8.9 Setting Memory
Settings are backed up and the settings that were applied the previous time the BP4620 was powered
off can be restored the next time is powered on. However, the selected response characteristics are
not saved. Moreover, among the various settings, the basic settings (operation mode, DC,
superimposed AC, output limiters) can be saved to store/recall memories No. 1 to No. 30, and the
saved settings can be called and used.
The store/recall memory call operation is possible only when the output is off.
8.10 Protective Functions
Output overload: If output voltage over, output current over, or internal power loss
over is detected, overload is displayed on the panel screen, and the
output voltage or current is reduced. If the overload status continues
10 or more seconds, the output is switched off.
Power supply anomaly: Upon anomaly detection, the output and power are both switched off.
Internal overheating: Upon anomaly detection, the output and power are both switched off.
Operation panel anomaly: Upon detection of an operation panel anomaly such as the operation
panel being disconnected from the main unit, the output and power
are both switched off.
