Electronic signal converters
Micropace™ LMI
Micropace™ Range
•The Micropace™ line of rugged, low cost control modules provide
you with the ability to proportionally adjust the output of any LMI
AA7/AA9/B7/B9/C7/C9 metering pump.
•Adjustment can be made by multiplying (MP-500-M), dividing
(MP-400-D) or by direct proportional response to 4-20 mA signal
(MP-100).
•These IP65 compact modules are powered by the pump and prewired for quick and easy installation.
Specifications
• Power supply: 15 V DC (supplied by LMI Pump)
• Ambient temperature (-20°C to 60°C)
MP-100 A/D converter
• Input signal: 4-20 mA isolated
• Input impedance: 100 Ω
• Max. input voltage: 42 V DC
• Output: 0-100 strokes/minute, Fixed span
Typical installation MP-100
MP-400-D Pulse divider
MP-500-M Pulse multiplier
• Input signal: contact closure or open collector
- ON (close) resistance: 5 KΩ max.
- OFF (open) resistance: 100 KΩ min.
- Mini ON time: 10 ms
- Mini OFF time: 20 ms
• Divide or multiply ratio: 1-1023
• Max. input frequency: 30 Hz (MP-400-D)
• MP-500-M based on multiply ratio.
Cycle must be completed.
Loop control MP-100
• Output signal: contact closure
- MP-400-D: based on input frequency and ratio
- MP-500-M: 100 pulses/min (fixed)
Typical installation MP-400-D / MP-500-M

Installation
MP-100
1. Disconnect signal source supply voltage prior to connect your
Micropace™.
Method of triggering
MP-400-D and MP-500
Voltage free switch
2. Insert the 4 pin plug in your LMI pump. The socket is located
under the control panel. The pump must be in external mode.
3. Connect the other cable to the signal source.
Polarity is: (+)White
(-) Black
NPN Transistor
MP-400-D / MP-500-M
1. The MP-400-D and MP-500-M signal converters may be preset
before connection to the pump or signal source, or may also be
adjusted after connection.
2. Open the Micropace™ cover by removing the four screws holding
the back cover on.
3. Preset the divide or multiply ratio by using the small DIP
switches. Add the value of all switches pushed on the right (ON)
to know the selected ratio. Use a ball pen or a small screw driver
to slide switches. On exemple below (1+4+8=13). This allows
you to select any ratio between 1 and 1023.
PNP Transistor
Opto Isolator
Transistor must be able to switch 2 mA @15 V
Dimensions (in mm)
4. Replace the cover and the four screws.
5. Proceed as for MP-100 §2 and 3.
