Notes:
• Maximum coïncidence time between activation of muting sensors SM1 / SM2: 10 s (only the raising signal edge is taken into
account).
• Muting sensors can be activated in any order (SM1 then SM2 or SM2 then SM1).
• All muting sensors SM1 and SM2 must remain activated during a muting sequence.
• The de-activation of the first muting sensor SM1 or SM2 will stop the muting sequence (only the falling signal edge is taking
into account).
• tmax.: max. muting time programmable with the internal selector "B".
• The activation of only one sensor SM is ignored (see Q).
• The activation of the mutable safety device is not necessary during a muting sequence (except for modes 50 to 59) (see R).
• Muting sensors SM1 and SM2 must be inactive before starting a new muting sequence (see S).
• The restart push-button must be pushed AND released within 3 s to start the module (see T).
• Activating the not mutable safety device leads to the de-energisation of the safety relay output of the module.
In order to start a muting sequence, the muting sensors SM1 and SM2 must be activated within a time frame of maximum 10 s.
The muting sequence is stopped after de-activating the first of the two muting sensors SM1 or SM2.
In any case, the muting sequence will be interrupted after the maximum selected muting time has elapsed. If an object remains
accidentally in the detection field of the safety device, an external temporary manual muting (customer supplied) may be used to
evacuate the detection field (see chapter "Temporary Manual Muting").

Note (A):
Signals between redundant safety device inputs S11 to S14 or S21 to S24 must be applied within a max. time of 2,5 s.
Connect mutable safety device to S11/S12 and S13/S14. Connect non-mutable safety device to S21/S22 and S23/S24.
Modes 20 to 39: muting using safety devices without test input: unused safety device inputs must be connected to power:
S21 and S23 to (dc-), S22 and S24 to (dc+).
Note (B):
Modes 50 to 69: muting using safety devices with test input: terminal 58 is used as test output that must be connected to the
test input of each safety device (refer to chapter "Test input" for details).
Note (C):
Sensors contact type: safety switch contacts are preferred for press applications.
Note (D):
External contactors: when external contactors are used, connect one normally closed contact of each contactor (or the normally
closed contact of the FF-SRE extension module) in series into the combined restart loop and External Device Monitoring (EDM)
loop S43/S44. Install arc suppressors across the coils of external safety relays.
