Functions of the keys
7.1.
Operating mode keys
The operating modes are selected via four keys
– see illustration above. The selected operating mode
is displayed by LEDs. The keys can be locked via an input (e.g. via connection of an external key-
operated control switch), so that the unauthorised or random change of a defined operating mode is
prevented. The operating modes described below can be selected using the keys.
7.2.
Start key
The motor can be started in
MANUAL
operating mode by actuating this button. If the motor needs to be
preheated, the pre-heating device must be externally controlled. Actuating this key is ineffective when
the machine is running or also in any other selected operating mode.
7.3.
LED Test button
The functioning of all LEDs of the automatic system can be tested by this button. To control other sig-
nal lights of the switchgear during the lamp test, a relay can be parameterised to this function.
7.4.
Alarm Off button
An actuation pulse from this key can be used to cancel the acoustic signal issued by an alarm. The
message continues to flash. After a second confirmation, it changes over to continuous lighting. After
the cause of the error has been eliminated, the LED display is deleted by actuating the button again.
