    Auxiliary I/O The three auxiliary inputs control the three auxiliary outputs (1 to 1, 2 to 2, and 3 to 3). These are configurable in the S numbers. Standby Mode Standby Mode will occur when the engine is not running and the controller has not seen any activity for 30 minutes.
  • Page 24 S-Number Description LOP @ LOW SPD: The EMS PRO Controller gives you two oil pressure shutdown points. For engines that develop very little oil pressure at an idle, you put a lower shutdown setting in this set point. The controller automatically changes the shutdown point between the Low Speed Shutdown point and the High Speed Shutdown point.
  • Page 25 S-Number Description CRANK TIME: Set this delay to the desired amount of time you want each engine cranking attempt to last. Consult your engine manual for recommended cranking and resting times (adjustable from 1 to 30 seconds). Factory set to 10. REST TIME: Set this delay to the desired amount of time you want each rest period between cranking attempts to last.
  • Page 26 S-Number Description THR FDBK DLY: This set point is used to adjust the amount of time the controller waits to sample the change made by the previous throttle pulse. If the system pressure, for example, takes a long time to change based on engine speed changes, this set point should be increased.

    This helps minimize noise generated from battery chargers and alternators, and voltage drop during cranking. Pilot excessive loads Many of the outputs on the EMS PRO Controller are rated for low current, control type loads. Do not run high current loads directly to the controller. Use stranded wire for hookup Solid wire transmits vibration and is more likely to crystallize and break when it is subjected to movement.

  • Page 38: Communications

    "noisy" environments. Use shielded cable on magnetic pickup Shielded cable is recommended for connecting the magnetic pickup to the EMS PRO Controller. This helps prevent signal loss and the possible coupling of electrical interference into the relatively sensitive speed sensing circuit.
  • Page 39 RS-232 RTS RS-232 CTS Description The EMS PRO implements a MODBUS RTU style communications protocol. The following will describe the communications and the register and coil implementation for the EMS PRO. Protocol The EMS PRO controller will reply to RTU MODBUS communications. This communications protocol uses RS232 standards set to 9600 baud rate, no parity, eight (8) bits and one (1) stop bit.
  • Page 40 The maximum number of registers that can be read at one time is 125. The starting address of the registers is 40001. NOTE: If a query is made to the EMS PRO controller beyond the published amount of registers, the EMS PRO controller will ignore the message as an invalid query.
