Design
The GD product range is designed in a very flexible
way with a mother PCB (Print Circuit Board) and an
interchangeable precalibrated sensor PCB.
The mother PCB is the same for all GD models
independent of the refrigerant or sensor
technology. On the mother PCB individual settings
(Alarm levels, delays e.t.c) can be set to meet local
legislation or application requirements.

The sensor PCB is always precalibrated and dedicated
to the actual refrigerant and ppm range. Danfoss has in
advance selected the most appropriate sensor making
it easy to optain safe detection and avoid false alarms
from other gases present.
Because of the interchangeable precalibrated
sensor PCB, it is very easy to replace the sensor
when service or a calibration procedure is required
(see the below drawings).

Sensor technology
Danfoss has, depending on actual ppm range and
refrigerant, selected the most appropriate sensor for
the target refrigerant gas. When the refrigerant and
actual ppm range has been decided, the Danfoss
GD product range makes it easy to pick out the right
product.
Electrochemical Sensors - EC
EC sensors are used mainly for toxic gases and are
suitable for ammonia but not for the other refrigerants.
They are very accurate and tend to be used principally
for toxic gases which cannot be otherwise detected or
where high levels of accuracy are needed.
Catalytic - CT
CT sensors have been mainly used for combustible
gases including ammonia. CT are relatively low-cost,
well established and understood and they have a
good life span, up to 5 years. They can be subject to
poisoning in certain applications but not generally in
refrigeration and are more effective at gas levels of
above 2,000 ppm.
Below is a brief introduction to the GD sensor types.
For further information - please contact Danfoss.
Semi-conductor – SC
SC sensors can be used for a wide range of gases
including combustible, toxic and refrigerant gases.
The SC sensors are low-cost, long life, sensitive, stable,
resistant to poisoning and can be used to detect a
large range of gases including all the CFC, HCFC, HFC
refrigerants, ammonia and hydrocarbons.
However, they are not selective and are not suited to
detecting a single gas in a mixture or for use where
high concentrations of interfering gases are likely to be
present.
Calibration / test methods
Infrared - IR
IR sensors are very specific and is very precise for
detection of CO2.
The calibration procedure consist of:
• Annual checks by qualified bump test
• Calibration by replacement of the sensor PCB with a
Danfoss pre-calibrated certified sensor PCB
Annual Test
To comply with the requirements of EN378 and the F GAS regulation sensors must be tested annually.
However local regulations may specify the nature and frequency of this test. If not the Danfoss
recommended bump test procedure should be followed. Contact Danfoss for details.
For increased accuracy the unit must be calibrated at the temperature of operation.
After exposure to a substantial gas leak, sensor should be checked and replaced if necessary.
Check local regulations on calibration or testing requirements.
Method I
Calibration / test by means of
replacing Sensor PCB
This method requires that Danfoss offers factory
calibrated PCB sensor boards with calibration certificate
and traceability codes. Additionally an electrically
simulation is required to verify the output signals and
alarm settings.
The PCB sensor board, which is the essential measuring
element of the gas detector, is produced, calibrated,
tested and certified by Danfoss.
After the main PCB of the gas detector has been tested
with the GD tester, the new calibrated Sensor PCB can
be installed.
Test and calibration of GD Main
Board by the use of GD tester
Danfoss recommends that the calibration / test
procedure is done by means of replacing the Sensor
PCB, because:
• No need to purchase calibration gases in several
different concentrations
• Simpler and quicker than gas calibration
• Danfoss guarantees the correct calibration and
functioning of the new sensor PCB, which is supplied
with a calibration certificate.
• No problems with sensor deterioration or end-of-life
• Price competitive, compared to the gas calibration
carried out on site.

Bump test
A Bump Test consists of exposing the sensor to a gas. The objective is to establish if the sensor is reacting to the
gas and all the sensor outputs are working correctly. A qualified bump test is a test carried out using ampoules or
similar of known concentration.

