Note:

when active/reactive energy is shown on the display. When the expanded display is operated during active energy screen, reactive energy’s lower digit is not expanded. For displaying lower digits reactive energy, please operate by displaying reactive energy screen.

Monitoring of Upper/Lower Limit

● Monitoring of Upper/Lower Limit (Max. 4 points)

There is an output of upper/lower limit alarm when plug-in optional module ME-4201-NS96 is mounted. (Since contact output is 1 point, it becomes OR output set in upper/lower limit alarm item)

■ Upper/Lower Limit Alarm Display by LCD

Alarm occurrence status can be checked by current status display and maximum/minimum value display.

Alarm display on current status screen

Alarm display on maximum /minimum value screen

● Setting of Alarm Output Delay

Time of alarm output after the maximum value and minimum value is reached can be set. With this function, alarm output caused by frequency change at start-up current of a motor and start-up of private power generating facility can be avoided. Furthermore, maximum value and minimum value do not update during alarm delay.

2. Analog output signal cables should keep the distance from the other power cables and input signal (VT, CT and auxiliary power) cables, and should not be bunched. And use the shielded cables or twisted pair cables so that it is not affected noise, serge, and induction. Also, the wiring cables should be as short as possible.

3. In case of ME96NSR-MB with ME-4201-NS96, the ModBus interface and the analog outputs do not have the insulation between them.

Note

1. As for CC-Link cable, use the designated cable. Each of Ver.1.10 compatible CC-Link cables, CC-Link specified cables, and CC-Link specified high-performance cables cannot be used together with other cable types. If used together, correct data transmission will not be guaranteed. The terminating resistor is different depending on the applied cable.

2. Connect the shielded wire of the CC-Link specified cable to “SLD” of each module, and earth the both ends of the shielded wire “FG”. The SLD and FG are connected into the module.

3. Keep the distance between CC-Link cables to power lines (At least 10cm). When connecting long distance in parallel, please set apart more than 30cm.

4. Fill the requirements of total wire distance, station distance, and terminal resistance value according to baud rate and type of cable. (As for detail of the requirements, refer to the operation manual for CC-Link master unit.)

5. To the units of both the end of CC-Link line, the terminal resistors should be attached. And the terminal resistors should be attached in between DA and DB.
