Start-up the device
·Connect the two power cords (IEC C19, max. 16A) to the mains supply. The cable
connectors are secured as regards their type against unintentional loosening. They
must be inserted up to the stop, otherwise there is no secure connection. The plug
must not wobble in the socket, or there is no tight connection.
·Plug the network cable into the Ethernet socket (RJ45).
·If required, setup a serial connection to the RS232 port.
·Insert the optional external sensors into the sensor connectors.
·Connect the consumers with the load outputs (IEC C13, max. 10A).
1.5 Dual-Circuit Characteristics
The Expert Power Control 8221-1/8226-1 has two different input circuits (Banks A and
B). Therefore the mains supply A ( IEC C20, max. 16 A ) feeds the current to the load
outputs A1 to A6 (IEC C13, max. 10 A), resp. mains supply B feeds the current to the
load outputs B1 to B6 (IEC C13, max. 10 A ) . The electronics of the device works when
one of the two input circuits is supplied .

9
Expert Power Control 8221/8226 © 2022 GUDE Systems GmbH
Device Description
Twin Port
Two ports of different Banks but with the same number can be combined to a "twin port".
Then one port always participates in the switching status of the other port. In the screen-
shot the ports A1 and B1 are combined, symbolized by the chain link icon. The "Con-
nect twin port" option can be found in the chapter "Configuration - Power Ports" .
Currentless Bank
If a bank is not receiving enough power smaller 70 V), a red "L" appears in the front
panel display, while a operating power supply shows a green " L". Upon entry of the cur-
rent loss all relays are switched off by the electronics, but the "On" and "Off" LEDs still
show the state of the relays when the supply was active. This is symbolized by the
flashing of the LEDs.
1.6 Overvoltage Protection
The device contains an overvoltage protection at each of the banks. The protection is
based on input side varistors with thermal fuse between phase (L) and neutral (N) to pro-
tect the internal electronics and power ports with failure detection (permanently triggered
thermal fuse). The state of the protection is indicated on the front panel by a green or red
flash. A green flash means that the protection is active, a red flash symbolizes that the
overvoltage protection fails. In addition, the status of the overvoltage protection can be
seen on the Webpage (HTTP) and acquired with SNMP. Each surge protection module
is designed that it can derive a practical unlimited number of voltage pulses in normal in-
stallation environments. In an environment with many energy rich surge pulses it can
result in permanent loss of function due to aging of the overvoltage protection element.
Recovering of the overvoltage protection function can only be performed by the manu-
facturer of the device. In the normal case, the device will continue to work even after the
failure of the protective function.
A signaling via E-Mail, Syslog or SNMP trap occurs only once during operation, ex-
actly at the moment in which the protection fails. In addition, at the start up of the device
a message is generated, when the overvoltage protection is not active.

2 Operating
2.1 Operating the device directly
Port Switching
The current switching state of the output is indicated by the corresponding plain text dis-
plays (port LEDs). If the green "on" LED is lit, the port is switched on, if the red "off" LED
is lit, the output port is switched off. The buttons "Select" and "Ok" are located on the
device. If you press "select", you can select the following modes one after the other (in
the front panel configuration you can deactivate the modes "All on" or "All off").
1. All on (PALL in the display): All LEDs flash green. If you press the "Ok" button for
2.5 seconds, all ports are switched on.
2. All off (PALL in the display): All LEDs flash red. If you hold the "Ok" button for 2.5
seconds, all ports are switched off.
3. If you press "Select" again, the LED for the first output starts flashing, i.e. the output
is selected. Press "Select" again to select the next output. Pressing and holding the
"Ok" button for one second will toggle the state of the selected output.
If the ports are already "All on" or "All off", the corresponding mode is skipped.
Display Information
If no port is selected manually, repeatedly pressing the "ok" button will show the IP-ad-
dress and the values of the external sensors on the display.
Status-LED
The Status LED shows the different states of the device:
·red: The device is not connected to the Ethernet.
·orange: The device is connected to the Ethernet and waits for data from the DHCP
server.
·green: The device is connected to the Ethernet and the TCP/IP settings are allocated.
·periodic blinking: The device is in Bootloader mode.
2.2 Control Panel
Access the web interface: http://"IP-address" and log-in.

