WIRING & SETUP
RS-485 Controller Network
Wiring & Setup
All controls connected to the network must be pro-
grammed using the same communication baud rate (9600
baud rate is recommended) as well as a unique communi-
cation address from 0 to 255, excluding 248. On controllers
with displays, this is accomplished using the keypad and
display, or using TCS Insight software, or by calling TCS
Technical Support. TCS Technical Support can access the
QWL 3.1 Rev 3 Series Panel online and change the address
of a controller.
Use 22 AWG, twisted shielded 3-conductor cable for net-
work wiring. Network wiring should start at one controller
and go to the next and then go to the next, and so on until
the final controller is reached. Wiring is such that all “A”
wires are connected to “A” wires, all “B” wires are connect-
ed to “B” wires, and all “REF” wires are connected to “REF”
wires.
A 120 Ω terminating resistor should be placed at each of
the two ends of the network directly across the “A” and
“B” wires. If the QWL 3.1 Rev 3 Series Panel will be at one
end of the network, hard wire a 120 Ω terminating resis-
tor across the “A” and “B” terminals at the QWL 3.1 Rev 3
Series Panel (See 1 below).
If the QWL 3.1 Rev 3 Series Panel will be in the middle of
the network, do not wire in the terminating resistor on the
QWL 3.1 Rev 3 Series Panel terminal block (See 2 below).
Finally, connect one end (ideally the furthest end from

CONFIGURATION
the QWL 3.1 Rev 3 Series Panel) of the shield wire of the
network wiring to earth ground. TCS recommends a 250
milliseconds time out period for all wired networks, and
1000 milliseconds for wireless networks. If you encounter
timeout errors please contact TCS Technical Support.
NOTE: In the middle of the network, all network wiring
shields should be twisted together and taped off to prevent
accidental grounding. More than one ground on the shield
wiring can result in communication failure.
NOTE: A maximum of two (2) terminating resistors can be
used. See below.
Gateway Configuration Page
After connecting and logging in, the operation of the unit
can be configured by selecting the proper parameters for
your application. All Ubiquity Cloud Application software
and functionality is accessed by logging into the central
server (www.ubiquitysystems.net) not by using this config-
uration page.
INSTALLATION INFORMATION
This section contains installer and site related information.
The information entered here is sent to the central server
when a site initially comes online to help identify the site
to link it to the correct Ubiquity Cloud site. For the most
part, this information is for reference purposes only, except
for the Site Time. The Site Time is used by the local net-
work and the QWL 3.1 Rev 3 Series Panel until the Ubiquity
Cloud central server performs a time synchronization with
the site.
Once you are finished entering information in this section,
click the Update Installation Info button.
RS-485 Network - Port Configuration: Configure each of
the detected COM ports for this site. Typically,
you will leave Auto Detection of Controls on All Ports
enabled so the QWL 3.1 Rev 3 Series Panel will find and add
controllers as they are found. If auto-detection is disabled,
new controllers must be added manually in Ubiquity Cloud.
The communication ports are automatically detected once
the QWL 3.1 Rev 3 Series Panel is powered up. Once detect-
ed each COM port needs to be configured to ensure proper
functioning of the network on each port. Each port can be
enabled or disabled from the drop down menu.
Select the proper protocol being used on each port. The
current protocol selections from the drop down menu are
TCSbus or Modbus. Select the communication baud rate
for each port. This setting must be the same as all of the
controllers on that port. Adjust the Time-Out Period for
each port. 250ms for wired networks and 1000ms for all
wireless networks is recommended. The default baud rate
is 9600 baud and is recommended.
APPLICATION INFORMATION
This section contains settings which define how the QWL
3.1 Rev 3 Series Panel interacts with the controller network,
and how it communicates the data to the actual server.
Application Options: Select a Controller Network Poll-
ing Cycle time for the QWL 3.1 Rev 3 Series Panel. This is
the time interval that the unit will poll the entire network
of controllers on all ports. The default setting is one (1)
minute. Select whether to allow caching the host name via
DNS. Typically, this is left unchecked. Select how often the
QWL 3.1 Rev 3 Series Panel connects to the central server.
