Initial Commissioning

The initial commissioning of the CMS-660 control unit has to be carried out manually.
In order to guarantee a correct commissioning of the device, please follow the procedure here
described:
1. Connect the CMS-660 control unit to the external power supply: the device switches on and the
initial commissioning phase automatically begins.
2. The LED "Status" on the front of the device starts to blink in yellow, indicating no sensor is assigned
to the control unit. At the same time, the LED of each sensor is flashing slowly.
3. Assign sensors to the control unit by pressing the sensor's pushbutton. The sensor's LED now lights
up continuously, indicating that it is assigned.
The sensor's ID logic follows the sensor's assignment order: the first sensor assigned to the control
unit will have ID 1, and so on.
Once added the new sensors, please follow one of the three ways to leave the configuration mode:
• Configured timeout
• Push the reset button for < 1 sec
• Press the pushbutton of any CMS sensor already added for three times
After leaving the configuration mode the LED "Status" of the control unit is green, indicating normal
operation. If it is necessary to enter the configuration mode again after the first commissioning of the
device (e.g. one more sensor has to be assigned to the control unit), please refer to the following
instructions:
• If no sensor is assigned: press the "Reset" button for ~1 sec (1 beep) and then assign the sensors as
described above.
• If new sensors must be added to the control without changing the Modbus ID of the control unit:
press the "Reset" button from 3 to 6 sec (2 beeps) and then reassign all the sensors, including the new
ones, to the control unit as described above.
• If new sensors must be added to the control unit and all the configuration settings, including Modbus
ID of the control unit, have to be reset: press the "Reset" button from 6 to 9 sec (3 beeps). This way
the device is reset to factory conditions.
• In addition the Modbus function "Add Sensor" can be used. (page 23)
