1. OVERVIEW OF CONTROLLER
1.1. Description of Single Universal Input to Proportional Valve Output Controller
This User Manual describes the architecture and functionality of the Universal Input to Single
Output Valve Controller with LED.
All inputs and logical function blocks on the unit are inherently independent from one another, but
can be configured to interact in a large number of ways. Figure 1 shows the hardware features of
the 1IN-1OUT-LED.
Figure 1 – Hardware Functional Block Diagram
The controller (1IN-1OUT-LED) is designed for versatile control of a universal input and a
proportional valve output. Its flexible hardware design allows for the controller to have a wide range
of input and output types. The sophisticated control algorithms/logical function blocks allow the
user to configure the controller for a wide range of applications without the need for custom
firmware.
The various function blocks supported by the 1IN-1OUT-LED are outlined in the following sections.
All setpoints are configurable using Axiomatic service tool, the Axiomatic Electronic Assistant (EA).
The universal input can be configured to read analog signals: Voltage, Current, and Resistance as
well as digital signals: Frequency/RPM, PWM, Digital, and Counter types. The inputs are described
in more detail in section 1.3.
Similarly, the output can be configured to different types: Proportional Current, Voltage, PWM,
Hotshot Digital Current and Digital (ON/OFF). Each output consists of a high side half-bridge driver
able to source up to 3Amps with hardware shutdown at 4Amps. The outputs are described in more
detail in section 1.5.

User Manual UMAX021610. Version: 2A 6-65
Additionally, the 1IN-1OUT-LED includes a dual LED which is visible from outside the housing. The
LED can be configured in various ways to visually inform the user of the controller’s operations.
The LED configuration is described in more detail in section 1.2.
1.2. Dual LED Output Function Block
The 1IN-1OUT-LED supports a dual LED (Green and Red). The dual LED output can be used to
inform the user of the status the controller is in.
The structure of the output block for the dual LED output is based on stages. The 1IN-1OUT-LED
provides the user with up to four different stages in order to provide more flexibility to the dual LED
output functionality.
Each of the four stages consists of its independent control source and digital response. However,
only one stage can be active at a time. For this reason, the 4-stage structure is based on priority in
which the 4th stage has the highest priority and the 1st stage has the lowest priority. In other words:
if all 4 stages are true, the response set for stage 4 will be used to drive the LED. In the instance
when none of the stages is active (ON), the Dual LED function block has another group which is
the default stage. When none of the stages are active, the user can configure the default stage to
command the LED in various ways as long as none of the stages are active.
The control sources that can be used to command each of the four stages are listed in section 1.5
Table 11. The control sources available for the dual LED output consist of the same control source
options as Table 9 with the addition of controller fault options to drive the LED. Hence, the dual
LED can be configured to be driven when a (selected) fault occurs.
The output types available for the dual LED for each stage are listed in Table1 below

User Manual UMAX021610. Version: 2A 7-65
In ‘Normal On/Off’ response type, the output command state will follow the control input command:
when the control input command is ON, the output will be turned ON and vice-versa.
In ‘Blinking Logic’ response type, the output will toggle at a period of ‘Digital Blink Rate’ for as
long as the input command is ON.
The “Control Source” setpoint together with “Control Number” setpoint determine which signal is
used to drive the output. For example setting “Control Source” to ‘Universal Input Measured’ and
“Control Number” to ‘1’, connects signal measured from Universal Input 1 to the output in
question. The input signal is scaled per input type range between 0 and 1 to form control signal.
1.3. Universal Input Function Block
The controller consists of one universal input. The universal input can be configured to measure
voltage, current, resistance, frequency, pulse width modulation (PWM) and digital signals.
1.3.1. Input Sensor Types
Table 3 lists the supported input types by the controller. The Input Sensor Type parameter
provides a dropdown list with the input types described in Table 3. Changing the Input Sensor
Type affects other setpoints within the same setpoint group such as Minimum/Maximum
Error/Range by refreshing them to new input type and thus should be changed first.

Table 3 – Universal Input Sensor Type Options
All analog input types are fed directly into a 12-bit analog-to-digital converter (ADC) in the
microcontroller. All voltage input types are high impedance while current input types use a 124Ω
resistor to measure the signal.
Frequency/RPM, Pulse Width Modulated (PWM) and Counter Input Sensor Typesare connected
to the microcontroller timers. Pulses per Revolution setpoint is only taken into consideration when

User Manual UMAX021610. Version: 2A 8-65
the Input Sensor Type selected is one of the frequency types as per Table 3. When Pulses per
Revolution setpoint is set to 0, the measurements taken will be in units of [Hz]. If Pulses per
Revolution setpoint is set to higher than 0, the measurements taken will be in units of [RPM].
Digital Input Sensor Types offers three modes: Normal, Inverse, and Latched. The measurements
taken with digital input types are 1 (ON) or 0 (OFF).
1.3.2. Pullup / Pulldown Resistor Options
With Input Sensor Types: Frequency/RPM, PWM, Digital, the user has the option of three (3)
different pull up/pull down options as listed in Table 4.
0

Table 4 – Pullup/Pulldown Resistor Options
These options can be enabled or disabled by adjust the setpoint Pullup/Pulldown Resistor in the
Axiomatic Electronic Assistant.
1.3.3. Active High / Active Low Options
In the case of Digital Inputs, the options Active High/Active Low are used to configure how a
signal high or signal low is interpreted. The following table below are the available options
provided. By default, Active High is selected.

