MOUNTING & OPERATING INSTRUCTIONS IN STEPS
Before you start mounting the RMFPX-2R, read carefully “Safety and Precautions”.
Choose a smooth surface for installation (a wall, panel and etc.).
Follow these steps:
1. Using a flat screwdriver, remove the front white cover by releasing the snap-fits
on its both sides (see Fig. 1 Snap-fits release).
2. Insert the cables through the opening on the rear plate (See Fig. 2 Mounting
dimensions.)
3. Using suitable fastening materials (not supplied), position the room sensor at
least 1,5 m from the floor. When planning the installation, allow enough clearance
for maintenance and service. Mount the sensor in a well-ventilated area. Mind
the correct mounting position and unit dimensions. See Fig. 2 and Fig. 3.

Optional settings
If your unit is the first or the last unit on the Modbus RTU network (see Example 1
and Example2), enable the NBT resistor via 3SModbus or Sensistant. If your device
is not an end device, leave the NBT disabled (default Modbus setting).

ATTENTION
If an AC power supply is used with any of the units on a Modbus network, the
GND terminal should NOT BE CONNECTED to other units on the network or
via the CNVT-USB-RS485 converter. is may cause permanent damage to the
communication semiconductors and/or the computer!
ATTENTION
Do not exceed the maximum power supply rating! Measure before installation!
Unregulated 24 VAC supply units provide higher nominal output voltage and
activate the integrated fuse protection.
ATTENTION
We advise you not to use G and F-type articles together on the same network. If
G and F-type articles are used together on the same network, make sure you use
separate power supplies for both types. Always connect different article types to
separate AC transformers or use the same article version.
CAUTION

OPERATING INSTRUCTIONS
Calibration procedure:
No relative humidity and temperature sensor calibration is necessary.
By default, the CO2 sensor element is self-calibrating.
Optionally, the CO2 sensor element can be calibrated and verified manually via
SSCDM. For this purpose, the CO2 sensor element is removable.
More information is available in the SSCDM datasheet and mounting and operating
instructions.
Bootloader
anks to the bootloader functionality, the sensor firmware can be updated via
Modbus RTU communication. To enter ‘Boot mode”, put a jumper onto pins 3 and
4 of the P1 header and restart the power supply (see Fig. 5). Once ‘Boot mode’ is
activated, the firmware can be updated via SM Boot application (part of 3SModbus
software suite) or Sensistant.
Fig. 5 P1 header
123 45
123 45
Put a jumper onto pins 1 and 2 and wait
for at least 5 seconds to reset the Modbus
communication parameters
Put a jumper onto pins 3 and 4 and restart
the supply to enter bootloader mode
NOTE
LED indications
1. When the green LED is on, the measured value (temperature, relative humidity or
CO2) 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 CO2) is in the alert range (Fig. 6 - 2).
3. When the red LED is on, the measured value (temperature, relative humidity or
CO2) 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).
Fig. 6 LED indications

By default, the LED indication refers to temperature measurements. is can be
changed to relative humidity or CO2 values via Modbus Holding Register 26 (see
Tabl e Holding registers below).
Ambient light sensor
e measured light intensity in luxes is available in Input Register 5. Additionally,
an active and standby level can be defined in Holding registers 34 and 35. Input

Register 6 indicates if the measured value is below standby level, above active level
or in between both levels:
■
If the measured light level is below the Standby level, Input Register 6 indicates
“Standby”.
■
If the measured ambient light level is above the Active level, Input Register 6
indicates “Active”.
■
If the measured ambient light level is between the active and stand-by level, Input
Register 6 indicates “Low intensity”. When this feature is used, it is advisable to
adjust the active and standby levels in Holding Registers 34 and 35 according to
the actual ambient light conditions around the sensor.
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.
