COM1 port. The pins designation is described in Figure 5.2. It is recommended to used CZAK-03 barrier to connect the power supply to the CMK-03. The CZAK-03 is manu- factured by COMMON S.A. (see Table 2.1 Additional Accessories).
WARNING! It is obligatory to connect correctly the intrinsically safe circuits of the device. It is not allowed to connect to the CMK-03 clamps any external devices with undefined pur- pose. For example: the connection between the output of external power supply (V+,GDN,A,B) with the ExtCPC output of the CPC-03 external converter may occurs permanent device damage and loss of intrinsically safe parameters.
The all cable glands are in EMC execution and are adjusted to connection of the cable shields in their entering place. In the CMK-03 there are two types of the cable glands: M12 and M16 — a ranges of the cable glands diameter are listed in the Table below.

5.5 Connection of the P1 and P2 pressure sensors The CMK-03 has maximum two built-in pressure converters (P1 and P2 in the Figure 5.10). The connection pipe of the converter has a threat M12x1,5 in the typical application. The available variants and the pressure ranges are listed in the Table 4.5.
Connection of the external CPC-03 pressure converter The CMK-03 allows for a reading and registration of the pressure values from two CPC-03 external, digital con- verters manufactured by COMMON S.A. (Table 2.1. Additional Accessories). The technical data of the CPC-03 converter are available in the operating instruction.
The connections between the converter port and converter clamps are presented in the Figure 5.14. Figure 5.14 The connections of the CPC-03 pressure sensor to the CMK-03 converter clamps . The clamps of the ExtCPC ports are doubled in the both terminal strips. This allows for easy, parallel connection for two cables to the electrical same ExtCPC port.

For the “K1=const” method there is no necessary to define the gas composition. The K1 coefficient is equal with the Z/Zb ratio. The conception of this method is to use the CMK-03 on a bio-gas station or others stations where the gas components exceed applicability ranges of the implemented calculating methods in the converter, and operating pressure does not exceed determinate value.
Bio gas configuration AGA8 or SGERG-88 ( The CMK-03 converter is a MID device. The algorithms such as approved according to the standard) have a limits of the incoming parameters value. This limits do not allow to define a value of the compressibility coefficient for gases and their mixtures which are out of range of the approved applicability.

COMMON S.A. OPERATING INSTRUCTION CMK-03 The unit MJ/m is default for Hs parameter in the converter. The Hs value conversion per unit kWh/m is follow- ing: 1 MJ/m = 3,6 * 1 kWh/m Important! The algorithms which calculate the value of Hs heat combustion, take into consider the T1 temperature (parameter) as a reference temperature of the combustion process.
User protective seals – Seal 3 The CMK-03 construction predicts the places dedicated for a user protective seals (see Figure 8.13). User is obli- gated to place the protective seals after device installation. They should be placed after control of the device me- chanical installation and electrical connection what should be done accordingly to this operating instruction and other safety rules.
