The built-in fans will stop when all output modules are turned off
by the Global inhibit function.
5
AUX is available even when outputs are turned off by Global
inhibit.
6
If the voltage or the current which exceeds the value in table 4.2
were supplied into GI2 pin, the output might not be generated
correctly.
7
Start time is 1,000ms max.

4.10 Isolation
¡
When the Hi-Pot test for the receiving inspection, etc is conduct-
ed, the voltage should be increased gradually. Also, the voltage
should be decreased gradually by using the dial. Please do not
use the Hi-pot tester which has the timer because it might gener-
ate unwanted high voltage when timer is on.
¡
When the isolation test between the input and the output, the input
and the FG and the output and the FG is conducted, all outputs
and terminals for all functions should be shorted.
4.11 Alarm
¡
The unit has two typs of alarm below. Table 4.3 is the detail of the
alarm.
1
PR: abnormal input voltage, fan alarm
2
LV: drop and shut-off of output voltage
Table 4.3 Explanation of alarms
Alarm
Output of alarm
PR
When the input voltage is
abnormal (low input voltage) or
the fan stops, the alarm signal is
generated from CN1.
Open collector method
Good:Low (0.5Vmax at
5mA)
Fail:High (50Vmax)
LV
When the rated output voltage
decreases or stops, the alarm
signal is generated from CN3.
Note:
When the overcurrent protection
activates, the alarm will be
unstable.
Open collector method
Good:Low (0.5Vmax at
5mA)
Fail:High (50Vmax)

¡
Please note the followings when you use the alarm (LV signal).
1
If the output voltage is turned off by the remote ON/OFF circuit,
the LV signal will get “High”.
2
The LV signal may get “High”, if the output voltage drops to 40%
or less of the rated voltage.
¡
The LV signal (Alarm) circuit is isolated from input, output, FG and
other function terminals.