Typically this is set to “Always On.”

CONFIGURATION & COMMISSIONING
COMMUNICATION INFORMATION
This section contains settings which control how the QWL
3.1 Rev 3 Series Panel connects out through the LAN or
WAN to the Internet. All of these settings are determined
by the local network administrator or IT department. The
correct settings, network permissions, and port openings
(ports 80 and/or 443) need to be verified prior to installa-
tion and connecting to the local network.
Communications Options: The QWL 3.1 Rev 3 Series Pan-
el supports both static IP and Dynamic Host Configuration
Protocol (DHCP) IP address allocations. Enter the central
server Location, typically www.ubiquitysystems.net by click-
ing the “Set Ubiquity Domain Name” button. There are a few
special options which can be enabled: TCP window scaling,
IPV6 and Secure Sockets Layer (SSL requires port 443 to
be open), select whether to enable or disable these special
options. Enter host name if needed (typically left blank).
Network: Select the desired IP allocation (DHCP or static
IP addressing) to be used. When using static IP, it is neces-
sary to enter the IP Address, Gateway, Subnet, DNS1 and
DNS2 settings Virtual IP can be used (typically left blank).
The IP settings will need to be established by the LAN/WAN
network administrator prior to installation. When utilizing
DHCP addressing, the IP address settings are automatically
assigned when communication is established.
Proxy: If a proxy is required, select Static Proxy from the
drop-downy and enter all the related details in the fields
that appear. Once you are finished entering information in
this section, click the Update Commissioning Info button.
SECURITY INFORMATION
This section contains settings which control the security
of the gateway within the QWL 3.1 Rev 3 Series Panel and
whether or not it can be accessed through the web inter-
face. Enabling Secure Mode disables all web interfaces
including the configuration page, and requires a specially
configured USB flash drive or TCS Technical Support ac-
cess to the QWL Panel if it is online with the Ubiquity Cloud
central server to “unlock” it.
Here is where you change the default login credentials
used to access the Configuration Page. It is recommend to
change these login credentials.
Once you are finished entering information in this section,
click the Update Security Info button.
Commissioning Tools
A separate page which contains various commissioning
tools can be accessed by clicking the “Commissioning
Tools” button at the bottom of the Setup page. This page
gives you access to additional information about the con-
nection status of the QWL 3.1 Rev 3 Series Panel and the
controller network connected to it.
UBIQUITY CLOUD CONNECTION STATUS
This section displays the status of the connection between
the QWL 3.1 Rev 3 Series Panel and the central server. You
have 3 options for the message that will appear here:
1) Error - No Route to Host -- means the unit does not cur-
rently have an Ethernet connection.
2) Connected -- means the unit is able to communicate to
the Ubiquity Cloud central server BUT is not being matched
up with a specific Site, typically this indicates that the site
is not initialized on the central server side yet, please con-
tact TCS Basys Controls to assign or initialize the QWL 3.1
Rev 3 Series Panel to a site.
3) Established -- means the unit is communicating with
the Ubiquity Cloud central server AND is ready to go. All
Ubiquity Cloud functions (monitoring, programming, alarm-
ing, etc.) should be available through the user interface at
this point.

COMISSIONING & PROGRAMMING
Clicking the green button with the arrow on it on the right
side of the Ubiquity Cloud Connection Status title bar will
refresh the connection status.
CONTROLLER VIEW
This section allows you to see what controllers have been
found by the QWL Panel and view each controller’s address,
model, and communication status. The state field will show
AUTO-DETECTED initially when found by the unit and CON-
FIRMED once the controller has been recognized by the
Ubiquity Cloud central server. This information allows the
installer to verify that each controller has been found by the
QWL Panel and is communicating with the local network.
Clicking the green button with the arrow on it on the right
side of the Controller View title bar will refresh each con-
troller’s status.
SYSTEM COMMANDS
In this section you are able to set a couple of system flags
for the QWL 3.1 Rev 3 Series Panel itself. “Reboot Unit”
sets a flag which will shut off and restart the QWL 3.1 Rev
3 Series Panel within a 5 minute Cycle. “Check for Update”
contacts the Ubiquity Cloud central server for any updates
relevant to its particular model number and software ver-
sion. Once the update has been downloaded, it is automati-
cally applied, and the unit may reboot.
