OUTPUT s w itch is t u rned
on.
When the prod u ct is set to the
three-phase inp u t mode, isn’t the
po w er distrib u tion line arranged
for the single-phase inp u t?
Confirm the stat u s of the inp u t
po w er phase mode. 2-6

Is the OVP trip point set less than
or eq
u al to the o u tp u t voltage?
Set the OVP trip point to a voltage
greater than or eq
u al to the o u tp u t
voltage.
4-11
Is the OCP trip point set less than
or eq
u al to the o u tp u t c u rrent?
Set the OCP trip point to a c u rrent
greater than or eq u al to the o u tp u t
c u rrent.

Is the remote sensing f u nction
t u rned on?
If yo u are not u sing the remote
sensing f u nction, t u rn off the
sensing s w itch.
4-27
Is the polarity of remote sensing
cable connection reversed? The polarity of the remote sensing
cable may be reversed, or the
ends may be shorted. Check the
load cable.
4-27
Are yo u u sing remote sensing
w ith a long load cable?
Set u p the environment so that the
voltage drop in the load cable is
w ithin the compensation voltage
range (0.6 V for a single line).
4-26
Is the control cable loose in the
external control? Connect it correctly. Chap

Is the external voltage excessive
in the external control? Apply the correct voltage. 5-9
5-13
Is one of the phases of the three-
phase inp
u t open?
The distrib u tion system is
abnormal or one of the phases of
the three-phase inp
u t is open.
Check the distrib u tion system and
the three-phase inp u t cable, and
connect the PAT to an AC po w er
s u pply that matches w ith the
specifications of the PAT.
2-6
Is the internal temperat u re is
abnormally high?
• The overheat protection
f u nction is activated. Check the
operating environment.
• The d u st filter may be clogged,
or the fan may be broken.
Check them.

The ALARM LED
ill
u minates w hen the load
is changed.
Is a large external voltage applied
s
u ch as w ith a battery load?
• The overvoltage protection
f u nction or the overc u rrent
protection f u nction may be
activated. Check them.
• The PAT may be overloaded.
Check the load.

Is the act u al o u tp u t voltage is
higher than the preset voltage
sho
w n on the panel?
Is a special load is connected?
