OVERVIEW

FMS-1650 Overview

The touch-screen user interface of the FMS-1650 room pressure
controller is designed to facilitate the initial setup and configuration,
diagnosis, and troubleshooting during the installation process. Each
menu screen is limited to four options, thereby simplifying navigation
through the menu system. Context-sensitive help (Figure 2) is
available at most menu screens and is accessed simply by touching
the menu title on that screen. To exit from any help screen, simply
touch the display anywhere on the popup. Multi-page menu screens
have navigation buttons at the bottom of each screen that allow the
user to move forward or backward, and include a convenient exit
button on the last screen (Figure 1) to quickly exit the menu system to
return to the main display.

To preserve the security of the configuration settings, up to ten (10)
multilevel passwords may be programmed to prevent unauthorized
access to the system configuration settings. To further prevent
unauthorized access, the FMS-1650 user menu system incorporates
display timeout periods based on the screen currently displayed. Menu
screens timeout after 90 seconds of inactivity, while popup screens
automatically timeout after 60 seconds. This prevents unauthorized
access to the menus should a unit be inadvertently left unattended at
one of the user menus or configuration screens.

MAIN SETUP MENU

Introduction

FMS-1650

The Main Setup menu provides four options for 1) configuring
the settings specific to the unit as a room pressure controller, 2)
configuring the settings associated with the additional hardware
resources, as well as managing the system security passwords, 3)
configuring the display-specific settings, and 4) using the diagnostics
and troubleshooting resources (Figure 3).

Figure 3. Main Setup
menu provides access
to configuration of all
FMS-1650 settings.

analog input, setting the system time and date, selecting the language
for the user interface, and adjusting the brightness of the touch screen
display. The FMS-1650 can simultaneously display the differential
pressure, ambient temperature, relative humidity, and air change rate
for the monitored room in real-time. The sources for each of these
displayed parameters may easily be specified using Display Options
on the Display Setup menus.

The Diagnostics options provide information specific to this particular
FMS-1650 unit, assistance with the troubleshooting of the unit, and
real-time confirmation of the signals connected to the backplane.
The Overrides option on the Diagnostics menus allows the analog
outputs and relay outputs to be manually overridden independently
to assist with verifying the correct operation and/or allocation of the
controller resources. There are two options that provide support for
zero-calibrating the FMS-1650 once it has been installed, to ensure
maximum accuracy of the displayed differential pressure readings. To
further assist with troubleshooting the FMS-1650 during the installation
phase, the Real-Time View option on the Diagnostics menus allows the
user to view the real-time conditions of each of the resources attached
to the FMS-1650 controller.

More information on each of the four options on the Main Setup Menu
is available in subsequent sections of this guide. The next section
covers the options available on the Unit Setup menu.

If this FMS-1650 is being used primarily as a room pressure controller
monitoring a single room, then the majority of the configuration settings
will be available through the Unit Setup option on the Main Setup
Menu. The options for configuring the additional hardware resources
available on the FMS-1650 may be accessed through the System
Setup options. These additional hardware resources include universal
analog inputs 2 through 4, dedicated thermistor inputs 1 and 2, analog
outputs 2 through 4, digital inputs 2 through 4, and relay outputs 2
through 4. Other additional resources available through the System
Setup options include the secondary PID control loops associated with
analog outputs 2 through 4, the comprehensive alarm facility, and the
security password management facility.

The Display Setup option has six options available for configuring all
of the display-specific settings integrated in the FMS-1650. These
options include setting the primary display mode, selecting the
individual display options, defining the names associated with each

Configuring Controller Settings

The Unit Setup menu shown in Figure 4 provides support for:

1. Configuring the controller settings

2. Configuring the settings associated with the room being monitored

and/or controlled

3. Configuring the network-specific settings of the controller module

4. Using options for sharing configuration data between this

controller and another controller on the same network

Figure 4. Unit Setup
menu provides options
for configuring the
controller settings,
room settings, network
settings, and sharing
configuration data.

If the FMS-1650 is being used primarily as a room pressure controller,
the Room Setup option provides access to the settings associated with
the spaces being monitored and/or controlled. Options available on
the Isolation Room Setup menu include selecting the mode of isolation,
the state of occupancy of the monitored space, and defining the name
associated with each space or room being monitored and/or controlled.

The Network Setup option provides support for configuring the settings
associated with the networking capability of the FMS-1650. These
options include selecting the baud rate for the network interface (if
the current protocol is BACnet MS/TP), setting the network or MAC
address for the unit, and setting several parameters specific to the
BACnet® protocol such as the device ID offset and the Max_Master
parameter. The available options on the Network Setup menu strictly
depend on the protocol selected at the controller module via hardware
configuration switch settings. More information on the two different
sets of menu options is given in the Configuring Network Settings
section later in this document.

To share configuration data with other controllers on the same
RS-485 network, the Share Configuration option provides support for
accomplishing this task. These options include specifying the address
to which configuration data should be sent, putting the unit into receive
mode waiting for configuration data from another unit on the same
network, and displaying the configuration data associated with this
specific unit. Currently, these options have been reserved for factory-

use only, but are expected to be made available to end users in a
future release of the FMS-1650 firmware. Consult the factory for more
information on this feature.

The Controller Setup options provide access to facilities for configuring
all of the settings associated with the FMS-1650 when primarily being
used as a room pressure controller. This includes setting up the
analog input and output, door switch, alarm relay, PID control loop,
alarm setpoints, audible alert settings, and the engineering units for
the differential pressure reading. If the FMS-1650 is being used with
multiple differential pressure sensors, the Controller Setup options
allow the primary sensor to be configured, while the System Setup
options must be used to configure the secondary sensor(s).

FMS-1650

The Controller Setup menus shown below in Figure 5 and Figure 6
provide access to facilities for configuring all of the settings associated
with the FMS-1650 when it has been set up as a room pressure
controller, including setting up the analog input and output, configuring
the door switch input, setting up the alarm relay, configuring the PID
loop settings, alarm setpoints, audible alert settings, and selecting the
engineering units for the differential pressure reading.

Figure 5. The
Controller Setup
menu (2 of 2) allows
the capabilities of the

Setting up the Main Sensor Input

The Analog Input option on the Controller Setup menus allows
the primary differential pressure sensor input to be configured as
required by the specific application. Selecting this option invokes
the Sensor Input Settings configuration screen shown in Figure 8. At
this configuration screen, the user may specify whether or not the
linearization of the sensor input should be enabled, and whether or
not to invert the analog input signal. The Inverted Mode option is very
useful if the actual remote sensor connected to the FMS-1650 was
installed backwards inadvertently, such that the reference and monitor
ports of the pressure sensor are reversed. Selecting the Inverted
Mode is equivalent to manually reversing the tubing at the remote
sensor ports.

