Fault causes Description
SIL
Thermal fault Motor protection tripped
Torque fault Torque fault in directions OPEN and/or CLOSE
Fault position feed- Current position feedback is outside permissible range.
back
Phase failure One phase of power supply is missing.
Controls are not supplied with mains voltage
Phase sequence The phase conductors L1, L2 and L3 are connected in the wrong sequence.
fault
Power supply failure The safety-related part of controls is without power supply.
Temperature fault Temperature within actuator controls housing too high.
Failure of heating system for ambient temperatures below 25 °C
Failure of actuator Actuator of valve locked
monitoring
Fault in redundant Both signals Safe ESDa and Safe ESDb are not simultaneously on the same level.

The Safe STOP OPEN and Safe STOP CLOSE inputs are two independent inputs
with independent functions:
If Safe STOP OPEN = low level, the safety function inhibits operation in direction
OPEN (exception ESD OPEN)
If Safe STOP CLOSE = low level, the safety function inhibits operation in direc-
tion CLOSE (exception ESD CLOSE)
Permissible input voltage range:
High level: 15 30 V DC
Low level: max. 5 V DC
Signal behaviour of
SIL ready
SIL ready/ Absence of fault to be detected by diagnostics:
NO (NO contact) output = closed
NC (NC contact) output = open
SIL failure/ Presence of fault to be detected by diagnostics:
NO (NO contact) output = open
NC (NC contact) output = closed

refer to chapter <Indications>.
Installation and commissioning must be recorded and a final installation and
commissioning report must be issued.
