Information
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g. Coding DIN 5 M0127), the input is either High active or Low active. Default
setting is High active.
Enable/disable commands via digital input
Switching- behaviour for coding High active:
●
Input Enable OPEN = low level (0 V DC or input open):
Operation command enabled.
●
Input or Enable OPEN = high level (default: +24 V DC):
Operation command disabled,
9.6.1. Interlock: activate
Required user level: Specialist (4) or higher.
Device configuration M0053
Application functions M0178
Activation M0212
Interlock M0663
Default value: Function not active
Setting values:
Function not active
Function <Interlock (enable operation commands)> deactivated.
Function active
Function <Interlock (enable operation commands)> activated.
9.6.2. Source of Interlock enable signal: set
Customer settings M0041
Interlock M0664
Interlock source M1013
Default value: Active comm. source
Setting values:
Active comm. source
Signals for enabling operation commands are sent via the active interface. I.e.
changing the command source also changes the failure source of the enable signal.
Interface
The enable signal for the operation commands must be configured as binary signal
(default: +24 V DC) at a digital input (parameter: Enable OPEN/Enable CLOSE).
Fieldbus
The enable signal for the operation commands must be triggered by the fieldbus
commands Interlock OPEN or Interlock CLOSE.
9.6.3. Operation mode for interlock
The additional enable signal can be activated for different operation modes.
Customer settings M0041
Interlock M0664
Oper. mode Interlock M0665
Default value: Off both directions
Setting values:
Off
Interlock is off.
Remote
Interlock is active in operation modes: RemoteRemote II Fieldbus
Local
Interlock is active in operation modes: Local, Service
Remote and local
Interlock is active in operation modes: Remote, Remote II, Fieldbus, Local, Service
9.6.4. Interlock behaviour (running direction)
The Interlock behaviour determines which selector switch functions (LOCAL, OFF)
require an additional enable signal.
