Valve outputs | Channel-independent functions
Assignments can only be made on the parameter pages "VOx - General -> As-
signments" if service mode is enabled on the "General valve outputs" para-
meter page.
Defining the behaviour at the end of service mode
When service mode is deactivated, the assigned valve outputs are enabled again.
Activation of these outputs using command value telegrams or other functions with a
lower priority is then possible. The parameter "Behaviour at the end" on the para-
meter page "General valve outputs - Service mode" specifies the state to which the
affected valve outputs are set after enabling.
At the end of service mode, the actuator only then executes the configured be-
haviour if, at the time of enabling, no function with a lower priority is active.
Should such a function be active (e.g. forced position), then the actuator will
execute it.
￭
Set the parameter to "No change".
In this setting, assigned valve outputs show no reaction at the end of service
mode. They remain in the most recently set state, until a new command value
presetting is implemented.
￭
Set the parameter to "Close output completely".
In this setting, all the assigned valve outputs close completely. Here too, the
actuators remain in this state until a new command value presetting is imple-
mented.
￭
Set the parameter to "Open output completely".
In this setting, all the assigned valve outputs open completely. The actuators
remain in this state until a new command value presetting is implemented.
￭
Set the parameter to "Track state".
In this configuration, the valve state received during the service function or
preset by the function is tracked at the end of service mode.
Status function of service mode
An active service mode can optionally be displayed by a 1-bit status object. A tele-
gram with the value "1" displays an active service mode. A telegram with the value
"0" displays a deactivated service function.
As soon as service mode is enabled in the ETS, the status communication object is
also available.
Updates of the 2-bit input object from "Service mode active" to "Service mode
active" or from "Service mode inactive" to "Service mode inactive" always
causes retransmission of the status telegram.
The object value of the status function is not transmitted automatically to the
bus after a device reset (ETS programming operation, voltage return).
