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.

• 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.
2. Cut the conduit and wiring holes. Drill and but leave space for the attach the conduit in the control cabinet included battery. and Mission RTU. Use sealant where appropriate. NEMA 1 3. Pull the wires and cables. Use indoors where no wash-downs occur.

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.

Figure 2: Digital Inputs—Current Sensor, Supervision, and Surge Suppression Wire fault supervision: 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.

AC in connection (see Figure 4B). Mount the transformer in the control panel (not the Mission RTU). It is very important to only provide 12–16 VAC to the Mission mainboard AC input. Hooking up the transformer backwards will apply 1200 VAC to the mainboard and cause permanent damage.
Chapter 5: RTU Startup 1. Power the Mission RTU with the 12 VDC battery only. Connect the black lead first, then the red lead (see Figure 6). The LCD will illuminate the 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.
A smartphone can be used otherwise. 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.

Notification 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.
Mission hosts weekly webinars nearly every Wednesday at 2 P.M. Eastern. The revolving series covers the basics, advanced web portal options, and everything in between. Mission wants to help you get the most out of your system, so please join and feel free to ask questions.
Multiple M850s 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. Consult Best Practices for Remote Control Digital Intertie for more information (123mc.com/literature).
