Functions of the keys
6.1.
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.
6.2.
Start key
The motor can be started in
MANUAL
operating mode by actuating this button. If the motor needs to be pre-
heated, 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.
6.3.
LED Test button
The functioning of all LEDs of the automatic system can be tested by this button. To control other signal
lights of the switchgear during the lamp test, a relay can be parameterised to this function.
6.4.
Alarm Off button
An actuation pulse from this key can be used to cancel the acoustic signal issued by an alarm. The mes-
sage 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.