NOTE: The “Check for Update” command requires that the
QWL 3.1 Rev 3 Series Panel has Internet access to retrieve
the update patch.
Programming - Lighting Module
The lighting module portion of this panel is an SLQ218. It
must be programed using TCS Insight or Ubiquity Cloud.
CHANNEL EVENT SCHEDULING
There are eight independent channels each with its own
schedule. If the occupied or “ON” time for a particular day
is from 8:00AM to 5:00PM. In the schedule enter 8:00 to
17:00. Within the Ubiquity Cloud programming page, the
desired schedule is simply selected from the drop-down
menu for each channel. If the desired schedule is not
shown in the drop-down, new schedules can be created or
existing schedules can be edited on the Scheduling page.
CHANNEL HOLIDAY SETUP
Holidays are created as part of the Scheduling page and
will appear as part of the selected schedule. You can cre-
ate date specific holidays, roaming holidays, or select from
a list of standard bank holidays. If the selected schedule
does not include the desired holiday(s), the schedule can
be edited on the Scheduling page.
ENABLE BLINK OUTPUT
The Blink Output option forces the respective lighting out-
put turn off four times, five minutes prior to an unoccupied
or off period. This will give an indication that a scheduled
on time is about to end. Click the checkbox to enable this
function for each channel.
ENABLE ASTRONOMICAL TIME
The Astronomical Time option allows the controller to turn
a channel off based on the locations sunrise and sunset
times. See the Astronomical Time section later in the man-
ual for more details and additional configuration options.
Click the checkbox to enable this function for each chan-
nel.
WHEN CHANNEL IS “ON”
You can select how you want the time clock output (Digital
Output Mode) to behave when the channel is occupied or
“ON”. You can choose for the Relay to be Normally Open
or Normally Closed during on periods. Simply select the
desired behavior form the drop-down menu.

COMISSIONING & PROGRAMMING
AI1 AMBIENT LIGHT INPUT
If using an ambient light sensor (0 to 5 or 1 to 5V); set the
low and high scaling limits for AI2. These limits are what
the light sensor reads at low limit and what the light sensor
reads at full scale.
A Lighting Channel Threshold and Hysteresis for each of
the available channels can be set for this input signal. The
Channel Power Threshold is basically a setpoint for which
AI1 is compared to determined when to turn off the select-
ed cycle(s). The Channel Power Hysteresis is a buffer value
which is prevents the channel from cycling off/on prema-
turely. For example, if the input is scaled 0 to 1000 lumens
and you want to turn off one channel if the input gets up to
500 lumens and allow it to come back on if the input falls
to 400 lumens, enter in 0 for the scaling low limit, 1000 for
the scaling high limit, 500 for the threshold and 10% for the
hysteresis for that channel.
Select a threshold and hysteresis for the channels which
will be allowed to be shut off based on this input hitting the
threshold. A common application for this feature is to con-
trol parking and exterior signage lighting. Essentially the
channel will be on all the time it is occupied except when
there is too much light. (Similar to the astronomical time
function). If AI1 is not used, the threshold for all channels
MUST equal the scaling high limit.
AI2 ENERGY / POWER / MONITORING INPUT
If using an energy meter, power meter or current trans-
ducer (0-5V), set the low and high scaling limits for AI2.
These limits are what the energy or power meter reads at
0V and what the energy or power meter reads at 5V. For a
4 to 20mA input to be wired to AI2, a 250 Ω resistor must
be installed between AI2 and GND. If you want to use this
input with a threshold and hysteresis (Channel Power
section) to shut off lighting channels, select the relevant
lighting channels (Enable AI2 Threshold checkboxes) and
enter a threshold and a hysteresis to be used. If AI1 is not
used, the channel power threshold MUST equal the scaling
high limit.
Select whether you want the time clock output (Digital
Output Mode) to be Normally Open or Normally Closed dur-
ing on periods.
