3 Commissioning
3.1 Before you start
3.1.1 Commissioning process
The main steps in the commissioning process are the following:
▪Configuring the basic controller settings (including: selecting the installation case)
▪Setting the Modbus communication parameters (optional)
3.1.2 Commissioning information
Before the system start-up, the controller settings (including the correct installation case) and optionally the Modbus
communication parameters have to be set.
Factory settings
The airflow range for Halton Max Ultra Circular (MUC) is preset at the factory. The factory settings for the control
signal and feedback signal are the same, but they can be configured individually. If the airflow range is not
specified by the customer, the default factory settings are the following:
▪Minimum airflow rate: 0 l/s
▪Maximum airflow rate corresponds to an airflow velocity of 10 m/s
The maximum airflow rates in the following table are given with an airflow velocity of 10 m/s. This applies to all
Halton Max Ultra Circular (MUC) actuator models.

3.1.5 Modbus RTU communication
The Halton Max Ultra Circular (MUC) airflow control damper can communicate with the Building Management
System (BMS) via Modbus RTU. With the Modbus register, you can read and configure parameter values.
The default communication settings are Slave-ID 1, 115200bsp, O (Odd), 8 (bit), 1 (stop bit).
You can change the communication settings on the correct parameter pages of the Halton Max Ultra Circular
(MUC) controller:
▪Controller support slave ID: 1..247
▪Communication speed: 4k8 / 9k6 / 14k4 / 19k2 / 38k4 / 56k0 / 57k6 / 115k2
▪Parity: None / Even / Odd
There can be up to 64 devices in one Modbus RTU bus. The length and quality of the bus cable as well as other
disturbances can affect the maximum number of devices. The shortest poll time of the controller is 200 ms.
To configure parameters using Modbus, you need to send a password to MUC before it approves the changes.
When configuring the Holding register or Coils, first send the register value you want to change. After that, send
value 9055 to Holding register 40905, then send value 0 to Holding register 40905.
3.1.6 Self-diagnosis function
Halton Max Ultra Circular (MUC) includes an advanced self-diagnosis function for monitoring the controller's own
performance.
If the controller is installed in a location where the airflow is highly turbulent and the air velocity is high
(approximately 10 m/s), it can cause a wrong kind of measurement action to the sensor. In cases like this, the self-
diagnosis function restarts the measurement sensors. During the restart process, the damper blade goes into the
close position for 1 second, then continues normal operation.
If the airflow continues to be highly turbulent, the controller goes into 'Service request' mode after three sensor
restarts. In 'Service request' mode, text Fault 7 is showing on the controller display and the damper blade goes into
the 30% open position. You can reboot the 'Service request' mode in the following ways:
▪In the controller parameter menu
▪By rebooting the controller
▪With a Modbus parameter
▪By using the scheduled restart function
For instructions, see Rebooting the controller and Configuring the scheduled restart function.
