Product descriptions
1.1 Intended uses / Applications
The GLD Small series leakage detectors continuously monitor the indoor air for any refrigerant leaks. The devices can be used for refrig-
eration applications (cold rooms, freezer rooms, equipment rooms).
Always check the refrigerant type setting and the warning and alarm thresholds, as described later in this manual.
The GLD series detectors are available in the following congurations:
• GDSB - Built-in version
• GDSR - Remote version
They are calibrated to detect most refrigerants currently available on the market. The sensitive elements are constructed using semicon-
ductor (SC) technology or infrared (IR) technology.
The GLD series detectors can be used in stand-alone applications or connecte to Carel controllers or third-party devices. Communica
-
tion with Carel controllers uses an analogue output, or an RS485 Modbus® serial connection.
When a refrigerant leakage exceeding a certain concentration threshold is detected, an alarm or warning status is activated, depending
on the level of concentration set, and the GLD responds as follows:
• The combination of LEDs that are on changes;
• A dedicated internal relay (SPDT) is activated;
• The analogue output is controlled (in proportion to the detected concentration);
• The change in status is signalled via the RS485 Modbus® output and the RILEVA TE application.
Furthermore, the “RILEVA TE” app, available in both App Store and Play Store, can be used to access the device.
The GLD Small series detectors ensure compliance with refrigeration safety standards (EN 378) through visual and audible alarms to alert
personnel in the event of a refrigerant leakage.
WARNING: semiconductor sensors detect the gas they have been calibrated for, but are also sensitive to other types of gases, solvents,
alcohol, or substances containing ammonia, such as cleaning products, present in the environment. This, in certain areas and applica-
tions, can lead to false alarms when the substances described above are present. Nonetheless, although they do not only detect the
specic gas, they still give a reliable indication of the concentration of the gas they have been calibrated for.
WARNING: This device is neither certied nor approved for operation in oxygen-enriched atmospheres. Non-compliance can lead to
EXPLOSION.
WARNING: This device has not been designed to guarantee intrinsic safety when used in areas classied as hazardous (“Directive 2014/34/
EU ATEX” and “NFPA 70, Hazardous Location”). For operator safety, DO NOT use it in hazardous locations (classied as such).
GLD Small is available in ve main versions:
• Infrared version for CO
2
• Electrochemical version for ammonia
• Semiconductor version for R32 refrigerant gas blends
• Semiconductor version for HC refrigerant gases
• Semiconductor version for HFC/HFO refrigerant gases
