5. CEM7 CONTROL UNIT INPUTS AND
OUTPUTS
The CEM7 control unit's digital inputs, both those with a specific purpose as well
as those which are programmable, have a debounce time associated (Times table,
parameters 15-24) which requires that the value of the input is stable over a time
interval. Also, all of the CEM7 control unit's inputs can be configured to be active
with contact closed to earth or be inactive with contact closed to earth (Regulations
table parameters 5 to 15).
The status of the CEM7 control unit's inputs and outputs can be monitored from
the Main menu1
.Inputs/Outputs. From that position, a screen displays the
status of the control unit's digital inputs and outputs:
