Function (continued)
Diagnosis of the electronic compact starter by means of the
user programme
The input and output signals of the EDS2E and ERS2E electro-
mechanical compact starters can be evaluated in the user pro-
gramme.
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 7E.
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.
Inputs
Outputs
Input signals Device status Meaning
DI0 „Ready“ 0 Device not ready / error Manual mode
Device has been switched to manual mode locally (switch back to auto-
matic mode using hand-held unit).
Tripped signal
Rotary coding switch in position
• Tripping LOCAL: Direct shut-off
• Tripping REMOTE: Remote shut-off or continued operation when pro-
grammed in the user programme
FAULT signal
• No current flowing
- Failure of two phases
- Drawn motor connector
- Supply voltage drop
(< 18 V)
- Current imbalance limit exceeded
- Fault in main circuit of the device
• Hardware fault (Reset after rectification)
