Application Example Of Graphic Simulation - Reer MOSAIC M1 Installation And Use Manual

Application example of graphic simulation

The following example refers to the use of a press located inside a safety area. The
motor of the press can only be started when two conditions are simultaneously true:
the safety area gate is closed and the command to start the motor is sent. The
motor will start two seconds after the start signal is sent.
Diagram
In the diagram the input elements are the safety area gate and the motor start
command. These two signals are used as the input for an AND logic operator the
result of which will be delayed by two seconds by a retarder block. The delayed
signal will then energise the relay which will, in turn, allow the press motor to be
started.

Stimuli file
The stimuli file provide the closure of the gate when 2000 ms have elapsed (signal
set to LL1) and the start command sent by the operator when 3000 ms have elapsed
(signal set to LL1).
