Chapter 2: Site Survey & Connectivity Test Prior to installation, please complete and submit the RTU Installation Form via fax ((770) 685-7913) or email (setupforms@123mc.com) 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.

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.
Antenna Best Practices Don’t Mount the antenna outside as high as Mount the antenna underground, in a dry well, possible, preferably above the roof or other or inside a canned lift station. objects. Mount the antenna above all metal surfaces Mount the antenna horizontally or bend the close to the installation.
Chapter 4: RTU Installation and Wiring Locate the RTU as close as Enclosure Options possible to the control cabinet while considering the antenna cable NEMA 4 length. Mount outdoors on unistrut or a wall. Allow Warning: Turn off station clearance for hinge (left) power.

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) (M150)
Page 13
On M850 RTUs, D1–D8 (on the main board) can be configured 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.

6. Terminate analog inputs. Two Figure 3: isolated analog inputs are available Analog Input Wiring on the main board (refer to figure 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: If power to output relays is supplied by Mission aux power port it is software configurable 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.
Chapter 5: RTU Startup Figure 5: 1. Power the Mission RTU with the 12 VDC battery only. Connect Battery Wiring the black lead first, 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.
Chapter 6: Test the Installation It is imperative that alarm points are tested and that alarm notifications 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.

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 float up and put it into alarm condition by tipping it.
Chapter 7: Site Commissioning Enable the RTU for alarm call-outs by calling technical support. Setup Forms Ensure setup forms have been submitted to Mission technical support. Verify proper labeling on your web portal and the wiring diagram on the Mission RTU. Users with administrator credentials have the ability to make changes to the web portal, if necessary.
Appendix A: Terminology Alarm Inputs A digital or analog input that is configured to dispatch a notification when the alarm state or threshold is reached. Analog Inputs Two analog inputs on M150 and M850 series RTUs can be used to report pressure, level, chlorine pH, or any other dynamic readings by way of a 4–20 mA or 0–5 V transducer.

The requirement for an end-of-line resistor is software configurable for fault (requires resistor) or no fault. M150 vs. M850 Generally, the M850 is more appropriate where analog sensors are present, at master lift stations, and for remote control applications. Both RTUs provide real-time alarms. The M150 accumulates pump starts each hour whereas the M850 reports real-time pump state changes.
