IMPORTANT NOTICES
• The FF-SRS5935 will only restart after the two input channels have been opened and then closed (an
activation). There is no timing limitation between the activations of these two safety inputs.
• In the manual start mode, closing the start push button will immediately close the normally open contacts of
the safety control module and initiate a machine start cycle. The push button must be released before the
next start cycle is allowed. This will prevent automatic restart in case the push button is broken in the
closed position.
• If a safety control module is used in an automatic start mode, position the S2 switch to the "automatic start"
mode. In addition, the start push button must be replaced by a jumper (between terminals S33/S34). If
external safety relay monitoring is necessary, connect one contact of each relay required to be monitored,
in series between S33/S34.
