In explosive environments the electrical installation must be performed according to ČSN EN 60079-14 (Electrical instalation in hazardours areas).

1. Assembly of the controller

   • a) Pull the handle on the right side of the controller to unlock and lift the cover
   • b) Drill the required amount of holes for bushings into the indents of the top and bottom part of the case
   • c) Anchor the controller on a flat surface using four 6mm fasteners
   • d) Connect the wiring
   • e) Close the cover of the case and lock the controller by using the handle

2. Connecting a transmitter via current loop
   Connect one transmitter on each channel of the controller:

3. Connecting a transmitter via RS485
   It is possible to connect up to 16 transmitters on each controller input, depending on their electrical distance from the controller.
   Wiring installation for RS485
   Wiring must be done using bus topology and according to the RS485 principles.
   Wiring must be done using bus topology and according to the RS485 principles.
   Maximum number of connected transmitters per controler channel is 32 (may be less depending on the configuration of the controller), while the total length of the connecting cable (electrical distance between the controller and the last transmitter) should not exceed 1200 meters. The maximal amount of transmitters connected to the bus and the type of cable used, according to the distance from the controller, is provided in the manuals of each transmitter.
   According to the RS485 specifications, the last device on the bus must be ending with a terminating resistor 120R. Plug a jumper on the JP2 connector of the last device on the bus to include the 120R terminating resistor. In the default configuaration the jumper connector is not plugged

4. Connecting the temperature sensor, flooding sensor and lay-off button of the beeper

5. Connecting the visual and acoustic alarms and the emergency valve

6. Selecting the supply voltage and the maximum current load

Supply voltage 230V AC
The highest current load of the controller is 1,4A. This current serves to power the connected transmitters and the visual and acoustic alarms, which are connected to the terminal blocks „LIGHT_SIG“ and „SOUND_SIG“.
Example: There are 4 transmitters connected to the controller with a consuption of 60 mA each. The remaining 1,16 A (I=1400-4×60) are used to supply the visual and acoustic alarms.

Supply voltage 24V DC
The consuption of the controler’s electronics is 300mA. Maximal current on terminal blocks „+24V IN/OUT“ is 10A. Maximal current load on each output on terminal blocks „LIGHT_SIG“ and „SOUND_SIG“ is 4A.
Example: There are 4 transmitters connected to the controller with a consuption of 60 mA each. The controller has a consuption of 300mA. The remaining 7,46 A (I=8000-300-4×60) are used to supply the visual and acoustic alarms.
Information on the constuption of each transmitters and components of the visual and acoustic alarms is given in the respective manuals.
Warning: never connect the supply voltage 24V and 230V simultaneously

Output relay

Each relay can by default be configured to activate on any number and any combination of events:

• Transmitter: 4 levels of gas leek alarms, PEL, STEL, transmitters malfunction
• Controller: 2 levels of temperature, flooding, controller malfunction, 2 levels of exceeded temperature, flooding indication
• Relays can after activations be configured for the following output functions: normally closed, normally open, cycling of open/close, automatic deativation of deactivatable outputs after a certain time or after pressing a button.
• Specific configurations of the relays are given in the configuration protocol provided to the controller

Regulating the supply voltage

• By means of trimru we can regulate the output voltage of the source in the range of 22-26V.
• If the sensors are connected at a great distance, it may be necessary to increase the supply voltage for proper function.

Controls

The control panel is equipped with a segmented LCD display and can be controlled using the LEFT, RIGHT and ENTER buttons.
In Basic mode the controller displays the concentration and the states of the configured channels. Digital channels (transmitters connected via RS485) are numbered 1 to 32, and analog channels (connected via current loop) are in the range of 41 to 48. The controller sequentially switches between the configured channels (basic interval 3s). For a longer display of a specific channel, briefly press ENTER (the channel remains displayed for 30s). The ENTER button also serves as a confirmation key for switching-off of the off-switchable outputs of the controller. The respective output remains in the defaul state for as long as there is no fading of the event that triggered it (concentration drop, disappearance of the error code).

Launch of the controller
After turning on the power supply, the whole LCD Display lights up and loads the highest meassured concentration, which remains on the display for cca 3s. After that the controller goes into preheating mode. The main LCD displays a countdown to the end of preheating and the secondary segments display the inscription „HEATING“.

