Electrical installation
Reset button/restart
When using the V200/V300 with internal restart interlock (see section 3.4.1 “Restart
interlock” on page 14), the operator must press the reset button prior to restart.
Select the correct installation site for the reset button!
Install the reset button outside the hazardous area such that it cannot be operated from
inside the hazardous area. When operating the reset button, the operator must have full
visual command of the hazardous area.
Perform a teach-in procedure after any change to the connection!
The V200/V300 activates the internal restart interlock only after the next teach-in
procedure. Otherwise the system will not switch to green.
The configuration of the internal restart interlock is described in section 8.2 “Internal
restart interlock” on page 46.
External device monitoring (EDM)
You must implement the external device monitoring electrically as follows: When the
contact elements (K1, K2) reach their de-energised position after the protective device has
responded, the two positively guided N/C contacts (k1, k2) must close. 24 V is then
applied at the input of the EDM. If 24 V is not present after the response of the protective
device, then one of the contact elements is faulty and the external device monitoring
prevents the machine starting up again.
Perform a teach-in procedure after any change to the connection!
The V200/V300 activates the external device monitoring only after the next teach-in
procedure. If you place the system in operation after connecting the contacts to the
external device monitoring (EDM)
input without teach-in, then the external device
monitoring will remain deactivated. The system can therefore switch to green despite
faulty contactors.
The configuration of the external device monitoring is described in section 8.3 “External
device monitoring” on page 47.
External key-operated pushbutton for teach-in
To permit remote teach-in and/or to protect the configuration, you can connect an external
key-operated pushbutton for teach-in and lock the internal teach-in key.
•
Once the key-operated pushbutton for teach-in has been operated, the V200/V300
locks the internal teach-in key and saves this configuration in the device. Teach-in can
only be performed using the external key-operated pushbutton for teach-in (see
section 8.4 “Locking the internal teach-in key” on page 48).
•
If you use two V200/V300 in an application, then both systems use the same external
key-operated pushbutton for teach-in (see Fig. 23 on page 35).
