16.6 EDM: 2 external relays at X4 with SIL3
Precondition: 2 relays, 3 control outputs, 2 control inputs, auxiliary contact NO:
Parameter Setting Description
„Switch Mode OUT1“ 9 OUT1 to generate clock signal
„Switch Mode OUT2“ 0 OUT2 to signal overspeed
„Switch Mode OUT3“ 0 OUT3 to detect overspeed
„Read Back OUT“ 6 Inversion (connection via NO contact)
„IN3 Function“ 18 Adaption to OUT2 (overspeed)
„IN3 Config“ 12 Adaption to clock output OUT1 (via X24/2 contact)
„/IN3 Function“ 19 Adaption to OUT3 (overspeed)
„/IN3 Config“ 13 Adaption to clock output /OUT1 (via X24/3 contact)
„Input Mode 2“ 2 4 single control inputs for free use
„Read Back Delay“ 0,050 Delay 50 ms to obviate contact bouncing
„Output Mode“ 0 Inverse operation
Function:
This application uses two independent outputs /OUT2 and /OUT3 with fully
identical configuration concerning their switching characteristics. The basic
function is similar to the application with one relay. The auxiliary contacts of
both relays are individually connected to a separate input each. The GND lines of
the two relays must be independent one from each other (Safety Integrity Level
= 3).
The main contacts can be used as opener or closer depending on the application.
