Company Products Technical support Press center Site Map Compressor control unit BUK326.1 Key Features 16- digit matrix vacuum luminescent display continuous measurement and display of temperature and pressure "Soft" start of the compressor, reducing starting currents protection against exceeding the permissible pressure and temperature automatic stop and start of the compressor, reducing energy consumption temperature sensor included Designed for automatic control of a compressor unit. Provides measurement and display on a digital indicator of the current pressure in the working line and the temperature of the screw block of the compressor. The unit performs a stepwise start of the compressor engine (acceleration according to the "star" scheme followed by switching to the "triangle" scheme), automatic maintenance of pressure within the specified limits by switching the compressor to idle or operating modes, shutdown of the compressor in case of emergency pressure and temperature values, and drainage of condensate at specified intervals. The unit also calculates the operating time of the compressor and informs about the need for maintenance (replacement of filters and oil) after the specified operating time. The unit provides an auto-stop function for prolonged operation in idle mode (with automatic start when the pressure drops) and an auto-start function when the power supply is restored. The unit has three outputs for controlling electromagnetic starters to start the engine and two outputs for controlling low-voltage idle and condensate drain valves. To set the required parameters of operation and maintenance of the compressor, the block provides menus protected from unauthorized access by a password. For additional control convenience, warning LED indicators are provided on the front panel of the unit. The compressor is controlled and parameters are entered using the clock buttons on the front panel. The unit is made in a built-in aluminum alloy housing and has a dust-splash protection design. The unit is connected using screw connectors on the back of the case. The kit includes a temperature sensor and connecting harnesses.
