 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  or delayed switch the binary values to IN0-2 and IN4-7.
 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  or delayed switch back the binary values at IN0-2 and IN4-7 (switch to LOW).
 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.
