8. Signals (output signals)
8.1. Status signals via output contacts (digital outputs)
Characteristics
Output contacts are used to send status signals (e.g. reaching the end positions,
selector switch position, faults...) as binary signals to the control room.
Status signals only have two states: active or inactive. Active means that the
conditions for the signal are fulfilled.
8.1.1. Assignment of outputs
The output contacts (outputs DOUT 1 – 12) can be assigned to various signals.
Required user level: Specialist (4) or higher.
Device configuration M0053
I/O interface M0139
Digital outputs M0110
Signal DOUT 1 M0109
Table 26: Default values
Default value: Output Default value: Output
Thermal fault Signal DOUT 7 Fault Signal DOUT 1
OPEN Signal DOUT 8 End position CLOSED Signal DOUT 2
Limit switch CLOSED Signal DOUT 9 End position OPEN Signal DOUT 3
Limit switch OPEN Signal DOUT 10 Selector sw. REMOTE Signal DOUT 4
Torque sw. CLOSED Signal DOUT 11 Torque fault CLOSE Signal DOUT 5
Torque sw. OPEN Signal DOUT 12 Torque fault OPEN Signal DOUT 6
8.1.2. Coding the outputs
The output signals
Coding DOUT 1
–
Coding DOUT 12
can be set either to high
active or low active.
●
High active = output contact closed = signal active
●
Low active = output contact open = signal active
Signal active means that the conditions for the signal are fulfilled.
Required user level: Specialist (4) or higher.
Device configuration M0053
I/O interface M0139
Digital outputs M0110
Coding DOUT 1 M0102
Default values:
Coding DOUT 1
=
Low active
Coding DOUT 2
–
Coding DOUT 12
=
High active
8.2. Analogue signals (analogue outputs)
Requirements
If the actuator is equipped with a position transmitter (potentiometer, RWG or EWG),
an analogue position feedback signal is available.
Valve position
Signal: E2 = 0/4 – 20 mA (galvanically isolated)
Designation in the wiring diagram: AOUT1 (position) AOUT2 (position)
