Items to check and corrective actions

The breaker of the powe supply
trips

The protection function of the power supply (OVP or OCP) may have been
activated. Please confirm the setting of the protection function of the power
supply. It also may happen when the current doesn't flow into the DUT
(battery) or when at no load, it is likely to become this operation.

p. 38

Immediately after charging

begins,

is displayed on the front panel.

The overvoltage protection may have been activated.
Is the DUT connected correctly?
Is the voltage sensing position correct?
Is the charging circuit cut off by the battery protection circuit (BMS)?
Is the internal impedance of the DUT high causing the voltage to increase due
to the charge current?

Immediately after discharging

begins,

is displayed on the front panel.

The undervoltage protection may have been activated.
Is the DUT connected correctly?
Is the voltage sensing position correct?
Is the internal impedance of the DUT high causing the voltage to decrease due
to the discharge current?

When the power failure of AC power line is occured longer than 50 ms or any
voltage error is occured, the alarm (AC_OFF alarm) activates. Moreover, if there
is a regenerative device on the same power line and the waveform of the power
line confirms large distortion, it may cause to malfunction of the alarm
operation or to fluctuate the measurement value. Install the line filter or the
like, if necessary.

It displays

on the

front panel.

The over heat protection function of the power circuit may have been
activated.
It may be concerned for the case such as when the ambient temperature
exceeds the operating temperature, the air intake vent and the exhaust vent
are blocked, the failure of the cooling fan, the clogged dust filter, etc.
When the LED illuminates even any abnormal operation environment is found,
stop the operation immediately and contact Kikusui distributor/agent.

It displays

on the

front panel.

The alarm was occurred in the connected Electronic load. Confirm whether the
protection function (such as "OPP") of the Electronic load is being set properly.
Is the power of the Electronic load turned on?

It displays

on the

front panel.

Is the setting of an external analog control of the connected Electronic load
properly arranged?
Is the flat cable correctly connected?
Is there any abnormality found in the DUT cable and the DUT (battery)?
When the value of discharge exceeds the rated power of the Electronic load, it
may become in the state of alarm.

Is the DUT connected correctly? Is the charging circuit cut off by the battery
protection circuit (BMS)?
The initial current (load check current that is smaller than the set current) for
checking the DUT status is not flowing when attempting to start a charge,
pattern or IV characteristics test.
