E101 CALIBRATION DATA An error was detected in the calibration values.
E102 EEPROM DATA An error was detected in the backup data.
E901 INTERNAL ERROR An error was detected in the internal system.
If you initialize the PBZ-SR to its factory default settings, you need to set the number of
parallel operation units and the remote sensing on/off setting again. See "Initial Settings" on
page 10, and set the number of parallel operation units installed in the PBZ-SR and the
remote sensing on/off setting.
Message Cause and remedy
There is an error in the calibration values that are stored
in non-volatile memory. The PBZ-SR must be calibrated
properly. If this error number (E101) appears even after
you have calibrated the PBZ-SR, it may be
malfunctioning.
There is an error in the backup data that is stored in
nonvolatile memory. You can clear this error by starting
the PBZ-SR with the factory default settings. For details,
see “List of Factory Default Settings” in PBZ series
User’s Manual.
There is an execution error in the internal system.
Restart the PBZ-SR.
If “POWER OFF” is displayed
“POWER OFF” may be displayed on the screen while the PBZ-SR is running. If this occurs,
the input voltage is low, so the PBZ-SR can not function properly. Lower the POWER switch
lever to turn the power off, and then check the voltage of the input power supply.

Turning Off
Lower the POWER switch lever to turn the power off.
“POWER OFF” is shown on the display for a few seconds and disappears.
After you turn the POWER switch off, wait at least 5 seconds after the fan stops before you
turn the POWER switch back on. Turning the PBZ-SR 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.
• The PBZ-SR series stores the panel settings (excluding output on/off condition)
immediately before the POWER switch is turned off. If you turn the power on, the PBZ-SR
starts in the same state as it was in the last time that it was turned off. If the POWER switch
is turned off immediately after changing the settings, the last settings may not be stored.
• If you want to turn off the POWER switches of the individual PBZ power supplies before the
POWER switch of the PBZ-SR, turn off the slave units first.

WARNING
See
Connecting the Load
This chapter describes how to connect a load to the PBZ-SR.
Connecting the Load Cable
Selecting the Load Cable
To prevent the possibility of fire.
• Use a load cable with sufficient current capacity with respect to the rated output
current of the PBZ-SR series.
Possible electric shock.
• Use load cables whose rated voltage meets or exceeds the PBZ-SR’s isolation
voltage (500 Vdc).
p. 3
The load cables that you use must have a current capacity that allows the PBZ-SR’s rated
output current to flow. If you use load cables whose capacity meets or exceeds the rated
output current, even if the load is shorted, the cables will not be damaged. Use wires that
have diameters that correspond to the output current to connect to the load.

You can also use the optional low inductance cable (TL02-PLZ, TL03-PLZ, LIC40-2P1MM6M6 or LIC40-2P2M-M6M6).
A cable’s temperature is determined by the resistive loss based on the current, the ambient
temperature, and the cable’s external thermal resistance. The above table shows the current
capacity of heat-resistant vinyl cables that have a maximum allowable temperature of 60 °C
when one of the cables is separated and stretched out horizontally in air in an ambient
temperature of 30 °C. The current capacity must be reduced under certain conditions, such
as when vinyl cables that have a low heat resistance are used, when the ambient
temperature is 30 °C or greater, or when cables are bundled together and little heat is
radiated.

