MicroTransII Summing Operation & Maintenance Manual
Paragon Controls Incorporated 1 Revision Level 002
1. INTRODUCTION
1.1. DESCRIPTION
The MicroTransII Summing Signal Processor employs current state-of-the-art digital microprocessor
technology to produce highly stable and accurate air flow measurements. The MicroTransII is factory
configured and calibrated to the exact specification determined at time of order. The MicroTransII
Summing Signal Processor is capable of receiving an external air flow signal (4-20mA / 0-10 VDC) ,
summing the two air flow values and displaying the MicroTransII measured air flow and the total air
flow. The MicrotransII offers an optional controller that utilizes a proprietary algorithm which results in
true three mode control incorporating proportional band, integral (reset) and inverse derivative (P, I,
1/D) controller functionality and tuning. The controller will provide responsive modulation of a control
damper or variable speed drive guaranteeing a constant airflow or pressure is maintained. Additional
optional features include AutoZero; High/Low Remote Alarms; Temperature Compensation; and
LonWorks®, BACnet®-MS/TP Master, and Modbus® Slave communication. Simple field
configuration of engineering units, operating range, process noise filtering, alarm set points, etc., are
performed via password protected intuitive menus that are accessed through the integral six button touch
pad. Device monitoring and configuration can also be performed by a building management system
through a LonWorks®, BACnet®-MS/TP Master, or Modbus® Slave communication network.
1.2. BASIC OPERATION
The transducer receives a differential pressure signal from the pressure or flow sensing element. This
signal is scaled and linearized before being displayed along with the total air flow value from an external
transmitter. The process output (4-20mA, 0-5VDC, or 0-10VDC) signal is selectable between the
MicrotransII measured air flow and the total air flow value. The AutoZero option detects and corrects
any zero offset caused by large ambient temperature changes. The Temperature Compensation option
compensates the flow and velocity signal for density changes caused by variations in the process air
temperature; an external temperature transmitter or input signal from the building management system is
required.
1.3. PI1/D CONTROL LOOP
The PI1/D controller measures the difference between the process value and the setpoint value to
determine the error value. The controller continually attempts to remove this error by varying the
control output signal to adjust the variable frequency drive (VFD) or damper. To optimize the control
loop response, the control parameters (Proportional Band [PB], Integrator Time [Reset], and Inverse
Derivative [1/D]) may need to be adjusted.
1.3.1. PI1/D Parameter Description and Response
- Proportional Band (PB): The function of the PB parameter is to amplify the current
error value (process value minus setpoint value) to make a quick control change to a large
error change. The PB adjustment range is 1 to 100%. The formula is Gain = 100% / PB.
For example, a PB setting of 100% is a gain of 1; i.e., it takes a 100% error signal to get a
full response of the controller. Conversely, a PB setting of 10% is a gain of 10; i.e., it
takes a 10% change of the error signal to get a full response of the controller. Therefore,
decreasing the PB value will cause the controller’s response to speed up.
- Integrator Time (Reset): The function of the Reset is to remove any residual error
present after the PB and 1/D functions. The Reset adjustment range is 1 to 300 seconds.
Decreasing the Reset value will cause the controller’s response to speed up.

Paragon Controls Incorporated 2 Revision Level 002
- Inverse Derivative (1/D): The function of the 1/D parameter is to filter out the noise by
delaying the controller response for a specific time period and then give a quick boost to
the control output signal. The 1/D function helps improve response and stability of the
control loop. The 1/D adjustment range is 1 to 300 seconds. Decreasing the 1/D value
will cause the controller’s response to speed up.
1.3.2. Correctly Tuned Control Loop
A correctly tuned control loop will respond to an error change quickly and return the process to the
setpoint value with minimum overshoot and oscillation, referred to as a critically damped or tuned
system (See Figure 1). The three control parameters operate in concert with each other, however each
has a specific roll in controller response.

MicroTransII Summing Operation & Maintenance Manual
Paragon Controls Incorporated 1 Revision Level 002
1.3.2.1. Poorly Tuned Control Loop
A poorly tuned control loop may respond to an error change too quickly and overshoot the setpoint
value, respond to slowly and never return to setpoint value or continually oscillate above and below the
setpoint value (See Figure 2). For an output that responds too quickly and continues to overshoot,
Paragon Controls suggests increasing the 1/D and Reset values in small increments to slow the response.
An output that gradually approaches the setpoint but never really gets there is too slow. Paragon
Controls suggests decreasing the 1/D and Reset values in small increments to speed up the response.

1.5.1. Electrical Connections
Before any electrical connections are made, ensure the POWER SWITCH is in the OFF position.
1.5.2. Static Electricity
The circuit board contains components which are susceptible to damage caused by static electrical
discharge. Should it be necessary to remove the circuit board from the enclosure, appropriate
precautions must first be taken to ensure that the operator and the circuit board are at the same electrical
potential.

5.2. OPERATING RANGE
The Operating Range allows the user to enter a value which will represent 100% of the process output
signal (5VDC, 10VDC, or 20mA). The menu will display the Maximum Full Scale Value possible for
the user to enter as the Operating Range. The Operating Range can be changed using the following
steps:
Step 1. From the active display, enter the Field Menu by pressing and holding the Enter button
for 3 seconds.
Step 2. Press the Enter button once to access the Operating Range Menu.
Step 3. Enter the new Operating Range using Up/Down/Left/Right buttons.
Step 4. Press the Enter button once.
Step 5. Press the ESC button twice.

5.3. CONTROLLER PARAMETERS
5.3.1. Tuning Parameters
The Tuning Parameters Menu allows the user to tune the controller parameters to match the system
dynamics. The Proportional Band value can be entered as a percent value from 1 to 100%. Reset and
Inverse Derivative values will range from 0 to 300 seconds. Decreasing any of the three tuning
parameter values will cause the controller’s response to speed up. Default values will be Proportional
Band = 10%, Reset (Integrator Time) = 70 seconds and Inverse Derivative = 60 seconds.
