CORRIGO VENTILATION 3.6 MANU

Chapter 16 Expansion units
2 and 3 port Corrigo units are available with or without display. Both models have a TCP/IP port and
one or two serial ports. For a list of the various models, see the Corrigo model overview in chapter 2.

and, possibly, a SCADA system. In an E…3W-3 model,
port 3 is the TCP/IP output.
The serial ports (ports 1 and 2) are used for expansion purposes, e.g for connection of expansion units,
external display and Vacon NXL / Lenze SMV / Omron V1000 / Emerson / LS / EBM / Danfoss FC
101 / EC Blue frequency converters and Presigo pressure transmitters. A maximum of two frequency
converters and two expansion units can be connected. The units must be Corrigo controllers. There is
no point in using slave controllers with a display, since the display cannot be used or show anything.
However, an E3-DSP is required when initially starting up slave units without display. All
configuration takes place using E tool

, or via the display on the master controller. All inputs and
outputs can be viewed in the master controller. For configuration, see chapter 17.
As of version 3.1, frequency converters and expansion units can be used together.
Ports 1 and 2 have the same functions. They can, however, not be configured to have the same function
at the same time. The TCP/IP port (port 3) can be used to connect the controller to CLOUDigo or,
optionally, to use the web server contained in the unit. This may need to be reloaded after the Corrigo
has been configured. For more information, see the E tool

16.2 Wiring
16.2.1 Vacon / Lenze / Omron / Emerson / LS / EBM / EC
Blue frequency converters / Eltwin A/S EC controller for
heat exchangers
If the Corrigo is to control either one or two Vacon NXL / Lenze SMV / Omron V1000 / Emerson /
LS / EBM / Danfoss FC 101 / EC Blue frequency converters / Eltwin A/S EC controller, this will take
place via Modbus communication using port 1 or 2.
It is possible to run two parallel connected frequency converters for supply air and two parallel
connected frequency converters for extract air. The supply air fan will have address 1 and the parallel
supply air fan address 3. The extract air fan will have address 2 and the parallel extract air fan address
4. Eltwin A/S EC controllers will have address 7.
For additional settings for frequency converters, see appendix at the end of this document.
