Pin 7 Speed Limit 3 / Handbrake -- Pump Inhibit
Traction Speed Limit 3 / Handbrake
This input is primarily intended to be used with a handbrake switch, however, its function can be set by the
programmable parameter “M3-6T I/O Pin 7 ”Spd3/Hbk””.
If set to Spd3 (0), then this input can be used to limit the speed of the vehicle to a value set by the programmable
parameter. The speed limit will occur when the switch is open. The speed will be limited to the setting “M1-44T
Cutback speed 3 (I/O 7 set to speed3) “Speed3”” .
If set to Hbk (1), then this input should be connected to the vehicle’s handbrake switch. When the switch is closed,
i.e. the handbrake is on, the vehicle’s speed will be set by the parameters “M1-45T Handbrake On maximum Speed
(I/O 7 set to Handbrake) “HandBrk”” and “M1-46T Maximum Drive Torque speed 3 (I/O 7 set to Handbrake)
“MxDrTrq3””.
Pump: Pump Inhibit
This input can be used to inhibit pump operation. So when input 7 is active the pump is stopped.
The polarity of the switch can be set by means of parameter “M3-3P Inhibit input normally closed or normally open
“HibNO/NC”.
If set to 0, the input is active when switch is closed.
If set to 1, the input is active when switch is open.
Pin 8 Analogue supply 5V
A supply for 5kΩ Potentiometers is available to this pin with max 10mA capability for sourcing current.
Pin 9 Analogue AD1 i/p Accelerator -- Potentiometer
Traction
This is an analogue input that will accept a 3-wire 5kΩ potentiometer or a 0V to 5V voltage signal (electronic
accelerator).
The active range of the accelerator input is defined by the programmable parameters, “M1-52T Accelerator pot
minimum “AccMin”” and “M1-53T Accelerator pot maximum “AccMax””.
Two kinds of accelerator can be selected by means of parameter “M3-12T Accelerator type ”AccelTyp””.
If AccelTyp is selected to (0) normal, the first parameter “AccMin” sets the voltage that relates to zero drive
demand, the second, “AccMax” sets the voltage that corresponds to 100% drive demand.
If AccelTyp is selected to (1) WigWag, “AccMin” sets 100% reverse drive demand from the Throttle, “AccMax” to
100% forward drive demand from the Throttle.
If the operation of the wig-wag pot is reversed, swap the two supply leads of the potentiometer. Transposing the
parameter values will result in a fault. The voltage admittable range is from 0.2V to 4.5V. Outside this range, a
failure is signaled (F28 S004).
Pump
This is an analogue input that will accept a 3-wire 5kΩ potentiometer or a 0V to 5V voltage signal (electronic
potentiometer).
This input has to be connected to the pump’s potentiometer.
The active range of the input is defined by the programmable parameters “M1-14P Accelerator pot minimum
”AccMin”” (0% Pump Speed) and “M1-15P Accelerator pot maximum ”AccMax”” and it corresponds to the speed
set in the parameter “M1-5P Maximum pot speed 1 ”Potmax1””. The potentiometer is working in conjunction with
input 1 “Pin 1 Forward i/p -- Pump Potentiometer Switch 1” if it is enabled.
Pin 10 Analogue supply 0V
This input is the analog input ground for potentiometers.
