General Description of Functions

7.16 Switch-off Delay
You can use this function to set a switch-off delay for the H2 “Part Present” check signal. This can be used
to mask short-term fluctuations in the vacuum level of the vacuum system. The duration of the switch-off
delay can be set with the parameter [
dlY
] in the configuration menu or via IO-Link. The value can be set
to 10, 50 or 200 ms. To deactivate this function, enter the value [
000
] (= off).
The switch-off delay affects the OUT
2
discrete output, the process data bit in IO-Link and the H2 status dis-
play
If the OUT
2
output is configured as a normally open contact [no], there will be an electrical
switch-off delay. On the other hand, if it is configured as a normally closed contact [nc], there
will be an equivalent switch-on delay.
7.17 ECO Mode
The ejector offers the option to switch off the display to save energy. If ECO mode is activated, the display
is switched off and the system power consumption is reduced after 2 minutes if no buttons are pressed.
ECO mode can be activated and deactivated using the [
Eco
] parameter in the configuration menu or via
IO-Link.
A red dot in the lower right corner of the display indicates that the display has been switched off.
The display is reactivated by pressing any button or by an error message.
If you activate ECO mode using IO-Link, the display will immediately enter energy-saving
mode.
7.18 Write Protection
A PIN can be used to prevent the parameters from being changed via the user menu.
The current settings are still displayed. The PIN is set to
000
on delivery. meaning access to the parame-
ters is not locked. A valid PIN between
001
and
999
must be entered to activate write protection. If
write protection is activated with a customer-specific PIN, the desired parameters can be changed within
one minute after the correct code is entered. If no changes are made within one minute, write protection
is automatically reactivated. The PIN
000
must be set again to permanently deactivate the lock.
Full access to the ejector is still possible via IO-Link even if a PIN is enabled. The current PIN can also be
read out and changed/deleted (PIN =
000
) via IO-Link.
You enter the PIN using the
PIN
parameter in the configuration menu or via IO-Link.
In IO-Link mode, the “Device access locks” default parameter is available to prevent changes to parameter
values using the user menu or IO-Link. You can also prevent the use of the Data storage mechanism de-
scribed in IO-Link Standard V1.1.
Bit Meaning
0 Parameter write access locked
(Parameters cannot be changed via IO-Link)
1 Data storage locked
(Data storage mechanism is not triggered)
2 Local parametrization locked
(Parameters cannot be changed via the user menu)
Coding for the device access locks
A menu lock using the Device access locks parameter has a higher priority than the menu PIN. In other
words, this lock cannot be bypassed by entering a PIN and remains in SIO mode.
It can only be canceled via IO-Link, not via the ejector or the vacuum switch itself.
