616. Remote ON/OFF Control
Remote ON/OFF control function is provided. Output ON/OFF is allowed to control without input voltage
ON/OFF, dependent on the condition of CN84 (CNT1, CNT2 and TOG terminal).
Remote ON/OFF control circuit is isolated from input and output.
CNT1, CNT2 and TOG are not connected at time of shipment, so power supply output condition is ON.
617. Sleep Mode
Sleep mode is provided and it contributes to reduction of standby power when all of the following
conditions are satisfied.
・
Output condition is
“
OFF
”
by remote ON/OFF control terminal.
・
Output condition is
“
OFF
”
by communication function when CNT mode is
“
digital CNT
”
.
・
PF signal is
“
High
”
.
・
Protection has not occurred
（
all of the alarm history indicator register are
“
0
”
).
・
The query has not been sent for more than 30 minutes.
In sleep mode, the power supply returns to normal operation by turning remote ON/OFF control to
“
ON
”
or triggering the signal of RS485. Take note that the communication function cannot be used during sleep
mode and power supply cannot receive the signal of RS485. In this case, send the query again.
When a voltage is applied to the output terminal of the power supply from the outside in sleep mode, if the
PF threshold is exceeded, PF signal keeps
“
High
”
. Refer to
“
Communication Manual
”
for details.
