Corrigo ventilation 3.4 manu

102 Chapter 17 Configuration Manual Corrigo Ventilation, revision R
Expansion unit
In order to connect additional I/Os (in- and outputs) to the Corrigo, port 1 or 2 should be set as an
expansion unit (only Corrigo controllers can be connected). It is possible to connect two expansion
units, giving a maximum number of 28*3 = 84 inputs/outputs. The expansion units must have the
addresses 241:1 and 241:2 respectively (ELA:PLA).
Expansion unit1
None
Expansion unit2
None
To initiate the expanded controllers, select ”Expansion unit” at start-up (see below). If the controller
does not contain program version 3.0 or later, the initiation must be made via E tool
©
(see the E
tool
©
manual). However, this requires that the controller hardware is of a second generation Corrigo
(…S). After initiating the expansion units and setting the master controller, all inputs and outputs
are available for configuration in the master controller under "Configuration" / "Inputs/Outputs" (the
expansion units’ in-/outputs are named Exp1/Exp2).

Frequency converters
Up to two separate Vacon NXL / Lenze SMV / Omron V1000 / Emerson Commander / LS iG5a /
LS iS7 / EBM-PABST / Danfoss FC 101/ ABB ACS/ ECBlue frequency converters can be
controlled via modbus communication. Corrigo can manage two supply air fans in parallel and two
extract air fans in parallel. Miscellaneous alarms and indications can be read from the frequency
converters. For a complete list of alarms, see the alarm list. For communication addresses, see the
“Appendix 1” at the end of this manual
The Corrigo Modbus settings are listed below. They are not adjustable and must also be set in the
current frequency converters.
Modbus address: Supply air fan = 1, Extract air fan = 2, Parallel supply air fan = 3, Parallel extract
air fan = 4
Speed: 9600 bps, 1 stop bit, no parity
For additional settings for every model, see Appendix 1 at the end of this document.

Expansion unit and frequency converters
Frequency converters can be used in combination with expansion units on the same port. The master
controller will switch the port between Modbus and EXOline in order to communicate with the
frequency converters via Modbus and with the expansion unit via EXOline.
