PRODUCT DESCRIPTION

The FCVC8-R series are intelligent sensors featuring adjustable temperature, relative humidity and TVOC / CO2eq ranges. Based on this TVOC measurement, an equivalent CO2 level (CO2eq) is calculated. The TVOC concentration is an accurate indicator for indoor air quality. Based on the temperature and relative humidity measurements, the dew point is calculated. The used algorithm controls a single analogue / modulating output based on the measured T, rH and TVOC values, which can be used to directly control an EC fan or an actuator powered damper. All parameters are accessible via Modbus RTU.

MOUNTING INSTRUCTIONS IN STEPS

Before you start mounting the unit, read carefully “Safety and Precautions”. Proceed with the following steps:

ATTENTION When planning the installation, allow enough clearance for maintenance and service. Mount the sensor in a well-ventilated area.

Inset mounting

1. Disconnect the supply voltage.2. Remove the cover of the enclosure and take the controller out of the housing, so

that it can be easily connected. 3. Do the wiring according to the wiring diagram (see Fig. 1).

7. Put the internal enclosure into the external one and fix it using the delivered screws and washers. (Fig. 4).

8. Put back the frame cover of the enclosure.9. Switch on the power supply.10. Customise the factory settings to the desired ones via the 3SModbus software

or the Sensistant configurator. For the default factory settings, see Modbus register maps below.

Optional settingsTo assure correct communication, the NBT needs to be activated in only two devices on the Modbus RTU network. If necessary, enable the NBT resistor via 3SModbus or Sensistant (Holding register 9).

NOTE On a Modbus RTU network, two bus terminators (NBTs) need to be activated.

NOTE Mount the unit so that the terminal block and connections are at the lower side.




ATTENTION Do not expose to direct sunlight!

NOTEThe sensor is not designed, manufactured or intended for control or monitoring equipment in environments requiring life safety performance, in which the failure of the sensor could lead directly to death, personal injury, or severe physical or environmental damage.

OPERATING INSTRUCTIONS

The unit is supplied with electrical energy at voltages high enough to inflict personal injury or threat to health.

ATTENTION

NOTEThe compounds released from plastics may influence the sensor readings. Please allow several days for the sensor to stabilize before you obtain the accurate values.

Calibration procedure:Sensor calibration is not necessary. All sensor elements are calibrated and tested in our factory.In the unlikely event of TVOC / CO2eq sensor element failure, this component can be replaced.

BootloaderThanks to the bootloader functionality, the unit firmware can be updated via Modbus RTU communication. With 3SM boot Application (part of 3SM center software suite), ‘boot mode’ is automatically activated and the firmware can be updated.

NOTE Make sure the power supply does not get interrupted during “bootload” procedure, otherwise you risk losing unsaved data.

LED indications

1. When the green LED is on, the measured value (temperature, relative humidity or TVOC / CO2eq) is between the minimum and maximum alert range values (Fig. 6 - 1).

2. When the yellow LED is on, the measured value (temperature, relative humidity or TVOC / CO2eq) is in the alert range (Fig. 6 - 2).

3. When the red LED is on, the measured value (temperature, relative humidity or TVOC / CO2eq) is below the minimum measurement range value or above the maximum value. Blinking red LED indicates loss of communication with a sensor (Fig. 6 - 3).

NOTE By default, the LED indication refers to temperature measurements. This can be changed to relative humidity or TVOC / CO2eq values via Modbus Holding Register 79 (see Table Holding registers below).




Ambient light sensor

The measured light intensity in lux is available in Input Register 41. Additionally, an active and standby level can be defined in Holding registers 35 and 36. Input Register 42 indicates if the measured value is below standby level, above active level or in between both levels:

■ Ambient light level < standby level: Input Register 42 indicates “Standby”. ■ Ambient light level > active level: Input Register 42 indicates “Active”. ■ Standby level < Ambient light level < Active level: Input Register 42 indicates “Low intensity”.

VERIFICATION OF INSTALLATION INSTRUCTIONS

After switching on the power supply one of the LEDs lights up according to the status of the measured variable. If this is not the case, check the connections.