UNIT SETUP

Confi guring Controller Settings

Setting up the Damper Control Output

The Analog Output option on the Controller Setup menus allows the
primary control output to be configured as required by the specific
application. Selecting this option invokes the Analog Output Settings
configuration screen (Figure 10). Each of the four (4) analog outputs
of the FMS-1650 may be configured for one of two operating modes:
Direct Analog Output or PID Analog Output.

The direct analog output or proportional mode allows the output to
track the mapped analog input directly or inversely. The PID mode
employs the proportional-integral-derivative scheme for closed-loop
control of the analog output. Independent of the mode for which the
analog output is configured, the range of the output may or may not
include an offset.

Clicking the Next button invokes the Sensor Input Settings
configuration screen shown in Figure 7, where the engineering units
may be selected, as well as the voltage or current range for the sensor
input. For internal sensor models (FMS1650-F-1-x), the sensor input
defaults to the 0-5V range, and clicking the Next button invokes the
Enter XX-ISO Setpoint configuration screen. For remote sensor
models (FMS1650-x-0-1), the sensor input defaults to the 4-20mA
range.

Clicking the Next button invokes the AI-1 Sensor Range configuration
screen as shown in Figure 9, where the pressure range associated
with the remote sensor may be specified. The default pressure range
for all standard FMS-1650 models is ±0.25 “WC, although existing
remote sensor units may have pressure ranges that match one of the
other choices on this setup screen. Once the pressure range has been
specified, the user is prompted to enter the setpoint for the current
isolation mode.

Selecting the 0-5V,0-10V,0-20mA range allows the analog output to
swing from zero to the maximum specified by the hardware dipswitch
selection, while the 1-5V,2-10V,4-20mA range includes an offset from
zero.

Figure 10. Proportional
(direct) and PID analog
output modes are
supported.

Once the operating mode and output range have been specified, the
next Analog Output Setup configuration screen prompts the user to
specify the minimum and maximum limits for the analog output in
percentage (Figure 11). The default minimum and maximum are zero
and 100 percent, respectively. This allows the analog output to not
exceed or go below a predetermined voltage or current output.

Clicking the Next button invokes the last Analog Output Settings
configuration screen (Figure 12), where the user can specify the
analog input to which this analog output should be mapped, and
select the action mode for the analog output. The default setting uses
AI-1 as the analog input channel for the analog output. The action
mode determines the direction in which the output is driven based on
the sensor input (AI-1). The default action mode is Direct Acting for
positive isolation and Reverse Acting for negative isolation. Neutral
isolation mode defaults to Direct Acting mode for the primary analog
output.

lower limits for each
analog output may be

FMS-1650

Setting up the Door Switch

The FMS-1650 uses digital input 1 (DI-1) as the door switch input for
the primary isolation room. This capability allows the FMS-1650 to
monitor the door to the monitored room and use the status of the door
to delay the sounding of alarms and/or hold the analog output fixed
until the door returns to the closed position. The Door Switch option
on the Controller Setup menus allows the door switch input to be
configured as required by the specific application. Selecting this option
invokes the Door Switch Settings configuration screen shown below
(Figure 14).

The door switch input may be configured for one of two modes:
Normally-Open or Normally-Closed. While any suitable switch may
be used with the FMS-1650, the door switch provided by Triatek (part
no. SWD200-2) supports both normally-open (N.O.) and normally­closed (N.C.) operating modes. After selecting N.O. or N.C. for the
door switch, set the delay as required by the specific installation. The
default value for the door delay is zero seconds, but can be as long as
180 seconds, or three minutes.

UNIT SETUP

Confi guring Controller Settings

Figure 14. Door
switch may be set for
N.O. or N.C. contacts,
or disabled at the

Setting up the Alarm Relay

When the door to the monitored room opens, the door delay timer
begins counting down, and inhibits the alarm buzzer and alarm relay
from triggering until the timer expires. If the audible alert is configured
with a delay, the door delay counts down first, and then the audible
alert delay begins timing. Similarly, if the alarm relay has a delay
associated with it, it begins counting down after the door delay expires.

Figure 13. Relays
may be triggered by
one of three methods,
and may include an
activation delay.

The FMS-1650 uses relay output 1 (RL-1) as the alarm relay output
for the primary isolation room. This capability is typically used to allow
the FMS-1650 to trigger a remote alarm annunciator. The Relay Setup
option on the Controller Setup menus allows the alarm relay output to
be configured as required by the specific application. Selecting this
option invokes the Relay 1 Trigger Mode configuration screen shown in
Figure 13. The alarm relay output may be configured to be triggered
in one of three modes: Setpoints, Isolation Mode, or Occupancy Mode.
Setpoints Mode uses a pair of setpoints to determine when to activate
or deactivate the alarm relay. Isolation Mode allows the alarm relay
to be triggered based on the mode of isolation selected. Occupancy
Mode uses the state of occupancy to determine when the alarm relay
should be active or inactive.

Isolation Mode and Occupancy Mode are currently unavailable as
trigger modes for the FMS-1650, but may be enabled in a future
firmware release. When using Setpoints trigger mode, the unit must
be in either positive or negative isolation mode in order to enter the
high and low relay setpoints. If the unit is in neutral isolation mode,
then setpoint entry will not be available.

If Setpoints Mode is selected as the trigger mode for the alarm relay,

the user is next prompted for the Input Channel to use for analyzing
the relay setpoints. While relay output 1 uses Analog Input 1 by
default, it may be remapped to any one of the four universal analog
inputs (AI-2 through AI-4) or either of the two dedicated thermistor
inputs (TI-1 and TI-2). After selecting the desired input channel, the
user is next prompted for high and low relay setpoints for the current
isolation mode.

The high setpoint determines the threshold at which the alarm relay
gets activated if in direct acting mode, or gets deactivated if in reverse
acting mode. The low setpoint determines the threshold at which the
alarm relay gets deactivated if in direct acting mode, or gets activated
if in reverse acting mode. After specifying the high and low setpoints,
the user is prompted for the acting mode and delay associated
with the alarm relay. In direct acting mode, the alarm relay will be
activated when the sensor input exceeds the high setpoint, and will
be deactivated when the sensor input falls below the low setpoint. In
reverse acting mode, the alarm relay will be deactivated when the
sensor input exceeds the high setpoint, and will be activated when the
sensor input falls below the low setpoint. The alarm relay delay may
be up to 180 seconds, or three minutes, in duration.

