When starting the menu item "Technical check" -> "Safety gear" first the floor where the
safety gear should be triggered must be entered. With the cursor keys it is also possible to
select a reduced speed for safety gear test (only HSE software version 1.38b or newer). Pre-
setting is nominal speed v3, but reduced speeds v1 or v2 can be selected.
The lift then moves towards to the floor which had been set. Between 300 and 500 mm
before reaching the defined floor (depending on the lift speed) the safety gear is triggered, so
that the lift within functioning safety gear stops approximately at flush level of the selected
floor (advantageous if, for example, test weights must be unloaded).
Within the control display of HSE / handheld terminal the trigger position is displayed in the
3rd line and in the 4th line the way in mm, that was laid back after the safety gear was
triggered (only with digital positioning like AWG or encoder).

6.1.6 Testing the motor brake

The automated testing of the motor brake is only possible if the brake is controlled via a relay
of the main board HSE.
The testing of the individual brake shoes is only possible if they are connected via separate
relays of the HSE.
The outputs for switching the brake have to be programmed as follows:

6.1.6.1 No brake opening at start
When starting the menu item "Brake not open" the lift controller sets a car call in the top or
bottom floor (depending on which floor is further away from the current car position, i.e.,
depending on where the car is currently located, the brake test is performed in upward or
downward direction).
When starting, the mechanical brake is not actuated, and it can be checked whether the lift
moves further even with closed brake. Any existing feedback contacts of the brake are to be
ignored by the lift controller.
The LCD display will show how far the lift has possibly moved with closed brake.
