The industrial PC option "ACU UPS Control Unit" in combination with a battery/capacitor
pack extends the industrial PC (IPC) by one UPS function.The ACU UPS software controls
the behaviour of the IPC in this process as soon as the hardware identifies a supply voltage
failure.
The ACU UPS control unit is a factory set pre−equipment if you chose this option when
placing your purchase order. However, it can also be upgraded later on by Lenze service
personnel.
If you purchased the preinstalled operating system on a storage medium at Lenze, the ACU
UPS software is already installed and configured according to your hardware.
Alternatively, you can find the software on the driver CD for your IPC. Then, install the
software as described in the chapter "Software Installation". (¶ 17
1.1Operating mode
Software description
Operating mode

During the boot phase of the operating system, the ACU UPS is in a permanent buffer
operation which means that it already provides protection against data loss in the boot
phase, even before the ACU software has started.
The ACU software starts automatically after the operating system has been booted and
monitorsthe voltage supply from the background until it is closed along with the operating
system.

In the case of a voltage failure, the ACU UPS takes charge of the IPC supply. The remaining
time to the IPC shutdown is displayed on the desktop. (¶ 14).

Start
After the IPC has been booted, the software starts automatically and then runs in the
background. A symbol pops up in the information bar.

)Note!
If an L−force Controller is delivered with ACU UPS but without a battery pack,
the ACU UPS software is installed but UPS support is deactivated. In this case,
there will be no ACU symbol in the information bar of the Windows task bar.
In the "ACU Control" registry, UPS support can be(¶ 12)activated and
deactivated.

control unit until shutting down the IPC. This period of time
must be shorter than the delay time (^ 12) plus the period of

Example:
The IPC can be supplied for 100 s by the battery pack and needs
a maximum of 20 s for a safe shutdown.
Delay time = 100 s
Time before shutdown = < 80 s
While the ACU software counts down the seconds until the IPC is shut down after a voltage
failure, an external program can be started.

storage medium.
In other cases, start the setup program on the program CD and follow the instructions of
the setup assistent.
)Note!
After the ACU UPS software has been reinstalled, UPS functionality is
deactivated for versions V3.x/V4x and activated for version V2.x.
