8. Starting the CleanMaster hood
When the device is first started, the control logic must be provided with the basic hood informa-
tion to ensure its correct operation.
Hood connections in a Master/Slave assembly.
If the main controller is used with several hoods, a ModBus compli-
ant data cable must be connected between these hoods, such as
Datajamak 2x(2+1)x0.24. The ModBus data cable is connected to the
control device’s ModBus channel 2, to the points:
3: protection
4: ModBus (-) / B2
5: Modbus (+) / A2
1. Choose your language
Finnish, Swedish or English
2. Master/Slave
Climecon CleanMaster can be the device’s Master or
Slave device.
The choice between Master or Slave is made when the
device is started for the first time.
If the device in question is a separate hood or a group of
hoods where all hoods act independently, choose Mas-
ter. Other settings do not need to be changed.
If the device in question is a group of hoods where sev-
eral hoods are controlled with one control device, select
Master from the main controller and then the Slave
devices to be used with the addresses 1–9.
In addition to this, all Slave devices must be defined as
Slave devices during the initial start, and must be deter-
mined a Slave address from 1 to 9.
The connection must be made in accordance with the ModBus architecture.
The main controller has to be the 1st bus device, from where it’s cabled to
the Slave hood 1–9. After the last device in the chain, the bus is terminated
with a terminating resistor (100 ohm). Read more on page 21.
