Function (continued)
Diagnosis of the electronic compact starter with the user
programme
The input and output signals of the DS2E and RS2E electronic
compact starters can be evaluated in the user programme.
Output DO2 is only controlled in those variants with a brake con-
tact.
The I/O assignment corresponds to the AS-Interface motor
starter profile 7D.

Note:
The brake contact is controlled via the bus separately from the
main circuit. This makes it possible to switch the motor and
brake independently. In the user programme, it must be ensured
that dangerous plant states cannot occur, e.g. unintentional free-
wheeling or blocking of the motor. This also applies to local shut-
down, e.g. in response to an overload tripping operation. Input
signal DI0 can be used to check the status of the device.
Meaning
Manual mode
Device has neen switched to manual mode locally
(switch back to automatic mode using hand-held unit).
Overload/short-circuit tripping
The circuit-breaker recloses once a cooling-off period has elapsed.
FAULT signal
• Defective coil.
• Contact welded.
• Output driver defective (contactor must be tested).
• Simultaneous activation of clockwise and counterclockwise rotation
(user programme must be checked).
