POINT
*1 :
Overcurrent protection
The overcurrent protection device shuts off the 5V, 24 V DC circuit and
stops the system if the current flowing in the circuit exceeds the specified
value.
When this device is activated, the power supply module LED is switched
OFF or dimly lit. In this case, remove any cause of overcurrent and start
up the system.
*2 :
Overvoltage protection
The overvoltage protection device shuts off the 5 V DC circuit and stops
the system if 5.5 to 6.5 V voltage is applied to the circuit.
When this device is activated, the power supply module LED is switched
OFF. In this case, switch OFF, then ON the input power to restart the
system.
The power supply module must be changed if the system is not booted and
the LED remains OFF.
*3 :
Allowable momentary power failure time
This value indicates the momentary power failure time allowed for the
PLC CPU and varies according to the power supply module used with the
PLC CPU module.
The allowable momentary power failure time for a system in which an
A1S63P is used is defined that it starts when the primary power supply of
the 24 V DC stabilized power supply of the A1S63P is turned OFF and lasts
until the 24 V DC becomes less than the specified voltage (15.6 V DC)
