1.5 Dual-Circuit Characteristics

The Expert Power Control 8221-1/8226-1 has two different input circ uit s (Banks A and B). Therefore the mains supply A ( IEC C20, max . 16 A ) feeds the current t o t he load outputs A1 t o A 6 (IEC C13, max. 10 A), resp. mains supply B feeds the current t o t he load outputs B 1 t o B 6 (IEC C13, max . 10 A ) . The elect ronics of the device works when one of t he t wo input circuit s is supplied .

8

Device Description

Twin Port

Two ports of different Banks but with t he same number can be combined to a "twin port". Then one port always participates i n t he swit c hing status of the other port. In the sc reenshot t he ports A1 and B1 are combined, symboliz ed by the chain link ic on. The "Connect t win 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 s hows a green " L". Upon entry of the current loss all relays are switc hed off by t he elect ronics , but t he "On" and "Off" LEDs still show the state of the relays when the supply was active. This is s ymbolized by t he flashing of the LEDs.

1.6 Overvoltage Protection

The device c ontains an overvoltage protect i on at each of the banks. The protection is based on input s ide varistors with thermal fuse between phase (L) and neutral (N) to protect the internal elect ronics and power ports with failure detection (permanently triggered thermal fuse). The state of the protecti on is indic ated on the front panel by a green or red flash. A green fl as h means t hat t he protection is ac tive, a red flash symboliz es that the overvoltage protection fails. In addition, the status of the overvoltage protection can be seen on the Webpage (HTTP) and acquired with SNMP. Eac h surge protection module is designed that it can derive a pract ical unlimited number of voltage pulses in normal installat ion 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 t he overvolt age protection function can only be performed by the manufacturer of the device. In the normal cas e, t he device will continue to work even after the failure of the protective funct i on.

A s ignaling via E -Mail, S yslog or SNMP trap occ urs only once during operation, exactly at t he moment in which the protection fails. In addition, at the st art up of the device a message is generated, when the overvoltage protection is not ac t ive.

Operating

The web page provides an overview of the switching st at e, energy measurement values of the banks "A " and "B", as well as the external sensors, provided that they are connected. When a single port is clicked at the Expe rt Po wer Control 8221-1/8226-1, a panel with buttons to control a single port appear:

The Port icon is green when the relay is c los ed, or red in the open st ate. If a bank has no voltage, the state is represented by a gray P ort icon. An additional small clock i c on 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 acti vated Wat chdog is represented by an eye icon. A n " X" means, that the address that s hould be observed, could not be resolved. Two circular arrows show a booting status.

In add ition to the panel, the Expert Power Control 8226-1 shows the measured values of the selected port:

The ports c an be switched manually wit h the "On" and "Off" buttons. If the port is t urned on, it c an be turned off by pressing the "Reset " butt on, unti l after a delay it turns it self on again. T he delay time is determined by the parameter Reset Duration, which is desc ribed in the chapter "Configuration - Power Ports ". The "Close" button diss olves the panel again.

23

Batchmode

Each indivi dual port can be set for a selectable period of tim e t o t he st at e " switch on" or "swit ch off" . A fter the select ed ti me t hey are automatically switched to t he sec ond preselected stat e.

On the Maintenance Page , s elec t t he required file with " B rowse .." in the sec t i ons "Firmware Update", "S SL Certificate Upload" or "Config Import File Upload" and press "Upload". The file is now transferred to the update area of the devic e and the contents are checked. Only now, pressing the "A pply " button will permanently update the data, or abort with " Cancel".

Only one upload funct ion c an be initiated with a reboot, eg. you cannot transmit firm-

ware and configuration at t he s ame ti me.

If after a firmware update, the web page is not displayed c orrectly any more, this may

be related to the interacti on of Javascript with an outdated browser cache. If a Ctrl-F5 does not help, it is recomm ended that you manually delete the cache in the browser options. A l t ernatively , you c an tes t start t he browser in "privat e mode".

