Output interface, 4–20 mA
Output interface to aftermarket control systems that
support 4–20 mA. No calibration is needed.
- Slip function
Installation order (Interface Out)
NOTE! The interface works at different speeds/baud
rates, depending on whether it is used as an in or out
interface.
Connect the Y connector (2) between the PCU and
the engine, as in the figure.
Change the interface baud rate by jumpering Pin 9
and Pin 10 on the screw terminal, as in the figure.
Connect the interface to the 12-pin connector on the
Y connector, as in the figure.
NOTE! Fix the interface in a suitable place, using a
tie wrap or screw.
Throttle diode (A):
Constant light -
Input signal is valid, i.e. between 4–20 mA.
Flashes (10 Hz) -
Input signal is < 4 mA or > 21 mA.
Switched off -
Other cases.
Slip diode (B):
Constant light -
Input signal for slip is valid, i.e. between 4-20 mA.
Flashes (10 Hz) -
Input signal is < 4 mA or > 21 mA.
Switched off -
Other cases.
NOTE! Also applies to the Out interface.
