Analog 19 menu
Parameters for 3-Wire Pot selection Reference the 3-wire potentiometer throttle section, Chapter 6.
Potentiometer 19 (wiper) & 18 (high)
Analog 19 Type
Analog_Input_19_Type
0x3311 0x00
3 Wire Pot
(selection menu)
– Selection of the 3-Wire Pot opens the Nominal Resistance parameter.
Note: When conguring Analog Input 19 as a 3-wire Potentiometer
input, it becomes the wiper (Input 19) and is paired with Analog 18
(Input 18) as the potentiometer wiper’s 5V supply voltage (high). The
Programmer app will automatically adjust the menu to match this
parameter conguration.
Nominal Resistance
Pot_19_R
0x336D 0x00
800 – 15000 Ohms 5000 Ω Set the potentiometer resistance.
Throttle or Brake potentiometers are typically 1k, 5k, or 10k Ohms.
Note: If this parameter value is outside the actual resistance, it
will trigger a Throttle Input fault (Flash code 0x42) if Throttle_
Source = 19.
Note: If this parameter value is outside the actual resistance, it will
trigger a Brake Input fault (Flash code 0x44) if Brake_Source = 19.
Analog 19 menu
Parameters for 2-Wire Pot selection Reference the 2-wire potentiometer throttle section, Chapter 6.
Potentiometer 19
Analog 19 Type
Analog_Input_19_Type
0x3311 0x00
2 Wire Pot
(selection menu)
– Selection of the 2-Wire Pot opens the Nominal
Resistance parameter.
Note: when conguring Analog input 19 as a 2-wire Potentiometer
input, the connection (pin) is both the voltage supply and wiper
input. As a 2-wire pot, one side of the potentiometer is left open
(no connection) and the other end is connected to ground (i.e., I/O
Gnd). The Programmer app will automatically adjust the menu to
match this parameter conguration.
Nominal Resistance
Pot_19_R
0x336D 0x00
800 – 15000 Ohms
800 – 15000
5000 Ω Set the nominal resistance of the potentiometer.
Throttle or Brake potentiometers are typically 1k, 5k, or 10k Ohms.
Note: If this parameter value is outside the actual resistance, it
will trigger a Throttle Input fault (Flash code 0x42) if Throttle_
Source = 19.
Note: If this parameter value is outside the actual resistance, it will
trigger a Brake Input fault (Flash code 0x44) if Brake_Source = 19.
Analog 19 menu
Parameters for Voltage with Supply selection
Analog 19 Type
Analog_Input_19_Type
0x3311 0x00
Voltage with Supply
(selection menu)
– The Analog 19 Type “Voltage with Supply” selection operates the
Analog 19 input as a raw voltage at the pin with an internal pull-
up supply voltage.
The pin’s output voltage is 10V (approx.) with a 3 mA current limit
(to the external load/device). Reference Table 10.
Use this selection for operating resistive devices such as
thermistors and photocells and reading the voltage in VCL using
the Monitor variable analog_input_volts_19 (0x3B61), then
processing the value in the VCL program.
Voltage
Analog_Input_Volts_19
0x3B61 0x00
–327.68 – 327.67V
–32768 – 32767
Read Only The analog voltage at the analog 19 input (Input 19).
