Off
By-pass mode is deactivated. Local Stop function is even active during EMERGENCY
operation.
On
By-pass mode is activated. Local Stop function is deactivated during EMERGENCY
operation.
9.3.14. Delay time for EMERGENCY operation
An EMERGENCY operation is only performed once the delay time has expired.
Consequently, a short-term signal failure will not have an impact on the process and
will not immediately initiate an EMERGENCY operation.
Required user level: Specialist (4) or higher.

Application
●

Characteristics
The selector switch functions LOCAL and/or OFF may be enabled or disabled.
Condition
For the function <Enable local controls>, 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
Example
Use input DIN 5 for signal Enable Local:
Parameter: 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.
Enable/disable local controls 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):
Operation via local controls disabled
