Setting:
0.5 s
Proprieties:
Sys, CFG
Description:
It defines the waiting time for the check back signal to go back to its normal working state in the case of the
change of state without the suitable control for change.
The Control Unit monitors the check back signal continuously. If it changes without the corresponding on/off
control, it will wait until for it to go back to the normal state during the maximum time set on P211.
If after having confirmed the setting of the stop control the Control Unit identifies the change of state of the check
back signal without the suitable on control, an error will be generated and the control unit will send out a signal
through the status led and message “E0080” on the HMI.
If after having confirmed the setting of the stop control the Control Unit identifies the change of state of the check
back signal without the suitable on control, an error will be generated and the control unit will send out a signal
through the status led and message “E0081” on the HMI.
