VFD for HVAC systems
The P-Series line of variable frequency drives is available from Cerus Industrial.
Cerus Industrial enhanced its P-Series line of variable frequency drives (VFDs) for HVAC use with control options and safety features, and an application-based commissioning tool called FastApp, designed to save time when setting up a wide range of HVAC applications. With FastApp, HVAC motor control parameters are now easier to set up via the keypad on the drive enclosure, and include a multitude of display and control options. With this wider array of options, users around the world with different HVAC applications can set up their control systems. The enhanced VFDs also have safety features to protect motors from damage due to conditions such as belt loss. If the under level detection feature is selected and the motor runs at a speed above a set amount for longer than a set amount of time and with the load current at less than a set level, the VFD will trip.

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.
