7. The process according to claim 1, characterized in that the display of several pages is performed by displaying successively said pages on the screen of the terminal manually from the keyboard, or automatically according to a set display time.
8. The process according to claim 2, characterized in that it also comprises, after the automatic display of the composite multimedia message, the steps of:
a) manually invalidating, from the terminal keyboard, the display of the composite multimedia message.
b) automatically layinz out the composite multimedia message on at least one page having a second format different than the first format;
c) automatically displaying the composite multimedia message on the screen of the terminal.
9. The process according to claim 8, characterized in that the invalidation is performed (n) times, (n) being a number of available different formats enabling layout of the composite multimedia message to be performed.
10. The process according to claim 9, characterized in that (n) is an integer between one and ten.
11. The process according to claim 2, characterized in that the selected initial multimedia message comprises a digital image.
12. The process according to claim 2, characterized in that the selected initial multimedia message comprises a digital image and at least one text message.
13. The process according to claim 2, characterized in that the selected initial multimedia message comprises a digital image, at least one text message and audio data.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A protective device for the safety-related shutdown of an electrical unit, comprising:
a first input for receiving a switch-off signal;
a second input for receiving a switch-on signal in the form of a switch-on pulse;
an output for driving the electrical unit; and
a pulse processing device for setting the protective device to an activation state, in which it is switchable on when the switch-off signal is not applied, for a predetermined period of time from reception of the switch-on pulse, wherein
the pulse processing device includes a timing element which provides an acknowledgment command for maintaining the activation state for a predetermined time after the switch-on pulse.
2. The protective device as claimed in claim 1, wherein the switch-on signal originates from an on pushbutton.
3. The protective device as claimed in claim 1, wherein the switch-off signal originates from a latchable emergency-stop pushbutton.
4. The protective device as claimed in claim 1, wherein the electrical unit is an actuator.
5. The protective device as claimed in claim 1, wherein the inputs and outputs include a plurality of channels.
6. The protective device as claimed in claim 1, wherein at least one of the falling edge and both edges of the switch-on pulse are evaluated by the pulse processing device for setting the protective device to the activation state.
7. The protective device as claimed in claim 1, wherein the predetermined period of time for the activation state corresponds to at least one of the activation time of the electrical unit and a further protective device.
8. The protective device as claimed in claim 1, wherein the electrical unit is a contactor.
9. A protective system having a plurality of protective devices as claimed in claim 1, connected in cascade fashion, a first input of a second of the plurality of protective devices being driven by the output of a first of the plurality of protective devices.
10. The protective system as claimed in claim 9, wherein the inputs of the plurality of protective devices are connected to a common on pushbutton.
11. A method for safety-related switching of an electrical unit, the method comprising:
receiving a switch-off signal;
switching the electrical unit off;
receiving a switch-on signal in the form of a switch-on pulse;
switching the electrical unit on, the electrical unit being switchable on for a predeterminable period of time after reception of the switch-on pulse; and
providing an acknowledgement command for maintaining an on state of the electrical unit for a predetermined time after the switch-on pulse is received, wherein at least one of the falling edge and both edges of the switch-on pulse are evaluated in order to start the predeterminable period of time in which the electrical unit is switchable on.