Functions - all models
All GD models shown above have the same basic
functions. All settings are done by means of jumper
settings on the mother PCB.
See the section “Mother PCB” for more details.
For detailed information on how to adjust Alarm
setting - please see the instruction PI.S00.A.
Alarm
All GD models can detect 2 alarm levels and give
alarm via 2 volt free contacts. When an alarm has been
detected a yellow LED (Low Level Alarm) or a red LED
(High Level Alarm) will go ON. All GD sensors have
been preset by the factory, to realistic Low/High values
related to the actual ppm range of the GD model. The
actual Low and High Alarm ppm values can be read on
the external GD label.
The 2 volt free contacts can be set individually to either
Normally Open (NO) or Normally Closed (NC).
All GD models are factory set to NO
NO/NC can not be used as fail safe during power failure.
Normalization Period
With the option Auto reset selected, the release of the
Low or High Level Alarm is done automatically.
All GD models are factory set to Auto Reset.
The factory preset values can be adjusted, with a
voltmeter measuring a 0-5 V d.c output.
0 V corresponds to the min. ppm range (e.g. 0 ppm)
5 V corresponds to the max. ppm range (e.g. 1000)
Example:
If a setting of 350 ppm is required the voltage shall be
set to 1.75 V (35 % of 5 V)
Analog Output
All GD will continuously generate a linear analog
output, proportional to the gas concentration. The
signal is available as 4-20 mA, 0-10 V and 0-5 V.
All are available at the same time (see next page).
LCD display
The model with the LCD display will continuously
display the actual present ppm level in the room and
the Alarm messages.
Upper Line:
Actual present ppm level (e.g: “580 ppm”).
Both Low and High Level Alarm can be delayed
individually before the 2 volt free contacts are
activated. This is useful when cross interference from
other gasses may occur. The delayed response time can
be set to 0, 1, 5 or 10 minutes.
All GD models are factory set to 0 minutes.
When the GD sensors have detected a Low or High
Level Alarm an option for having these alarms with
Manual reset or Auto Reset is possible. With the option
Manual reset selected, a push button on the mother
PCB must be activated to release the Low or High Level
Alarm.
Lower Line:
Alarm status.
4 text messages are possible - only one at a time:
“No Alarm”
Neither Low Level Alarm nor High Level Alarm active.
“Lo Alarm on”
Low Level Alarm active.
“Lo,Hi Alarm on”
Both Low Level Alarm and High Level Alarm active.
“Hi Alarm on”
High Level Alarm active.
Once the GD is powered up it takes some time to
normalize. When GD is powered up it will give a
higher analog output (4-20 mA/0-10 V/0-5 V 1)) in the
beginning and after some time it goes back
to the actual concentration (in clean air and no leaks,
the analog output will go back to:
~ 0 V/4 mA / ( ~ 0 ppm)) 2)
1
Times below are only intended as a guide.
They may vary due to temperature, humidity,
cleanliness of the air, storage time 3) etc.
Model
EC Sensors are 2 min (all models)
SC Sensors are 60 minutes (all models)
CT Sensors are 60 minutes (all models)
IR Sensors are 2 minutes (all models)
)
Always use the voltage 0-10 V to check the output for
normalization check
)
GDC IR goes back to about 400 ppm as this is the normal
level in air. (~4.6 mA/~0.4 V/ 0.2 V)
2
)
If the GD has been in long-term storage or has been turned
off for a long period, normalisation would be much
slower. However within 1-2 hours the GD should have
dropped below the low alarm level and be operational.
The progress can be monitored exactly on the 0-10V
output. When the output settles around zero (400 ppm
in the case of IR CO2 sensors) the GD is normalised. In
exceptional circumstances particularly with SC and CT
sensors the process can take up to 30 hours.
3
For SC Sensors, it must be calibrated at temperature of
operation.

GD connected to
Danfoss monitoring
Danfoss offers the possibility of connecting every GD,
independent of model, via the built-in RS 485 Bus
communication, directly to the Danfoss monitoring
unit.
Up to 31 GD sensors can be connected via a twocore screened communication cable (see the below
drawing).
Every GD sensor needs a unique address number which
must be selected. The address of GD is set by S2 and
S3. By setting S2 and S3 between 0 and F, the GD will be
assigned an address. See next page.
A conversion chart between channel number of the
Danfoss monitoring system and the hexadecimal
address of the GD is attached. Power must be removed
when setting the addresses on the GD sensor.
If more than 31 units are needed, a GD Repeater
(amplifier) must be installed (see Accessories).
Contact Danfoss for further information.
