Push Button Controller

To lower a hoist press and hold the “LOWER” button. The hoist will then run at full speed in

the down direction. The hoist will run until the button is released and/or the hoist reaches its

lower hard struck limit switch.

During installation and setup, the two hoists and the load are installed and leveled and the position

indicator should be set and both match in height (Figure 1).

If one of the two hoists becomes approximately 2.0° out of level the “LEVEL LOW FAULT’ indicator will

light. At this point the low hoist should be raised to correct this matter. Or conversely, the high hoist can

be lowered to match the low hoist.

3.5 To Move an Individual Hoist (refer to Figure 1)

1. Turn and hold the self-centering ‘LEVEL ADJUST’ switch to the hoist needing adjustment.

2. Press the ‘RAISE’ or ‘LOWER’ push button controls until the ‘LEVEL LOW FAULT’ indicator

goes out.

If there is a “MAJOR LEVEL FAULT”, absolutely no further movement of the

hoists will be possible. Please contact Daktronics for help in resolving this

issue.

Note: It is not possible to lower a hoist that is in ‘LEVEL LOW FAULT’.

For example; if a Hoist 1 ‘LEVEL LOW FAULT’ occurs, Hoist 1 can be raised or Hoist 2 can be

lowered. Software prevents the lowering of Hoist 1 or the raising of Hoist 2 to prevent making

the “Out of Level” problem worse.

When operating each hoist, the hoist should always be allowed

to come to a complete stop before reversing directions.

On systems where the optional Over/Under capacity sensors

are present, there is a programmed time delay of one second

between the hoist's ability to change directions.

If any problems arise during any hoist motion, depress the Emergency Stop

button located on the control panel or the Master Control Cabinet.

3.6 Description and Operation of Indicator Lights

“POWER ON”: Indicates that Main Disconnect is turned on and the “System Enable” key switch

is also enabled.

“OVERTRAVEL FAULT”: Indicates that any one of the hoists has traveled too far and is causing a

‘Ground Out’ condition. In the unlikely event when this light is illuminated NO hoist will operate.

Please call Daktronics for help on resolving this issue.

“MAJOR LEVEL FAULT”: If this were to light up, contact Vortek for help.

“LOW LEVEL FAULT”: Indicates one of the two hoists is approximately 2.0° out of the level.

“EMERGENCY STOP”: Indicates the E-Stop button was pressed.
