Solution: Hook up a repeat cycle timing relay with an on/off switch to the backup compressor and adjust. For example, on 1 min, off 2 min, at a 33% duty cycle. Off-time can be adjusted up or down to handle slow or busy days.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
