1. Move the cursor to the command line
of “I LIMIT(A) = ”. I LIMIT(A) = 0.00_ DELAY(S) = 0.0
3. Press 4 , then press ENTER to change I LIMIT(A) = 4_ DELAY(S) = 0.0
the value to “4.00” .
3. The cursor moves to the command line
of “DELAY(S) = ” automatically. I LIMIT(A) = 4.00 DELAY(S) = 0.0_
4. Press 1 , ENTER to change the
value to “1.0”. I LIMIT(A) = 4.00 DELAY(S) = 1.0_
1. When “I LIMIT (A) = 0” it means the limitation of output current is
equal to specification.
2. DELAY time is valid for eliminating transient current spike, but not
work when the output current is over specification. The time
resolution is 0.5s.
3.5.5 OUTPUT RELAY
There are relays on the output of the AC Source for connecting the load. When the output
relay is “ON”, it means it is closed in spite of the output status of the AC Source is in QUIT
mode. When the output relay is “OFF”, it means it is closed only as the output status is in
RUN mode. If the output status is in QUIT mode, the output relay will be opened. Users
can set OUTPUT RELAY on SETUP functional list (see 3.5).

1. Move the cursor to the command of OUTPUT RELAY. OUTPUT RELAY=OFF_
2. Turn the RPG to set it to ON, then press ENTER.
A click will sound from the AC Source when the OUTPUT RELAY= ON
output relay is activated.
Before powering off, please confirm if the AC SOURCE is outputting
voltage. For ensure the life of the AC SOURCE, it is prohibited strongly
to power off under outputting status.