If Isolation Mode is selected as the trigger mode for the alarm relay,
the user is next prompted to select whether the alarm relay should
activated or deactivated for each mode of isolation. Next, the user
is prompted for the acting mode and delay to be associated with the
alarm relay. If the FMS-1650 has been configured for a door switch
with a delay setting greater than zero, then the door switch delay will
count down before the alarm relay delay will begin counting down.
Otherwise, the alarm relay delay will begin counting down immediately
after the trigger condition is achieved, and the alarm relay will activate
or deactivate when the timer expires, depending on the acting mode
selected for the alarm relay. Isolation Mode is not available as a
selectable option, and will not be accepted if it is selected. This option
may be made available in a future firmware release. Contact the
factory for details.

Adjusting the PID Loop Settings

When the FMS-1650 is configured to use analog output 1 for closed­loop control applications, the proportional, integral, and derivative
constants that determine the performance and characteristics of the
control scheme may be specified using the PID Loop Setup option on
the Controller Setup menus. Selecting this option invokes the PID
Loop Settings configuration screen as shown in Figure 16, where
the user can fine-tune the PID constants to be used by the closed­loop control scheme for analog output 1. These three dimensionless
constants may vary from zero to 100 using the three sliders on the
configuration screen. See the PID Tutorial in the appendix at the end
of this document for more information on fine-tuning the PID constants
for a specific application.

Configuring the Alarm Parameters

The FMS-1650 allows the user to specify multiple alarm setpoints for
each analog input. The Alarm Limits option on the Controller Setup
menus allows the high and low alarm setpoints to be configured as
required by the specific application. Selecting this option while the
unit is in positive isolation mode invokes the Pos ISO High Alarm SP
configuration screen shown in Figure 15. If the unit is in negative
isolation mode, selecting the Alarm Limits option invokes the Neg
ISO High Alarm SP configuration screen shown in Figure 18. If the
unit is in neutral isolation mode, then the alarm setpoints cannot be
configured, and the warning message shown in Figure 17 is displayed.

mode must be
currently active to
enter alarm setpoints.
Otherwise, this
message is displayed.

After entering the high alarm setpoint, the user is subsequently
prompted for the high warning setpoint, low warning setpoint, and
low alarm setpoint. These four setpoint values must be sequentially
decreasing or increasing in magnitude to be valid, depending on the
selected isolation mode.

Max_Master parameter to 30 limits the addresses which must be
polled periodically by each master node on the network. Each master
node polls for new master nodes periodically, which allows BACnet®
devices to be auto-discovered. It is recommended that the Max_
Master parameter be left at the default value so that future devices
can be added to the network without having to reset the Max_Master
parameter at each device.

Selecting the Protocol Options option on the Network Setup menu
invokes the BACnet® Protocol Setup menu shown in Figure 31. The
DeviceID Offset option allows the user to specify an device instance
offset from zero to 4,9140,000 (Figure 30).

The device instance number that uniquely identifies a BACnet®
device within a network of devices is calculated as the sum of the
MAC address and the DeviceID offset value. For example, if the
DeviceID offset is set to the default value of 85,000 and the current
MAC address is 123, then the device instance number which uniquely
identifies this particular FMS-1650 on the network is 85,123.

The Max_Master option on the BACnet® Protocol Setup menu allows
the user to specify a new value for the Max_Master parameter used by
the BACnet® MS/TP protocol (Figure 32). This parameter specifies
the highest allowable address for a master node on the same network.
The default value for this parameter is 127. Setting this parameter to a
value lower than the default reduces the number of addresses that are
polled by each master node on the network, which effectively improves
the overall networking efficiency. Use the slider to specify a new
Max_Master value. The blue increment and decrement buttons may
be used to change the displayed value one step at a time.

For example, if there are at most 25 master mode devices on a given
network, and they are addressed between 1 and 30, then setting the

Introduction

The System Setup menus provide support for configuring all of the
hardware resources on the FMS-1650. The first page of the System
Setup menu as shown in Figure 35 provides options for configuring
the four universal analog inputs, two dedicated thermistor inputs, four
universal analog outputs, and the four relay outputs.

The second page of the System Setup menu as shown in Figure 36
provides options for configuring the four (4) PID loop settings, all of
the alarm settings, specifying the engineering units for each analog
input, and managing the system security passwords. Several of the
configuration options on the System Setup menus specific to the
hardware resources are redundant with those on the Controller Setup
menus.

Setup menu (2 of 2)
provides options for
configuring engineering
units, alarm settings,
and managing the
system passwords.

Figure 35. System
Setup menu (1 of 2)
provides options for
configuring the analog
and digital inputs/
outputs.

The Analog Inputs option on the System Setup menus allows the
additional universal analog inputs on the FMS-1650 to be individually
configured based on the mode selected for each. Each of the
secondary universal analog inputs (AI-2 through AI-4) may be
configured for differential pressure, volumetric flow, relative humidity,
or temperature setpoint adjust. When using one of the dedicated
thermistor inputs for temperature control applications, any one of the
secondary analog inputs may be configured for use with a thermostat
slider to serve as a temperature setpoint offset adjustment.

The Analog Inputs option on the System Setup menus also allows the
two (2) thermistor inputs to be configured as required by the specific
installation, including target setpoints for each should they be utilized
as the input channel for one of the PID control outputs, e.g., for
temperature control applications.

The Analog Outputs option on the System Setup menus allows
the additional universal analog outputs on the FMS-1650 to be
individually configured. Each of the secondary analog outputs may be
configured for proportional (direct) analog output mode or PID analog
output mode. As with the primary analog output (AO-1), each of the
secondary analog outputs may be independently mapped to any of the
available analog inputs. This includes any one of the four (4) universal
analog inputs or either of the two (2) dedicated thermistor inputs. Each
analog output may also be configured for either direct acting or reverse
acting mode as required by the specific application.

The Digital Inputs option on the System Setup menus allows the
additional digital inputs on the FMS-1650 to be individually configured.
Each of the secondary digital inputs may be configured for one of four
input types: door switch, occupancy switch, override switch, or auxiliary
input. Currently, only the door switch input type is available as an
option for the secondary digital inputs. The other digital input types will
be supported in a future firmware release for the FMS-1650.

