MDi’s controller
for Reciprocating compressors is a simple shutdown
panel that incorporates many unique features developed
over years of experience. Simple design and very flexible
configuration allows the same controller to setup
for dif ferent skids avoiding having custom panels
to be built for different applications. Single board
microprocessor based electronics allows for achieving
maximum throughput and reducing maintenance costs.
Micro-Design controllers are designed specifically
with this in mind. They incorporate all of the unique
features required, but never available, to the O E
M or Compressor Packager.
Micro-Design has developed this new standard for
reciprocating compressor control by combining the
power of the NP 60-microprocessor board, which includes
more than 96 I/O points on a single board. The software
is very comprehensive and allows the user to configure
the controller to fit most applications by simply
setting the set points and other start/stop sequence
parameters thus giving the end user the ability to
customize the compressor program to fit any particular
needs without having to Send for a new chip from the
factory”.
The standard NP-60 recip. compressor controller
comes with a preloaded program. This program includes
the ability to address all set points, and to activate
or deactivate each point, as they relate to your particular
application. The standard preloaded software can be
configured to operate motor drives or engine drives.
The program includes the ability to operate as a simple
shutdown panel or perform complete start/stop/run
sequences where automatic operation can be achieved
based on external control parameters.
The NP-60’s will keep you running even if minor
system upsets occur which can easily knock out the
controller on false alarms. Automatic Start/Stop can
be controlled either by Suction Pressure or remotely
by other equipment such as Plunger Lift controls,
SCADA Systems, etc. Governor control and Air-Fuel
Ratio are optional features that can be easily added
to the system.
All controllers include easy-toread digital displays.
The display continually scrolls to show user selected
screens. This feature allows quick and simple viewing
of all conditions and set points. Set point changes
are easy to enter via the front keypad. Set point
security can be set as required. The panel also includes
throttle control, and operating switches such as start,
stop, reset, manual, auto, test, etc.
The Single board solution reduces controller failures
due to vibration and minimizes maintenance costs and
number spare parts.