Influence of Cables
When you use the PBZ-SR, you must wire the load and configure the response setting
correctly and reduce the inductance. If these conditions are not met, the PBZ-SR may
oscillate or become unstable.
Load cables and inductance
Load cables have inductance L. If current I changes quickly, a large voltage is induced on
both ends of the cable. This voltage is applied to both the PBZ-SR and the load. The load
cable’s inductance L and voltage E that is induced according to the changes in current I
(hereafter referred to as the induced voltage) are expressed as follows:
PBZ-SR 13
Generally, a cable’s inductance is 1 μH per meter of cable. If 2 meters of cable are used to
wire the load (the total length of the cables that are connected to the OUT terminal and the
COM terminal) and the current change is 10 A/μs, the induced voltage is 20 V.
Page 14
Connecting the Load Cable
See
How to reduce the effect of wiring
p. 3
• You can reduce the inductance of load cables by using the optional low inductance
cables (TL02-PLZ, TL03-PLZ, LIC40-2P1M-M6M6 or LIC40-2P2M-M6M6).
• If fast transient response is not required, increase the response setting.
The value of I/T is reduced, so even if you can’t reduce the load cable’s inductance,
you can reduce the induced voltage. For details on the response setting, see “Response
Setting” in PBZ series User’s Manual.
• Use the shortest cables possible to wire the load, and twist them.
When Connecting Capacitive or Inductive Loads
Oscillation may occur when the PBZ-SR is connected to a capacitive load in CV mode or
when the PBZ-SR is connected to an inductive load in CC mode. To remedy this problem,
increase the response setting or use the soft start and soft stop features.
For details on each feature, see the following sections in the PBZ series User’s Manual.
• For CV mode and CC mode, see “CV/CC Mode.”
• For response settings, see “Response Setting.”
• For soft start and soft stop, see “The Output Soft Start and Soft Stop Features.”
When Connecting Battery Loads
If you connect a device to the OUTPUT terminals that can supply power, like a battery, the
PBZ-SR is a load to the device. In this situation, there is a limit to the amount of power that
the PBZ-SR can consume. When the PBZ-SR’s sink power becomes too large, it limits its
output current (the sink current to the PBZ-SR) so that the sink power reduces to a constant
value.

Using Remote Sensing
WARNING
WARNING
CAUTION
Remote sensing is a feature that is used to switch the voltage measurement point of CV/CC
mode and the voltage feedback point of CV mode.
When remote sensing is enabled, the voltage measurement point of CV/CC mode and the
voltage feedback point of CV mode are switched from the rear panel OUTPUT terminals to
the contact points of the sensing terminals. Connecting the sensing terminals to the load (1)
reduces the influence of the voltage drop caused by the resistive component of the load wires
and by the load current and (2) allows measurement and compensation of the output voltage
across the load. The compensation of the output voltage is effective to the voltage drop that is
1.8 V or less for a single line.
Remote sensing of CV mode has a protection feature. Even if the remote sensing wires are
connected in reverse, shorted, or disconnected, the output voltage in CV mode is limited
within the specified voltage ± approximately 3.6 V. When the connection is fixed, the
protection feature automatically recovers.
To avoid electric shock and damage to the PBZ-SR’s internal circuits, observe the
following precautions.
• Never wire the sensing terminals while the POWER switch is turned on.
• For sensing cables, use cables whose rated voltage is higher than the PBZ-SR’s
isolation voltage (500 Vdc).
Connecting the Sensing Cables
To use remote sensing, connect sensing cables to the sensing terminals of the PBZ-SR.
Risk of burns.
• The rear panel may become hot during operation. Before you touch the rear panel,
turn the POWER switch off, and allow a sufficient amount of time for the rear panel
to become cool.
• If the remote sensing cables come loose while remote sensing is in use, the PBZ-SR and
load may break. Be sure to connect the cables securely.
• If you are not using remote sensing, be sure to attach the two short bars to the sensing
terminals.

Connect by referring to the following information.
When remote sensing is enabled, if the sensing terminals are shorted, opened, or are
wired in reverse, the sensing protection is activated, and the output voltage in CV
mode is limited within the specified voltage ± approximately 3.6 V. When the
connection is fixed, the protection feature automatically recovers. Do not leave the
PBZ-SR while the sensing protection is activated.

Example of PBZ20-100 SR
By using an external signal, you can create a bipolar amplifier that amplifies the input signal
that the PBZ-SR receives through EXT SIG IN (BNC terminal). You can set the gain, the
polarity (inverted or not inverted), and the offset of the amplifier. For details on how to use an
external signal source, see “Using the EXT SIG IN Signal (External Signal Source)” in the
PBZ series User’s Manual.