The Relay Setup option on the System Setup menus allows the

additional relay outputs on the FMS-1650 to be individually configured.
As with the primary relay output, each of the secondary relay outputs
may be configured for one of three trigger modes: Setpoints, Isolation

Mode, or Occupancy Mode.

• Setpoints Mode uses a pair of setpoints to determine when to

activate or deactivate the alarm relay.

• Isolation Mode allows the alarm relay to be triggered based on the

mode of isolation selected.

• Occupancy Mode uses the state of occupancy to determine when

the alarm relay should be active or inactive.

The PID Loop Setup option on the System Setup menus allows the
additional PID control loops to be individually configured based on the
requirements of the specific application. Each of the secondary PID
control loops is directly associated with the corresponding secondary
analog output. As with the primary PID loop settings, the three
constants (proportional, integral, derivative) may be independently
tuned for the desired response at each analog output.

The Alarms Setup option on the System Setup menus allows all of the
settings associated with the alarm functionality of the FMS-1650 to
be configured independently. This includes all of the individual alarm
enables, alarm setpoints, and alarm buzzer enables. The flexibility
of the alarm capabilities incorporated in the FMS-1650 is unmatched
in the industry, and can be tailored to meet most any specification
requirements.

The Engineering Units option on the System Setup menus allows the
user to select between Imperial and Metric units for each analog input
resource, including the two thermistor inputs. The default selection is
Imperial units for all analog inputs.

The Passwords Setup option on the System Setup menus allows the
user to manage the system security password facility that has been
incorporated into the FMS-1650. Up to ten (10) unique multiple access
level passwords may be stored in the unit to prevent unauthorized
access to the system menus and configuration settings.

The next section details the options available on the Analog Inputs
Setup menus.

Configuring Secondary Analog Inputs

Selecting one of the secondary analog inputs from the Analog Inputs
Setup menu invokes the Select Input Type configuration screen as
shown in Figure 37. If Analog Input 1 is selected, the same options
that are accessed through the Controller Setup menus are traversed
(Figure 7 through Figure 9).

Setting Up Analog Inputs for Pressure

To configure one of the secondary analog inputs for differential
pressure, select Pressure from the Select Input Type configuration
screen (Figure 37) and click the Next button.

The Pressure Sensor Input configuration screen appears where the
user may specify the type of pressure sensor being used. There
are two types of Triatek pressure sensors, and an option for using
a non-Triatek pressure sensor. The two Triatek types are Remote
Digital 4-20mA, which uses a standard 4-20 mA current output to
represent the full pressure range, and Remote Legacy Current, which
uses a non-standard 7.8-19.55 mA current output. The legacy sensor
option provides the FMS-1650 with complete backward-compatibility
with Triatek’s legacy remote pressure sensors. After specifying the
pressure sensor type, click Next to advance to the Analog Input
Settings configuration screen, where the user may specify whether
or not the linearization of the analog input should be enabled, and

whether or not the analog input signal should be inverted. The
Inverted Mode option is useful for those situations where the remote
sensor was installed backwards with the reference port facing the
monitored space instead of the reference space. Clicking the Next
button invokes the next Analog Input Settings configuration screen
where the displayed engineering units may be specified, as well as the
voltage or current range for the analog input signal.

For all Triatek remote sensor units, the default pressure range is ±0.25
“WC and the input range should be set to 4-20mA. Clicking the Next
button invokes the AI-x Sensor Range configuration screen (Figure 9)
where the pressure range associated with the remote sensor should
be specified. Once the pressure range has been specified, the user
is prompted to enter a setpoint for the currently active isolation mode,
as well as the deadband setting to be used for all modes. The default
deadband setting is zero.

Setting up Analog Inputs for Flow

The FMS-1650 can be configured to calculate and display the real-time
Air Change Rate using one of three types of air flow input methods or
sensors. To configure one of the secondary analog inputs for air flow
measurement, select Flow from the Select Input Type configuration
screen as shown in Figure 38 and click the Next button. The Flow
Sensor Input configuration screen shown in Figure 39 appears,
allowing the user to select which type of sensor will be used for
measuring air flow.

Figure 38. To calculate
& display air change
rate, input should be
configured for flow.

After selecting the type of sensor that is being used to measure
air flow, clicking the Next button invokes two configuration screens
(Figure 40) which allow the user to specify the minimum and maximum
flows supported by the sensor. These values should be entered in
the engineering units which correspond to the type of sensor. For
example, the units would be either inches of water column (“WC) or
Pascals (Pa) for DP transmitters.

Figure 39. FMS-1650
supports three types
of sensors for Air Flow
measurement.

After specifying the maximum and minimum for the flow input, the
user is prompted to specify the cross-sectional duct area in square
inches as shown in Figure 43 if the type of flow sensor is either a
DP transmitter or a velocity transmitter. This duct area is required to
convert a differential pressure or a velocity to a real-time volumetric
flow, which may then used to calculate the air change rate (if enabled).
For round ducts, the cross-sectional area can be determined by
multiplying the square of the radius by pi (3.1416). As an example, the
cross-sectional area of a round 12” duct, which has a radius of 6”, is
calculated as follows:

Area

= π * r2 = 3.1416 * (6”)2 = 113.09 in

TRIATEK reserves the right to change product specifications without notice.

For rectangular ducts, the cross-sectional area can be determined by
multiplying the length and width. As an example, the cross-sectional
area of a duct that measures 24” by 12” is calculated as follows:

SYSTEM SETUP

Confi guring Secondary Analog Inputs

After specifying the duct cross-sectional area, click the Next button
to specify a K-factor for the specific sensor being used to input flow.
The default value for this K-factor is 1.0, but may be provided by the
manufacturer of the sensor to serve as a correction factor for the actual
output of that particular sensor unit. If no K-factor is available, this
value should be left at the default of 1.0.

