4.1 Max RPM cut-off
The maximum motor RPM can be limited to reduce the possibility of overfeeding chemical into the system. Note that the pump’s display will still reference values calculated from the 100% motor speed MAX Flowrate value (see section 4.2). Also, the pump % motor speed will still be referenced from 190 RPM, the maximum possible motor RPM. For example, if the pump speed is set for 25%, the display will indicate 47.5 RPM. The prime mode RPM is limited to the Max RPM value.

4.2 MAX Flowrate (output calibration)

Press ENTER to set.

The MAX Flowrate value is equal to the pump’s measured fluid output in milliliters per minute, at the 100% motor speed adjustment setting. The pump uses the MAX flow rate value to calculate motor speed for various operating functions and to display output values.
The MAX flow rate value can be adjusted at any time. To achieve high accuracy, a field calibration under the actual operating conditions should be performed and the Max Flowrate value changed to reflect the calibrated amount. Multiply the Max Flowrate value by the percentage of error at your calibrated flow rate to obtain the new Max Flowrate value.
Select Max Flowrate and Press ENTER button.

– Max Flowrate Input Max Flowrate:

Flowrate = ML/min Press ENTER to set.

Select <-Esc on the main menu screen to exit the menu structure and enter the run mode.
NOTE: Your actual output may vary due to fluid viscosity, fluid temperature, suction lift height, piping system layout, manufacturing tolerances and to a lesser degree, and variations in system pressure.
To achieve high accuracy, the pump’s output should be measured (calibrated), and the MAX Flowrate value (in milliliters per minute) updated, whenever any of the following conditions exist:

To calculate the Max Flowrate:
To determine the amount of error at your output setting, divide the actual output amount by the indicated output. Then multiply the resulting percentage of error by the Max Flowrate value currently showing in the pump.

! At the initial pump start up. ! When the piping system configuration is changed. ! When the suction lift height is changed.

Example: If the pump display indicates the output is 170 ml/min but the actual measured output is 160 ml/min, calculate the percentage of error by: 160/170 = 0.941. Multiply the Max Flowrate value by 0.941 and enter this new value.

Wiring for sensor can be connected directly to a MD3® pump. Pump will stop pumping if sensor detects no flow. A relay will then close allowing for remote alarm indication or initiation of a back-up pump. Install FVS Flow Sensor Flow Verification Sensor should be installed on discharge side of pump.
Confirm FVS flow range – Flow Verification Sensor (FVS) will only function within its operating range. See chart for available ranges.
NOTE: If pump output is less than 30 ml/min, sensor will not detect chemical and a signal will not be sent to pump, resulting in an alarm condition.
NOTE: For low viscosity (water-like) fluids only. Consult factory if attempting to use with viscous fluids.

CHEM-FEED® MD3 4.6 DFD (Diaphragm Failure Detection)

Page 27

The MD3® is equipped with a Diaphragm Failure Detection System which is designed to stop pump and provide an output alarm in event diaphragm should rupture and chemical enters pump head. At the default adjustment setting of 75%, the pump will detect a chemical with a conductivity reading greater than 500 microsiemens. The system sensitivity can be increased to 100%, reducing the conductivity to 430 microsiemens. Chemicals with conductivity of less than 430 microsiemens will not be detected.

This system is capable of detecting presence of a large number of chemicals including Sodium Hypochlorite (Chlorine), Hydrochloric (muriatic) Acid, Sodium Hydroxide, and many others. System will not be triggered by water (rain, condensation, etc.) or lubricants.

If system has detected chemical, pump diaphragm must be replaced and pump head must be thoroughly cleaned. Failure to clean pump head will void warranty.

If DFD alarm occurs, pump will stop, close an alarm output, and screen will flash DFD with an alarm icon.

4.7 Remote/Local Control
The MD3 can be configured for Remote control only, Local control only, or either (disabled).
When set for Remote control only, all touch pad buttons except the menu button are disabled. To completely lock out the menu, configure a password (see page 12, section 8). If REMOTE ONLY is selected, the user is prompted to select an input operating mode which must then be used when operating the pump.
When set for local control only, all input signals including the remote start/stop are disabled. Note that the “contact closure input” menu setting (section 4.4) is switched to “disabled” while LOCAL ONLY is selected. This menu setting will return to the previous setting when REMOTE ONLY or DISABLED is selected.
NOTE/CAUTION: With certain firmware versions of this pump, the “contact closure input” may need to be set again to the desire setting “Close, Open, Disable” when activating REMOTE ONLY. Always re-confirm “contact closure” setting when running in REMOTE ONLY.

5.0 Output Setup (alarm relays)

Below is the menu structure for the Output Setup selection. The layout of the Output Setup menu is similar to the Input Setup menu. Outputs were designed to directly communicate to SCADA systems, alarms, data loggers, backup pumps, pumps to operate in sync, pumps to operate proportionally, and other external devices.

To prevent false alarms due to pump start-up and closed loop applications, a trigger delay time can be configured to delay the relay switch action. The delay time unit of measure is seconds.

CHEM-FEED® MD3 6.0 Pump Maintenance

Page 31

CAUTION
!
CAUTION
!

Prior to service, pump clean water through pump and suction / discharge line to remove chemical.
Always wear protective clothing, face shield, safety glasses and gloves when working on or near your metering pump. Additional precautions should be taken depending on solution being pumped. Refer to MSDS precautions from your solution supplier.

6.1 Routine Inspection and Maintenance
Pump requires very little maintenance. However, pump and all accessories should be checked weekly. This is especially important when pumping chemicals. Inspect all components for signs of leaking, swelling, cracking, discoloration or corrosion. Replace worn or damaged components immediately.
Cracking, crazing, discoloration during first week of operation are signs of severe chemical attack. If this occurs, immediately remove chemical from pump. Determine which parts are being attacked and replace them with parts that have been manufactured using more suitable materials. Manufacturer does not assume responsibility for damage to pump that has been caused by chemical attack.

6.2 Cleaning Pump
Pump will require occasional cleaning, especially Injection fitting, Footvalve / Strainer, and pump head valves. Frequency will depend on type and severity of service.
] Inspect and replace pump head valves as required.
] Periodically clean injection / check valve assembly, especially when injecting fluids that calcify such as sodium hypochlorite. These lime deposits and other build ups can clog fitting, increase back pressure and interfere with check valve operation.
] Periodically clean suction strainer.
] Periodically inspect pump housing (enclosure) for chemical attack. Protect pump housing from continuous exposure to chemicals, such as drips or fumes from surrounding equipment and plumbing.

6.3 Replacing the Pump Diaphragm
] When changing the diaphragm, the pump head chamber and pump head cover should be wiped free of any dirt and debris. The pump stroke must be FORWARD when installing the diaphragm, and BACK when installing and tightening the pump head.
] When replacing the pump diaphragm, note the order of parts per the illustration below:
] Tighten pump head bolts in star-shaped pattern, so as to not overtighten one side. Tighten bolts to 38 in-lbs. (Note: Check bolts and torque after 1-2 hours, as material may soften after initial break-in period. )
