Examples And Special Notes On Implementation - Festo CAMC-G-S3 Manual

2 Product description of safety module CAMC-G-S3
When the device is delivered, the single-channel input DIN49 is preset to the sensor type
"Terminate safety function / Restart" and, as "Restart" is switched to the safety functions
"STO" and "SBC".
On each rising edge (0 V -> 24 V) at DIN49, the signal LIN_D49_RISING_EDGE supplies a
short switching pulse of a length of 2 ms, via which the safety functions can be reset.
Time delays from LIN_D49_RISING_EDGE
VIN_xxx_CSF up to termination of the safety function
Tab. 2.70 Runtime performance, restart
Please note
Please check whether a single channel control input for the restart is permitted in your
application and whether it is level-controlled or edge-controlled. Use ...
– LIN_D49, if a level-controlled reset is permitted,
– LIN_D49_RISING_EDGE, if an edge-controlled reset is required,
– in all other cases, use one of the two-channel inputs LIN_D40 to LIN_D43.
Please note
Please check whether the risk analysis for the machine has created additional require­
ments for the control of the restart and for the diagnostics of the corresponding control
input, e.g. manual, edge-controlled resetting through accessible protective devices.

Examples and special notes on implementation

Restart after termination of STO
Fig. 2.29 shows the structure for the STO safety function. During operation, STO can be requested via
VIN_STO_RSF. The request of the safety function STO causes the driver supply in the motor controller
to switch off. To switch the drive back on again after a STO request, the request must have been termin­
ated, as described in è Section 2.7.1.
