Disabling control deactivation
(applies to ECD-IV and ECD-LV-...-RD)
The automatic control deactivation can be disabled by the condition monitoring
functions or disabled and enabled via the input screen of IO-Link (line
[dCS]
).
[dCS = oFF]:
The ejector switches to the “Permanent suction” operating state if the
leak rate is too high and the valve switches too frequently.
[dCS = on]:
Permanent suction is deactivated; the ejector continues regulating
despite the high leak rate or a control frequency of >6/3 s.
Blow-off modes
The input screen of IO-Link (line
[bLo]
) in the configuration menu can be used to
adjust three different blow-off modes:
Externally controlled blowing off
W
The “Blow-off” valve is directly actuated via the “Blow-off” signal input. The
ejector will blow-off as long as the signal is present.
W
Setting for this operating mode:
[-E-]
Internally time-controlled blowing off
W
The “Blow off” valve is automatically actuated for the set time
[tbL]
when exiting
the “Suction” operating state. This function saves an output on the controller.
W
Setting for this operating mode:
[I-t]
Externally time-controlled blowing off
The blow-off pulse is actuated externally by the “Blow-off” input. The “Blow-off” valve
is actuated for the set time
[tbL]
. Increasing the input signal does not increase the
blow-off period.
Setting of the blow-off function for this operating mode is
[-E-t]
.
Signal output
The ejector features a signal output, which can be configured using the
corresponding menu item.
Output function
The signal output can be switched between the normally open contact
[no]
(normally open) or the normally closed contact
[nc]
(normally closed).
The switching is adjusted via the input screen of IO-Link (line
[o-2]
).
The function for the switching threshold H2-h2 (parts control) is assigned to the
signal output OUT 2.
Output type
The output type can be used to switch between PNP and NPN.
Furthermore, this function is also used to configure the signal inputs at the same
time.
The switching is adjusted via the input screen of IO-Link (line
[tYP]
).
WARNING
Personal injury or property damage caused by moving objects
Disabling control deactivation
[dCS = on]
(ECD-IV)/
[dCS = YES]
(ECD-LV) can lead to
the suction valve being controlled at a very high rate. This results in a risk of the
ejector being destroyed!
O
Make sure that no persons are in the transporting area when using control
deactivation.
O
Do not disable control deactivation when switching frequently.
The setting
[dCS = on]
(ECD-IV)/
[dCS = YES]
(ECD-LV) is only available if the
control function
[ctr = on]
or
[ctr = onS]
(only ECD-IV)
is selected.
In the event of undervoltage or a loss of voltage, the ejector variant NO
responds despite permanent suction being deactivated via
[dCS = on]
(ECD-IV)/
[dCS = YES]
(ECD-LV) with permanent suction.
The “Blow-off” operating state can still be triggered by the “Blow-off” signal
input, even in
[I-t]
mode.
The length of the blow-off time
[tbL]
is adjusted in the home menu.
This menu item is suppressed in the operating mode
[-E-]
.
The number in the display indicates the blow-off time in seconds. Blow-off
times between 0.10 s to 9.99 s can be selected.
Selecting the vacuum unit
The menu item
[uni]
in the configuration menu can be used to select the unit for the
vacuum value displayed from the following three units
Bar
Vacuum values are displayed in the unit mbar:
[-bA]
Pascal
Vacuum values are displayed in the unit kPA:
[-PA]
inchHg
Vacuum values are displayed in the unit inHG:
[-iH]
The function can be adjusted via the input screen of IO-Link (line
[uni]
).
Switch-off delay for the parts control signal H2
This function can be used to select a switch-off delay for the parts control signal H2.
This can be used to suppress short-term drops in the vacuum circuit.
O
Use the input screen of IO-Link (line
[dlY]
) to adjust the length of the switch-off
delay.
You can select values of 10, 50 or 200 ms.
O
To deactivate the switch-off delay, select the value 0 (= off).
ECO mode
Activating ECO mode switches off the display two minutes after the last button
activation and reduces the system's current consumption.
A red dot in the bottom right-hand corner of the display indicates that the display is
switched off. Press any button to reactivate the display again. The display reactivates
again when an error message appears.
O
Use the input screen of IO-Link (line
[ECO]
) to activate/deactivate ECO mode.
Write protection
A PIN code can be used to prevent the parameters from being changed in the user
menu. The display of the current settings is still guaranteed.
Upon delivery of the device, the PIN code is 000. This means that access to the
parameters is not locked. To activate write protection, you must enter a valid PIN
code between 001 and 999.
If write protection is activated by a customer-specific PIN code, the required
parameters can be adjusted within one minute of the correct code being entered.
If no changes are made within one minute, write protection is automatically activated
again. To permanently enable the display, you must set the PIN code to 000 again.
Via IO-Link fully access to the ejector is possible even if the PIN code is active.
In addition, the IO-Link can be used to read and change or delete (PIN code = 000) the
current PIN code.
O
Use the input screen of IO-Link (line
[PIN]
) to enter the PIN code.
The selection of the vacuum unit only affects the display of the ejector.
The units of the parameters accessible via the IO-Link are not affected by
this setting.
The switch-off delay affects the discrete output OUT2, the process data bit
in IO-Link and the status display H2
When the output OUT2 is configured as normally open
[no]
, an electrical
switch-off delay is applied. When configured as normally closed
[nc]
,
a switch-on delay is applied.
Activation of the ECO mode immediately sets the display to the energy
saving mode.
As the state of signal inputs and outputs can change as a result of
configuration during active operation, we recommend using a PIN code.
