100 99 Bus Termination
Indicates if bus termination (120 Ω) is enabled
Bus termination can be set with the configuration tools

Each device has an unambiguous series number, which is either impressed
on or glued to the housing
The series number consists of 4 segments, although only parts 1, 2 and 4
are displayed on Modus

105 104 Malfunction and Service Information
Value is bit-coded. More than one bit can be set to 1
All bits not montioned in the enumeration are not used for this actuator range
Mechanical travel increased: The actuator has been moved outside the
adapted working range
Actuator cannot move: Mechanical overload e.g. blocked actuator, etc.
Internal activity: Actuator performs a test run, adaption, etc.
Gear disengaged: The gear disengaged button is pressed
Bus Watchdog triggered: Timeout for the Bus Watchdog expired
Bit1: Mech travel increased
Bit2: Actuator cannot move
Bit8: Internal activity
Bit9: Gear disengaged
Bit10: Bus Watchdog triggered

108 107 Sensor 1 Type
If Setpoint Source (Register 119) is analog (Hybrid mode) the sensor type 1
can be set to Active(1) in order to see the Setpoint Analog in mV
0: None
1: Active / Hybrid
2: –
3: –
4: Switch
Default: None(0)
– – R / W
109 108 Bus Fail Position
Modbus communication is not monitored as standard. In the event of a
breakdown in communication, the actuator retains the current setpoint
The bus implementation tracks the Modbus communication. If neither
the Setpoint (Register No. 1) nor the Override Control (Register No. 2) is
renewed before the Timeout for Bus Watchdog (Register No. 110) expires,
the actuator controls to the Bus Fail Position
Triggered bus watchdog is indicated in the Malfunction and Service
Information (Register No. 105)
0: None / Last setpoint
1: Fast close
2: Fast open
3: Mid position
(parameterized)
Default: None(0)
– – R / W
110 109 Timeout for Bus Watchdog in s
Time until Bus Fail will be detected. If Bus Watchdog = 0 then deactivated
If Bus Fail Position (Register No. 110) different from 0, the Bus Fail Position
becomes active after the Timeout for Bus Watchdog is expired
0...3‘600
Default: 0
If Bus Fail Position (Register
No. 110) not None(0), then
Default: 120