1.3.4. Counter Type
The 1IN-1OUT-LED controller supports three different variations of the Counter input type. These
variations are listed in Table 7 below:
0
Pulses Within Measuring Window
1
Time Measurement of Pulse Count
2
Trigger on Pulse Count Completion
Table 7 – Counter Input Types
The first option Pulses Within Measuring Window is used to count the number of pulses that occur
within a configurable time frame (Measuring Window) in terms of milliseconds. This particular
Counter type uses the other setpoint Measuring Window to select the time frame in which pulses
are to be counted.
Time Measurement of Pulse Count is another option which allows time measurement of selected
number of pulses to occur. Time measurement can be from 0ms to 65,000ms. If the time
measurement has reached it maximum but not yet counted the selected number of pulses, the
time will remain at maximum value. Therefore, it is important to select a number of pulses which
could occur within the maximum time frame. Once the selected number of pulses have been read,
the time will be restarted until the pulses have been read.
Trigger on Pulse Count Completion is Counter input type which triggers an ‘ON’ signal as soon as
the selected number of pulses have been read. Setpoints Pulses to Count, Edge to Trigger
Pulse and Trigger on First Pulse work together in this particular Counter type. When the
controller reads all pulses in Pulses to Count, the input will be triggered ‘ON’ until the next pulse is
received which will reset the trigger to ‘OFF’. The setpoint Edge to Trigger determines on which
edge of the pulse is the pulse count to be incremented. If the edge selected is Falling Edge, then
the pulse count will not be incremented until the falling edge of the pulse is received. Likewise, if
the selected edge is Rising Edge, then the pulse count will be incremented as soon as the rising
edge of the pulse is received. The other setpoint is Trigger on First Pulse. This setpoint gives the
user the option of triggering on the first pulse counted or the last pulse counted in Pulses to
Count.
For example, if Pulses to Count is set to 100, Edge to Trigger is set to Rising Edge and Trigger
on First Pulse is set to TRUE, then the rising edge of the first pulse will trigger an ‘ON’ signal. The
signal will remain ‘ON’ until the rising edge of the second pulse is received which turns the signal
to ‘OFF’. After a count of another 100 pulses is met, the signal will turn back ‘ON’ and the cycle
starts again.
1.3.5. Minimum and Maximum Ranges
The Minimum Range and Maximum Range setpoints are used to create the overall useful range
of the inputs. For example if Minimum Range is set to 0.5V and Maximum Range is set to 4.5V,
the overall useful range (0-100%) is between 0.5V to 4.5V. Anything below the Minimum Range
will saturate at Minimum Range. Similarly, anything above the Maximum Range will saturate at
Maximum Range. In order to generate an input fault if the measured input falls output of the
Minimum Range or Maximum Range, the Diagnostics function block can be used. Please refer to
Section 1.8 for more details.

User Manual UMAX021610. Version: 2A 10-65
1.3.6. Input Software Filter Types
All input types with the exception of Digital (Normal), Digital (Inverse), Digital (Latched) can be
filtered using Filter Type and Filter Constant setpoints. There are three (3) filter types available
as listed in Table 8.
0
No Filtering
1
Moving Average
2
Repeating Average
Table 8 – Input Filtering Types
The first filter option No Filtering, provides no filtering to the measured data. Thus the measured
data will be directly used to the any function block which uses this data.
The second option, Moving Average, applies the ‘Equation 1’ below to measured input data, where
ValueN represents the current input measured data, while ValueN-1 represents the previous filtered
data. The Filter Constant is the Filter Constant setpoint.
Equation 1 - Moving Average Filter Function:
The third option, Repeating Average, applies the ‘Equation 2’ below to measured input data, where
N is the value of Filter Constant setpoint. The filtered input, Value, is the average of all input
measurements taken in N (Filter Constant) number of reads. When the average is taken, the
filtered input will remain until the next average is ready.
Equation 2 - Repeating Average Transfer Function:
1.4. Internal Function Block Control Sources
The 1IN-1OUT-LED controller allows for internal function block sources to be selected from the list
of the logical function blocks supported by the controller. As a result, any output from one function
block can be selected as the control source for another. Keep in mind that not all options make
sense in all cases, but the complete list of control sources is shown in Table 9.
