CAUTION: Any arc welding on the skid and/or associated equipment and piping can permanently
damage solid-state electronic equipment. Welding can cause immediate failure
or reduce electronic equipment life and void the warranty.
To protect electronic equipment prior to any arc welding (including repair welding), disconnect
all electrical connections including ground, and remove batteries, or completely
remove the electronic equipment from the compressor.
It is good practice to attach the welding ground clamp as close as possible to the area
where the welding will occur and to use the lowest practical welder output setting. Welding
must not cause a current flow across any compressor bearing surface, including but
not limited to crankshaft and crosshead bearing surfaces.
The battery-powered, programmable Proflo
is an electronic microprocessor-based
switch that senses slow-flow or no-flow
conditions in the compressor cylinder force
feed lubrication system to facilitate alarm
and/or shutdown. It eases force feed lube
system operation by accurately monitoring
cycle time and system performance.
Operators use this information to optimize
force feed lube and reduce operating costs.
The Proflo monitor works through a
magnetic pin that cycles back and forth as
the divider valve piston moves. The
magnetic pin housing normally threads into
the divider valve. The monitor box housing
slides onto the pin housing and two hexsocket
set screws hold it in place. The liquid
crystal display (LCD) indicates:
1. Total operating time of the force feed
lube system in hours.
2. "Average", "Last" and "Current" cycle time of the divider valve in seconds.
3. Total divider valve cycles.
4. Remaining battery life in percent.
5. Alarm set time for no-flow indication (programmable from 30 to 240 seconds).
6. Alarm wiring mode: Normally Open or Normally Closed.
Proflo electronics come with reverse polarity protection/correction that automatically corrects a
reverse polarity output connection on both pulse and alarm outputs.
