Device Description
·Connect the consumers with the load outputs (IEC C13, max. 10A).
1.5 Residual Current Type A
This device measures Residual Current type A (also known as fault current) for sinus-
oidal alternating currents and pulsating direct fault currents.
Residual Current is displayed in the web interface, but can also be queried via the
other protocols.
1.6 Residual Current Type B
The Expert Power Control 8041/8045 Models -11/-12/-13/-14 are additionally equipped
with an all-current sensitive Residual Current Monitor Type B (RCMB) from Bender.
This allows sinusoidal AC residual currents, pulsating DC residual currents, smooth
DC residual currents and mixed residual currents to be measured at frequencies of up
to 2000 hz. The Residual Current Monitor Type B gives an extended representation of
the residual currents, in which it can detect the alternating current (RMS) and direct
current (DC) components of the fault current.
Residual Current Type B is displayed as an additional line in the web interface (Control
Panel) under the other electrical values, but can also be queried via the other proto-
cols.
1.7 Overvoltage Protection
The device contains an overvoltage protection. The protection is based on input side
varistors with thermal fuse between phase (L) and neutral (N) to protect 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 flash.
·An invisible flash means that the protection is active, a red flash symbolizes that the
overvoltage protection fails. (Revision 1 device)
·An green flash means that the protection is active, a red flash symbolizes that the
overvoltage protection fails. (Revision 2 device)

11
Expert Power Control 8041/8045 © 2023 GUDE Systems GmbH
Device Description
In addition, the status of the overvoltage protection can be seen on the Webpage
(HTTP) and acquired with SNMP. In the web interface (Control Panel), the proper state
is marked as "OVP operational. Each surge protection module is designed that it can
derive a practical unlimited number of voltage pulses in normal installation environ-
ments. In an environment with many energy rich surge pulses it can result in perman-
ent loss of function due to aging of the overvoltage protection element.
Recovering of the overvoltage protection function can only be performed by the
manufacturer 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.

Event messages are generated when the logic changes. In the sensor configura-
tion the logic can be inverted. So that "High" appears when the input is closed, the lo-
gic is configured as inverted as fabdefault. In protocols with numeric values (e.g.
SNMP or ModbusTCP) a "1" is considered as High, and a "0" as Low.

Device Description
Sensor in web interface
The sensors are automatically detected after connect. This is indicated by the green
LED on the sensor port that is lit permanently. The sensor values are displayed at
the "Control Panel" web page:
A click on the link in the "Name" column opens the display of the Min and Max values.
The values in a column can be reset using the "Reset" button. The "Reset" button in
the name column deletes all stored Min and Max values.
If external sensors with inputs are connected, these are also added on the "Control
Panel" web page:
1.9.1 Calibration
From this firmware version it is possible to store a value offset in the sensor for internal
sensors (Expert Sensor Box) or external sensors. This offset is zero ex works, be-
cause the sensors are normally not calibrated. The offset can be specified by the fol-
lowing commands via Telnet / SSH:
extsensor {port_num} {sen_field} calib set {float}
extsensor {port_num} {sen_field} calib show
For internal sensors (such as the Expert Sensor Box), the internal sensor port is 1.

2 Operating
2.1 Operating the device directly
Port Switching
The current switching state of the output is indicated by the corresponding plain text
displays (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 alloc-
ated.
·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 8041/8045 © 2023 GUDE Systems GmbH
Operating
The web page provides an overview of the switching state, energy measurement val-
ues, as well as the external sensors, provided that they are connected. The text "OVP
operational" indicates that the Overvoltage Protection is working. See chapter Over-
voltage Protection . The number of ports shown depends on the model. When a
single port is clicked at the Expert Power Control 8041/8045, 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. An additional
small clock icon indicates that a timer is active. Timer can be activated by delay, reset
or batch mode.
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 8045 shows the measured values
of the selected port:

19
Expert Power Control 8041/8045 © 2023 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
described in the chapter "Configuration - Power Ports ". The "Close" button dis-
solves 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.

firmware 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 options. 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-sys-
tems.com.