18

Acti ons i n Bootloader mode

If t he web interfac e of the device is no longer acces sible, the device can be put into Bootloader mode (see chapter Bootloader activat ion ). 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

16

Operating

Interface GBL_Conf

·

Factory Reset

·

Jump into the bootloader (can be switc hed on and off)

·

Restart the devic e

For devices with relays , entering or exiting the bootloader mode does not c hange the st ate of the relays as long as t he 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 enclos ed CD-ROM.

To check the network settings with GBL_Conf.exe, start the program and choose "All Devices" in the "Search" menu. From the list s elec t the appropriate device. The lower part of the left half of the window now shows the current network s ettings of the device. If the IP address i s dis play ed with the default s et t ings (192.168.0.2), either no DHCP server is present on the network, or there could be no free IP address ass i gned to it.

·

Activate the Bootloader Mode (see Chapter Bootloader Mode) and choose in menu

"Search" t he it em " B ootloader-Mode Devices only"

·

Enter the desired settings in the edit window and save them with "Save Config".

2.3.1

Maint en a n c e Page

This section provides access to important functi ons such as Fi rmware Update or Restart Device. It is advis able to s et an HTTP password for this reason.

Firmware Update: S tart a firmware update. SSL Certificate Upload: S aves y our own SS L c ertificate. S ee c hapter "SSL " for the

generation of a certificate in t he right format. Config Import File Upload: Loads a new confi guration from a text file. To apply t he new

Saving the configuration should only be c arried out in an SS L c onnection, since it contains sensitive password information (even if it is encrypted or hashed).

Restart Device: Rest arts the device without changing the status of the relays.

Some functions s uch as a firmware update or changing of the IP-address and HTTP sett ings require a restart of the device. A j ump to t he boot loader or a restart of the device lead by no means to a change of the relay st at es .

Enter Bootloader Mode: Jumps into bootloader mode, where additional settings can be made with GBL_Conf.exe.

Flush DNS Cache: All entries in t he DNS cache are discarded and address resolutions are requested again.

2.3.2

Configu ratio n Management

The device configuration can be saved and restored in the maintenance area .

The "Confi g File E xport" function can be used to save t he current configuration as a text file. The syntax us ed in the configuration file corresponds to t he comm ands of the Telnet console. If the configuration of a devi c e is to be restored from a text file, load the file with "Upload" and restart the device with "Restart Device".

Saving the configuration should only be c arried out in an SS L c onnection, since it contains sensitive password information (even if it is encrypted or hashed). For the same reasons, it i s advi s able to c arefully handle the generated configuration files when archiving.

18

Editing the configurati on fi le

It is poss i ble to c us tomize a s aved configuration file with a text edit or for your own needs. For example, one sc enario would be to use a script language to automate t he creation of many c us t omi z ed versions of a configuration, then equip a large number of devices wit h an individualized configuration. A lso Upload and rest art with CGI commands can be done in sc ripting languages. Wit h use of the comment s i gn "#" y ou c an quick ly hide single commands or add personal notes .

If you modify a c onfiguration file manually, it is not always c l ear which limits are allowed for parameters. A fter uploading and restarting, commands with invalid parameters are ignored. Therefore, the generated configuration includes comments describing the boundaries of the parameters. Where "range:" refers to a numeric value, and "len:" t o a t ex t parameter. E. g:

email a u th set 0 #rang e: 0..2 email u s er set "" #len : 0..10 0

The command "syst em fabsetti ngs" from the beginning of a generated configuration file brings the device into t he factory state, and then executes the individual commands that modify the configuration state. It may be desirable to make the changes relative t o t he current configuration, and not out of the fact ory state. Then the "s yst em fabsettings" should be removed.

Confi gurati on via Telnet

19

Operating

The configuration files can in principle also be transferred in a Telnet session, but then the sett i ngs are changed during operation, and not c ompletely when restarting, as it would have been the case with an upload. It can happen that events are triggered at the same tim e as t he devic e is configured. One should therefore:

a) dis able the function b) c ompletely parametrize c) reactivate the funct i on

An example:

email e n abled s et 0 email s e nder se t "" #len: 0.. 100 email r e cipien t s e t "" #len: 0.. 100 email s e rver se t "" #len: 0.. 100 email p o rt set 25 email s e curity set 0 #range: 0..2 email a u th set 0 #rang e: 0..2 email u s er set "" #len : 0..10 0 email p a sswd ha sh set "" #len : 0..10 0 email e n abled s et 1 #range: 0 ..1

Configuration

3 Configuration

TCP/I P configurati on by DHCP

After switching on the device is scanning on the Ethernet for a DHCP server and requests an unused IP address. Check t he IP address that has been assigned and adjust if necessary, that the same IP address is us ed at each restart. To turn off DHCP use t he software GBL_Conf.exe or use the configuration via the web interfac e.

