This alarm will sound if:-
l. A lift stop occus.
2. Air pressure for the braking system falls below a safe operating pressure.
LED Diagnostic Display
Indicates a malfunction in the Safety System, Gives an LED read out which corresponds to a specific limit switch, photo-cell. air pressure switch, etc.
WLH Note: The LED display was covered over with blue plastic after the ride was converted to once person operation, no idea why.
Diagnostic Display Clear (Push Button)
When depressed will reset the LED Display readout. This should not be reset until the problem is identified and rectified.
Air Pressure Gauge
Shows the amount of air presure in the Braking System. Designated markings on the dial display acceptable operating pressure limits
Lap Bars Up (Push Button)
When depressed UNLOCKS the electrically activated locking mechanisms on the lap bars on the trains.
Lap Bars Down (Push Button)
When depressed LOCKS the electrically activated locking mechanisms on the lap bars on the trains.
