9. How to handle troubles
Caution
In the event of an alarm or abnormal condition that cannot be resolved,
immediately stop the operation and contact Teral. or its service
company. Otherwise, it may lead to an accident.
Before the contact, check the status of abnormal condition and the
alarm code No., as well as information shown on the nameplate, and
then let us know the information.
9.1 Alarm
handling
9.1.1
Checking the alarm description
If an alarm occurs, the buzzer sounds, the Failure
indicator lamp on the operation panel blinks, and
the alarm code appears on the display.
Some failures do not generate an alarm
immediately. Instead, the system takes back and
retries the action several times and generates an
alarm only if the failure still persists.
Referring to the “Table 9-1 Alarm code table,”
identify the alarm status and eliminate the cause.
To find out the cause of the problem, refer to “9.2
Troubleshooting.”
If multiple alarms occur at the same time, the
displayed codes are switched every two seconds.

9.1.2 Resetting
alarms
Eliminate the cause of the problem and then press the reset switch.
If the reset switch is pressed before the cause of the problem is eliminated, the alarm cannot be reset.
If multiple alarms occur, the system resets only the alarms whose cause has been removed.
9.1.3
Stopping the buzzer
You can stop a sounding buzzer by pressing the Buzzer stop switch.
The Buzzer Stop Time setting (P200) allows you to specify whether to stop the buzzer automatically after a
specified period or to prevent the buzzer from sounding.
For the setting procedure, refer to “7.5 Parameter setting.”