Clicking the Next button invokes the Analog Input x Settings
configuration screen as shown in Figure 41, where the user may
specify whether or not air changes should be calculated and displayed
on the main screen, as well as the range of the input signal (voltage
or current) for the air flow sensor. If the air changes have been
selected for display, the user is prompted to enter the room volume in
cubic feet at the Enter Room Volume configuration screen shown in
Figure 42. The room volume is required to calculate the real-time air
change rate based on the flow input signal. To calculate the volume
of a rectangular room in cubic feet, multiply the length of the room by
the width and the height. For irregular shaped rooms, the volume will
have to be determined by breaking the room up into multiple smaller
rectangular areas and summing the individual volumes to calculate the
total room volume in cubic feet. Otherwise, an approximation may be
specified for the room volume. This volume may also be fine-tuned to
increase the accuracy of the displayed air change rate according to the
actual volumetric flow offset of the room.

thermistors. These inputs may be configured for use with negative
temperature coefficient (NTC) Type 2 or Type 3 thermistors from BAPI®
or other manufacturers.

BAPI® manufactures several combination temperature and
humidity sensor products which are ideal for use with the FMS­1650 for complete room monitoring and control applications.
Triatek recommends BAPI® part no. BA/10K-2-H200-R, which is a
combination temperature and humidity sensor includes a NTC Type 2
thermistor for temperature sensing and a ±2% humidity transmitter with
a 0 to 10V output.

outputs may each be mapped to the same analog input, which may
each have their own specific setpoints associated for their particular
application.

For example, two analog outputs may use the primary differential
pressure input on AI-1 to satisfy two different control objectives. AO-1
may control the exhaust valve to maintain a target differential pressure
whenever the pressure is within a specific range. Simultaneously,
AO-2 may control the supply valve to maintain a specific volumetric
offset between the supply and the exhaust.

SYSTEM SETUP

Confi guring Secondary Digital Inputs

FMS-1650

Selecting one of the secondary digital inputs from the Digital Inputs
Setup menu invokes the Select Input Type configuration popup as

shown in Figure 54. The user may select the operating mode and
polarity for this digital input resource. The selection between active­high and active-low mode for the digital inputs is a global hardware
configuration setting and is accomplished using the configuration slide
switch (S5) on the controller module. See the FMS-1650 Wiring and
Installation Guide for complete details on configuring the digital input
hardware resources.

Each of the secondary digital inputs may be configured for one of four
types: door switch, occupancy switch, override switch, or auxiliary
input. The latter two options are unavailable at this time and may not
be selected. These options may be implemented in a future firmware
release for the FMS-1650. If door switch is selected as the input
type for one of the secondary digital inputs, that input may be used to
suspend the PID control loop processing for the corresponding analog
output. For example, DI-2 configured as a door switch input will allow
the PID loop processing for AO-2 to be suspended whenever the door
monitored by DI-2 is open. Once Door Switch has been selected at
the Select Input Type configuration screen, clicking the Next button
invokes Door Switch Settings configuration screen (Figure 14). The
door switch input may be configured for one of two modes: Normally-
Open or Normally-Closed. While any suitable switch may be used with
the FMS-1650, the door switch provided by Triatek (part no. SWD200-

2) supports both Normally-Open (N.O.) and Normally-Closed (N.C.)
operating modes.

configuration screen, which allows the user to specify which mode of
isolation should be active when the room is occupied. When the digital
input configured as an occupancy switch returns to the inactive state,
the isolation mode automatically switches back to neutral mode.

Figure 54. Secondary
digital inputs may be
used for a variety of
applications.

After selecting N.O. or N.C. as the operating mode for the door switch,
set the delay as required by the specific installation. The default value
for the door delay is zero seconds, but may be as much 240 seconds,
or 4 minutes. When the door to the monitored room opens, the
associated PID control loop is suspended, preventing the controlled
valve from being modulated unnecessarily while the door is open.
Once the door closes, the door delay timer begins counting down, and
releases the PID control loop once it expires and resumes modulating
the controlled valve to maintain the differential pressure target setpoint.

Configuring one of the secondary digital inputs for Occupancy Switch
mode allows an external signal, either from an occupancy switch or
sensor, or a relay output, to switch the mode of isolation between
neutral and either positive or negative. Clicking Next after selecting
Occupancy Switch as the input type invokes the Occupied Mode

Confi guring Secondary Relay Outputs

Selecting one of the secondary relay outputs from the Relay Setup
menu invokes the Relay x Trigger Mode configuration popup as shown
in Figure 56. The user may select one of three trigger modes for this
digital output resource: Setpoints, Isolation Mode, or Occupancy Mode.
Currently, the only available option for triggering the relay outputs on
the FMS-1650 is Setpoints Mode. The other two trigger modes will be
made available in a future firmware release.

Once Setpoints Mode is selected as the trigger mode for the relay
output, the user is prompted to select one of the four universal analog
inputs or one of the two dedicated thermistor inputs as the input
channel. While the default setting for the relay outputs is a one-to­one mapping, this selection allows the relay output to be remapped
to any one of the analog input resources. For example, if one of the
secondary relay outputs is to be used to control a strip heater in a
temperature control application, then that relay should be remapped to
the thermistor input that monitors the room temperature.

After selecting the input channel, clicking Next advances to the Relay
x High Setpoint entry screen, where the user may specify the threshold
above which the relay gets activated, or deactivated if in reverse acting
mode. After entering the high setpoint, clicking Next advances to the
Relay x Low Setpoint entry screen, where the user is prompted for
the threshold below which the relay gets deactivated, or activated if in
reverse acting mode.

If Occupancy Mode is selected as the trigger mode for the relay output,
the user is next prompted to select whether the relay output should
activated or deactivated for the two states of occupancy. Next, the
user is prompted for the acting mode and delay to be associated with
the relay output.

Figure 55. The action
mode and delay time
for secondary relays
may be configured at
this popup screen.

After specifying the high and low setpoints, the user is prompted for the
acting mode and delay associated with the relay output (Figure 55). In
direct acting mode, the relay output will be activated when the sensor
input exceeds the high setpoint, and will be deactivated when the
sensor input falls below the low setpoint.

In reverse acting mode, the relay output will be deactivated when the
sensor input exceeds the high setpoint, and will be activated when the
sensor input falls below the low setpoint. The relay output delay may
be up to 180 seconds, or three minutes, in duration.

If Isolation Mode is selected as the trigger mode for the relay output,
the user is next prompted to select whether the relay output should
activated or deactivated for each mode of isolation. Next, the user is
prompted for the acting mode and delay to be associated with the relay
output.

Configuring Universal Alarm Settings

The FMS-1650 incorporates an extremely flexible alarm facility that can
meet most any application requirements. The alarm system includes
both visual and audible alarms that may be independently enabled
for each monitored analog input in the system. There are two distinct
audible alarms to indicate higher and lower priority alarm conditions by
sound alone. An Alarm Quiet Period feature has been integrated in the
FMS-1650 which allows the audible alarms to be suppressed while still
allowing visual and networking alarms to continue.

