Chapter 2: Site Survey and Connectivity Test
By powering the RTU and testing connectivity before mounting the hardware, you
can optimize the signal strength for years of trouble free communications. The
test only takes a few minutes since the included battery can provide temporary
power.
1. Remove the RTU from the box and place it on or near the control panel it will
be monitoring.
2. Remove the antenna cable and antenna whip from the package and hand
tighten the SMA-M connector into the RTU’s radio SMA-F connection. See
Figure 1. DO NOT OVER TIGHTEN.
3. Screw the whip antenna onto its base and then temporarily get it as high as
possible outdoors. DO NOT SET IT ON THE GROUND.
4. Power the RTU with the 12 VDC battery (see Figure 1). Connect the negative
(black) lead to the battery rst and then connect the positive (red) lead. You
should then see the vertical status LEDs on the lower right corner of the main
board light up in an up and down pattern and then the horizontal digital LEDs
above the digital inputs will scroll side to side, then all go out. (See Figure 1
for LEDs).
5. Next, you should see a single solid green LED light up on the top of the
vertical status LED stack on the lower right corner of the main board and the
radio status red LED on the lower left corner of the radio light up solid. As the
green LED on the vertical stack descends downward, the radio status red LED
should start blinking. Once the LED on the vertical stack reaches the bottom
BAT LED, the green carrier LED should come on and you should hear 3
beeps from the buzzer. This indicates the unit has connected and is online.
When the RTU is online the green carrier LED will remain on and the red radio
status LED will continuously ash. The Top “A” LED on the vertical status LED
indicator should be on after the unit transmits its rst transmission and the
“DAL” LED should be ashing rapidly. The “TRB” LED will be on due to no AC
connection to the main board.

If the sequence of events does not occur after two attempts, refer to Chapter
8: Troubleshooting or call technical support.

Chapter 3: RTU Installation and Wiring Overview
Turn off station power when running wires
to the RTU.
Locate the RTU as close as possible
to the control cabinet while taking into
consideration the antenna cable length.
Flatpaks mount inside of the control
cabinets. The NEMA 1 enclosures mount
on internal walls of buildings. NEMA 4
enclosures mount outdoor on a strut rail.
1. Cut the conduit and wiring holes. Drill
Nema 4 mounted on strut rails
and pull the conduit holes in the control
cabinet and Mission RTU (NEMA 4 or
NEMA 1). Flatpaks have 2 large holes in
the back plate to drill through the cabinet
inner door and provide wire access. If
you have a Flatpak enclosure, mount
the antenna on top of the control cabinet
or other structure nearby. You can also
mount a pole if necessary. Use sealant
Nema 1 mounted on a wall
if desired around the
outer edge if on top of
the control panel.
2. Pull the wires and
cables. Verify that
station power is off.
Before nal connection
of ex conduit, rst pull
the wet well cable (if
used), then the AC and
input wires. Lay wires
Nema 4 Flatpak
in wire trays with excess near terminations. Replace wire race covers. Ensure
loose wires are NOT touching any other equipment.
11
CAUTION: To avoid analog spikes, place an MOV suppressor directly
across the contactor coils for all of your high load devices. Next, make
sure all cables used for digital and analog inputs are shielded, twisted pair
wire with the shield connected to ground on the Mission side of the cable
and NOT connected on the far end of the cable (to prevent ground loop
current). Finally, avoid running the Mission analog and digital cable in the
same conduit with 120 VAC cables, especially high current cable. Make
sure to dress the Mission signal cables so they do not run parallel to AC or
high current cabling.
3. Connect digital inputs. Verify that power is still off. Mission’s default input
connections are as follows: Inputs 1, 2, and 3 are pump runtime accumulators;
Input 4 is high wet well, Inputs 5 and 6 are pump 1 fail and pump 2 fail, Input
7 is phase fail and 8 is unassigned. Refer to the wiring diagram on the M110/
M800 cover/door and RTU Installation Form in the packing box. Record input
names on the setup form and the diagram. The inputs are normally open
by default. You may use normally closed contacts on inputs 4 through 8.
However, you must tell Mission Technical Support on the unit set up form or
via the telephone. You MUST use normally open contacts on pump runtime
inputs. Refer to the typical wiring for monitoring a standard trouble relay insert
in the back of this manual.
CAUTION: Digital inputs are dry contacts. This means that wires running
to these inputs must not have any voltage supplied. This is the number
one installation mistake. Do not use a common input wire.
Wire supervision: The main board inputs require the use of a 1000 ohm endof-line resistor for each digital input used for alarm/event reporting. These
resistors are connected to and placed in parallel with the monitored relay
contacts and allow the main board circuitry to monitor the integrity of the
connections. See Figure 2 for installation. If you cannot easily install the
resistors at the relay, you can install them across the digital input you are
using for that alarm. By doing that, you will not have line supervision.
Pump Runtime Inputs: Inputs 1, 2 and 3 are pre-programmed at our facility
for pump runtime inputs. If you only use inputs 1 and 2 or you are monitoring
just alarms, inputs 1, 2 and 3 can be set to alarm inputs. Call Mission for
12
assistance. For M110 RTUs: If you are only using inputs 1 and 2 for pump
runtimes and you are NOT using input 3 for anything, you can leave the
resistor out of input 3 (only this input) and this will then allow you to get
simultaneous runtimes of pumps 1 and 2. The data will populate under
runtime data on the customer website. Otherwise, install the resistor in the
unused input.
Pump runtime inputs should be wired to the normally open contacts of the
runtime relays. Alarm relays can be wired either normally open or normally
closed. (If ordered and using a Wet Well Module, follow its runtime connection
instructions).
4. Ground the RTU. Use 8-10 gauge green wire installed to the Mission back
plate screw of the RTU or 1 of the 4 screws holding the main board on to the
back plate (refer to Figure 2). Do the same with a NEMA 1 enclosure. The
Flatpak will be grounded by the installation onto the panel.

