Baldor introduces a new line of pump and fan controls packaged with the popular VS1PF series of drives. With industry standard features such as a Circuit Breaker with lockable disconnect, Hand-Off-Auto (HOA) and Local/Remote Bypass, the package meets typical HVAC specification requirements. All controls are pre-wired and contain standard features designed to meet the majority of HVAC applications with knock-outs for line, load and control signal.

The VS1PF has built in features for standard HVAC applications and also includes advanced controls such as:

• External and Internal PID control
• Sleep/Wake functions for energy savings when the system is on standby
• Motor pre-heat to eliminate motor condensation in damp environments.
• Flying start to catch rotating loads when for example backpressure causes a pump to spin or updraft results in fan rotation.
• Automatic Energy Savings Mode

However, Baldor didn’t stop there, utilizing an Integrated Electronic Bypass Module, it can automatically switch to bypass when a Critical Fault occurs on the Drive. A remote “run” command can easily be accommodated as well allowing your system to send down the command instead of a physical switch needing to be turned. The standard control station includes a Speed pot for operating, Hand/Off/Auto Switch and an ASD/Bypass/Test Switch for ease of control. LED indicating lights are provided for Power Indication, ASD Mode, Bypass Mode or Fault.
