4.5 Set FVS (Flow Verification System)
Used to monitor the pump fluid output. If the pump does not dispense fluid
when pump head rotor is turning, the pump will go into an alarm mode and
stop. Blue-White offers a flow verification sensor that easily attaches to the
outlet fitting of the pump.
Default settings: 000 (off)
Navigate to Set FVS menu by pressing MENU button, then selecting Input
Setup, and then Set FVS .
Press UP or DOWN arrow to scroll through 0 - 9 on selected digit.
Press RIGHT arrow to scroll over to the next digit to right. If you pass your
desired digit, you can easily scroll back by continuously pressing RIGHT
button.
Press ENTER to save the changes and exit FVS screen.
To navigate back out of menus, select <-Esc and press ENTER button at the
bottom of every screen menu until you see the Run Mode screen displayed.
Flow Verification Sensor is designed to give you two installation options.
Sensor can be installed:
!
Directly onto pump head of MD3® pump, discharge side.
!
Anywhere on discharge side of MD3® pump.
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.

4.6 DFD (Diaphragm Failure Detection)
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.
