See
under Configuration.
AO5 Control valve HS1-CV2 (C20 only)
AO5 is only active if HS1 has been configured for two actuators in sequence.
See Configuration.
AO6 Control valve HS2-CV2 (C20 only)
AO5 is only active if HS2 has been configured for two actuators in sequence.
See Configuration.
Digital inputs DI
CORRIGO has digital inputs DI for activation of certain functions and input of external
alarm signals.
These inputs may only be wired to voltage-free contacts.
These inputs may only refer to the common DI pole on terminal 22.
Terminal 22 does not have the same potential as other signal neutrals in the CORRIGO
and may not be connected to any other terminals except the DI inputs.
The inputs are configured such that a closed contact will activate the function/alarm
DI1 Indication circulation pump HS1
DI2 Indication circulation pump HWC
DI3 Expansion vessel pressure alarm
DI4 External alarm
DI5 Not used
DI6 Indication circulation pump HS2 (C20 only)
DI7 Not used
