Locking the "HAND" key
(As of SW revision 007)
The "HAND" key function can be configured with
step 213 in the Configuration menu when the display is

if the "HAND" key is pressed inadvertently.
The following settings are possible:
1. Lock
"OFF"

Pressing the "HAND" key while the display is in the
home position starts a manual heating process. The
heatsealing band is heated for as long as the
"HAND" key remains pressed.
2. Lock

The "HAND" key is locked when the display is in the
home position, in other words it has no function.

It is possible to disable all changes to values/
parameters in the Configuration menu. This prevents
the controller configuration from being tampered with

The Configuration menu can be locked or unlocked by
pressing the "MENU" key for 2seconds while the
power-up message is displayed (after switching on the
controller,
ª
section 10.2.1 "Power-up message" on
page 27). The display then shows a message
confirming that the lock function is active for 2seconds
before returning to the home position.
The same message is also displayed for 5seconds
when you open the Configuration menu to indicate that
this menu is locked.
You can still display all steps, values and
parameters even if the Configuration menu is
locked. You are no longer allowed to enter or
change values, however.
The Configuration menu remains locked until the lock
function is canceled again. To do so, repeat the above
procedure (press the "MENU" key for 2seconds while