Chapter 4: Antenna Installation
Overview
The antenna should be mounted outdoors and as
high up as possible, but able to reach the Mission
RTU radio connection with no abrupt routing of the
coax. Make sure the antenna is not obstructed by
buildings, metal or trees. If attaching to the side of
a building, try to place it as high up on the roof line
as possible. If the Mission RTU is indoors mount
the antenna outside. Integral or attack resistant
antennas are available by special order.
The Universal Antenna Mount consists of three main parts – the curved “L”
bracket, the antenna whip and the coaxial cable.
1. Install the Mounting Bracket. Before mounting the bracket, verify that
the antenna cable will reach the intended mounting area from the RTU. The
Universal Antenna Mount can be attached in a variety of
ways. It can be mounted directly on the face of a at surface,
mounted to a conduit, or even to a tower leg using the included
pipe clamps.
2. Install the antenna cable and antenna whip. After installing
the main bracket, connect the SMA-M cable connector to
the SMA-F connector on the main board (hand tight and 1/4”
turn with a wrench). Then, unscrew the bolt from the molded
antenna base. Feed the molded antenna base through the square cutout on the
bracket. Place the molded antenna base in the circle cutout. Secure the molded
antenna base to the bracket with the bolt. Ensure that the weight of the cable
does not damage the antenna base. There should be enough slack in the cable
so as it does not rest or touch the top surface of the mounting bracket.
Proper Antenna Installation is Vital
The most common cause of poor RTU performance can be attributed to a poor
antenna installation. With the new cellular radio transceivers, antenna installation
15
becomes even more important. For
best operation of the Mission RTU, the
antenna should be mounted outside
any site structures.
Antenna Installation Tips
DO mount the antenna as high as
possible, preferably above the roof.
DO mount the antenna above all metal
surfaces close to the installation.
DO run an 8 to 10 gauge ground wire
to the Mission RTU enclosure
(back plate for NEMA 4) to ensure that the antenna base and RTU have the
same ground potential.
DO wrap excess coax in loose circles of 8-12 inches in diameter. Pinching or
tight bends in the coax can restrict the radio signal path in much the same way
water ow is restricted through a tight bend in a pipe.
DO NOT mount the antenna inside a metal control cabinet. Although berglass
cabinets may only attenuate the signal a small amount, Mission always
recommends the antenna be mounted outside and above all surfaces.
DO NOT mount the antenna on the side of a metal cabinet. Metal surfaces will
reect the radio signal, preventing it from traveling in all directions.
DO NOT mount the antenna underground, in a dry well, or inside a “canned” lift
station.
DO NOT mount the antenna horizontally (sideways) or bend the antenna whip.
DO NOT cut, lengthen, or shorten the coaxial cable. Mission can supply antenna
extension cables and connectors up to 50 feet. For lengths above this limit,
another RTU mounting location should be made.

