Alarm, error, and system messages

Safety-relevant monitoring operations must operate correctly both with and without sway
control and be fail-safe.

Following error monitoring

Trolley and hoist
The following error monitoring system for trolley and hoist can be activated for the positioning
(POS) and semi-automatic (SAM) modes.
The following error monitoring system responds if the deviation between the current position
and the delayed output position is greater than the permitted value. When it responds, the
trolley or hoist decelerates to the stationary state. If sway control is activated, the trolley stops
with sway control. In SAM mode, both trolley and hoist are decelerated. For travel to
recommence, either a switch must be made to manual mode (MAN) or one of the control bits
RELEASE or TRAVEL must be reset. This is always necessary for hoist and trolley in SAM
mode.
● Current position:
– Hoist: rS_Act_HO
– Trolley: rS_Act_TR
● Delayed output position:
The delayed position can be traced in SIMOCRANE CeCOMM using the variable recording
function:
– Selection 12 "Axis.delay.section"
This value ensures that the influence of the sway control system is taken into account by the
following error monitoring function.
● Permitted deviation:
The permitted deviation can be set in the following parameters:
– P161 (trolley)
– P164 (hoist)
The following error is not monitored if the parameters are set to zero.
The following error messages are output if the permitted deviation is exceeded.
– E41 (trolley)
– E42 (hoist)
