Requirements
EN IEC 61496-1:
2004
A.5.1 Start Interlock: The start interlock shall prevent the OSSD(s) going to the ON-
state 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 inter-
lock is manually reset. However, it shall not be possible to reset the restart interlock
whilst the sensing device is actuated.
EN 954-1: 1996
5.4 Manual reset
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_Star-
tReset, 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 the PES is started the first time.