All of the configuration settings associated with the FMS-1650 alarm
facility may be access at the Alarms Setup option on the second
page of the System Setup menus. Selecting this option invokes the
Alarms Setup menu as shown in Figure 58. Options on this menu
allow individual alarms to be enabled for each of the universal analog
inputs as well as the two thermistor inputs. Up to four (4) distinct alarm
setpoints may be configured for each analog input.

Enabling Individual Visual Alarms

Selecting the Enable Alarms option from the Alarms Setup menu

FMS-1650

Using Dual Sensor Mode

For applications that utilize the FMS-1650 as a room pressure monitor
or controller for a two adjacent spaces, the Dual Sensor Mode is the
optimum choice for the display mode setting. All dual sensor FMS­1650 units are preconfigured at the factory for this default display
mode, unless otherwise specified on the sales order.

This mode is typically used in applications where an isolation room
or patient room is separated from the main corridor or hallway by
an anteroom. Dual Sensor Mode allows each monitored space to
have independent isolation modes and separately controlled target
setpoints.

For example, an isolation room that is being controlled by a dual­sensor FMS-1650 may be configured for positive isolation with respect
to the adjacent anteroom, while the anteroom may be configured for
negative isolation with respect to the corridor or main hallway.

Dual Sensor Mode supports the display of the differential pressure of
the monitored room, the room temperature (if a temperature sensor
was ordered), the relative humidity of the room (if a humidity sensor
was ordered), and the air change rate associated with the monitored
room (if a flow sensor was ordered). Other information displayed on
the main screen in Dual Sensor Mode include the room name, the
current mode of isolation, the occupancy status, and the time and date.

To change the current mode of isolation for the room being monitored
and/or controlled, just touch the screen at the current isolation mode
to bring up the Set Isolation Mode configuration screen (Figure 24). If
at least one security password has been stored in the system, then
clicking on the current isolation mode will invoke the password entry
popup before allowing the user to change the mode of isolation. This
prevents the isolation mode from being inadvertently changed by
unauthorized personnel.

Changing the current displayed units for the room differential pressure
reading is as simple as clicking on the existing units (in WC or Pa),
which brings up a popup that provides convenient access to the
Engineering Units menu option on the Controller Settings menus
without having to go through the user menu system. The time and
date that are displayed at the bottom of the main screen may be set
simply by touching them individually and entering the new settings.

that may be selected which allows both differential pressure readings
to be displayed simultaneously at the main screen. To enable this
option, select Simultaneous View at the Dual View Mode configuration
screen that appears when dual sensor mode is selected. This results
in the main screen being divided exactly in half, with the upper half
displaying the primary differential pressure reading (AI-1) and the lower
half displaying the secondary differential pressure (AI-2). This is useful
for applications monitoring both an isolation room and its anteroom,
with the display mounted in the corridor outside of the anteroom.
The pressure reading along with the alarm status of both spaces is
continuously displayed at the main screen.

Using Triple Sensor Mode

For applications that require the use of three differential pressure
sensors, such as an anteroom with two common adjacent isolation
rooms, the Triple Sensor Mode is the optimum selection for the display
mode setting. All triple sensor FMS-1650 units are preconfigured at the
factory for this default display mode, unless otherwise specified at the
time ordering.

This mode is typically used in applications where two adjacent isolation
rooms share a common anteroom and the display is mounted outside
of the anteroom. Triple Sensor Mode allows two of the monitored
spaces to have independent isolation modes with separately controlled
target setpoints, and one monitored space with a fixed target setpoint.
In the example above, the two isolation rooms may be monitored by
AI-1 and AI-2, each with its own set of target setpoints and alarm limits,
and the anteroom monitored by AI-3 with its fixed target setpoint.
Triple Sensor Mode supports the display of all three differential
pressure readings simultaneously with the screen divided into
thirds. The upper third of the display indicates the primary (AI-1)
differential pressure reading, the middle third of the display indicates
the secondary (AI-2) differential pressure reading, and the lower third
section displays the differential pressure from the sensor connected to
AI-3.

This mode is typically used in applications where three adjacent
isolation rooms share a common anteroom and the display is mounted

controlled target setpoints, and two monitored spaces with fixed target
setpoints. In the example above, two of the isolation rooms may be
monitored by AI-1 and AI-2, each with its own set of target setpoints
and alarm limits, the third isolation room monitored by AI-3 with a fixed
positive or negative isolation setpoint, and the anteroom monitored by
AI-4 with its fixed target setpoint.

Quad Sensor Mode supports the display of all four differential pressure
readings simultaneously with the screen divided into quarters. The
upper quarter of the display indicates the primary (AI-1) differential
pressure reading, the second quarter of the display indicates the
secondary (AI-2) differential pressure reading, the third quarter of the
display indicates the third (AI-3) differential pressure reading, and

This popup includes an option for summing the input signals at two
analog inputs for the purpose of displaying a total air change rate on
the main display. If the application requires the air flow measurements
from two separate flow sensors to be summed to calculate total air
changes, the flow sensors must be connected to analog inputs 3 and

4.

Clicking Next at the air changes source popup invokes the Select
Source for Room Pressure Display configuration popup as shown in
Figure 83. This allows the user to specify which input should be used
for displaying the differential pressure reading on the main screen.

For example, if the FMS-1650 includes multiple pressure sensors
connected to the universal analog inputs, this configuration popup
allows the sensor that should be displayed on the main screen to be
selected. If the pressure is measured separate from the resources
attached to the FMS-1650, then that pressure value may be written to
the differential pressure network variable over the network.

The FMS-1650 incorporates four (4) writable network points that
support the displaying of sensor readings from other devices on the
same network. The four network writable points include differential
pressure, temperature, humidity, and air changes. To display any one
of these readings from a remote source, the Network Variable option
must be selected on the source selection configuration screen for that
particular reading.

Using Override Capabilities

The Overrides option on the Diagnostics menus provide a very useful
feature that allows the user to manually control the analog outputs and
relay outputs independently to assist with verifying the correct operation
and/or allocation of the controller resources. Selecting the Overrides
option on the Diagnostics menus invokes the Overrides menu as shown

feature that accomplishes this goal. Likewise, it may be necessary to
trigger one of the relay outputs to test the operation of the device to
which it is connected. One of the typical uses for the relay outputs
on the FMS-1650 is to trigger remote annuniciators to alert users of
an alarm condition at the controller. Being able to manually override
individual relay outputs allows this to easily perform this verification test.

