Schmalz SCPSi - Switch-Off Delay; ECO Mode; Write Protection

7 General Description of Functions
38 / 86 EN-US · 30.30.00.00424 · 07 · 10/23
The selection of the vacuum unit only affects the display. The units of the parameters that can be accessed
via IO-Link are not affected by this setting.
7.14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 output OUT2 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.
7.15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.
7.16Write Protection
7.16.1PIN
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 must be reset to 000 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.
