● How to Connect with PSA-24
When it is necessary to connect PSA-24 and monitor the status data of the power supply via
RSEL, setting of the number of PSA-24 unit to be connected should be established in Other
Parameter No. 61 “Number of Power Supply Units”.

When using the PC teaching software, select “Monitor (M)”
→ “Power Supply Unit Data (P)”
after the parameter setting is done, and the power supply unit data should be displayed.
[Status data]
The status data available for monitoring is as listed below.
Item Details
Output Voltage
Output voltage AD converted value. As this power source fluctuates the
output voltage, the output voltage monitored value changes from
moment to moment. Note that it is not an error.
Supplement Coil
Voltage
Control power voltage inside power source AD converted value. It
changes in response to the load on output voltage side as it does for
the output voltage, which is not an error.
Peak Hold Voltage
Output voltage AD converted value. Comparison is performed every
time AD conversion is executed and the maximum voltage is saved.
Output Current Output current AD converted value. It shows the transient value.
Peak Hold Current
Output current peak value. Comparison is performed every time AD
conversion is executed and the maximum current is saved.
Load Ratio
It is the value expressed in percentage for the ratio of output current
integral value and the rated output current used for overload judgment
internally. If this value exceeds 100%, an overload error should be
generated and output voltage will be cut off.
Peak Hold Load Ratio
Comparison is performed every time overload calculation is executed
and the maximum load ratio is saved.
Fan Revolution Speed
It is the value of number of fan revolution calculated by pulse signal
input from the fan.
PCB Temperature
It is the AD converted value of the temperature sensor around the
secondary side output capacitor.
Total Conducting Time
It is the time the values saved in the internal memory regularly were
integrated by conducting time was counted in CPU.

The background color should change depending on the status of the acquired status of the
power supply unit.
Auxiliary winding voltage : Yellowish green when 15V or more and white when 10V or less
Load factor
: Yellowish green when 330W with fan equipped and white when
220W with no fan equipped
Fan rotating speed : Gray when no fan equipped, white when fan in normal operation,
yellow when in warning and red when error
When it is necessary to output the monitoring information from the I/O, setting should be
established in I/O Parameter No. 851 “Data I/O Output Setting 01 Data Specifications”. Set the
output data type in bit 00 to 03 (PSA-24: 1) and select the output data items in bit 08 to 15.
