PBZ
Turning On the Power
If an error number is displayed when you press the OUTPUT key
Even if “PASS” is displayed on the screen after the self test completes, an error number
(E001) may be displayed when you press OUTPUT. If this occurs, the input voltage is low, so
the PBZ can not function properly after it turns on. Follow the remedy shown in the following
table.
If “POWER OFF” is displayed
“POWER OFF” may be displayed on the screen while the PBZ is running. If this occurs, the
input voltage is low, so the PBZ can not function properly. Turn the POWER switch off, and
then check the voltage of the input power supply.
Turning the POWER Switch Off
●
Flip the POWER switch to the ( ) side to turn the PBZ off.
When you turn the POWER switch off, “POWER OFF” is displayed on the screen.
Because the PBZ uses its residual power to show the display, it disappears after a few
seconds.
The PBZ saves the panel settings (except the output on/off setting) that were in use
immediately before the POWER switch was turned off. You can restore the PBZ to this saved
state the next time that it starts.
If you switch the settings and then immediately turn the POWER switch off, the settings that
were in use immediately before the PBZ turned off may not be saved.
When the POWER switch is forcibly turned off
The PBZ’s POWER switch is normally turned off manually, but the PBZ is also equipped with
a feature that forcibly turns the POWER switch off. When one of the following situations
occurs, a message appears after the POWER switch turns off. Because the PBZ uses its
residual power to display the message, it disappears after a few seconds.
• The overvoltage or overcurrent protection has been activated.
• A shutdown signal has been received through the external contact.
Error number Message Cause and remedy
E001 INPUT VOLTAGE The input voltage is low, so the PBZ can not function
properly. Turn the POWER switch off, and then check the
voltage of the input power supply. The input voltage range
that can be applied is 90 Vac to 250 Vac.
CAUTION
• After you turn the POWER switch off, wait at least 10 seconds after the fan stops before
you turn the POWER switch back on. Turning the PBZ on too soon after you turn it off can
cause damage to the inrush current limiter circuit, as well as reduce the life of components
such as the POWER switch and the internal input fuses.
