4. ELECTRICAL CONNECTIONS
To connect the
photocells and safety
devices, refer
to paragraph 4.1.1
Released beam
Integrated
flashing
traffic light
4.1 Terminal board J1 (inputs)
OPEN - Open” command (N.O. - terminal 3):means anypulse
generator (e.g. button) which, by closing a contact, commands
openingand/orclosingofthebarrier.
CLOSE - Close” command (N.O. - terminal 4):meansanypulse
generator(e.g.button)which,byclosingacontact,commandsclosing
of the barrier.
FSW - Safety contact when closing (N.C. - terminal 5):
thepurpose
oftheclosingsafetiesistoprotecttheareaaffectedbythemovement
ofthebarrierduringtheclosingphase,reversingitsmotion.They
never trip during the opening cycle.
TheclosingSafeties,ifengagedwhentheautomatedsystemisopen,
preventtheclosingmovement.
If CLOSE safety devices are not connected, jumper
terminals FSW and GND (Fig. 26) and leave the FAILSAFE
function (parameter
o1 in Advanced Conguration)
set on the default value (disabled)
STP - STOP contact (N.C. - terminal 6):
meansanydevice(e.g.
button) which, by opening a contact, can stop movement of the
automatedsystem.
If STOP safety devices are not connected, jumper
terminals STOP and GND (Fig. 26)
ALM - Emergency contact (N.C. - terminal 7):
meansanydevice
(e.g.switch)which,ifactivatedinasituationofemergency,willopen
thebarrieruntilthecontactisrestored.Whenactivated,thisinputhas
priorityoveranyothercommand.
If emergency safety devices are not connected, jumper
terminals ALM and GND (Fig. 26)
GND (terminals 8-9) - Accessoriespowersupplyminus
+24 (terminals 10-11) - Accessoriespowersupplyplus
The maximum load of the accessories is 800mA. To
calculate absorption, refer to the instructions included
with the individual accessories.
4.1.1 Connecting the safety devices
TheE680controlboardfeaturesaninputforclosing safety devices,
whichtripduringclosingoftheautomatedsystem,providedtoprotect
thegateareafromtheriskofimpact.
Thesedevicesmustuseasignalwith“N.C.”contact,andmustbe
connectedinseriestotherelayphotocellsthatmaybeinstalledon
thesystem,asshowninFig.23toFig.26.