Figure 97. Analog
outputs may be fixed
at the overridden level
indefinitely.

Selecting the Analog Outputs option on the Overrides menu allows the
user to choose one of the four analog outputs to override temporarily.
Selecting an analog output for override mode invokes the Override
Analog Output x configuration screen as shown below in Figure

97. The slider may be used to manually set the output to a specific
percentage. To lock the analog output temporarily at the overridden
level, the Lock Output option should be selected before clicking OK
to exit the override configuration screen. Any analog output that is
overridden and locked will remain fixed at the overridden level until
the output is subsequently unlocked. At the Override Analog Outputs
menu screen, any analog output that is currently locked at a specific
overridden level will be indicated by a yellow button instead of the
standard blue menu button.

During the installation process, oftentimes it becomes necessary to set
an analog output that is being used to control an air flow damper to a
specific percentage while manually adjusting the damper. The ability
to manually override individual analog outputs is an extremely useful

DIAGNOSTICS

Zero Calibrating the FMS-1650

FMS-1650

The FMS-1650 incorporates an extremely useful feature that allows
the unit’s zero reading to be calibrated after being installed. The Zero
Calibration and Reset Zero Offset options on the Diagnostics menus
provide the capability to reset the zero pressure reading for the specific
installation. Once the FMS-1650 has been completely installed,
including any peripheral remote sensor modules, this feature may be
used to recalibrate the unit’s zero reading so that it reads accurately
with the door to the monitored room left open.

With the door to the monitored room open, the differential pressure
measured by the FMS-1650 should approach zero. However, due
to imperfections in the sealing of the remote sensor enclosure and
pressure accumulation in the wall dividing the monitored room and the
adjacent corridor, the pressure reading may not actually reach zero. It
is not uncommon for the differential pressure reading to be as much as

0.0010 “WC with the door to the monitored room left open to allow the
pressure to equalize in the two spaces.

By selecting the Zero Calibration option on the Diagnostics menu,
this offset from zero may be completely eliminated so that the display
reads a true zero with the door open. Selecting this option invokes
the Zero Calibration input selection configuration screen as shown in
Figure 99, where the input to be zero calibrated should be selected.

Clicking the Next button after selecting the input to zero calibrate,
the message shown in Figure 98 is displayed indicating that air flow
through the sensor should be inhibited before proceeding with the zero
calibration procedure.

Leave the door to the monitored space open until the differential
pressure reading on the configuration screen stabilizes for at least 10
seconds. Once stabilized, click the Next button to perform the zero
calibration procedure to reset the zero reading. A popup window
appears indicating the status of the zero calibration process while
displaying the real-time differential pressure reading, which should
approach zero within a few seconds.

existing offset using the Reset Zero Offset option on the Diagnostics
menus. This option should be selected before repeating the zero
calibration procedure. Selecting this option invokes the Select Analog

TYPICAL APPLICATIONS FOR THE FMS-1650

Wiring & Confi guring External Devices

FMS-1650

Since the FMS-1650 integrates a full-featured controller with multiple
analog and digital I/O resources and an intuitive touch screen user
interface that can satisfy most application requirements, it is a very
effective solution for serving as a comprehensive room controller.

This section details the complete installation and configuration process
for using the FMS-1650 as a room pressure controller monitoring the
differential pressure in two separate spaces, ambient temperature,
relative humidity, and air change rate. This application utilizes all four
(4) universal analog inputs, one thermistor input, two analog outputs,
one digital input, and one relay output.

In addition to the FMS-1650 room pressure controller with internal and
remote sensors, the following components will be used to satisfy the
application requirements:

• Combination Temperature & Humidity Sensor, BAPI® part no.

BA/10K-2-H200-R

• Differential Pressure Transmitter, Ashcroft® part no. CX-4-MB2­10-1IWL

• Door Switch, Triatek part no. SWD200-2

• Remote Alarm Annunciator Panel

The hardware configuration dipswitch settings on the XMS1650 CPU
controller board should be set as follows:

• S1: positions 1, 3, 4, 5, 6, 8 OFF; positions 2 and 7 ON

• S3: position 5 OFF; positions 1, 2, 3, 4, 6, 7, 8 ON

• S4: positions 1 through 4 ON

Wiring

For this application of the FMS-1650, the wiring requirements are
relatively straightforward. The specific model number used as the
main room controller is Triatek’s stainless flush-mount room pressure
controller, part code FMS1650-F-1-1. This specific model is mounted
in a flush-mount enclosure, includes an internal sensor and one remote
sensor. Both sensors can accommodate differential pressures in the
±0.25” WC range and have an accuracy of ±0.5% FS.

The wiring diagram shown below in Figure 104 details the connections
from the sensors to the FMS-1650 backplane. Note that both the
BAPI® humidity sensor and Ashcroft® differential pressure transmitter
receive power from the FMS-1650 auxiliary power supply.

The step-by-step procedure for configuring the hardware resources of
the FMS-1650 room pressure controller for the application shown in
Figure 104 will be discussed in the next section.

Configuring Hardware Resources

The configuration of the FMS-1650 room pressure controller for the
application as shown below in Figure 104 involves setting up the
remote differential pressure sensor, temperature sensor, humidity
sensor, flow sensor (DP transmitter), and configuring the display
accordingly. While the internal differential pressure sensor has been
configured and calibrated at the factory and needs no adjustments,
the following procedure includes a confirmation of the internal sensor
configuration.

While the FMS-1650 is capable of serving as a stand-alone room
pressure controller, there are several added benefits that may be
achieved from connecting it to a network with other controllers. For
example, instead of using a remote alarm annunciator panel to alert
personnel of an alarm condition at the monitored room, Triatek’s
Central Monitoring Station (CMS-1650) may be used to remotely
monitor up to four (4) individual FMS-1650 room pressure controllers.
For more information on this product, please refer to the datasheet for
the CMS-1650 Central Monitoring Station.

dampers in the two spaces. The primary space, the isolation room, will
be maintained at a positive differential pressure of 0.0100 “WC while in
positive isolation mode.

The secondary space, the anteroom adjacent to the isolation room,
will be maintained at a negative differential pressure of -0.0100 “WC
while in negative isolation mode. Analog output AO-1 will control the
damper in the isolation room, while AO-2 will control the damper in
the anteroom. Both analog outputs will operate in closed-loop or PID
control mode, and will output a 2 to 10 Vdc signal to the damper being
controlled.

