7.11Signal Output
7.11.1Setting the Output Function
The ejector has a signal output. The signal output can be configured using the corresponding menu item.
The signal output OUT can be switched between [no] (normally open) and [nc] (normally closed) con-
tact. You can switch it in the configuration menu using the [0-2] menu item or set it via IO-Link. The
function of the limit value H2/h2 (“Part Present” check) is assigned to the signal output OUT.
The signal output is switched on or off when the system vacuum is higher or lower than the relevant
threshold value.
7.11.2Setting the Signal Type
The signal type, or the switching behavior (PNP or NPN) of the electrical signal inputs and the signal out-
put, can be set on the device and therefore does not depend on the version.
You can switch this setting using the [tYP] menu item in the configuration menu or via IO-Link.
The ejector is factory set to PNP.
