S_EDM_Out output

Output signal for controlling the connected contactors. If all the conditions have been satisfied, the S_EDM_Out output reflects the signal state at the S_OutControl input.

Data type: SAFEBOOL

NOTE:

As the enable signal is present at the S_EDM_Out output, this output is also referred to as the enable output.

Connection: Connect this output to the coils of the contactors to be monitored.

The enable signal may only control the process directly if this does not adversely affect the safety-related function.

WARNING
	UNINTENDED EQUIPMENT OPERATION Verify that the enable signal only controls the process directly if this does not adversely affect the safety-related function. Validate the overall safety-related function, including the start-up behavior of the process, and thoroughly test the application. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Value	Description
SAFETRUE	The following conditions must be met: The function block has been activated (input Activate = TRUE) and the control signal at the S_OutControl input is SAFETRUE and the connected contactors are functioning correctly (initial state and switching behavior OK) and no start-up inhibit is active (setting made with S_StartReset) and the function block has not detected an error.
SAFEFALSE	This may be due to one of the following reasons: The function block is not activated (input Activate = FALSE) or the control signal at the S_OutControl input is SAFEFALSE or one of the connected contactors is not functioning correctly (initial state or switching behavior not OK) or a start-up inhibit is active (setting made with S_StartReset) or the function block has detected an error.

Precise details of the behavior of the S_EDM_Out output in relation to the start-up inhibit are given in the following table:

Formal parameter	Value	Action	Start-up inhibit	Reset	Enable output
S_StartReset	SAFETRUE	After function block activation/Safety Logic Controller start-up, the start-up inhibit is ...	not active	No action is required at Reset, ...	- to switch the enable output S_EDM_Out to SAFETRUE if there is a valid input signal combination. - to exit the start-up inhibit.
