and the off-duty time.
During menu run, the following data is displayed:
1. Display of the menu item
2. Adjustable maximum value
3. Value set
7.1.1 Control operation
After long pressing (>1 s) of [MODE], the menu item "CODE" appears. Upon entry of the
password (numerical password, preset to "1234"), you have access to the menu.
As of software version 2.52, the password can be changed by the user.
When switching the voltage for approx. 2 seconds on, the software version will be displayed.
How to change a password:
1. Press Save + Mode
2. Keep keys depressed and switch voltage on
3. Enter current password (factory default: 1234)
4. Save by pressing "Save"
5. Enter new password
6. Save by pressing "Save"
7. The program will change into normal mode
Should an incorrect entry be made in step 4, the control will, after pressing of [SAVE], switch
into the normal mode immediately. To change the password, the user is required to restart
with step 1.
If the newly changed password gets lost, the control can be reset to the original parameters
in the factory.
This, however, will result in loosening all changes made.
For that reason, all changes made to the parameters should always be recorded and
archived.
By pressing [MODE] repeatedly, you can switch from one menu item to the next one. Depen-
ding on the setting selected, non-relevant menu items will be suppressed.
You may browse the menu items into one direction only. It is not possible to switch back to a
previous menu item.
To select the menu item, press [SELECT]. When this item is pressed once, the set value will
be displayed. Another pressing will change the value by +1. By pressing [MODE], the value
will be changed by -1. During setting, the value display is flashing.
Acknowledge the value changed by pressing [SAVE]. As soon as the display stops flashing,
the new value will be saved.
