E2418DP
Rev 27.05.2021
The screwless quick connect spring terminals on the E2407 are suitable for a wide range
of wires with cross-section 0,2...1,5 mm
2
. The recommended wire stripping length is 8...9
mm. Push the spring loaded terminal lever, insert the wire end into the terminal hole and
release the lever.
Use twisted pair cable, e.g. LiYY TP 2×2×0,5 mm2 or CAT 5, to connect the device to the
RS485 network. Use one pair for A and B wires and the second pair for common 0V and
power +U wires. to connect the transmitter to the Fieldbus network.polarity must be
respected when connecting to an external RS485 network.
Overall length of all connections via the RS485 interface should not exceed 1200 m.
Both analog outputs can be independently changed between 4-20 mA and 0-10 V type
using jumpers J1 (OUT1) and J2 (OUT2). By closing pins on a specific jumper the related
output is 0-10 V, with an open jumper the output is 4-20 mA. Power restart is required after
changing the position of the jumpers.
NOTE! Power restart is required after changing the position of the jumpers.
4. Turn on the power. The operating status is indicated by the LED on the PCB of the
device. The LED response to different processes is presented in the following table:
Mode
LED mode
During calibration mode or sensor heating
period (if activated)
0.5 Hz (50% on, 50% off)
During the Modbus communication cycle
Short on-off pulses
Normal operating/measurement
Continuously on or off
5. Make sure that the transmitter is properly mounted, the external devices connected,
power on and control LED is constantly lit. Place the lid back and fix it with the screws. To
connect the device with measurement point use tubes of appropriate diameter (4 or 6 mm)
and length.
NOTE! The connecting tubes should not be squeezed or folded.
