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.
OVER SELECT FAULT: Lights up when more than 4 hoists are selected to run at one time and will pre-
vent any hoists from operating. Deselecting hoists will turn this indicator off and enable the hoists to
operate once more.
VOLTAGE/PHASE FAULT: Lights up when voltage is Under or Over by 10% of specified settings. (Set to
specified voltage per installation, either 208v or 480v). This light also lights up when phase reversal is
detected and will prevent the system from operating.
