The LED in the display field flashes green if Run mode is switched on after entry.
In Run mode, the hand-held transmitter can be used like a cable-connected con-
trol pendant (see figure in section 5.1). For every motion axis of the crane (hoist,
cross travel, long travel) a pair of self-resetting keys is available.
Each of the keys that are arranged next to each other controls one movement
direction.
Key actuation is stepless after the switch-on threshold to enable control of
switched or speed-controlled drives, depending on the design of the crane control
system.
If both directions of are pressed at the same time, the movement is stopped. To
restart the movement, both keys must first return to the rest position.
The STOP key identified in red results in a STOP command which stops the
movements of hoist, cross travel and long travel at the same time and triggers an
emergency-stop in the crane control system.
To avoid danger, the crane operator can immediately stop all movements by
means of the STOP key. The braking process caused by an EMERGENCY stop
can result in load sway.
The STOP key is also intended to be used for switching the radio-controlled crane
into a safe status. This method is to be used when interrupting work and for start-
ing additional functions of the hand-held transmitter for displaying information and
servicing purposes.
When STOP has been actuated, crane operation can only be re-activated by en-
tering the electronic On key.
To obtain increased safety, the STOP key is of two-stage design. For entry of the
On key, both switches must be actuated for a successful check of the function.