The Channel Power Threshold is basically a setpoint to
which AI2 is compared to determine when to turn off the
selected channel(s). The Channel Power Hysteresis is a
buffer value which prevents the channel from cycling off/
on prematurely. For example, if the AI2 input is scaled 0 to
10000 KW and you want to turn off some channels if the
input gets to 7500 KW and allow them to come back on
if the input falls to 6500 KW, enter in 0 for the scaling low
limit, 10000 for the scaling high limit, 7500 for the thresh-
old and 10% for the hysteresis. You should choose this
threshold to be larger than the accuracy/error specification
of the equipment/device being turned off so it does not
cycle on and off.
AI2 AMBIENT LIGHT INPUT
If AI2 is not used for power limiting, a second light sensor
can be used to monitor another area. Set the low and high
limits for AI2. These limits are the light sensor reading at
0Vand the sensor reading at 5V respectively. Click on the
Enable box for each of the channels to be controlled by
AI2 (in the Enable AI2 as Light Level Source column). Then
proceed to enter threshold and hysteresis values for each
channel (located just below the AI1 AMBIENT LIGHT INPUT
section). Each channel that is selected/checked (Enable
AI2 as Light Level Source) will then have its threshold/hys-
teresis compared to AI2 instead of AI1.
CHANNEL MONITORING AND CONTROL
DI1 and Override 1 are used for Channel 1, DI2 and Override
2 are used for Channel 2, etc.
There are four Digital Input Modes which can be used with
a digital input: Regular, External Override, Momentary Over-
ride, & Monitor.
Regular mode: The digital input is used in conjunction with
the programmed schedule in determining when the relay
output should be on or off.
External Override mode: The digital input acts the same as
the override button on the front of the QWL 3.1 Rev 3 Series

COMISSIONING & PROGRAMMING
Panel. The switch used for this type of digital input must be
a momentary N.O. switch.
Momentary Override: The digital input acts like a toggle
switch. This must also be a momentary N.O. switch. If the
time clock is on, pressing the switch turns it off, If the time
clock is off, pressing the switch turns it on.
Monitor mode: the digital input acts as a monitor for the DI
and has no other function.
ASTRONOMICAL TIME
The Astronomical time function may be setup on any of
the channels. It controls and turns off the enabled light
channel for the daylight period form sunrise to sunset. The
following diagram illustrates the typical application of this
capability.
DIGITAL INPUT DELAY/FILTER
Enable the Digital Input Delay if you want the Digital Input to
be present for 15 seconds before it takes effect. This can
prevent cycling. Note, this delay if selected, will apply to all
eight channels.
To setup astronomical time, enter the Latitude and Lon-
gitude parameters for the location being controlled. Also
enter the time offset from GMT (Greenwich Mean Time).
For example, the USA Central Standard time zone is offset
-360 minutes from GMT. Madison, Wisconsin, USA is at 43°
5 minutes North (+) Latitude and 98° 30 minutes west (+)
Longitude. The GMT Offset range is + 720 Minutes. Also
click the box if applying daylight savings time to the astro-
nomical time calculation.
Next, select the channel(s) that should have the astronom-
ical time function and click the Enable box. This is done in
the Schedule section of the page.
Note: For non-North American Daylight Saving time set the
manual DLS (Day Light Saving) time.
CHANNEL OCCUPANT OVERRIDE
This is the number of minutes from 0 to 255 (4 hr, 15 min)
which the controller will bring a system that is Off to On
when its override button is pressed. This time can be differ-
ent for each channel.
Occupied Override: Select whether to allow an occupied
override and if so, whether it will be a schedule or channel
override.
HOLIDAY VANISHING
Choose whether to enable the Holiday Vanishing Feature. If
checked, the controller will make the number of days for a
holiday 0 after the holiday is over. This will keep the holi day
from occurring in subsequent years if it is not reprogrammed.
POWER DOWN PERIOD
If the controller loses power, it can remember which chan-
nels have been overridden and how much time is remaining
in each override period. This is the amount of continuous
power loss time in minutes where the controller will re-
member the override status’. If the controller loses power
for longer than this period, the override buttons will have to
be pressed again as necessary.
