7.6.3 Externally Time-Controlled Blow-Off
In this mode, the blow-off function is set to [
E-t
].
The blow-off pulse is triggered externally by the "Blow-off" signal/command. The "Blow-off" valve is acti-
vated for the specified time [
tbL
]. A longer input signal does not increase the blow-off duration.
The "Blow-off" signal overrides the "Suction" signal, even if the specified blow-off time is very long.
The blow-off time can be set with the parameter [
tbL
] in the main menu. The parameter [
TBL
] is sup-
pressed in the main menu if the operating mode [
-E-
] is active.
7.6.4 Setting the Blow-Off time [P-0: 0x006A]
If the blow-off function of the ejector is set to internally time-controlled [
blo
] = [
1-t
] or externally
time-controlled [
blo
] = [
E-T
] "Blow-off", then the blow-off time [
tbL
] may be specified.
The displayed value indicates the blow-off time in seconds. The time can range from 0.10 to 9.99 seconds.
The parameter [
TBL
] is suppressed in the main menu if the operating mode [
-E-
] is active.
7.7 Selecting a Display Unit [0x004A]
The unit of the displayed vacuum or pressure level can be set using this function.
The function can be configured with the parameter [
uni
] in the configuration menu or via IO-Link.
The following units are available:
Unit Explanation
bar The vacuum level is displayed in mbar.
The pressure level is displayed in bar.
The setting for this unit is [
bAr
].
Pascal The vacuum/pressure values are displayed in kPa.
The setting for this unit is [k
PA
].
Inch of Hg The vacuum/pressure values are displayed in inHg.
The setting for this unit is [
iXG
].
psi The vacuum/pressure values are displayed in psi.
The setting for this unit is [
P5i
].
Selection of the unit only affects the display. The units of the parameters that can be accessed
via IO-Link are not affected by this setting.
7.8 Switch-Off Delay [0x004B]
You can use this function to set a switch-off delay for the H1, H2 and HP1 signals. This can be used to hide
short drops in the pressure or vacuum circuit.
The duration of the switch-off delay can be set for all three signals using the parameter [
dlY
] in the con-
figuration menu, or via IO-Link. Selectable values are 10, 50 and 200 ms. To deactivate this function, enter
the value [
000
] (= off).
The switch-off delay affects the process data bits in IO-Link and the H1 and H2 status indicators.
