Troubleshooting
Note
Power is not being supplied.
Power supply fuse has blown.
Screen No. 0 has been read at the
host side.
The system startup waiting time has
not elapsed yet.
The Transmit mode has not been
established.
Not connected to the Support Tool.
The PT model setting and direct con-
nection setting at the Support Tool do
not match the NT631/NT631C.
Memory switch settings do not match. Check the communications setting in the Memory
NT631/NT631C and host are not cor-
rectly connected.
In an RS-422A/485 connection, the
terminator setting is incorrect.
In an NT link (1:N) connection, there
is duplication in the unit numbers.
The power to the NT631/NT631C, NT-
AL001 or host is OFF.
Malfunction due to external noise
The NT631/NT631 has developed
trouble.
Malfunction due to external noise
The touch panel is broken.
The NT631/NT631C changes the
mode when Host Link communica-
tions are used.
When a fault relating to the operation of the NT631/NT631C occurs, find the
symptoms in the table below and respond by following the corresponding
Remedy indicated in the table.
1. Confirm system safety before turning the power ON/OFF or resetting.
2. Do not disassemble the PT for repair or modification.
Cause
Check the connections and make sure that power is
supplied correctly. (3-1-3 Power Supply Connection,
page 33)
Contact your OMRON service center.
This is not an error. Change the screen number from
screen number 0. (Setting the screen number to 0
turns the screen off.)
This is not an error. The display will appear after the
waiting time has elapsed.
Display the System Menu and select the Transmit
mode. (6-6 Transmitting the Screen Data)
Check the installation of the connector cable. (3-2
Connecting to the Support Tool)
Using the PT Configuration settings of the Support
Tool, set the PT model and direct connection settings
that match the NT631/NT631C.
Switch menu of the Maintenance mode, and match
the communications protocol settings for the host and
NT631/NT631C. (6-7 Setting Conditions for Commu-
nications with Host by Using Memory Switches)
Check that the type, length, and installation of the
connector cable match the specifications. (SECTION
4 Connecting to the Host from the RS-232C Port, and
SECTION 5 Connecting to the Host from the RS-
422A/485 Port)
Make the NT631/NT631C and PLC termination resis-
tance settings correctly. (SECTION 4 Connecting to
the Host from the RS-232C Port, and SECTION 5
Connecting to the Host from the RS-422A/485 Port)
Make the settings again so that there is no duplica-
tion. (6-7-4 Setting the NT Link (1:N) Method (Stan-
dard/High-speed), page 158)
Check the power supply.
Carry out grounding work in accordance with the
conditions by referring to 3-1-4 Grounding, page 34.
Contact your OMRON service center.
Carry out grounding work in accordance with the
conditions by referring to 3-1-4 Grounding, page 34.
Test the touch panel with I/O Check in the MAINTE-
NANCE MODE menu. If there is an error, contact
your OMRON service center.
This is an NT631/NT631C specification. When using
a PLC that can also be connected using the NT link
method, use an NT link connection (there is no mode
change with the NT link method).
