Information
Setting values:
Function <Local controls: enable from REMOTE> deactivated.
Function <Local controls: enable from REMOTE> activated.
The enable behaviour determines which selector switch functions (LOCAL, OFF)
require an additional enable signal.
Required user level: Specialist (4) or higher.
Customer settings M0041
Local controls M0075
Enable LOCAL M0628
Default value: Sel. sw. Local
Setting values:
Disabling or enabling is only effective in operation mode LOCAL (selector switch is
in position Local control). If no enable signal is present, operation via push buttons
on the local controls is disabled and the display shows the following signal: Disabled.
Disabling or enabling is effective in operation modes LOCAL and OFF (selector
switch positions Local control and 0). If no enable signal is present, operation via
push buttons on the local controls is disabled and the display shows the following
signal: Disabled.
Option
A control signal can provide REMOTE control with priority over actuator operation
via local controls (irrespective of the selector switch position)
This function uses the same input signal as the <Enabling local controls> function.
No changing possibility via selector switch from LOCAL
For the <Priority REMOTE> function, a digital input for the signal Enable Local has
to be available and configured.
Configuration of digital input
Required user level: Specialist (4).
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Use input DIN 5 for signal Enable Local:
Parameter: Signal DIN 5 M0122
Setting value: Enable Local (wiring diagram designation:
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.
Priority REMOTE via digital input
Switching behaviour for coding High active:
Input Enable Local = high level (standard: +24 V DC):
Operation via local controls enabled
Input Enable Local = low level (0 V DC or input open):
Priority REMOTE: Operation via local controls disabled
