8. Sequencing Delay works to prevent inadvertent activation of HPD/SRO, which are traction
throttle based. To account for the Hydraulics_Inhibit_Type, add 64ms to compute the total delay
before the hydraulic operation will commence.

9. Set the Li Input Type to either Normally Open (NO) or Normally Closed (NC).
10. Assign the switch (input) number for the Li Input Source parameter.

Proportional Lower Command
For a proportional lower operation, setup the hydraulic throttle for the proportional valve. For the
F-series controllers, this means using an analog input assigned to the Lower operation (see Fig. 20).
is example will use Analog 18, Pot 18 Wiper, as a 2-wire lower hydraulic throttle. A voltage throttle
is similar, using the Analog 18 voltage setting versus 2-wire.
11. Set the Analog 18 Type to a 2-wire pot.
Analog 18 Type = 2-wire
Controller Setup » Inputs » Analog 18 Type
12. Set the Potentiometer 18 to the nominal resistance of the 2-wire potentiometer.
Nominal Resistance = 5000 Ohm (i.e., a typical pot resistance)
Controller Setup » Inputs » Potentiometer 18
13. Set the Lower Input Type and Lower Input Source.
Lower Input Type = 2 (Voltage Input)
Lower Input Source = 18 (corresponds to the analog 18 input, pin 17)
Controller Setup » IO Assignments » Controls » Lower Input Type & Lower Input Source.
14. Set the Lower Settings to match the 2-wire voltage responses for the application.
