AUMA ACV 01.2 User Manual

9.2.7. Delay time: set
A failure operation is only performed once the delay time has expired.This prevents
a short-term loss of signal, which does not have an effect on the process, from directly
starting a failure operation
Required user level: Specialist (4) or higher.
Customer settings M0041
Failure behaviour M0378
Delay time M0386
Default value: 00:03.0 min:s (3 seconds)
Setting range: 0.0 ... 30:00.00.0 min:s (30 minutes)
9.3. EMERGENCY behaviour
Application
The EMERGENCY behaviour can be used to determine the actuator behaviour in
an emergency.
Characteristics
●
The function <EMERGENCY behaviour> is initiated by the EMERGENCY signal.
●
The actuator performs a defined EMERGENCY operation. For example, the
actuator moves to a predefined EMERGENCY position (i.e. end position OPEN
or end position CLOSED).
●
As long as the EMERGENCY signal is present, the actuator does not respond
to any other operation commands (EMERGENCY signal has top priority).
●
After initiating the EMERGENCY behaviour, binary operation commands (via
digital inputs) may have to be sent again.
●
Analogue operation commands (e.g. 0/4 – 20 mA) or operation commands via
fieldbus are immediately executed again.
Perform EMERGENCY operation via fieldbus command
For control via fieldbus interface, the EMERGENCY command is done via fieldbus
command Fieldbus EMCY.
Switching behaviour:
●
Fieldbus EMCY = 1 = EMERGENCY behaviour is initiated.
●
Fieldbus EMCY = 0 = No EMERGENCY operation
If the EMERGENCY command is not to be transmitted via a fieldbus command but
using a binary signal, (e.g. + 24 V DC) via <Additional inputs> or via an additional
<Parallel interface>, a digital input has to be available and configured.
Configuration of digital input
Required access level: Specialist (4).
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Example
Use input DIN 4 for signal EMERGENCY:
Parameter: Signal DIN 4 M0118
Setting value: EMERGENCY (wiring diagram designation: EMERGENCY)
Information
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g. Coding DIN 4 M0126), the input is either High active or Low active. For safety
reasons, the EMERGENCY signal input is generally set to Low active.
Perform EMERGENCY operation via digital input
Switching behaviour for coding Low active:
●
Input EMERGENCY = low level (0 V DC or input open-circuit)
EMERGENCY operation is initiated.
