The PBS Control System is a Surface / Wall Mounted enclosure which contains from 1 to 4 Groups of ( Dead Man ) Rear Illuminated Push Buttons. The Push Buttons are used to move the Hoists either up by pushing and holding the Up Button or down by pushing and holding the Down Button. When the button is released the Hoist will stop. The System also contains an On/Off Key Switch with Indicator Lamp. A re-set Emergency Stop Button is provided that will trigger a contactor that will trip the breakers feeding the Hoists and thereby shutting down the entire hoist system in case of an emergency. The control signal going to each motorized rigging device is a 2 wires, 24V D.C.signal will that determines the direction of the movement in association with its polarity.
