AUMA SAM Ex 07.1 - 3 Additional Information to the Legend for Wiring Diagrams

3. Additional information to the legend for wiring diagrams
Information A: A running indication is possible with blinker transmitter (S5) installed
(opening and closing of contacts)

The contacts remain closed in the end positions.
When connected to an external PLC the blinking signal can be switched off
via the DIP-switches (table 3, page 20).
Information B: The type of seating in the end positions is determined by the valve
manufacturer. Setting is possible at the programming switches S1-2 and
S3-2 (see subclause 15.2, page 20). The tripping of a torque switch in an
intermediate position switches off the actuator and gives a fault signal.
The limit switches serve for signalisation when switching off by torque
seating. 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 given.
For further programming possibilities, e.g. self-retaining in operation mode
REMOTE, see table 3, page 20.
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 in the programming, refer to table 3,
page 20.
Information E: Input signals according to DIN 19 240.
The nominal current of the inputs X
K
2; X
K
3 and X
K
4 is 10-15 mA. If 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 rotating field is automatically
corrected. In case of a phase failure the actuator stops. This fault is
indicated at LED V14 on the interface board. 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.
