AUMA AC 01.2 - Priority REMOTE

Enable LOCAL M0628
Default value: Sel. sw. Local
Setting values:
Sel. sw. Local
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.
Sel. sw. Local + Off
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.
Information
If the <Priority REMOTE> function is also activated, the two functions should have
different setting values. In case of identical setting values, e.g. Sel. sw. Local + Off,
the <Enable local controls> function will have no function, since the actuator controls
will be exclusively in operation mode REMOTE if the enable signal is missing.
9.5. Priority REMOTE
Properties
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.
Application
No changing possibility via selector switch from LOCAL
Priority REMOTE over fieldbus command
For control via fieldbus interface, the Priority REMOTE command is done via fieldbus
command Fieldb. enable LOCAL.
Switching behaviour:
●
Fieldb. enable LOCAL = 1 = enable:
Operation via local controls enabled
●
Fieldb. enable LOCAL = 0 = Priority REMOTE:
Operation via local controls disabled
If the operation commands are not transmitted via fieldbus commands, but via
<Additional inputs> or additional <Parallel interface>, a digital input has to be available
and configured for the <Priority REMOTE> function.
Configuration of digital input
Required user level: Specialist (4).
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Example
Use input DIN 5 for signal Enable Local:
Parameters: Signal DIN 5 M0122
Setting value: Enable Local (wiring diagram designation: Enable LOCAL)
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.
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
