Acceleration Delay Time
This function uses to set the time interval between acceleration relay (i.e. conduction-
delayed time of acceleration relay). It is suitable for accelerative operation only in order to
prevent the cranes directly runs to highest speed to damage the motor.
Interlock Delay Time
“Interlock Delay Time” is delay time between 2 opposite pushbuttons are being press one
after another. i.e.: while crane is moving one direction (forward), moving opposite direction
(backward) immediately would be dangerous specially when crane is hooking up the heavy
object. The object may sway if crane does not completely stop before moving into opposite