Chapter 5: RTU Startup
1. Power the Mission RTU with the 12 VDC battery only. Do not power the
station yet. Black lead rst, then red (12 VDC). Watch the LEDs to make sure
it powers up as previously described. You should then see the vertical status
LEDs on the lower right corner of the main board light up in a up and down
pattern and then the horizontal digital LEDs above the digital inputs will scroll
side to side, then all go out. (See gure 2 for LEDs). Allow the unit adequate
time to perform its power-up sequence and synchronization to the network.
Five to ten minutes is generally adequate for the process to successfully
conclude.
2. Next you should see a single solid green LED light up on the vertical status
LED stack on the lower right corner of the main board and the radio status red
LED on the lower left corner of the radio light up solid.
3. As the green LED on the vertical stack descends the radio status red LED
should start blinking. Once the LED on the vertical stack reaches the bottom
“BAT” LED, the green carrier LED should come on and you should hear 3
beeps from the buzzer. This indicates the unit has connected and is online.
NOTE: When the RTU is online the green carrier LED will remain on and
the red radio status LED will continuously ash. The top “A” LED on the
vertical status LED indicator should be on after the unit transmits its rst
transmisson and the “DAL” LED should be ashing rapidly. The “TRB”
LED will be on due to no AC to the main board yet. Once the AC is turned
on the “TRB” LED will go out.
4. Wire the AC power. The Mission RTU is powered by a 12 VAC transformer
with ying leads that has a primary input. The primary input (black wires) can
handle 120 VAC and the secondary output (red or yellow wires) outputs 12 -16
VAC.
CAUTION: It is very important to ONLY provide 12-16 VAC to the Mission
main board AC input. If 120 VAC is applied to the main board, it will cause
permanent damage. The transformer should NOT be mounted in the
Mission RTU enclosure. Mount the transformer in the control panel.
17
5. Check the wiring connections before powering the pump station. If all wiring
is good, power the pump station and immediately focus on the Mission main
board. Check to ensure the Mission RTU is still operating. If somehow a wiring
mistake has been made and 120 VAC is being fed to the Mission RTU main
board, it will be evident. If there appears to be a mistake, immediately remove
power before it permanently damages the Mission RTU unit. If power is OK,
proceed to testing the RTU.

Chapter 6: Test the Installation
It is HIGHLY RECOMMENDED that the following tests be done to ensure the
customer or end user gets proper notications.
1. Test AC power. Check the yellow “TRB” LED. It should not be illuminated. If
it is, the Mission RTU is not wired properly for 12 VAC. If the yellow LED is
blinking then one of the alarm inputs (4 – 8) does not sense the 1000 Ohm
end-of-line resistor. The yellow LED should be off.
2. Test the battery. The red “BAT” LED should be off. If it is on, check the battery
wires then check the battery voltage. If below 11.8 VDC, the red “BAT” LED
will be blinking as it is charging. If it measures below 10 VDC, then the battery
may be bad.
3. Test the radio connection. Check the red radio LED. It should be blinking.
The green carrier LED should be on. If not, call technical support at 877-993-
1911.
4. Test the vertical status LEDs. A good installation ALWAYS has the green “A”
LED on, while the green “DAL” LED is blinking quickly. The “SID” LED should
be off. The Green “REG”, “ACK”, and “PAG” LEDs should remain off except
when data is being sent. The “REG” LED will light during transmission. All
yellow and red LEDs should be off. The red “BAT” LED will blink when the
Mission RTU is charging its battery.
5. Test the alarm inputs. Check the horizontal input LEDs on the Mission main
board. If any LEDs are blinking, the input does not sense a 1000-Ohm
resistor. Check the wiring / connections of the resistors. Pump run inputs (1 –
3) do not blink. Test any alarm relay input by putting them into an alarm state.
If this is not possible, short out the 1000-Ohm resistor at the relay/terminal
connections. The corresponding input LED should turn on. If not, check
wiring/connections. Ensure that all alarm inputs when CLOSED cause the
corresponding Mission RTU input LED to turn on. It is recommended that you
work with Mission Technical Support to conrm that alarms are being properly
transmitted and received on your web portal.
19
6. Test the pump runtime inputs. Turn on pump 1. Mission RTU input 1 LED
should illuminate. If not check the wiring and/or end-of-line resistors. Repeat
step for pump 2 and 3 if used.
7. Test the high level alarm. It is recommended to perform this test. Open the wet
well. Pull the high-level oat up and put into alarm condition. Ensure that the
Mission RTU input 4 LED turns on. If not, check the wiring (wet well module if
used). Also check the high level oat itself. Do not leave the installation until
this alarm function is working. The alarm should be received and viewable by
Mission Technical Support within a matter of seconds (typically less than 15
sec.) following the debounce period.
Wet Well Module: By performing the above pump run and high-level alarm
tests you will have tested the wet well module. The green power LED should
always be on. The yellow pump run LEDs come on when pumps are running.
The red high level alarm LED should turn on when the high oat is closed.
Verify that the customer is receiving the correct alarm notications from the tests.
20
Chapter 7: Site Commissioning
Mission does not consider an installation complete until it has been fully tested by
the end user.
It is imperative that ALL alarm points are tested and that alarm notications are
accurately received and acknowledged by the customer or end user. All alarm
recipient phone numbers, pager numbers, fax numbers and e-mail addresses
must also be tested. The customer or end user must ensure that the system is
properly setup with Mission for e-mail or fax notication of unit trouble or outage
alerts. Additionally, it is recommended that the customer or end user test all alarm
points at least every 6 months to ensure all electrical components and alarm
parameters are still functioning as desired and that alarms are being received
and acknowledged by all recipients.
Completion of the unit setup form is important. It is how Mission congures and
labels your unit inputs. Please provide us with accurate location coordinates
(latitude and longitude). This is needed for plotting of the unit on your homepage
map. A street address and zip code will also work. Provide your name and cell
number so we can contact you with any questions. Email the setup form to
setupforms@123mc.com. Mission cannot enable RTUs until setup forms are
received. In emergencies we can take this information over the phone, however,
we still require you to email it to us for documentation reasons.
Once the setup forms are received and entered, the RTU can be enabled for
alarming and reporting.
It is recommended that you review the online manuals for a more specic and
detailed operation of your RTU and web portal. This can be found on your menu
selection in the DOWNLOAD folder under DOCUMENTS.
CONGRATULATIONS! Your unit is now ready for use. Visit www.123mc.com or

