Information A:
A running indication is possible if blinker transmitter (S5) is installed
(opening and closing of contacts).

Contacts remain closed in end position.
When connected to an external PLC, the blinking signal can be switched off
via the DIP-switches (table 4, page 33).
Information B:
The type of seating in the end positions is determined by the valve manufac-
turer. The setting is done at the programming switches S1-2 and S3-2
(see page 33). The tripping of a torque switch in an intermediate position
switches off the actuator and causes a fault signal.
The limit switches serve for signalisation when switching off by torque seat-
ing. They need to be set so that the appropriate switch is tripped shortly
before reaching the end position. If the torque switch trips before the limit
switch, the actuator is switched off and a fault signal is generated.
For further programming possibilities, e.g. self-retaining in operation mode
REMOTE, see table 4, page 33.
Information D:
The following faults are registered and can be transmitted to the control
room as a potential-free collective fault signal:
- Power failure
- Phase failure
- Motor protection tripped
- Torque switch tripped in mid-travel.
This signal can be switched off on the logic board, see table 4, page 33.
Information E:
Input signals according to DIN 19 240.
The nominal operation current of inputs X
K
2, X
K
3, and X
K
4 amounts to
10 – 15 mA. If the internal voltage 24 V DC is used for remote control, it
must only be connected via potential-free contacts.
Information F:
In case of wrong phase sequence, the running direction is automatically
adjusted. In case of a phase failure, the actuator stops. The fault is indicated
at LED V14 on the interface board (see page 32). For collective fault signal,
see information D.
Information G:
Potential-free contacts are available for signals. The internal control voltage
(X
K
11/+ 24 V and X
K
5/– 24V) must not be used for external lamps, relays,
etc.
