Operating manual V2.0

6.1.2 Testing the trip time monitoring

The lift must be in normal operation. For testing ,the menu item "Technical check"->"Trip
time" must be started.
In the display of the HSE the actual floor is displayed. In the 2nd line the current controller
state is displayed (normally "Standstill", "Moving" or "Arrival").
If the lift is in "Standstill" state, the controller sets a car call to any other floor. When starting
the trip to this floor the parameter "Triptime[s]" is automatically set to 2 seconds.
After expiration of the trip time an emergency stop is carried out and the new state "Trip
time" is displayed.
Exiting the menu item with ESC, the parameter "Triptime [s]" will be set back to the old value
and the error will be deleted.

6.1.3 Testing the final limit switches

The lift must be in normal operation. For testing ,the menu item "Technical check"-
>"Limitswitch top" or "Limitswitch bot." must be started.
In the display of the HSE the actual floor is displayed. In the 2nd line the current controller
state is displayed (normally "Standstill", "Moving" or "Arrival"). In 3rd line the actual position
in mm is displayed, while the 4th line shows the differenc between floor level of the actual
floor and the actual position.
The lift controller sets itself a call to the top or bottom floor. If the lift is already in the top or
bottom floor the lift first sets a call to any other floor, before starting the trip to the top or
bottom floor.
When arriving the top or bottom floor the lift will slow down like in normal operation, but then
will go up to the final limit switch with arrival speed v0.
If the lift hits the final limit switch, the new state "SL on trip", followed by "SL error" and, after
a few seconds, "Limit sw.".
In 4th line it is displayd now the exact triggering position of the final limit switch (if the lift uses
a digital positioning system like AWG or encoder).
If the lift is then manually lowered when testing the upper limit switch so far that the top limit
is switched on again, then a homing to the bottom landing takes place, if it is a hydraulic lift.
When exiting the limit switch test menu with ESC, no return to normal operation takes
place (starting from software version 1.29i), because that partially led to irritation at the
test sequence. Here then a reset is required (menu item "Reset HSE")
If the lift controller on reaching the final limit switch does not display "Limit sw." after a
few seconds, then usually the parameter "Top limit" or "Bot.limit" is set incorrectly.