PID TUTORIAL

PID Tutorial

PID is an acronym that stands for Proportional-Integral-Derivative, and
is a generic closed-loop control mechanism that is commonly used in
many industrial control systems. It is by far the most commonly used
feedback controller in use today. A controller which implements PID
mode continuously calculates the difference (or error signal) between
a measured process variable (PV) and a desired setpoint (SP). The
PID controller attempts to minimize this error by adjusting the process
control inputs, also referred to as the manipulated variable (MV). A
block diagram of a PID controller is shown in Figure 106.

Figure 106. Block
diagram of a PID
controller.

The PID controller algorithm consists of three parameters: proportional,
integral, and derivative. In terms of time, the proportional term
depends on the present error, the integral term depends on the
accumulation of past errors, and the derivative term is a prediction
of future errors. The weighted sum of these three terms is used to
adjust the process via a control variable such as the position of a
control valve of the power applied to a heating element. In the case
of applications for the FMS-1650 as a room pressure controller, the
process variable is the differential pressure and the control variable is
typically the position of an exhaust damper.

and cold valves of a faucet are adjusted to maintain the water from the
faucet at a desired temperature. This involves the mixing of the two
process streams, the hot and cold water. Touching the water allows
the temperature to be sensed or “measured.” Based on this feedback
of sensing the water temperature, a control action may be performed
to adjust the hot and cold water valves until the process temperature
stabilizes at the desired value.

Sensing the water temperature is analogous to taking a measurement
of the process variable (PV), while the desired temperature is referred
to as the setpoint (SP). The input to the process (water valve position)
is referred to as the manipulated variable (MV). The difference
between the “measured” temperature and the setpoint is the error (e)
and quantifies whether the water is too hot or too cold, and by how
much. After measuring the temperature (PV), and then calculating
the error, the controller decides when to change the tap position (MV)
and by how much. When the controller first turns the valve on, it may
turn the hot valve only slightly if warm water is desired, or it may open
the valve all the way if very hot water is desired. This is an example
of a simple proportional control. In the event that hot water does
not arrive quickly, the controller may try to speed-up the process by
opening up the hot water valve more as time goes by. This is an
example of an integral control.

PID Controller Theory

The PID closed-loop control scheme is named after its three correcting
terms, whose sum constitutes the manipulated variable (MV):

By tuning the PID parameters or constants in the algorithm, the
controller can provide control action designed for specific process
requirements. The response of the controller can be described in
terms of the responsiveness of the controller to an error, the degree
to which the controller overshoots the setpoint, and the degree of
system oscillation. Some applications may require using only one or
two terms to provide the appropriate system control. This is achieved
by setting the constant(s) of the undesired control output(s) to zero.
The variations include PI, PD, P, or I controllers in the absence of the
respective control actions. PI controllers are relatively common, since
the derivative term is sensitive to measurement noise, whereas the
absence of an integral value may prevent the system from reaching its
target value due to the control action.

A typical example of a closed-loop control scheme is when the hot

Proportional Term

The proportional term (sometimes referred to as gain) makes a change
to the output that is proportional to the current error value. The
proportional response can be adjusted by multiplying the error by a
constant K

called the proportional gain. The proportional term of the

p

output is given by:

K

: proportional constant (tuning parameter)

p

SP: setpoint or desired value

PID TUTORIAL

PID Tutorial

FMS-1650

PV: process variable or measured value
e: error = SP – PV
t: time or instantaneous time (the present)

A high proportional gain results in a large change in the output for
a given change in the error. If the proportional gain is too high, the
system may become unstable. In contrast, a small gain results in a
small output response to a large input error, and a less responsive (i.e,
slower) controller. If the proportional gain is too low, the control action
may be too small when responding to system disturbances. For most
closed-loop control schemes, the proportional gain should contribute
the bulk of the output change.

Integral Term

The integral term (sometimes referred to as reset) is proportional to
both the magnitude of the error and the duration of the error. Summing
the instantaneous error over time (integrating the error) gives the
accumulated offset that should have been corrected previously. The
accumulated error is then multiplied by the integral gain and added to
the controller output. The magnitude of the contribution of the integral
term to the overall control action is determined by the integral gain, K

.

i

The integral term is given by:

where:
K

: integral constant (tuning parameter)

i

SP: setpoint or desired value
PV: process variable or measured value
e: error = SP – PV
t: time or instantaneous time (the present)

: dummy integration variable

The integral term, when added to the proportional term calculated
above, accelerates the movement of the process towards setpoint
and eliminates the residual steady-state error that occurs with a
proportional-only control scheme. However, since the integral term
is responding to accumulated errors from the past, it can cause the
present value to overshoot the setpoint value (cross over the setpoint
and then create a deviation in the other direction).

Derivative Term

The rate of change of the process error is calculated by determining
the slope of the error over time (i.e., its first derivative with respect to
time) and multiplying this rate of change by the derivative gain K

. The

d

magnitude of the contribution of the derivative term (sometimes called
rate) to the overall control action is termed the derivative gain, K

.

d

The derivative term is given by:

where:
K

: derivative constant (tuning parameter)

d

SP: setpoint or desired value
PV: process variable or measured value
e: error = SP – PV
t: time or instantaneous time (the present)

The derivative term slows the rate of change of the controller output
and this effect is most noticeable close to the controller setpoint.
Hence, derivative control is used to reduce the magnitude of the
overshoot produced by the integral component and improve the
combined controller-process stability. However, the differentiation of
a signal amplifies noise and thus this term in the controller is highly
sensitive to noise in the error term, and can cause a process to
become unstable if the noise and the derivative gain are sufficiently
large.

The proportional, integral, and derivative terms are summed to
calculate the output of the PID controller. Defining u(t) as the controller
output, the final form of the PID algorithm is:

where the tuning parameters are:

Proportional gain, K

p

Larger values typically mean faster response since the
larger the error, the larger the proportional term compensation. An
excessively large proportional gain will lead to process instability and
oscillation.

Integral gain, K

i

Larger values imply steady-state errors are eliminated more
quickly. The trade-off is larger overshoot: any negative error integrated
during transient response must be integrated away by positive error
before reaching steady-state.

Derivative gain, K

d

Larger values decrease overshoot, but slow down transient
response and may lead to instability due to signal noise amplification in
the differentiation of the error.
