OPEN / CLOSE (Code AE)
Description
The event occurs if a valve po-
sition is read which can never
be achieved in the "Open" dir-
ection.
The events occur if the dis-
tance between the OPEN and
CLOSED positions determined
during initialization is implaus-
ible.
The event occurs if the actu-
ator does not have a valid cal-
ibration. The actuator is calib-
rated in the factory.
The event occurs when a short
circuit is present at pin 5 (di-
gital input/digital output).
The event occurs when a short
circuit is present at pin 6 (di-
gital output (IO-Link)).
The event occurs when it has
been determined when starting
the actuator that the specific
data in the actuator's read-only
memory has been changed un-
intentionally.
The event occurs when it is
has been determined when
starting the actuator that the
configuration data in the actu-
ator's read-only memory has
been changed unintentionally.
The configuration data that
has been changed has been re-
set to its default values. The
event serves to signal the
changes in the configuration
data.
Possible cause
Fault in valve position detec-
tion.
Error when replacing a dia-
phragm (stroke of the valve in
incorrect area).
Actuator has been fitted on the
valve incorrectly (stroke of the
valve in the incorrect area).
Valve is blocked (for example,
solid stuck in valve).
Valve is corroded (rusted in
place).
Valve not yet initialized.
Initialization carried out with
incorrectly mounted valve
(spindle, diaphragm or valve
body incorrectly mounted, for
example).
Supply line insulation is dam-
aged.
Incorrect pin configuration.
Incorrect wiring of the pin.
Supply line insulation is dam-
aged.
Incorrect wiring of the pin.
Save values in the read-only
memory in case of power fail-
ure (eSyStep OPEN/CLOSE
does not have any power buf-
fering).
Save values in the read-only
memory in case of power fail-
ure (eSyStep OPEN/CLOSE
does not have any power buf-
fering).

Troubleshooting
Check valve/diaphragm
Check valve
Carry out initialization if valve
is OK
Contact GEMÜ Support
Check supply line
Check pin configuration
Check the wiring of the pin
Check supply line
Check the wiring of the pin
It is uncritical data in the case
of this event, the actuator still
functions
Check the configuration of the
actuator
