Table 3: Byte 5: Device status
Bit Designation
(process representation)
0 Bit: Not ready REMOTE
1 Bit: Warnings
2 Bit: Fault
3 Bit: Maintenance requ.
4 Bit: Out of spec.
5 Bit: Function check
6 Bit: Failure
7 Bit: Device ok
14
Value Description
1 Torque switch operated in direction OPEN.
0 No signal
1 Torque switch operated in direction CLOSE.
0 No signal
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

Byte 5: Device status

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).
1 Collective signal 09:
Indication according to NAMUR recommendation NE 107
Recommendation to perform maintenance.
Contains the result of a disjunction (OR-operation) of all bits of byte 24 (Maintenance
required).
0 In all bits of byte 24, no signals are active (all bits are set to 0).
1 Collective signal 07:
Indication according to NAMUR recommendation NE 107
Actuator is operated outside the normal operation conditions.
Contains the result of a disjunction (OR-operation) of all bits of bytes 25 to 28 (Out
of specification 1 to 4).
0 In bytes 25 and 28, no signals are active (all bits are set to 0).
1 Collective signal 08:
Indication according to NAMUR recommendation NE 107
The actuator is being worked on; output signals are temporarily invalid.
Contains the result of a disjunction (OR-operation) of all bits of bytes 29 and 30
(Function check 1 and 2).
0 In bytes 29 and 30, no signals are active (all bits are set to 0).
1 Collective signal 10:
Indication according to NAMUR recommendation NE 107
Actuator function failure, output signals are invalid.
Contains the result of a disjunction (OR-operation) of all bits of byte 23 (Failure).
0 In all bits of byte 23, no signals are active (all bits are set to 0).
1 Collective signal 05:
The device is ready for remote control.
No AUMA warnings, AUMA faults or signals according to NAMUR are present.
Bit 7 is set if bits 0 to 6 are deleted.
0 Contains the result of a disjunction (OR-operation) of bits 0 to 6 (device status).