for proper operation. Digital status LEDs are
only active when unit is online.
Make sure the 1,000 ohm resistor is installed
at the relay or input. Check connections for
tightness.
Contact Mission Technical Support at (877) 993-1911 if any problems exist with
your RTU or web portal.
If you have a laptop computer with a serial port and cable it would be helpful
to hook up to the main board before troubleshooting. (This is not necessary to
still be able to troubleshoot effectively) but does help in in-depth monitoring of
the board status through the use of hyper-terminal usually accessible through a
program that is built in to your computer. Contact Mission Technical support for
assistance.

Appendix A: Terminology
M110 - RTU with real-time alarms and hourly check-in of pump reports and
analog values. Manual remote control is an available option with this unit.
M800 - RTU with real-time alarms, pump reports and analog values. Automated
remote control is another available option with this unit.
NEMA 1 enclosure - Steel enclosure with battery inside.
NEMA 1 Flatpak enclosure - Steel enclosure that mounts inside the control
panel. Battery is housed outside of the enclosure.
NEMA 4X enclosure - Water resistant, berglass outdoor enclosure with battery
inside.
Power and Backup Power
The M110 and M800 RTUs operate safely on 12 VAC via the supplied
transformer. They include a 5 amp hour battery with a charging circuit that
powers the units for 30-35 hours during a power failure. There is an automatic
alarm for external power failure and low battery condition. The included 120 to
12 VAC transformer mounts outside the RTU to protect the main board and radio
from voltage spikes.
Digital Inputs
There are 8 dry contact inputs on M110 and M800 series that can be used for
sensing alarms, pump status, as well as accumulating pump runtimes and pump
starts. Both models can be equipped for an additional 8 digital inputs with the
optional Digital Expansion Board to give you a total of 16 digital inputs.
Analog Inputs
There are 2 analog inputs on M110 and M800 series RTUs that can be used to
report pressure, level, chlorine pH or any other dynamic readings by way of a
4-20mA or 0-5V transducer. The M800 can be expanded to 6 analog inputs. All
analog inputs support 4 threshold alarm settings that can be remotely congured.
Model 110 alarm thresholds are not supported by the expansion board but are
supported on the two analog inputs on the main board.
23
Input Wiring Supervision
All digital input wires use end-of-line resistors for wiring supervision. Wiring
supervision detects if input circuit wires become broken or disconnected and are
thus unable to respond to alarm conditions. We’ll tell you if a circuit wire breaks
or becomes disconnected. N/O contact operation.
Key Reader Input
The included key reader allows on-site personnel to log a site visit and
acknowledge and suspend alarms while service is performed at the station.
Management can track the key entries for productivity and regulatory reporting
purposes.
Pulse Inputs Options
2 pulse inputs can be used to report data such as ow, water meter or rainfall
totals. If no rainfall data is monitored at the site, Mission’s web site presents data
from the closest National Weather Service reporting station. Pulse inputs are
available with either the Pulse Option Board or the Analog Option Board.
Digital Outputs
The M110 and M800 series support 3 relay outputs that can be remotely
controlled. These can be used for any purpose including turning on pumps, wells
or security lights. Multiple M800s can be linked so an event at one station causes
a relay change at another. Mission’s Tank and Well Control option and Intertie
rely on this feature.
NOTE: It is highly recommended that the use of a 12 VDC coil interposing
relay be used in conjunction with the Mission main board reed relays to prevent
overload damage to the main board. Make sure the load side of the relay can
handle the rated AC voltage of the load you are switching on or off.
