  • Page 10: Electrical Connections

    TecJet 110 Fuel Metering System Manual 26185 The inlet and outlet piping of the TecJet 110 must be in accordance with ANSI/ISA-S75.02 to ensure the flow metering accuracy specified elsewhere in this manual. However, an inlet piping length as short as 6 diameters and an outlet piping length as short as 2 diameters can typically be used with a negligible loss in valve metering accuracy.

  • Page 12: Earth Ground

    The keyswitch is not active in all TecJet configurations. The keyswitch is used to switch the TecJet 110 in and out of a low power state (less than 200 mA input current). A high signal (connected to supply [+]) will allow the valve to operate in a normal mode, and a low signal (connected to supply [–] or open connection)

  • Page 13: Pwm Input

    TecJet 110 is used on an engine. If one TecJet 110 valve is replaced with another, the new valve will read the correct ID number from the engine harness connector. See the table below for the code definition.

  • Page 14: Can Termination

    According to the CAN specification, every CANbus must be terminated at both ends of the bus. If a TecJet 110 valve is connected to the far end of the bus, this termination resistor can be used. If termination is needed, connect a link between pins P and Q.

  • Page 15: Can Shield

    E = Status Output J = Discrete/RS232 Common The status output indicates whether the TecJet 110 valve is operating correctly. It will be "on" when the valve is operating normally and "off" when any warnings or errors are active. The Status Output is a high-side switch: it will be actively driven to Battery (+) when "on"...

  • Page 18: Position Limiter

    Manual 26185 Position Limiter After the TecJet 110 is powered up and receives a flow command, the valve remains in a closed position until the delta-p sensor senses a non-zero valve delta-p. This non-zero delta-p is established when the fuel source is turned on.

  • Page 27: Position Hold Feature

    The TecJet 110, 50 Plus, and Precision Flow devices have a position hold feature for use in analyzing or troubleshooting engine system operation. This allows qualified operators to bypass the normal flow control function and specify a fixed valve position.

  • Page 28: General Specifications

    TecJet 110 Fuel Metering System Manual 26185 The Position Hold feature requires a valid flow command for position hold to function. The command is not used for positioning, but in order to control the position, the flow command must be valid. The position limiter function is also active so it may not be possible to achieve the desired position without increasing the flow demand.
