Voltage with Supply
(selection menu)
– The Analog 18 Type “Voltage with Supply” selection operates the
Analog 18 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_18 (0x3B60), then
processing the value in the VCL program.
Voltage
Analog_Input_Volts_18
0x3B60 0x00
–327.68 – 327.67V
–32768 – 32767
Read Only The analog voltage at the analog 18 input (Input 18).
Percent
Analog_Input_Percent_18
0x3B62 0x00
0.0 – 100.0 %
0 – 1000
Read Only The percentage of the voltage at pin 17 based upon the High and
Low settings, i.e., the percent of:
[(analog_input_volts_18) – (analog_input_18_low)] /
[(analog_input_18_high) – (analog_input_18_low)]
Low
Analog_Input_18_Low
0x3309 0x00
0.0 – 11.0V
0 – 1100
0.0V The minimum input voltage before a fault is declared. When the
Analog 18 Type selection is Voltage with Supply, this set point
represents the 0% point for the normalized input.
Faults:
When the voltage falls below this parameter, it will trigger
the Analog_18_OUT_OF_RANGE fault (flash code 0xBD, CAN
Index 0x262B).
If assigning the Throttle to Analog 18, the resulting fault will
become the Throttle Input fault (flash code 0x42, CAN Index
0x2210) if Throttle_Source = 18.
If assigning the Brake to Analog 18, the resulting fault will become
the Brake Input fault (Flash code 0x44) if Brake_Source = 18.
High
Analog_Input_18_High
0x330A 0x00
0.0 – 11.0V
0 – 110
5.1V The maximum input voltage before a fault is declared. When the
Analog 18 Type selection is Voltage with Supply, this set point
represents the 100% point for the normalized input.
Faults:
When the voltage rises above this parameter, it will trigger
the Analog_18_OUT_OF_RANGE fault (flash code 0xBD, CAN
Index 0x262B).
If assigning the Throttle to Analog 18, the resulting fault will
become the Throttle Input fault (flash code 0x42, CAN Index
0x2210) if Throttle_Source = 18.
If assigning the Brake to Analog 18, the resulting fault will become
the Brake Input fault (Flash code 0x44) if Brake_Source = 18.
Fault Tolerance
Analog_Input_18_Fault_
Tolerance
0x337A 0x00
0.0 – 11.0V
0 – 1100
0.0V Species the voltage threshold above the congured high limit
or below the low limit, exceeding this results in an analog out of
range fault.
For example, if High = 9.6V, Low = 1V and Tolerance = 0.2V, an
input voltage between 1V to 9.6V is mapped to 0–100%.
Voltages above 9.8V (9.6 + 0.2) or below 0.8V (1V – 0.2V) trigger
the fault.
