This last INFO Folder page
shows the hour meters and
number of starts. Power On
Hours is the time that the panel
power has been on. The Running
Hours is the amount of time that
the compressor has been
operating between each start and
stop sequence. The Loaded
Hours is the amount of time that
the compressor has been running
and not running unloaded. It can
also be defined as the number of
hours that the inlet valve is not in
the Inlet Unload Position. The Number of (Compressor) Starts is self-explanatory.
NOTE
Most electric motors are only rated for two cold starts or one hot start per hour. It is
the operator’s responsibility not to exceed the electric motor’s limitation. The control
system allows the compressor to be started when the compressor is ready, not the
motor.