To check the network settings with GBL_Conf.exe, start the program and choose "All Devices" in the "Search" menu. From the list s elec t the appropriate device. The lower part of the left half of the window now shows the current network s ettings of the device. If the IP address i s dis play ed with the default s et t ings (192.168.0.2), either no DHCP server is present on the network, or there could be no free IP address ass i gned to it.

3.1 Power Ports

Choose Power Port to configure: This field is us ed to s elec t t he power ports to be configured.

Label: Y ou c an ass i gn a name up to 15 characters for each of the power ports. Using the name, an identificati on of the the device connected to t he port can be facil it at ed.

Connect twinport: This option combines t wo relays of the same number of Bank A and Bank B. E. g. A2 and B2. By t his c onnecti on a port always adopts the status of the connected port, so t hat both ports always have t he s ame s witching state.

23

Configuration

Start-up Monit ori ng

It is important, that if necessary t he condition of the power ports c an be restored after a power failure. Therefo re each port can be configured with Initialization st at us t o a s peci fic start-up state. This s tart-up sequence can be carried out delayed by the parameter Initializ ati on Delay. There is in any case a minimum one-second delay between switc hing of ports.

Initialization st at us (colds t art): This is t he port st at e (on, off, remember last state) the port should be set when the device is turned on. The sett i ng "remember last state" s aves the last manually set state of the power port in the EEP ROM.

Initialization st at us (bank repower): Had a bank not enough voltage, and is now adequately supplied again, the option "apply initialization st at us " l eads t o a repetition of the st art-up sequence for this bank. Is " remain in current state" selected, t he port st at e that is shown on display and web page is implemented.

Initialization delay: Here can be confi gured how long the port should wait to swit ch to its defined state after the device is t urned on. The delay may las t up to 8191 seconds. This corresponds t o a period of approx. t wo hours and 20 minutes. A value of zero means that the initi aliz at ion is off.

3.1.1

Repower delay: When this feature is enabled (value greater than 0), the power port will switc h itself on again a specified time after it has been disabled. Unlike the "Reset" button this function applies to all s witch actions, including SNMP, or an optional serial interface.

Reset Duration: When the "Reset" butt on is t riggered, the device turns the power port off, waits for the tim e entered here (in seconds) and turns t he power port on.

Ignore Powerloss on Bank x: The power ports of bank x are not automatically s wit c hed off when a voltage failure is detect ed, they keep their actual state.

This can lead to an increased total current c onsumpti on when the voltage is comi ng back, since the act i vated connected devic es are simult aneously turned on again.

Activat ion of this option makes sense, if the input volt age of the device deviates strongly from the si nusoidal shape. The internal signal evaluation might then erroneously ass ume a voltage drop, because the zero-cross i ng characterist i c t ypical for sinusoidal voltage curves is absent. One possible s ource of such non-sinusoidal voltage supply may be a simple UPS t hat produces rectangular output voltages.

Watchdog

The watchdog feature enables t o m onitor various remote devic es. Therefore either ICMP pings or TCP pings are sent t o t he devic e t o be monitored. If t hese pings are not answered within a certain time (both the time and the number of attempt s can be set), the port is reset. This allows e.g. t o automatically rest art not responding server or NAS systems. The mode IP mas t er-slave port allows you to switc h a port depending on the availability of a remote device.

When a watchdog is acti vated it presents various information in the Control Panel. The information is c olor-coded.

·

Green text : The watchdog is act ive and regularly receives ping replies.

·

Orange text : The watc hdog is c urrently enabled, and waits for the first P i ng response.
