During commissioning (LIMAX33 CP-00 is in Teach mode
11.1) the system fulfils the safety functions listed in
the table below:

SIL3 Same as in normal mode
Overspeed teach
(pre-tripping)
Additional function,
no norm reference
SIL3 Protection in teach mode. Substitute for ETSL, which is
not carried out in tach mode. OC opens if speed
exceeds pre-tripping speed teach. “Pre-tripping speed
teach” is a fixed configuration parameter
14.1. This
safety function is reset (and therefore OC closes) in
case standstill is reached and hold for 1s.
Overspeed teach
(final-tripping)
Additional function,
no norm reference
No
SIL
Protection in teach mode. eSGC opens additionally to
the OC if the speed exceeds final-tripping speed
teach. Final-tripping speed teach is a fixed configura-
tion parameter
After tripping of this safety function, eSGC is kept open
even after stand still. This state is stored in a non-
volatile way: eSGC will also remain open after a pow-
er cycle. This state is cleared by manual reset by RESET
(by CANopen).
Working platform
EN81-20 §5.2.6.4.3.1 b.)
SIL 3 Same as in normal mode
No door bridging and no UCM are active in teach mode.
SR1 and SR2 are always open in teach mode