Basic status/alarms
The controller displays the concentration on 4 main segments. To it’s right, units and the detected gas are being displayed. The 8 auxiliary segments display the location or an evnetual sensor malfunction. If the displayed channel is digital
(1 to 32), the adress of the connected sensor is also displayed. Connected analog transmitters have a range of 41 to 48. The controller sequentially switches the configured channels in a 3s interval. If we want to select a transmitter manually, we can do so with the buttons LEFT and RIGHT.
The status of the sensor bundled with an output relais (alarms, time-weigted avarages, statuses of temperature sensors and floodings, malfunctions) is displayed in the right part of the LCD.
In case of an increased concentration, the LED ALARM starts shining and the controller switches to the channel, which meansured this concentration. After 30s the channels will again be sequentially switched.
The latch function – catalytic and semiconducter sensors can, when exceeding the measuring range, indicate a lower measured value than it really is. If the measured concentration of these sensors exceed 100% of the lower explosion level, the latch will activate. Even after a drop of the measured concentration, the transmitter will still be in it’s highest alarm level. The detection area must be physically checked by an independent transmitter and after that the controller can be unblocked by pressing the ENTER button.
The ENTER button also serves as a confirmation button for the acoustic alarm.

Malfunction
If a malfunction should occur, the LCD displays the measured values, an error code and also a key symbol . The meaning of individual error codes can be found in the attachments.

Monitoring the calibraton periods
After 12 months since the last calibration (Max. calibration interval) an inscription starts flashing on the LCD display. The connected transmitters must be calibrated immediately.
Reading the record of measured concentrations and alarms
The controller periodically after 60s stores the current detected concentration into it’s internal memory. The internal memory retains data from the last 49 000 measurements (cca 34 days). In order to read this information, the program DegaConfig is required. Refer to the DegaConfig program instruction
Indication of past alarms
The controller is equipped with an indication of alarms that have already faded. If such an alarm occurred, the icon is displayed. To view these alarms, enter the menu HIST  HILA, where the date and time since the highest measured alarm since reseting HIST  _RST is displayed for each transmitter. After viewing the history it’s possible to reset the counter throught HIST  _RST and the icon disappears.
Automatic adjustment of the 0 point
The connected digital transmitters have an inner diagnostic, which detects whether or not the 0 point is in disbalance. If so, an automatic adjustment will take place and the controller indicates this with the icon .

Menu
Enter the menu by pressing the ENTER button and hold it for cca 5s. The main segments of the LCD display the menu functions. Use the arrows to move from one entry to another and press ENTER for selecting an entry. The last entry is always EXIT, which returns you to a higher menu level. The menu stucture is as follows:

History Menu HIST

This menu displays the highest measured concentrations in a selected time interval for each channel. There is a total of 8 intervals: – the last 1h (HI1H), 8h (HI8H), 12h (HI12H), 24h (HI24), 2 days (HI2D), 7 days, the entire memory (cca 34 days) and the interval since the last reset of „_RST“. Selecting an entry will perform a custom search in the memory for the selected channel. If during the whole interval the concentration hasn’t changed and remained on the minimal value, „9999“ will be displayed instead of the date and time. Switch between the channel by using the arrows and use ENTER to return back to selecting a time interval.
The entry _RST serves for setting the time interval for the user alarm. If since the last change of the entry _RST an alarm occurred at one of the transmitters, the basic status of the controller displays the segment „H“. At the entry, the date and time since evaluation of „HILA“ is displayed. Pressing ENTER on this entry sets the interval to the current date and time a the segment H disappears from the basic status. Press ENTER again to return the the history menu.
Note.: In case of equipping a larger quantity of transmitters, the loading of the history may take a few seconds.

