3Electrical Connection
The MFE600H energy electromagnetic flowmeter converter can be divided into integrated converter and
separated converter, and the wiring diagram is shown in Figure 1 and Figure 2.
When wiring, please note:
a) RS485 communication cable needs to use two-core twisted pair shielded wire;
b) The same cable shall not be used for the power line and 4mA~20mA DC signal line. Two cables
shall be connected separately.
3.1 Integrated wiring
Figure 1 Integrated wiring diagram
When connecting the power cable, pay attention to select the appropriate voltage level wiring. For
different voltage levels, select 220V AC or 24V DC wiring to avoid power wiring faults.
When wiring, select the corresponding power terminal to connect to the power line according to the
product specifications, and then connect to the signal line according to the required output signal. See
Table 2 for the specific meaning of the integrated electromagnetic flowmeter wiring terminals.

4Start up
4.1 Switch on
Before turning on the power, please check that the system has been properly installed as required,
including:
a) The instrument shall be mechanically safe and shall be installed in accordance with regulations;
b) The power supply shall be connected according to regulations;
c) The electrical connection wire of the cavity shall be protected, and the cap shall be tightened;
d) Please check whether the running data of the power supply is correct.
4.2 Converter start-up
The measuring instrument is composed of a sensor and a converter and is ready for immediate use
when it is supplied. All operating data is factory set according to your order, please refer to the provided
inspection report for details.
After turning on the power, the flowmeter performs a self-check first. After the self-check, the flow meter
directly starts flow measurement and displays the current measured value.

5Operation
5.1 Key instruction
The electromagnetic flowmeter display and operation interface are shown in Figure 4. There is a key on
the left side of the screen and 4 keys on the bottom side of the display screen.
Figure 4 Operation interface
The meaning of the keys and operation methods are shown in Table 6. The composite key needs to
press two keys at the same time. If there is no key operation within 10 minutes, it will automatically
return to the main screen. This version does not provide touch keys or infrared remote-control keys. If
you need to set up, you must open the front cover.
