6.3.7 Manual mode
CAUTION
The output signals may change during set-up in manual mode.
Severe injury to persons and damage to property due to uncontrolled machine
movements
►
The machine must be set up only by persons who are able to assess the
impact of signal changes on the overall machine, facility or system.
In manual mode, the “Suction” and “Blow-off” ejector functions can be controlled independently of the
higher-level controller using the button on the operating panel.
Because the valve protection function is deactivated in manual mode, this function can be used to
locate and rectify leaks in the vacuum circuit.
The valve protection function is not active in manual mode.
Activating manual mode
To activate manual mode, you have to hold down the button on the ejector for at least 3 seconds. In
this operating mode, the “Suction” and “Blow-off” LEDs both flash. The ejector is set to “pneumatically
OFF.”
A prerequisite for activation is that the ejector must also have been in the “pneumatically OFF” state
beforehand. Access is not possible from the suction or blow-off state.
Suction in manual mode
When you press the button again (falling edge), the ejector begins the suction process. The suction
LED is on and the blow-off LED continues to flash.
Blow-off in manual mode
When you press the button again, the blow-off function is activated for as long as you hold down the
button. The blow-off LED is on during this time. The suction LED flashes.
When you release the button, the ejector switches back to the “pneumatically OFF” setting.
When you press the button again, the suction is activated again.
Ending manual mode
To leave manual mode, you have to press down the button for more than 3 seconds when the device
is in the pneumatically OFF state. The “Suction” and “Blow-off” LEDs stop flashing once you leave
manual mode.
A signal change (suction, blow-off) via IO-Link also ends manual mode.
CAUTION
External signals may end manual mode automatically.
This can cause the object being handled to move due to suction or blow-
off force.
Serious personal injury and/or damage to property
Unforeseen work steps
► There must be no people in the system danger area while it is in operation.
