General Notes on the Structure of this Manual
This documentation describes the function, operation, commissioning and maintenance of the EnCal 3000 Controller.
This controller is part of the EnCal 3000 Gas Quality Measurement System, which also consists of the EnCal 3000 Gas
Chromatograph (GC). When mentioned within this documentation, “EnCal 3000” or “controller” always refers to the
EnCal 3000 Controller.
Tip: Chapter 4 provides brief instructions on how to accomplish regular tasks during routine tests in the station. It is
intended for the impatient reader who does not want to read the entire manual first just to accept an error. It is,
however, necessary to read the entire manual to comprehend the device’s mode of operation.
Three manuals describe the EnCal 3000 gas quality measuring system:
The manual on hand deals with the controller. The other two manuals deal with the hardware and the PC
parameterization software of the gas chromatograph.
The entire Technical Documentation must always be at hand in the station.
Safety and Warning Notes
Attention! The following safety and warning notes must be observed at any rate:
The EnCal 3000 Controller must neither be stored at temperatures below -20°C nor above +50°C.
A temperature between 0°C und +40°C must be guaranteed during operation.
The EnCal 3000 Controller must be installed outside hazardous area 2 as it is not an explosion-proof device.
The EnCal 3000 Gas Chromatograph, however, is explosion-proof.
The EnCal 3000 Controller can be equipped with hardware modules that are approved as associated
electrical apparatus of category ib according to DIN EN 50020 with intrinsically safe circuits (EXMFE5 /
EXDE6 input boards). It is therefore suitable for being connected to sensors, signal transmitters and pulsers
located in hazardous areas (e.g. zone 1). It is not permitted to connect intrinsically safe and non-intrinsically
safe circuits to these modules together.
The power supply of the EnCal 3000 Controller is 24 V DC and must be secured externally by 1 A.
Connect the earthing to PE of the power supply socket for equipotential bonding.
Observe the regulations of the relevant standards, in particular the regulations of DIN EN 50014, DIN EN
50020 and DIN EN 50029.
Observe the limit values stated in the respective certificates of conformity of the boards to be connected.
(Please refer to the annex for the certificates of conformity.)
Warning: This is a Class A device that may cause interferences in living areas; you may be asked for
appropriate measures at your expense if the device is installed in such areas.
