Chapter 2: Site Survey & Connectivity Test
Prior to installation, please complete and submit the RTU Installation Form via fax ((770)
685-7913) or email ([email protected]) so Mission can set up the new unit(s)
on your web portal. New customers must also complete and submit both forms within
the New Customer Packet. The web portal can be accessed with the login credentials
you provided within the Account Setup Form. Once completed and entered by technical
support, alarms can be enabled for your RTU(s) immediately after installation so you can
perform end-to-end testing.
By powering the RTU and testing connectivity before mounting the hardware, you can
optimize the signal strength for years of trouble-free communication. The test only takes
a few minutes since the included battery can provide temporary power. Refer to Chapter
3 when positioning the antenna for details on best practices.
1. Remove the RTU from the box and place it on or near the control panel it will be
monitoring. Remove the antenna cable and antenna whip from the package and
hand-tighten the SMA-M connector to the radio SMA-F connection on the RTU
(see Figure 1).
2. Screw the whip antenna onto the molded antenna base and place it outside as high
as possible. Mount the antenna to the aluminum bracket.
Warning: Hand-tighten the nut on the underside plus 1/4 turn with a wrench. Do
not overtighten.
3. Power the RTU with the 12 VDC battery (see Figure 1). Connect the negative (black)
lead to the battery and then connect the positive (red) lead. Once the sequence is
completed, you will hear three beeps from the buzzer. This indicates the unit has
connected to Mission servers. If the RTU does not connect after two attempts,
refer to Appendix D: RTU Boot-up Sequence, Appendix E: Troubleshooting, or call
technical support.
4. Notice the Signal Strength reading on the LCD as shown in Figure 1. The goal is
to mount the antenna where the signal is the strongest. A -75 dB signal is better
than that of -100 dB. Temporarily position the antenna for about a minute in a few
locations and take note of the signal strength.

Chapter 3: Antenna
Installation
Overview
The antenna should be mounted outdoors
and above other objects. By optimizing the
placement of the antenna, you increase the
chances that the radio can communicate
with more than one cell tower. The coaxial
cable should reach the Mission RTU radio
connection with no severe routing of the
coaxial cable. Consider where the RTU will
be mounted in relation to the location of the
antenna.
1. Install the antenna cable and antenna
whip. Connect the SMA-M cable connector
to the SMA-F connector on the main board
(see Figure 1). Unscrew the nut from the
molded antenna base. Feed the molded
antenna base through the square cut out
on the bracket. Place the molded antenna
base in the circle cutout.
Warning: Secure the molded
antenna base to the bracket with the
nut. Hand-tighten the nut, plus ¼ turn
with a wrench. Do not overtighten.
2. Install the mounting bracket. Mount
the Universal Antenna Mount directly on the
face of a at surface or a metal pipe using
the included pipe clamps (placing above
any obstructions).

Antenna Best Practices
Do Don’t
Mount the antenna outside as high as
possible, preferably above the roof or other
objects.
Mount the antenna underground, in a dry well,
or inside a canned lift station.
Mount the antenna above all metal surfaces
close to the installation.
Mount the antenna horizontally or bend the
antenna whip.
Coil excess coax in circles of 5 to 7 inches in
diameter. Pinching or tight bends in the coax
can restrict the high frequency/low power radio
signal path in much the same way water ow
is restricted through a tight bend in a hose.
Mount the antenna inside a metal control
cabinet. Even berglass cabinets degrade the
signal.
Ensure that the weight of the cable does not
damage the antenna base. There should be
enough slack in the cable so it does not rest or
touch the top surface of the mounting bracket.
Mount the antenna on the side of a metal
cabinet or adjacent to a tank. Metal surfaces
will reect the radio signal, preventing it from
traveling in all directions.
Incorporate a drip loop when installing the
cable to prevent water from penetrating into
the building or enclosure.
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 considered.
Wiring Best Practices
• Signal cables should not run parallel with high voltage AC wires (load conductors).
• Where signal wires and load conductors must cross, do so at right angles.
• High voltage should not enter the Mission RTU. Mount the supplied transformer outside the
Mission enclosure.
• Lay wires in wire trays with the excess near terminations. Replace wire race covers (follow
NEC and your local/state electrical codes requirements).
• Cables used for digital and analog inputs should be 18 to 22 gauge, shielded, twisted pair
wire with the shield connected to ground at the RTU and not on the other end of the cable
(to prevent ground loop current).
• MOVs can be installed across AC contactor coil terminals to shunt voltage spikes away
from the RTU inputs and other electronics in the panel. Voltage spikes can be caused
by coils de-energizing. The included MOVs are rated for 120 V circuits and will suppress
excess voltage above 150 V. These parts are application dependent. They have a nite
lifespan and will need to be replaced over time.

