Check whether the output OUT0 "Enable" has been switched to HIGH (ready for operation), otherwise there is a fault
condition.
Before selecting a measurement program all inputs must be switched to LOW for 30 milliseconds.
Switch the input IN3 "Menu selection" to HIGH
Simultaneously with
Within 40 milliseconds of switching IN3 "Menu selection" the outputs OUT1-3 are switched to HIGH.
After the binary value has been present for a minimum of 40 milliseconds, then switch the input IN3 "Menu selection" to
LOW.
Simultaneously with
After a maximum amount of 40 ms all outputs OUT1-3 are switched to LOW. If the configuration "Measurement internal"
has been selected measurement will start automatically again (provided a valid program has been selected). If the
configuration "Measurement external" has been selected then the operation of the unit it is performed via the PLC.
Example:
Check whether the output OUT0 "Enable" has been switched to HIGH.
All inputs should be on LOW for more than 30 milliseconds.
Switch input IN3 "Menu selection"
and simultaneously the binary values to IN0-2 and IN4-7.
Check after more than 40 milliseconds whether the outputs OUT1-3 have been switched to HIGH.
Switched the input IN3
and the binary value (IN0-2 and IN4-7) to LOW.
Wait the necessary time (refer to the diagram) until the outputs OUT1-3 have switched back to LOW.
Program no.
