7. Parameters of lift controller

The lift controller MLC 8000 has a large number of parameters by which the controller can be
adapted to various requirements.
All parameters are stored in a nonvolatile memory (EEPROM) of the HSE (ICs U1 and U2 of
the HSE). These memory modules are located in a socket, so they can be replaced easily
and without tools, if the HSE is defective and must be replaced. Therefore the parameters
must not be re-entered while replacing a HSE module.

7.1 Saving parameters

Newly changed parameters are initially stored only in the RAM of the HSE. This means that
after a reset or power down all the changes are lost.
For fixed saving of the parameters in EEPROM, the menu item "Save parameters" must be
started or the storage process can be started by the key command "9↵". The saving process
takes a few seconds and may be carried out while the lift is in normal operation.
By this all changed parameters are generally saved, i.e., it is not possible to save only
individual parameters.

7.2 Parameter backup

All parameters of the lift controller are completely stored in the EEPROM U1.
In the second EEPROM U2, a copy of the parameter set can be stored for backup purposes.
This backup copy can be created by the menu item "Create backup"in the menu "Parameter"
- "Parameter backup" . All parameters of the first EEPROM are identical copied to the second
EEPROM.
If accidentally parameters of the lift controller are changed and saved and the lift isn't working
anymore, then via menu item "Reload Backup" the parameter set can be reloaded from the
backup copy. However, it must be sure that in fact there is a backup in the second EEPROM.
After reloading the backup the parameters need to be saved separately (see above).
After each change of parameters or at the latest after commissioning, a backup of the
parameters should be made.
It is also possible to make a copy of all parameters on a computer with the PC
software "Liftcontrol". See manual of "Liftcontrol"

7.3 Changing parameters

Parameters can be changed using the keyboard or the HSE or with the handheld terminal.
Both the changing and saving of the parameters can be carried out during normal operation
of the lift.
