Using Instruction

Optional step (connecting flow sensor)

The serial number and QR code can be removed from the NovoCon® M label and added to the installation drawing.

Dip switches for addressing and bus protocol selection are located under the lid of the actuator.
Dip switches 1 to 7 are used to assign the MAC address manually. The default MAC address assignment method is Auto MAC addressing for BACnet MS/TP and DIP Switches for Modbus RTU.
Dip switch 8 is used to select between BACnet MS/TP (OFF=Default) and Modbus RTU (ON).
When the protocol is changed on DIP Switch 8, a power cycle is required.
For termination of the last unit on the field bus, turn the DIP Switch R located between the connectors to ON.

Safety Instruction

Safety Note

To avoid injury and damage to persons and devices, these instructions must be carefully read and observed before assembly and commissioning.
Necessary assembly, start-up, and maintenance work must be performed only by qualified, trained, and authorized personnel.
Switch off the power line before wiring the actuator.
If the NovoCon® M network is supplied with two or more AC power boosters, caution must be observed when disconnecting one of the transformers from the high-voltage power line. As the NovoCons are connected in a daisy chain, there may be high voltage on the primary side of the disconnected power supply. Disconnect always on both the primary and secondary side of the transformer.

Firmware update

We recommend validating the firmware version before installation.
The latest firmware can be downloaded at www.novocon.com by selecting the tab: Support files.
