If on the rising edge of the reverse command the stop command is TRUE the lift moves to the next floor.
This command can ONLY be executed if the Self Study sequence has been successfully completed, and the
SelfStudyOk parameter is set to TRUE.
3.3.8
Forward command
The forward command has four operating modes:
Case
1
Maintenance input closed (enable)
2
Maintenance input open (disable)
Zero cycle not done (ZeroFound = FALSE)
Lift car stopped NOT at floor
3
Maintenance input open (disable)
Zero cycle not done (ZeroFound = FALSE)
Lift car stopped at top floor 0
4
Maintenance input open (disable)
Zero cycle done (ZeroFound = TRUE)
Forward command with Maintenance input = enable
If the maintenance input is closed (enable) when the forward command is sent the control system
acts as if the JogFwd command had been set.
Forward command before zero cycle
If the forward command is sent before the incremental encoder and floor counter have been
initialised, a zero cycle is executed.
This command can ONLY be executed if the Self Study sequence has been successfully completed,
and the SelfStudyOk parameter is set to TRUE.
Forward command after zero cycle
The forward command following execution of the zero cycle, indicated by the ZeroFound= TRUE
output, functions as follows:
On the rising edge of the command the lift starts moving towards the top floor.
•
The following events may occur while the lift car is moving:
-
-
-
If on the rising edge of the forward command the stop command is TRUE the lift moves to the next
floor.
This command can ONLY be executed if the Self Study sequence has been successfully completed,
and the SelfStudyOk parameter is set to TRUE.
3.3.9
Stop command
The stop command is active after the zero cycle (ZeroFound = TRUE), and only interacts with the forward
and reverse commands.
For more information please read the sections on the forward and reverse commands.
ADL300-EPCv2- User Guide
Cause
Nothing happens: the lift reaches the top floor executing the normal deceleration
ramp as set.
Removal of the forward command: the lift stops at any point after executing the
normal set deceleration ramp.
The stop command becomes TRUE causing the lift to stop at the first possible floor.
