Note (A): Connect mutable safety device to S11/S12 and S13/S14. Connect non-mutable safety device to S21/S22 and S23/S24.
Signals between redundant safety device inputs S11 to S14 or S21 to S24 must be applied within a max. time of 2,5 s.
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. Unused safety device inputs must be connected to power and to the test output: S21 and S23 to
(dc-); S22 and S24 to 58 (refer to Chapter "Test input").
Modes 50 to 59 (only): 1 non-mutable and 1 mutable safety device AND safety devices with test input: the mutable safety
device needs to be activated during the muting sequence.
Note (C): Bi-directional muting with 4 SM muting sensors (example 1B): connect SM1b and SM2b as shown in parallel to SM1a and SM2a.
Note (D): Sensors contact type: this can be voltage free dry contacts or static outputs. When using sensors with static outputs, use 1 PNP and
1 NPN sensor to allow cross fault detection between the input channels.
Note (E): 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.

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. In the case of 2 pairs of muting sensors at
least one of each parallel sensor (SM1a or SM1b, SM2a or SM2b) must remain activated.
• The de-activation of the first muting sensor SM1 or SM2 will stop the muting sequence (only the falling signal edge is taken
into account). In the case of 2 pairs of muting sensors, the de-activation of the first muting sensor group (SM1a / SM1b or
SM2a / SM2b) will stop the muting sequence.
• 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 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 non mutable safety device leads to the de-energisation of the safety relay outputs of the module).
