Disabling the Configuration menu
It is possible to disable all changes to values/parame-
ters in the Configuration menu. This prevents the con-
troller configuration from being tampered with by unau-
thorized persons.
The Configuration menu can be disabled or enabled by
pressing the "MENU" key for 2.0seconds while the
power-up message is displayed (after switching on the
controller,
section 9.2.1 "Power-up message" on
page 23). The display then shows a message confir-
ming that the disable function is active for 3.0seconds
before returning to the home position.
The same message is also displayed for 5.0seconds
when you open the Configuration menu to indicate that
this menu is disabled.
You can still display all steps, values and
parameters even if the Configuration menu is
disabled. You are no longer allowed to enter or
change values, however.
The Configuration menu remains disabled until the
disable function is canceled again. To do so, repeat the
above procedure (press the "MENU" key for
2.0seconds while the power-up message is displayed).
The display then shows a message confirming that the
disable function has been canceled.
In the factory setting the Configuration menu is not
disabled.

Setting the display brightness
(VF display only)
If the display is in the home position, the brightness of
the VF display (blue) can be set in 4 steps (25%, 50%,
75%, 100%) with the "UP" and "DOWN" keys.
The factory setting is 75%.
The life of the VF display can be prolonged by reducing
the brightness.

Undervoltage detection
Trouble-free operation of the temperature controller is
guaranteed within the line voltage tolerance range spe-
cified in section 5 "Technical data" on page 9.
If a line voltage which is less than the lower limit of the
permissible range occurs, the controller is switched to
a standby mode. No more heatsealing processes take
place and no more measuring impulses are generated.
The display changes to indicate this.
The main menu is displayed again, and operation is
resumed, when the input voltage returns to the speci-
fied tolerance range.
The alarm relay is not switched if an undervoltage con-
dition occurs. The standby mode is indicated by 0…3°C
(corresponds to app. 0V) at the analog output.
Trouble-free operation of the controller is
only guaranteed within the specified input
voltage tolerance range. An external voltage
monitor must be connected to prevent defective
heatseals as a result of low line voltage.
