13-4-7.Communication error with the digital input / output relay
interface is displayed.
The address switch setting of the digital input / output relay interface does not match that in the setting file.
13-4-8.Communication error with the energy monitoring relay
interface is displayed.
13-4-9.Page breaks in alarm email were deleted, everything
appears in one line.
No. Cause Solution
1 The digital input / output relay interface is not turned on. Check if the “POWER” LED of the digital input / output relay interface
illuminates.
2 The RS-485 communication wiring is not connected or
disconnected.
Check the conduction of the communication wiring.
3 The RS-485 communication wiring is incorrect or
connected with wrong polarity.
Check the terminal block connected.
4 The terminal resistance is not connected. Check the value of the terminal resistance with a tester.
5 The wiring length is too long. Change it to the specified wiring length.
6 The communication circuit of the digital input / output
relay interface failed.
Replace with the normal digital input / output relay interface and check that
the communication is available.
7 The communication circuit of the controller failed. Replace with the normal controller and check that the communication is
available.
8 Noise is superposed on the communication wiring. Check the waveform between RS-485 communication wiring A and B.
If noise is superposed, identify the noise source and remove it.
9 The communication cable in use is not the specified
one. (Wire diameter is smaller)
Change it to the specified communication cable.
No. Cause Solution
3 The RS-485 wiring is defective between the digital input
/ output relay interface and the controller.
1.Check the address switch setting of the digital input / output relay
interface and the setting in the setting file.
2.Check if the RS-485 LED (Green) of the digital input / output relay
interface blinks.
No. Cause Solution
1 The energy monitoring relay interface is not turned on. Check if the “POWER” LED of the energy monitoring relay interface
illuminates.
2 The address switch setting of the energy monitoring
relay interface does not match that in the setting file.
1.Check the address switch setting of the energy monitoring relay
interface and the setting in the setting file.
2.Check if the RS-485 LED (Green) of the energy monitoring relay
interface blinks.
No. Cause Solution
1 Specifications for Outlook (deleting excess page
breaks).
1.While the email is open in Outlook, select the [Format] menu, and
deselect the [Unwrap Text] check box.
2.Use an email software other than Outlook.
