“FCR3 three-phase controller” +030222150 - rel. 1.3 - 12.01.2021
Alarm management
When an external protector / control signal is triggered, the output can
be forced to a set value.
A LED is shown on the display and a relay digital output is provided to
control external devices, with NC-COM-NO confi guration.
Serial connection
An RS485 serial output is available for connection via two wires plus
shield to the supervisor or telemaintenance network that support the
Modbus® protocol. The serial connection has been duplicated with two
terminals to simplify network connections. In fact, several FCR devices can
be connected to the network, setting the address on each device using
a dipswitch or parameter in the memory. When serial communication is
active, the link LED comes on (blue).
Ingress protection
The gasket inside and the materials used to make the case guarantee the
controller IP54 ingress protection
Fastening
The device is fastened using 4 screws.
CE mark/Electromagnetic compatibility
The FCR controller is compliant with the EU standards on electromagnetic
compatibility, while quality and safety are ensured by the CAREL ISO
9001 certifi ed design and production system and by the CE mark on the
product.

INTERFACE
The status of the controller is displayed using LEDs that are only visible
with the cover open. The LEDs indicate:
•
power on (green LED);
•
serial connection status (blue LED);
•
alarm status (red LED).
To set the operation of the controller, 3 trimmers and 2 dipswitches are
available for the main functions, while internal parameters are used to set
all the other functions. The parameters can be set using the programming
key, while access to the parameters for display and setting, as well
as access to the variables that represent the status of the controller, is
available via serial line.
