Preliminary Checks When a Problem Occurs
This section explains the preliminary checks required to determine the cause of a problem if
one occurs.
Checking the Power Supply Voltage
Check the voltage at the power supply input terminals.
Main Circuit Power Supply Input Terminals (L1, L2, L3)
R88D-KT@L
R88D-KT@H
R88D-KT@F
Control Circuit Power Supply Input Terminals (L1C, L2C)
R88D-KT@L
R88D-KT@H
R88D-KT@F
If the voltage is out of range, there is a risk of operation failure. Be sure that the power supply is
within the specified range.
Check the voltage of the sequence input power supply (+24 VIN terminal (CN1 pin 7)).
If the voltage is out of range, there is a risk of operation failure. Be sure that the power supply is
within the specified range.
Checking Whether an Alarm Has Occurred
