11.1.5.2
Test mode, sub-mode ETSL-UP
Test mode, sub-mode ETSL-UP can be entered by CANopen command to change the sub-mode to “ETSL-UP”.
This can be only done if the device is in test mode.
The behavior of safety function deceleration control (ETSL) is different in this sub-mode:
When moving up, distance “s” in the ETSL-formula is not calculated as the distance of the actual posi-
tion to the position of the upper reference position minus upper ETSL- offset, but as the distance of the
actual position to the “middle of the shaft”. For details see
The behavior of all other safety functions, including the behavior of ETSL when moving down, is identi-
cal to normal mode.
The CANopen command to change the sub-mode to ETSL-UP (while the device is in test mode) is only
accepted if the actual position is below the “middle of the shaft”.
Concerning calculation of position of “middle of the shaft” refer to Table 14.
11.1.5.3
Test mode, sub-mode ETSL-DOWN
Test mode, sub-mode ETSL-DOWN can be entered by CANopen command to change the sub-mode to “ETSL-
DOWN”. This can only be done if the device is in test mode.
The behavior of safety function deceleration control (ETSL) is different in this sub-mode:
When moving down, distance “s” in the ETSL-formula is not calculated as the distance of the actual po-
sition to the position of the lower reference position plus lower ETSL- offset, but as the distance of the
actual position to the “middle of the shaft”. For details see
The behavior of all other safety functions, including the behavior of ETSL when moving up, is identical
to normal mode.
The CANopen command to change the sub-mode to ETSL-DOWN (while the device is in test mode) is
only accepted if the actual position is above the “middle of the shaft”.
Concerning calculation of position of “middle of the shaft” refer to Table 14.
11.1.6
Test Mode, Sub Mode “Pre-Trig”
Sub mode “pre-trig” can be entered by CANopen command to change the sub-mode to “pre-trig”. This can
only be done, if the device is already the test mode. The behavior of safety function pre-triggered stopping sys-
tem is different in this mode:
In normal mode the pre-triggered stopping system trips in case of EN81-21-state (
13.2.6.1) and if
the actual position is higher than the upper resp. lower than the lower stopping limit.
In sub-mode pre-trig, the safety function trips if the actual position is higher than the upper resp. lower
than the lower stopping limit – no matter if there is EN81-21-state or not.
But the behavior of the inspection limit switches depends on the EN81-21-state also in sub-mode pre-trig, (same
behavior like in normal mode). So, if there is sub-mode pre-trig and no EN81-21-state, the pre-triggered stop-
ping system is active, but the inspection limit switches are not active. That means, in this situation the pre-
triggered stopping system can be tested:
1.
It is possible to send the lift towards the shaft end from outside of the lift with activated the pre-triggered
stopping system
2.
when approaching the shaft ends, no inspection limit switches stop the car
When approaching the shaft ends, pre-triggered stopping system will trip, because the inspection limit switches
will not prevent tripping of pre-triggered stopping system.
After tripping of pre-triggered stopping system, a RESET is necessary. After RESET the safety function will be reset
and LIMAX33 CP-00 will restart in normal mode.
But this mode can also be left explicitly by the transition to normal mode, initiated by CANopen command.
