16.8 EDM: 1 external relay at X1/2 with SIL1
Precondition: 1 relay, 1 control and 1 relay output, 1 control input, contact NO:
Parameter Setting Description
„Switch Mode REL1“ 0
REL1 to detect
overspeed
„Switch Mode OUT2“ 9 OUT2 to generate clock signal
„Read Back OUT“ 16 Inversion (connection to X1/2 via NO contact)
„IN3 Function“ 22 Adaption to REL1 (overspeed)
„IN3 Config“ 14 Adaption to clock output OUT2 (via X1/2 contact)
„Input Mode 2“ 2 4 single control inputs for free use
„Read Back Delay“ 0,100 Delay 100 ms to obviate double contact bouncing
„Output Mode“ 0 Inverse configuration
Function:
With normal operation speed the relay output X1 is closed, the external relay
therefore is energized. Upon overspeed the relay output X1 is open and the remote
relay will drop. The forcibly guided aux. contact is closed, when the relay output X1
is energized and the clock signal is conducted to the input.
Under error condition the SMCx monitor will open the relay output X1, the remote
relay will be de-energized, which will signal “overspeed”. With errors occurring
under normal operating speed, the unit will take an error state which signals
“overspeed” again (Safety Integrity Level = 1).
The main contacts can be used as opener or closer depending on the application.
