Changing Values in Set Mode
D000030110 d – E650 Series 3 (ZMD400AT/CT, ZFD400AT/CT) – User Manual
In set mode, some values (date and time, identification numbers and bat-
tery hours counter) can be changed with the aid of the reset key and dis-
play keys, without the use of auxiliary aids such as hand-held terminal or
laptop.
Procedure:
1.
Remove the front door seal.
2.
Open the front door, so that the reset key is accessible.
3.
Press the "up" or "down" display key briefly. The display changes from
operating display to display check.
4.
Press the reset key. The display changes to the service menu with the
first menu item.
5.
Press the "down" display key as many times briefly, until the menu item
"Set mode" (SEt) is displayed.
6.
Press the "up" or "down" display key for longer (at least 2 seconds),
until the first value for setting is displayed.
7.
Select the value to be changed with the "up" or "down" display key.
8.
Press the reset key. The first digit of the value to be changed flashes.
9.
Change the digit by pressing the "up" (increase) or "down" (decrease)
display key as required.
10. Press the reset key. The next digit of the value to be changed flashes,
if it was not previously the last digit. Otherwise all digits flash together.
11. Repeat steps 9 and 10 for all digits of the value to be changed, until all
digits of the changed value flash together.
12. Press the reset key to confirm the new value (the value set can be re-
jected and the previous value retained by pressing the "up" or "down"
display key). After pressing the reset key the new value is given a plau-
sibility test and stored if the test result is positive. The next value for
setting is displayed. In the event of an error (e.g. invalid date or time)
all digits continue flashing and the input must be repeated.
13. If required, further values can be changed as described in steps 7 to 12.
14. If you press the "up" and "down" display keys simultaneously, the
operating display appears again.
15. Close the front door.
16. Re-seal the front door.
