1. The complex provides:
- measurement of excess gas pressure at the input and output of the reduction unit and at the output of the control unit task pressure to pneumatic pressure regulators;
- control of the position of the cranes of each controlled reduction line;
- setting the status of each controlled reduction line (working, reserve disconnected or under repair);
- reception and transformation of information about the current volume flow of gas through the reduction node coming from the computer volume consumption of gas;
- reception of control commands of the complex and reduction lines coming at the initiative of the GRS operator from the control panel by the reduction node (hereinafter - the control panel) or from the UMG dispatch center (UMG Subdivision);
- automatic protection of consumers against inadmissible deviations of gas pressure at the outlet of the gas boiler by means of control according to the specified the algorithm of the taps of the reduction lines when the pressure at the output of the HRS reduction node deviates from the specified limits;
- pressure regulation and/or limitation of gas volumetric flow rate at the outlet of the HRS reduction unit by changing (by the HRS operator, by the UMG dispatcher) tasks to the pressure regulators installed on the reduction lines;
- storage in memory of a set of values of measured parameters and messages about events occurring in the technological the process of gas reduction, and about the actions of the GRS operator and the UMG dispatcher when managing the complex;
- issuance of warning and emergency signaling signals to the HRS operator;
- indication on the liquid crystal display (LCD) of the control panel of the current and set limit values of the measured pressure, the reasons for triggering the warning and emergency alarms, as well as the reasons for the malfunction of the complex;
- transfer on request of the "upper level" of the data generated by the complex, to the ACS of the GRS or to the SE of the UMG;
- turning on the sound and light alarm at the HRS and in the operator's house.
2. The maximum number of controlled and managed gas reduction lines . . . - 8.
3. Number of overpressure measurement channels . . . - 3.
The upper limit of measurements is set in the range . . . - from 100 to 10,000 kPa.
4. The limits of the reduced permissible error when measuring excessive gas pressure are ±0.10; ±0.15 or ±0.25% the upper limit of measurements.
5. The complex provides electric power for the control solenoids of the taps of the reduction lines with a DC voltage of 24±3 or 110±5 V.
6. Power supply of the complex:
- main: - from an alternating current network with a voltage from 160 to 250 V and a frequency of (50+1) Hz.
  - consumed power . . . . . . . . - 50 VA;
- reserve: - from a direct current power source (accumulator battery) with a nominal voltage of 24 V.
 - power consumption . . . . . . - 5 W.
When the 220 V electrical network is turned off, the complex continues to function fully for 24 hours. At the same time, it ensures the preservation of measurement information and the normal operation of the complex with the possibility of up to 30 permutations of cranes, with the consumption power of one faucet control solenoid up to 30 W.
7. The operation of the complex is allowed at an ambient air temperature of minus 40 to plus 60 °C.
8. The service life of the technical means of the complex is at least 10 years.
