2904TV Silver Service®, 6504TV Hercules®

Models 2904-TV and 6504-TV combine maximum versatility with the power needed to operate small to medium sized draw curtains. Equipped with electronic frequency drives, the TV series machines are the most versatile in the ADC line. Designed for draw applications these machines offer a multitude of parameters that can be programmed in the field to meet a variety of applications. Parameters such as run speed, maximum obtainable speed, minimum obtainable speed, acceleration ramp time and deceleration ramp time are easily changed at the drive. Each machine is provided with deceleration limit switches which allow the machine to decelerate to a stop rather than abruptly stop at the end of its travel. These machines also feature emergency overtravel limit switches and push buttons which bypass the deceleration ramp time and shut the machine off immediately. The operation of these machines is Start/Stop/Reverse from any point of travel and low voltage control is standard. If versatility is a project requirement, this series of machines is the best option.

Cable tension device (CTD-1) is available as an option for machine in this series.

  • Rotary Limit Switches for decel to full open decel to full closed positions as well as overtravel.
  • Low Voltage Control - 24 vac
  • Remote Control Station (RCS1-TV)
  • Fast stop (F-Stop) loop and push-button which provides instantaneous stop of the machine, bypassing the deceleration ramps.
  • Variable speed operation from 0 to 86 fpm
  • Machine Guard
  • Helical Grooved Drum 5"L x 10"D
  • Channel Steel Base
  • Connects to 120 volt power supply (220 volt single -phase and 230 volt, 3-phase is available as options)
  • Approximate shipping weight 120 pounds