Expert Power Control 8221/8226 © 2022 GUDE Systems GmbH
Operating
The web page provides an overview of the switching state, energy measurement values of
the banks "A" and "B", as well as the external sensors, provided that they are connec-
ted. When a single port is clicked at the Expert Power Control 8221-1/8226-1, a panel
with buttons to control a single port appear:
The Port icon is green when the relay is closed, or red in the open state. If a bank has
no voltage, the state is represented by a gray Port icon. An additional small clock icon
indicates that a timer is active. Timer can be activated by delay, reset or batch mode.
Two outputs configured as twin ports are connected by a chain icon.
An activated Watchdog is represented by an eye icon. An "X" means, that the address
that should be observed, could not be resolved. Two circular arrows show a booting
status.
In addition to the panel, the Expert Power Control 8226-1 shows the measured values
of the selected port:

17
Expert Power Control 8221/8226 © 2022 GUDE Systems GmbH
Operating
The ports can be switched manually with the "On" and "Off" buttons. If the port is turned
on, it can be turned off by pressing the "Reset" button, until after a delay it turns itself on
again. The delay time is determined by the parameter Reset Duration, which is de-
scribed in the chapter "Configuration - Power Ports ". The "Close" button dissolves
the panel again.
Batchmode
Each individual port can be set for a selectable period of time to the state "switch on" or
"switch off". After the selected time they are automatically switched to the second
preselected state.
Optionally the device can be switched via a Perl script or external tools like wget. More
information is available on our support wiki at www.gude.info/wiki.
2.3 Maintenance
The actual device generation with IPv6 and SSL allows all maintenance functions in the
web interface to be carried out on the Maintenance Page .
Maintenance in the web interface
The following functions are available from the maintenance web page:
·Firmware Update
·Change the SSL certificate
·Load and save the configuration
·Restart the device
·Factory Reset
·Jump into the Bootloader
·Delete the DNS cache
Upload Firmware, Certificate or Configuration
On the Maintenance Page , select the required file with "Browse .." in the sections
"Firmware Update", "SSL Certificate Upload" or "Config Import File Upload" and press
"Upload". The file is now transferred to the update area of the device and the contents
26

Expert Power Control 8221/8226 © 2022 GUDE Systems GmbH
Operating
are checked. Only now, pressing the "Apply" button will permanently update the data, or
abort with "Cancel".
Only one upload function can be initiated with a reboot, eg. you cannot transmit firm-
ware and configuration at the same time.
If after a firmware update, the web page is not displayed correctly anymore, this may
be related to the interaction of Javascript with an outdated browser cache. If a Ctrl-F5
does not help, it is recommended that you manually delete the cache in the browser op-
tions. Alternatively, you can test start the browser in "private mode".
During a firmware update, old data formats are sometimes converted to new struc-
tures. If an older firmware is newly installed, the configuration data and the energy
meters may be lost! If the device then does not run correctly, please restore the factory
settings (e.g. from the Maintenance Page ).
Actions in Bootloader mode
If the web interface of the device is no longer accessible, the device can be put into
Bootloader mode (see chapter Bootloader activation ). The following functions can be
executed using the GBL_Conf.exe application:
·Set IPv4 address, net-mask and gateway
·Turn HTTP password on and off
·Turn IP-ACL on and off
·Factory Reset
·Allow jump from firmware to bootloader
·Restart the device
For devices with relays, entering or exiting the bootloader mode does not change
the state of the relays as long as the operating voltage is maintained.
The GBL_Conf.exe program is available free of charge on our website www.gude.info and
can also be found on the enclosed CD-ROM.

Operating
Interface GBL_Conf
To check the network settings with GBL_Conf.exe, start the program and choose "All
Devices" in the "Search" menu. From the list select the appropriate device. The lower
part of the left half of the window now shows the current network settings of the device. If
the IP address is displayed with the default settings (192.168.0.2), either no DHCP
server is present on the network, or there could be no free IP address assigned to it.
·Activate the Bootloader Mode (see Chapter Bootloader Mode) and choose in menu
"Search" the item "Bootloader-Mode Devices only"
·Enter the desired settings in the edit window and save them with "Save Config".
·Deactivate the boot loader mode for the changes to take effect. Select again "All
Devices" in the "Search" menu of GBL_Conf.exe.
The new network configuration is now displayed.
Changing the configuration with gbl_conf.exe is explicitly only allowed in bootloader
mode!
Factory Reset
The device can be reset to the factory default via the web interface from the Maintenance
Page or from the Bootloader mode (see chapter Bootloader activation ). All TCP/IP
settings are reset in this operation.
If a unit is set to factory defaults, an uploaded certificate or updated firmware will be
preserved.

Operating
2.3.1 Maintenance Page
This section provides access to important functions such as Firmware Update or Restart
Device. It is advisable to set an HTTP password for this reason.
Firmware Update: Start a firmware update.
SSL Certificate Upload: Saves your own SSL certificate. See chapter "SSL " for the
generation of a certificate in the right format.
Config Import File Upload: Loads a new configuration from a text file. To apply the new
configuration, a "Restart Device" must be executed after the "Upload".
Config File Export: Saves the current configuration in a text file.
Saving the configuration should only be carried out in an SSL connection, since it
contains sensitive password information (even if it is encrypted or hashed).
Restart Device: Restarts the device without changing the status of the relays.
Some functions such as a firmware update or changing of the IP-address and HTTP
settings require a restart of the device. A jump to the boot loader or a restart of the
device lead by no means to a change of the relay states.
Restore Fab Settings and Restart Device: Performs a restart and resets the device to
factory default .