INPUT VOLTAGE
The input voltage is monitored. The calibration factor is
used to scale the controller’s 24 VAC power input to the
appropriate line voltage. For example, if the line voltage is
120 VAC and the SLQ218 power input is 24 VAC, then the
calibration factor is 5.0. If the line voltage is 120 VAC and
the controller power input is 27 VAC, then the calibration

COMISSIONING & PROGRAMMING
factor is 4.4 If the line voltage is 277 VAC and the SLQ218
power input is 24 VAC, then the calibration factor is 11.5.
DAYLIGHT SAVING TIME
If Daylight saving is used, simply enable the “Daylight Sav-
ing Time” option within the software and enter the starting
month + week and the ending month + week.
Programming - Pulse Meter
The utility pulse meter module portion of this panel is an
SEQ100.
METER INPUTS
There are four meter inputs available. Each one is setup for
a dry contact and cannot be changed. Each input (Meter 1,
Meter 2, Meter 3 & Meter 4) can be configured to accept
signals representing electrical, BTU, water or gas usage.
The required parameters will be provided by either the
utility company involved or on the current transducer (CT)
used to generate the pulse signal.
METER TYPES
The SEQ100 supports various meter types. Selecting a
meter type changes the default values as they are used to
calculate meter consumption and demand for that particu-
lar meter. For each of the four SEQ100 meter inputs, there
are five selectable options:
ELEC 1 PH: Electric single phase meter.
ELEC 3 PH: Electric three phase meter.
GAS: Gas meter.
WATER: Water meter
BTU: BTU meter
Utility pulse meters can be one of two different types,
depending on whether they count the leading and trailing
edges of the pulse or only the leading edge of the pulse as
If you have a Type C device (3 terminals KYZ), you will
need to double the multiplier. The SEQ100 only counts the
contact closures for the K and Z terminals. Doubling the
multiplier will correct this problem.
PROGRAMMING THE METER CONSTANTS:
CT Value: The value of the CT wired to the meter. This
value is usually provided on the CT or on the utility output
meter. This value is only used for and electric meter.
P/REV: The Pulses per revolution for the meter. This value
is usually provided from the utility company.
CONSTANT: The value of the constant for the meter is usu-
ally provided from the utility company and many times is
located on the electric or gas bill.
CU FT/P: The value for Cubic Feet per pulse. This only
applies to Water, GAS and BTU, and is usually found on the
utility meter itself.
MULT: The multiplier for the meter can be used to scale
the meter output or correct for KYZ meter. The multiplier
is used to convert the pulses to engineering unit data. For
example, if your meter provides one pulse per 0.01KWH,
then a constant of 0.01 is required.
MULTIPLIER:
Each model of power meter is different and has a different
multiplier. For example, if the meter is a Type A and reports
1/10 kWh per pulse, set the input multiplier to 0.1. If the
meter is a Type C and reports 1/10 kWh per pulse, set the
input multiplier to 0.2.
a single count. A pulse output can be either a mechanical
relay or solid state device. The pulse output corresponds
to a unit/time of a monitored quantity. The amount of time
between states of a pulse output corresponds to the meter
demand and the number of pulses is proportional to the
meter’s consumption.
Below is a diagram depicting two types of utility meter
pulse outputs. Meter Type A counts only the leading
edge as a single pulse and the trailing edge is ignored.
Meter Type C is known as a true KYZ meter and counts
both the leading and trailing edges as a pulse, effectively
doubling the number of pulses as seen by Meter Type A.
The SEQ100 measures Type A output only; however, KYZ
functionality can be mimicked by using a “Meter Multiplier”
value of 2.
In the following picture, both Type A and C are shown.
Three pulses are shown, labelled 1, 2, and 3. Notice how
the Type A output closes and opens for each pulse, where
the Type C output simply changes state.

POWER: This LED indicated that the QWL 3.1 Rev 3
Series Panel has power applied
• The reset button in the lower right hand corner is used
to “reboot” the entire QWL 3.1 Rev 3 Series Panel. This
is accomplished by pushing and holding the button for
5-7 seconds.