11
Chapter 4: RTU Installation and Wiring
Locate the RTU as close as
possible to the control cabinet while
considering the antenna cable
length.
Warning: Turn off station
power.
1. Mount the enclosure.
2. Cut the conduit and wiring
holes. Drill and attach the
conduit in the control cabinet and
Mission RTU. Use sealant where
appropriate.
3. Pull the wires and cables.
4. Ground the RTU. Use 12 to 14
gauge green wire to connect the
grounding lug on the backplate
in the RTU to the stations Earth
ground (refer to Figure 1).
Enclosure Options
NEMA 4
Mount outdoors on
unistrut or a wall. Allow
clearance for hinge (left)
and key reader (right).
Consider the NEMA 4 for
indoor application where
wash-downs occur.
Conduit connections
can enter from bottom,
but leave space for the
included battery.
NEMA 1
Use indoors where no wash-downs occur.
Allow for space on bottom of the enclosure
for the battery.
FlatPak
Mount inside the control cabinet.
Two large holes are provided for through-wires.
Place battery inside the control cabinet.

5. Terminate digital inputs. Refer to the wiring diagram on the M150/M850
cover/door and RTU Installation Form in the packing box. Record input names
on the setup form and the diagram.
The default digital input (DX) connections are as follows:
D1—pump 1 (M150 runtime accumulator, M850 status and runtime accumulator)
D2—pump 2 (M150 runtime accumulator, M850 status and runtime accumulator)
D3—pump 3 runtime or simultaneous pump (1 and 2) runtime accumulator*(M150)
D4—high level oat
D5—pump 1 fail
D6—pump 2 fail
D7—phase fail
D8—unassigned or multiple pump runtime accumulator*(M850)
MyDro Digital Inputs feature software selectable input characteristics including:
• dry contacts with wire fault supervision (requires 1000 Ohm end-of-Line (EOL) resistors)
• dry contacts no wire fault supervision (NF)
• strap on load sensors (Mission PN OP499) with wire fault supervision
• strap on load sensors (Mission PN OP499) without wire fault supervision
The MyDro does not directly support the Wet Well Module. See our technical
document, Wet Well Module with MyDro, if replacing M110 or M800 with Wet
Well Module to MyDro.
Warning: Digital inputs require dry contacts. This means that wires
running to these inputs must not supply any voltage. Use an interposing
relay if there are no dry contacts available.
The digital inputs are set as normally open (N/O) by default. You must use
N/O contacts on pump runtime inputs. You may use either N/O or normally
closed N/C contacts on digital inputs 4 through 8. Notify Mission technical
support (or indicate on RTU setup form) to change the default settings (refer
to Figure 2).Connect the shields of digital input wires to the grounding lug
located inside the RTU.
Pump Runtime Inputs: On M150 RTUs, only inputs D1–D3 can be
congured for pump runtimes. However, they can also be set as alarm inputs.
D4–D8 on an M150 can only be congured as alarm inputs. D3*can be used
for simultaneous runtimes by conguring digital input on touch screen.

13
On M850 RTUs, D1–D8 (on the main board) can be congured as pump
runtime, pump runtime with alarm, or alarm inputs. As an option, the system
can report multiple pump runtimes on M850 RTUs on D8*.
Figure 2:
Digital Inputs—Load Sensor, Supervision,
and Surge Suppression
Wire fault supervision: End-of-line (EOL) resistors are optional
with the MyDro. When utilized and installed properly (at the
far end of the cable wired parallel to the switch) they allow
the system to alarm on a wire fault. Software selection of
this is done from the touch screen. From the cong
screen go to Digital Input setup and then mode.
Choose Digital Input Dry Contact NF for no
EOL resistor (no wire supervision.)

