3.5.1 Flush correction by keypad of HSE or handheld terminal DSE

This procedure should be especially selected if it is possible to plug in the handheld terminal
on the FVE and operate it from inside the cabin.
After starting the sub-menu item "via terminal" the lift disables the landing calls and opens
the car door.
Using the cursor keys and ENTER, a floor can now be selected. When the lift reaches the
destination floor, the deviation of the car from the flush position is measured. This value is
entered using the arrow keys and pressing the ENTER key, whereby at a too low car
position, a positive ,and at a too high car position, a negative value is entered (also appears
as an indication on the LCD display).
The bottom line also displays the deviation of the car from the currently in the controller
stored level position; this should be as described above as small as possible, otherwise an
accurate level correction is not possible.
The process can be repeated any number of times in any order. A final separate storage is
not necessary here, since the values are stored in non-volatile immediately after each entry.

4. Error diagnosis

4.1 General procedure for troubleshooting

The lift controller software of MLC 8000 includes a comprehensive self-diagnostics. Faults
that have occurred are stored in an error stack and can be accessed via keyboard and LCD
display of the HSE or the hand-held terminal.
However, the HSE can not diagnose all faults clearly. For example, when the photocell is
constantly interrupted, then the lift control can not determine whether the light barrier is
defective or improperly connected or whether the light barrier is actually permanently, e.g. is
interrupted by a person or an object in the door. This aspect must be strictly observed during
troubleshooting.
In inspection mode disorders might be caused by the lift mechanic part. These error
messages are of course also stored in the controller error stack and can lead to
misjudgments in a later troubleshooting. Therefore, the error stack of the controller should be
cleared after maintenance.
At the same time, the integrated real-time clock in the controller should be tested during each
inspection. An incorrectly real-time clock or a discharged watch battery on the HSE lead to
incorrect time stamps in the error stack and can therefore also lead to incorrect conclusions
in troubleshooting.

4.2 LED indicators

The lift controller MLC 8000 has some LEDs, which indicate certain control conditions.
The LEDs of the individual control modules are listed in the Appendix. The main board HSE
has 3 LEDs driven by the software:
