Introduction VaporTEK Valve Adapter Board (Optional)16Jumper J1/J2 defines the function on P4A / P4B input. A placement on position 1-2 sets the P4 input as pulsetrain input. With a placement on position 2-3 the P4 input is used as a Diesel - disable input. In this mode all pulsetrain inputs will be disabled if the voltage on P4 – Input is higher than 2.5V DC.VaporTEK Valve Adapter Board (Optional)The VaporTEK-3 – Controller Board, Rev. C, provides a dedicated output to the VaporTEK Valve Adapter board . Apulse wide modulated (PWM) signal is used to control the valve power for each side separately. An on-boardintegrated current regulator is stabilizing the valve current against temperature drift on the valve solenoid head.An equalizer setup function provided by the FB1 – Service terminal (with software version 6.9 and above) allowsthe service technician to calibrate the valve power in dual transaction mode. This setup can also be done using alaptop along with the USB Service/ Flash – Adapter. Two setup points for each valve will be used to calibrate thevalve curve. During a single side transaction the EPV’s are controlled in ON/OFF - Mode.Washers with 3mm orifice used to avoid ghost transaction on the Vaporix Monitoring can be omitted in thisconfiguration.
