Bytes 3 and 4: Actual position
Byte 3 = high byte, byte 4 = low byte.
If a position transmitter (potentiometer, RWG, EWG, or MWG) is installed in the
actuator, bytes 3 and 4 are used to transmit the current actuator position. The value
is transmitted in per mil (value: 0

Value Description
1 Motor protection tripped
0 No signal
1
When connecting to a 3-ph AC system and with in-
ternal 24 V DC supply of the electronics: Phase 2 is
missing.
When connecting to a 3-ph or 1-ph AC system and
with external 24 V DC supply of the electronics: One
of the phases L1, L2 or L3 is missing.
0 All phases are available.
1 Selector switch is in position REMOTE.
0 Selector switch is not in position REMOTE.
1 Selector switch is in position LOCAL.
0 Selector switch is not in position LOCAL.
1 Limit switch operated in end position OPEN
0 No signal
1 Limit switch operated in end position CLOSED
0 No signal
1 Torque switch operated in direction OPEN.
0 No signal
1 Torque switch operated in direction CLOSE.
0 No signal
1,000).
Value Description
1 Collective signal 04:
Contains the result of a disjunction (OR-operation) of all
bits comprised in bytes 13 and 14 (Not ready REMOTE
1 and Not ready REMOTE 2).
The actuator cannot be operated from REMOTE.
The actuator can only be operated via the local controls.
0 In bytes 13 and 14, no signals are active (all bits are set
to 0).
1 Collective signal 02:
Contains the result of a disjunction (OR-operation) of all
bits of bytes 17 to 20 (Warning 1 to Warning 4).
0 In bytes 17 and 20, no warnings are active (all bits are
set to 0).
1 Collective signal 03:
Contains the result of a disjunction (OR-operation) of all
bits of bytes 15 and 16 (Fault 1 and Fault 2).
The actuator cannot be operated.
0 In bytes 15 and 16, no faults are active (all bits are set to
0).
