Suction ON
When the air saving function is activated and there is a high leakage level in the gripping system, the
ejector switches between the Suction and Suction Off states very frequently. The number of valve switch-
ing procedures thus increases rapidly within a short time.
To protect the ejector and increase its service life, the ejector automatically deactivates the air saving
function and switches to continuous suction if the switching frequency > 6/3 s (more than 6 switching op-
erations within 3 seconds). In this case the ejector remains in the Suction state.
It also issues and warning and sets the corresponding condition monitoring bit.
