Digital Gas Controller System CGD-05
1 Application Intended for Use
CGD-05, Gas Controller is used for monitoring and warning of toxic and combustible gases and vapours in the
ambient air.The CGD-05 Gas Controller fulfils the requirements according to VDI 2053 (January 04),
ÖNORM and NVN 2443 for the stationary monitoring of carbon monoxide (CO), nitrogen dioxide (NO2)
and combustible gases in underground garages, tunnels, go-cart race courses etc. The CGD-05 Gas
Controller also meets the requirements according to EN 378, VBG 20 and the guidelines "Safety
requirements for ammonia refrigeration systems". The Gas Controller can be used as well for monitoring
lots of other gases.
The intended sites are all areas being directly connected to the public low voltage supply, e.g. residential,
commercial and industrial ranges as well as small enterprises (according to EN55 02). The Gas Controller
may only be used in ambient conditions as specified in the Technical Data.
The Gas Controller CGD-05 must not be used in potentially explosive atmospheres.
2 Description
The Gas Controller is a measuring and warning controller for the continuous monitoring of different toxic or
combustible gases and vapours as well as of Freons. The CG-05 is suitable for the connection of up to 98
digital transmitters via the 2-wire bus. In the 48/48 MP addressing mode you can connect 48 transmitters with 4
to 20 mA input for the connection of an analog transmitter. There are 4 analog inputs available at each PE-05
module in addition. The controller can be employed as analog, as analog/digital or as digital controller. The
total number of connected transmitters, however, may not exceed 96 respectively 98 transmitters.
Up to five free programmable alarm thresholds are available for each transmitter. For transmitting the alarms
there are up to 30 relays with potential-free change-over contact.
Comfortable and easy operation of the Gas Controller is done via the logical menu structure. A number of
integrated parameters enables the realisation of various requirements in the gas measuring technique.
Configuration is menu-driven via the keypad. For fast and easy configuration, you can use the configuration
software CGD-EasyConf.
Prior to commissioning please consider the guidelines for wiring and commissioning of the hardware.
2.1 Normal Mode
In normal mode, the gas concentrations of the active transmitters are continuously polled and displayed at the
LCD display in a scrolling way. The controller also monitors the communication to all active transmitters and
modules.
2.2 Alarm Mode
If the gas concentration reaches the programmed alarm threshold, the alarm is started, the assigned alarm
relay activated and the alarm LED (orange for alarm1, red for alarm 2 + n) starts to flash. The set alarm can be
read from the menu Alarm Status. When the gas concentration falls below the alarm threshold plus hysteresis,
the alarm is automatically reset. In latching mode, the alarm has to be reset manually in the menu Relay Status
or via a digital input.
2.3 Fault Mode
If the controller detects an incorrect communication at an active transmitter or module, or if a signal is outside
the admissible range (< 3 mA - > 22 mA), the assigned fault relay is set and the error LED starts to flash. The
error is displayed in the menu Error Status in clear text. After removal of the cause, the error message has to
be acknowledged manually in the menu Error Status.

3.3 Code Levels
According to the regulations of all national and international standards for gas warning systems, all inputs and
changes are protected by a four-digit numeric code (= password) against unauthorised intervention. All menu
windows are visible without entering a code.
The release of a code level is cancelled if no button is pushed within 15 minutes.
The code levels are classified in order of priority: Priority 1 has top priority.
Priority 1: (fixed value – not changeable)
Code level priority 1 is intended for the service technician of the installer to change parameters and set-points.
All settings can be edited with this password.
Priority 2: (fixed value – not changeable)
With code level 2, it is possible to lock/ unlock transmitters temporarily.
This password is only given to the end user by the installer in problem situations.
Priority 3: (settable)
It is only intended to update the maintenance date, as well as to turn on and off the service mode.
Normally the code is only known by the service technician.
It can be changed individually via priority 1.
Priority 4: (password 1234) (fixed value – not changeable)
Code level priority 4 allows the operator:
- to acknowledge faults
- to manually operate the alarm relays
- to set date and time
- to configure the data logger.

4.1 Fault Management
The integrated fault management records the first 20 faults with date and time stamps in the menu „System
Errors“. Additionally a record of the faults occurs in the “Error memory”, which can only be read and cancelled
by the service technician.
An actual fault activates the fault indication relay which is defined in the system parameter “Fault relay” after an
internal fault delay time of 2 minutes. The yellow LED (Fault) starts to flash and the fault is displayed in plain
text with date and time in the starting menu.
In case of the fault of a connected transmitter the alarms defined in the menu “MP Parameter” are activated in
addition.
4.1.1 Acknowledge a Fault
Attention:
According to the directives of the gas measuring technique, accumulated errors aren’t allowed to be
acknowledged automatically. Therefore, acknowledgment of a fault is only possible after having removed the
cause!
Select menu “System Errors”
Example: Communication error MP01.1
Acknowledge the fault message?
Fault message acknowledged.
or
Fault acknowledged Cause not eliminated
Reset not possible
4.1.2 Error Memory
The menu „Error Memory“ in the main menu “System Error” can only be opened via the code level priority 1.
In the error memory, the 20 first faults already acknowledged in the menu “System Error” are listed for the
service technician in a power failure safe way.
This memory should always be emptied during maintenance.
The deletion of each individual message is effected in the same way as the reset of a fault.

Direction of the alarm release
In the gas measuring technique, most of the gases are monitored for their increasing concentration. For
example oxygen, however, is monitored for its falling concentration. In this menu there is the definition how
many of the 5 alarm thresholds monitor a falling concentration.
4.6.4 Measuring Range Definition
The measuring range can be adapted to the working range of the connected gas transmitter within 1 to 9999.
This also influences the display of the measured values, the alarm threshold as well as the hysteresis. Two
decimal places are displayed for measuring ranges <= 10, one decimal place for measuring ranges > 10 and
<= 100 and no decimal place for measuring ranges > 100.
4.6.5 MP Signal Definition
Gas transmitter using electro-chemical or catalytic beat gas sensors normally produce a linear signal,
proportional to the gas concentration.
Semiconductor gas sensors produce a non-linear (exponential) signal due to the measuring function. This
signal leads again to a non-linear 4 to 20 mA signal of the gas transmitter.
The Gas Controller CG-05 is prepared for both types of gas transmitters. The classification of signals is defined
in this menu.

4.6.6 Threshold/ Hysteresis
For each measuring point five alarm thresholds are available for free definition. If the gas concentration is
higher than the set alarm threshold, the associated alarm is activated. If the gas concentration falls below the
alarm threshold inclusive hysteresis the alarm is again reset. In the mode “Alarm at falling” the corresponding
alarm is set in case of falling below the set alarm threshold. The display depends on the set measuring range:
see 4.6.4. Unused alarm thresholds have to be defined at measuring range end point, in order to avoid false
alarms.

4.6.7 Delay for Alarm ON and/or OFF
Definition of delay time for alarm ON and/or alarm OFF. The delay applies to all alarms of an MP, not with
average value overlay, see 4.8.6.

end of the fixed time (sec.). 0 sec. = No delay

4.7 Menu Data Logger
This function is available from software version 9.02.
But only if the CG-05 controller is equipped with a mini USB interface incl. USB special cable at the bottom side
of the module. This option can’t be retrofit.
Connect an USB device at the USB cable to use the data logger function.
This USB device may be for example an USB stick version 2.0 (not all types have been tested).
In this menu, the parameters for the long-term recording of the USB device are set.