Information menu INFO

The entries TMP1 and TMP2 change the temperature value of the external sensor at which an alarm occurs. Pressing LEFT decreases the temperature and pressing RIGHT increases the temperature. Press ENTER to confirm the change. Attention, the temperature alarm value changes immediately after pressing LEFT or RIGHT. If the immediate temperature value exceeds the alarm value, it will change the output state.
The entries ALM1 to ALM4 are used to set the alarm of the transmitters. Press ENTER to browse the alarms by using LEFT and RIGHT. Each channel shows the size of the alarm and the segment 1-4 shines, based on the selected alarm. Press ENTER again to move to the edit mode. The segment 1-4 blinks and we can set the value by using LEFT and RIGHT. Pressing ENTER again will end the edit mode. Attention, analog channel value changes are immediate and so are the output changes. The changes are saved after pressing ENTER.
The entry CALI serves for calibration of the digital transmitters. LEFT and RIGHT changes the displayed channel and ENTER selects the channel (displayed ). Moving to the entry NEXT and pressing ENTER goes to zero-calibration of the selected transmitters. This mode displays a minimal AD conversion value on the main segment. The secondary segments display the maximal value. The oxygen detector is an exception, which always detects a 0 value in the zero-mode. By using LEFT and RIGHT it’s possible to check the detected value of every selected transmitter and eventually wait for it to drop. Press NEXT to move to the calibration range mode. Inletting a calibration gas to the transmitter will start a concentration measuring of the calibration gas. The highest value of the AD conversion is displayed on the main display and the lowest value is displayed on the secondary segments. If we are satisfied with the values, we can move on to the next part by clicking NEXT, which will bring us to the settings of the calibration interval. This can be changed with LEFT and RIGHT and using ENTER will confirm the selection. In the final part of this whole process select either YES for saving the values into the transmitters, or no for finishing the calibration without saving the values.

Controller testing menu TEST

The entry RELE is used for direct setting of the controller outputs. Entering this entry saves the current state of the outputs, which are later modified by the user. The controller outputs (RE1 to RE10, LIGH, SOUN, _HV) can be browsed with LEFT and RIGHT and pressing ENTER will switch the output state. The outputs will remain in these settings for as long until we don’t press ENTER on the last EXIT entry. That will restore the output state, which existed before the user change.
The entry TRAN is similar to the entry RELE, except for the fact that the user sets the concentrations on the given channel. Use LEFT and RIGHT to select a channel and then press ENTER to enter the edit mode. Here we can use the arrows to change the concentration ranging from minimal to maximal value of the configured transmitter. The controller reacts to this set concentration as if it was directly measured, which leads to occurring alarms and switching outputs.
The entry _RST resets the controller.

Service Menu SERV
The entry SERV ALL SENS makes the controler go into service mode. The communication with transmitter is stopped and the outputs are set in the last known state. Use LEFT and RIGHT to set the servise interval in a range of 1 to 24 hours. Press ENTER to start it’s own regime.
The main segments display a countdown of the set interval in seconds and the malfunction segments (key symbol) blinks. After the countdown finishes, the controller returns to the detection mode. This regime can be interrupted anytime by pressing ENTER.
The entry SERV SEL SENS causes a blockage of any transmitter until the next restart of the controller. Use LEFT and RIGHT to select a transmitter and ENTER to block/unblock. Blocked transmitters are indicated with an inscription DIS on the main segments.

Maintenance

Operation/Maintenance
In case of contamination the surface can be cleaned with a slightly moistened cloth. The connected transmitters require performing of regular checks and calibrations, which can be done in two ways:

• a) 1x every six months carry out a „calibration“ and functional control – adjust the sesitivity of the sensor using calibration gas and check the functionality of the system. The exact interval depends on the purity of the environment, required accuracy and the occurrance of disturbing gases in the atmoshpere.
• b) 1x every twelve months carry out a „calibration“ – adjust the sesitivity of the sensor using calibration gas and check the functionality of the system. The exact interval depends on the purity of the environment, required accuracy and the occurrance of disturbing gases in the atmoshpere. Also carry out a „functional control” 1 x every three months – checking the function of the entire detection system using a test gas, which does not exceed the range of the sensor. We recommend using gas intended for laboratory use.
  For the „functional control“ do not use means for testing fire alarm detectors!

Perform calibration only at certified service centers with a valid certificate of competence or the manufacturer. For the Czech Republic only DEGA CZ s.r.o.

Replacement of the battery

The battery lifetime in the controller is approximately 5 years. After this time some functions of the controller may not work properly. Remove the battery from the holder and replace it with one of the recommended types. Replacing the battery in the controller, which is not connected to the power supply, will erase the internal clock.