14
6. Terminate analog inputs. Two
isolated analog inputs are available
on the main board (refer to gure
3). These inputs can accept a 4–20
mA or 0–5 V signal. Position analog
channel signal selector*to the left for
a 4–20 mA signal and to the right for
a 0–5 V signal.
Warning: Take precautions
when wiring the analog inputs.
Reverse polarity may damage
the main board or the sensor.
The auxiliary output on the main
board can be used to power the
transducer as seen in Case 1 (250
mA maximum). When using the
auxiliary output, be aware of the
voltage drop in the 4–20 mA loop
when wiring to the analog inputs. The
aux output supply voltage is software
congurable for 12 or 24 VDC.
7. Wire the output relays. The output
relays are single pole, double throw
and rated up to 30 VDC or 120 VAC
at 5 amp maximum. They are used
for remote control applications such
as Tank and Well, and digital intertie.
You can wire the relay normally open
(default) or normally closed (refer to
Appendix B).
Warning: Relay behavior
on communication failure is
congurable under the Cong.
Menu/Relay Comm Fail Setup
as Deenergize or No Change.
Figure 3:
Analog Input Wiring

15
Warning: If power to output relays is supplied by Mission aux power
port it is software congurable as 12 or 24 VDC. Specify coil voltage of
interposing relays appropriately.
Note: Many items should be considered with remote control applications.
Refer to our Best Practices for Remote Control Applications document.
Wire the auxiliary output to common on the output relay. Wire the coil positive
terminal on the interposing relay to normally open or normally closed on the
output relay. Wire the negative coil terminal to Aux (-).
8. Install the 120 VAC transformer and wire AC power. Mount the transformer
in the control panel (not the Mission RTU).
It is very important to only provide 12–16 VAC to the Mission main board
AC input. Hooking up the transformer backwards will apply 1200 VAC to the
mainboard and cause permanent damage. Do not install transformer in the
RTU. Install it in the control cabinet.
Warning: Connect AC power to the primary input (black wires). Connect
the secondary output (red wires) to the main board input. The transformer
steps the power down from 120 VAC to 12 VAC. Do not turn on station
AC power at this time.

Chapter 5: RTU Startup
1. Power the Mission RTU with the
12 VDC battery only. Connect
the black lead rst, then the red
lead. The LCD will illuminate
start up screen. Once the
radio sequence is complete,
you will hear three beeps from
the buzzer. This indicates the
unit has connected to Mission
servers. Allow the unit two
minutes to perform its power-up
sequence and synchronization
to the network. If the RTU does
not connect after two attempts,
refer to appendices D and E, or
contact technical support.
2. Check the wiring connections
before powering the pump
station. If the wiring is correct,
power the pump station, and
immediately focus on the main
board. Check to ensure the
Mission RTU is still operating.
If a wiring mistake has been
made, it will be evident. If there appears to be a mistake, immediately remove
power. If power is OK, proceed to testing the RTU.

Chapter 6: Test the Installation
It is imperative that alarm points are tested and that alarm notications are
received so they can be acknowledged by the customer or end-user once the
unit is put into production. This includes phone numbers, text messages, email
addresses, fax numbers, and pager numbers.
Additionally, it is recommended that the customer or end-user test all alarm points
every six months to ensure all electrical components and alarm parameters are
still functioning as desired and that alarms are being received and acknowledged
by recipients. Refer to our Spring Cleaning/Fall Fix-It document for testing
procedures.
Complete the following tests prior to leaving the job site:
1. Conrm AC power. Use a voltmeter across the AC terminal to verify
~12–14 VAC is present.
2. Test the battery. Remove the AC fuse and conrm the RTU stays online.
Replace the AC fuse.
3. Test the radio connection. Check the radio status on the LCD screen. It
should read “connected.” If not, call technical support at [phone],
option 2.
4. Inspect the status on the LCD. Analog, digitals, etc.
5. Test the digital alarm inputs. Put each digital input into an alarm state.
From the touch screen press digital and conrm inputs respond as expected.
Mission technical support is available to conrm that data is being properly
transmitted and received on your web portal. A smartphone can be used
otherwise.

19
6. Test the pump runtime inputs. Turn on pump 1. Mission D1 should respond
on the touch screen. 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. Open the wet well. Pull the high-level oat up
and put it into alarm condition by tipping it. Ensure that the digital input four
respond. If not, check the wiring and the high level oat itself.
Verify alarm notications are received from the tests.
Log on to your web portal with the credentials specied
on the Notication Setup form. Go to the Alarms page.
You should see a list of alarm events with event time
and the result.
Call Mission technical support after testing the
installation to enable the device for alarm call-outs. A
technician will verify proper operation of equipment.
