Checking the Power Supply Voltage
Checking Whether an Alarm Has Occurred
This section explains the preliminary checks and analytical tools required to determine the cause of
a problem if one occurs.
• Check the voltage at the power supply input terminals.
• Check the voltage of the sequence input power supply. (+24 VIN Terminal (CN1 pin 7))
• Evaluate the problem using the 7-segment LED display on the front panel and using the operation
• When an alarm has occurred:
• When an alarm has not occurred:
• In either case, refer to 8-3 Troubleshooting for details.
Main-circuit Power Supply Input Terminals (L1, L2, and L3)
Control Circuit Power Supply Input Terminals (L1C and L2C)
If the voltage is outside of this range, there is a risk of operation failure, so be sure that the power
supply is correct.
If the voltage is outside of this range, there is a risk of operation failure, so be sure that the power
supply is correct.