Note: During a reboot, the lights associated with the
Lighting Module of this product could go out, it is
recommended that you open the panel and place the Hand-
Off-Auto switch for the corresponding channel in the Hand
position to ensure that the lights that should be on remain
on.
CPU: This LED indicates that the CPU or QD2040 portion of
the panel is active and running.
Checkout & Troubleshooting
QWL 3 .X Series Panel
• Be sure to check and verify all wiring before
powering up the QWL 3.1 Rev 3 Series Panel
• The QWL 3.1 Rev 3 Series Panel is designed to
contain 24 VAC devices and wiring ONLY. No line
voltage (120 VAC or greater) is to be installed
within this panel.
• If you created metal shavings, ensure they are
cleaned up and not in a position to allow for
shorting before powering up.
Lighting Module - SLQ218
• Verify all wiring before powering up the QWL 3.1
Rev 3 Series Panel and the SLQ218.
• Place the Hand-Off-Auto switches in the off position
You must obtain the correct pulse multiplier from the
meter manufacturer prior to configuring the SEQ100.
Some power meters have an option to configure the multi-
plier. Options often include 1, 0.1, 0.01, kWh per pulse. The
best method to configure the pulse is to select the small-
est multiplier available, considering the maximum load and
pulse rate. To calculate the pulse rate, use the following
formula:
In general, the SEQ100 calculates electric meter consump-
tion and demand as follows:
Pulses
= KW*3600*multiplier
Second
The diagram above depicts how a single pulse and the
pulse time difference are represented on a pulse waveform
input into the SEQ100.
TCS ZigBee Wireless Network
The QWL 3.2 includes a QW1010 TCS ZigBee wireless
gateway to manage the TCS ZigBee wireless network.
Be sure to plug the USB cable into one of the QWL 3.2
USB ports and configure it for the TCS protocol before
initiating the wireless controllers. The QW1010 will also
need to be properly setup before the wireless network
will communicate (Please refer to the QW1010 Product
Manual).
Demand =
(CTValue*MtrConst*MtrMult)
(PPRValue*PulseTimeDiff)
Consumption =
(PulseCount*CTValue*MtrConst*MtrMult)
(PPRValue*PulseTimeDiff)

CHECKOUT & TROUBLESHOOTING
• Place the appropriate (Normally Open) NO or
(Normally Closed) NC jumpers (both included) in
position-RED wires = NO-ON=Closed and BLACK
wires=NC-On=Open
Utility Meter Pulse Transducer Module - SEQ100
• Verify all wiring prior to powering the QWL 3.1 Rev
3 Series Panel and SEQ100.
• Take note of the current readings for all meters.
Since the SEQ100 is used for only monitoring, and
is the reading appear to be correct, you are done.
• If a value does not appears to be correct, verify on
the programming page the value programmed in is
correct.
• If a value is shown as 0 (Zero) the SEQ100 is not
receiving a pulse signal.
Site Communications Center - QD2040
• Be sure to verify all wiring and programming
information before hooking up to Network
• If the CPU LED does not light up, verify that the
power supply nodule (included with the QWL 3.1
Rev 3 Series Panel) is plugged in to an outlet that
has power.
IF THEN
Check that the baud rate set on the controller(s) are all
set the same. Verify controller address.
Rx LED is always on. This is typically a problem with
wiring.
Check wiring. Make sure that communication wiring
runs are at least 5' away from fluorescent lights, motors,
etc. Make sure that all controllers on a network have a
unique address.
Make sure that the "A" and "B" wires are not switched or
shorted. Make sure that there is no stray voltage on the
"A" and "B" wires. "B" to "A" should measure between
0.5 VDC and 3.6 VDC. "B" to "A" should measure 0
VAC. "A" to "Shield" and "B" to "Shield" should measure
0 VAC and 0 VDC.
Both Tx and Rx LEDs will blink. Both the computer and
the controller are responding, but you still receive com-
munication errors.
Tx LED blinks, Rx LED is always off. If this happens,
the computer is sending, but the controller is not
responding.
On smaller networks, try removing one of the two
terminating resistors.
