Operation and indication | Button operation and indication functions
Permanent manual operation mode is active and the LED ǃ is illuminated.
The status LED A1 flashes. The two status LEDs OPEN and CLOSE show the
current status of A1.
After permanent manual operation mode has been switched on, the states of
the outputs last set initially remain active. However, for opened valve outputs,
the pulse width modulation is automatically adjusted to the preset value of
manual operation.
Switching off permanent manual operation mode
The device is in permanent manual operation mode.
￭ Press the ǃ button for at least 5 seconds.

Bus operation is active. LEDs A1...A6 no longer flash, but rather indicate the
output status.
Manual operation is always exited after an ETS programming operation.
Depending on the configuration of the actuator in the ETS, the outputs will be
set to the state last adjusted in manual operation or to the state internally
tracked (e.g. forced position, service operation) when permanent manual oper-
ation mode is switched off.
Operating the outputs
In manual operation mode the outputs can be operated instantly. The outputs are al-
ways activated with pulse width modulation by manual operation with the OPEN com-
mand. The cycle time of the PWM signal for a valve output activated by manual oper-
ation is configured centrally on the parameter page "Manual operation" in the ETS.
The CLOSE command closes the valves completely (0%).
The device is in permanent or temporary manual operation mode.
￭ Press the ǃ button briefly, < 1 s, as many times as necessary until the de-
sired output is selected.
The LED of the selected output A1...A6 flashes. Additionally, the status of the
selected output is indicated by the LED OPEN or CLOSE.
￭ Press the OPEN button.
The valve opens (configured valve direction of action is taken into account).
￭ Press the CLOSE button.
