The operation of the automatic system is simple and uncomplicated as it is carried out via the usual
buttons
– without menu guidance – as for the automatic system it replaces.
6.
Displays and keys
The operating modes are selected by four keys. 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.
6.1.
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.
6.2.
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.
6.3.
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. Af-
ter the cause of the error has been eliminated, the LED display is deleted by actuating the button
again.
