Requirements
EN IEC
A.5.1 Start Interlock: The start interlock shall prevent the OSSD(s) going to the ON-state
61496-1:2004
when the electrical supply is switched on, or is interrupted and restored.
A.5.2: A failure of the start interlock which causes it to go to, or remain in a permanent ON-
state shall cause the ESPE to go to, or to remain in the lock-out condition.
A.6.1 Restart interlock: ... The interlock condition shall continue until the restart interlock is
manually reset. However, it shall not be possible to reset the restart interlock whilst the
sensing device is actuated.

ISO 12100-2:2003
4.11.4: Restart following power failure/spontaneous restart
This function block is a safety-related function block for monitoring electro-sensitive protective
equipment (ESPE). The function is identical to SF_EmergencyStop. The S_ESPE_Out output
signal is set to FALSE as soon as the S_ESPE_In input is set to FALSE. The S_ESPE_Out
output signal is set to TRUE only if the S_ESPE_In input is set to TRUE and a reset occurs. The
enable reset depends on the defined S_StartReset, S_AutoReset, and Reset inputs.
If S_AutoReset = TRUE, acknowledgment is automatic.
If S_AutoReset = FALSE, a rising trigger at the Reset input must be used to acknowledge the
enable.
If S_StartReset = TRUE, acknowledgment is automatic if the PES is started for the first time.
If S_StartReset = FALSE, a rising trigger at the Reset input must be used to acknowledge the
enable.
The S_StartReset and S_AutoReset inputs shall only be activated if it is ensured, that no haz-
ardous situation can occur when the PES is started.
The ESPE must be selected in respect of the product standards EN IEC 61496-1, -2 and -3 and
the required categories according EN 954-1.
