MID 128 PID 45įMI 3 The wire between the engine control unit from the contact EB31 and the relay K48 closes to a constant plus, the relay K48 is faulty. Starting the engine in cold weather is difficult. The code is active only if the ignition lock key is in the preheating position (between the ignition on position and the engine start position)įMI 4 The wire between the engine control unit from the EB31 contact and the K48 relay is shorted to ground, the K48 preheating relay is defective. The air heater is permanently activated, as a result of overheating, the heating coil may be destroyed and parts of the coil may enter the intake manifold of the engine and the valve mechanism.įMI 5 An open circuit, a power supply fuse for the heating relay, a wire breakage between the engine control unit and the relay, a break in the power supply relay of the relay. Heating does not turn on, starting in cold weather is difficult. Max.FMI 3 The voltage on the contact of the engine EA6 EAU is higher than 65% of the battery voltage, short to positive, a broken power or ground wire, or a sensor fault on the fan. The fan rotates at maximum frequency, which causes high fuel consumption.įMI 8 The engine block has detected extra pulses in the fan speed signal, the wiring is damaged or the wires are poorly insulated, the sensor on the fan is faulty, the fan is faulty. The fan rotates at maximum frequency, which causes high fuel consumption. < 0,1% Rd/bar typical N 2 0,01% Rd/bar typical H 2 Optional Multi Gas / Multi Range functionality up to 10 bar abs Technical specifications Measurement / control systemįlow range (intermediate ranges available)Īccuracy (incl. The EL-FLOW ® Select design features optional Multi Gas / Multi Range functionality, providing (OEM-) customers with optimal flexibility and process efficiency. As an option, an on-board interface can be mounted to provide CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocols. In addition to the standard RS232 output the instruments also offer analog I/O. The main digital pc-board contains all of the general functions needed for measurement and control.
As a function of a setpoint value, the flow controller swiftly adjusts the desired flow rate.ĮL-FLOW ® Select series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The MFC consists of a thermal mass flow sensor, a precise control valve and a microprocessor based pc-board with signal and fieldbus conversion. Gas Mass Flow Controllers for low flow ratesīronkhorst ® model F-201CV Mass Flow Controllers (MFCs) are suited for accurate measurement and control of flow ranges between 0,16…8 ml n/min and 0,5…25 l n/min at operating pressures between vacuum and 64 bar.
