SAR 16.2 Control unit: electronic (MWG)
Description/cause
Operation mode EMERGENCY is active (EMER-
GENCY signal was sent).
0 V are applied at the EMERGENCY input.
The actuator is controlled via the I/O interface (par-
allel).
Manual operation is activated.
Fieldbus connection available, however no process
data transmission by the master.
A local STOP is active.
Push button STOP of local controls is operated.
An interlock is active.
By-pass function is interlocked.
Partial Valve Stroke Test (PVST) is active.
SIL function is active

only), at 115 V AC also control inputs OPEN, STOP, CLOSE
Automatic reset fuse as short-circuit protection for external 24 V DC supply for
customer (see wiring diagram)
Remedy
Detect cause for EMERGENCY signal.
Verify failure source.
Apply +24 V DC at EMERGENCY input.
Check I/O interface.
Start motor operation.
Verify master configuration
Release push button STOP.
Check interlock signal.
Check states of main and by-pass valve.
Wait until PVST function is complete.
