4.1.1 Indication elements
The devices each have a green Power LED (Pwr). A red Error LED and two yellow Status LEDs are
also provided.
4.2 Properties and features
nSensors for monitoring humidity, temperature and distance
nManual teach-in process via gesture control
nDevice variants with screw or spring-loaded terminal connection
nFreely configurable switching outputs (NC/NO contacts)
4.3 Operating principle
The cabinet guards of the IMX12-CCM… series monitor temperature and humidity within the
set limit parameters and door status (open/closed) in control cabinets. The ambient humidity/
temperature sensor and a triangulation sensor are used to detect the ambient conditions.
Values above or below the limits are indicated by the LED and the corresponding switching
output. The switching contacts indicate limit value overshoots and undershoots to the higher
field level.
The device processes the data via an 8-bit microprocessor with a 256-byte internal EEPROM.

V01.1 | 2021/08 9
4.4 Functions and operating modes
Two galvanically isolated potential-free switching outputs, each with a 100mA load capacity at
30V, are provided for outputting limit value overshoots. The assigning of limit value overshoots
to switching outputs and the output type (NC/NO contact) can be set via the HART communica-
tion interface.
4.4.1 Internal EEPROM
The internal EEPROM has a total capacity of 256Kbytes and consists of 4 memory modules with
a memory capacity of 64Kbytes each. 12 bytes for each data set are required to store the
internal sensor values. If only internal sensor values are stored, the following recording intervals
are possible:
Time_interrupt_storage For 12 data bytes
5 min 76 days
30 min 455 days
60 min 910 days
The following data is stored in the internal EEPROM:
nArticle number
nFirmware version
nProduction order
nManufacturing date
nSerial number of the device
nLimit values for humidity, temperature, door gap and brightness
nComparison values for humidity, temperature, door gap and brightness
nHysteresis for humidity, temperature, door gap
nAdditions (in %) for the automatic generation of limit values from the calibration values
nTime interval for storing data in the external EEPROM
nThe time interval between two consecutive measurements
nMax. tuning time until the settled state
nNumber of errors until the error message for humidity, temperature and door gap is
triggered
nConfiguration bytes and error byte

7 Commissioning
The device is operational automatically once the cables are connected and the power supply is
switched on.
NOTE
Turck recommends that the short circuit monitoring is deactivated when the device
is supplied by a DCS/PLC card.

Operation
14 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
8 Operation
In normal operation, the device performs the following processes automatically:
nReading configuration data
nRecording current measured values (temperature, humidity, brightness, door gap)
nMonitoring measured values for limit value overshoots and undershoots
nStoring of measured values in the external EEPROM
nCyclical sampling after teach-in processes
If an error occurs during normal operation at one of the integrated sensors, the red LED is lit
and the current consumption increases to >20mA. The device continues to run in normal
operation.
8.1 LED indications
The devices each have a green Power LED (Pwr). A red Error LED and 2 Status LEDs are also
provided.
The LEDs have the following indication functions:
LED Color Meaning
Pwr Green Device is operational
Green flashing (0.5Hz) Manual teach-in running
Err Red Error at one or multiple sensors
Short red Manual input error
Red flashing (0.5 Hz) Error during teach-in
Ch1 Yellow Limit value at switching output 1 overshot or
undershot
Off Parameters within the limit values
Ch2 Yellow Limit value at switching output 2 overshot or
undershot
Off Parameters within the limit values
The HART interface outputs limit value overshoots and undershoots as follows:
Parameter Memory Bit
General limit value overshoot Internal/external Bit0
Humidity limit value Internal/external Bit1
Temperature limit value Internal/external Bit2
Door gap limit value Internal/external Bit3
Error during teach-in Bit4
Output NC contact/NO contact Bit5

V01.1 | 2021/08 15
9 Setting
9.1 Setting limit values (via the teach-in function)
The device can be adapted to the particular installation requirements via a manual teach-in
operation.
The following default limit values are set in the device:
Parameter Lower limit value Upper limit value
Humidity 0% 80%
Temperature -25 °C +60 °C
Door gap 4 cm 20 cm
The teach-in operation is controlled by the brightness sensor. If faults occur during the teach-in
operation, the red LED is lit for 1 s and the green LED switches from flashing to constant. The
teach-in operation is aborted and the device switches to Normal mode.

Setting
16 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
Cover the door sensor (t1…t2).
Cover the brightness sensor for 2…10s (t2…t3).
aThe Pwr LED flashes green.
Uncover the brightness sensor again for max. 10s (t3…t4).
Cover the brightness sensor for max. 10s (t4…t5).
Uncover the brightness sensor again for max. 10s (t5…t6).
Uncover the door sensor (t6).
Close the control cabinet door (t6…t7).

The parameters for temperature, humidity and brightness in the control cabinet must be within
the set values during the tuning phase. The values are defined in the device as follows:
Parameter Value
Humidity Max. humidity change: 1 %
Temperature Max. temperature difference: 2 %
Door gap Max. change: 0.2 cm
The teach-in operation is automatically aborted and must be repeated if the values listed in the
table are not reached during the tuning phase. An error confirmation is not necessary.

V01.1 | 2021/08 17
If faults occur during the teach-in operation, the red LED is lit for 1 s and the green LED switches
from flashing to constant. The teach-in operation is aborted and the device switches to Normal
mode.
NOTE
The set limit values are written to the internal EEPROM if they are within the values
specified in the data sheet. If the set limit values are outside the specifications in the
data sheet, the values specified in the data sheet are stored in the EEPROM.
