Parker Automation Controller
PAC120
4.5.3 USB Sticks
USB stick users should consider the following points:
• The USB port is mechanically designed to support up to 1,000 plug/unplug operations.
• Pulling off a USB stick during operation is allowed only when no more file operations are being performed. Fail-
ure to comply may render the USB stick useless!
• If a program still has a file open when the USB stick is pulled, you will find it impossible to close the directory that
the file belongs to. In this situation, the system will not respond to any file or directory operation requests because
it would be expected to read from a device that is no longer available. Therefore, before pulling off the USB stick,
you should always ensure that no program still has an open file loaded from the stick.
• Before pulling off the stick, always use the function USB_UMountDisk from the Parker System Library iMX6
• USB sticks can be found under the following path: \media\usbx (x = 1..n number of plugged USB sticks)
• Supported format(s): FAT32

4.5.5 X4 Digital Input and Power Supply
On-board power supply unit
The PAC Controller features an on-board power supply unit (PSU) designed for an input voltage of 24 VDC (18 V ...
32 V). The PSU is protected against reverse polarity. It supplies power to the PAC120's CPU core and to the PACHC
and PACIO modules connected to the E-bus. The modules themselves require their own power supply.
Verify that both the cord and the PSA are externally protected against short circuit and overload triggering at max. 10 A.
