FUNCTIONAL DESCRIPTION:
After interrupting the sensing field of the FF-SYB safety light curtain, both static safety oututs (5, 6) of the receiver switch off.
Then, the normally open contacts of the connected FF-SRE6029 extension module (13/14, 23/24, 33/34, 43/44) will open and
the normally closed contacts (51/52, Y1/Y2) will close. The LED relay output indicators (K1, K2) of the module go off indicating
that the internal safety relays K1 and K2 are de-energized.
After clearing the sensing field of the FF-SYB safety light curtain, press and release the restart push-button to restart the
receiver. If the FF-SRE6029 extension module is operating properly, the normally closed contact (Y1/Y2) for the External Device
Monitoring (EDM) is closed and the static safety outputs of the FF-SYB receiver are energising. The normally open contacts of
the FF-SRE6029 module will close and the normally closed contacts will open. The LED relay output indicators K1 and K2
illuminate. This action will allow the machine to operate.
APPLICATION NOTES
Note (A): Dual channel output safety devices with static safety outputs AND External Device Monitoring (EDM) function (e.g.
FF-SYB safety light curtains).
Note (B): CONFIGURATION CARDS
Various mode settings are possible with the FF-SYB safety light curtain (e. g. start / restart, muting, floating blanking) using
configuration cards. The example above uses the factory setting configuration card for the receiver (#1: manual start, no muting,
no blanking). Refer to the FF-SYB installation manual for more information.
IMPROPER INPUT CONNECTIONS
To ensure the highest level of safety, always connect the two redundant safety device outputs individually to the safety relay
inputs A1(+)/A2(-) and A3(+)/A4(-) of the FF-SRE6029 Extension Module.
IMPROPER EXTENSION MODULE MONITORING
•
The External Device Monitoring (EDM) function checks the correct operation of the internal relays before each FF-SRE6029
activation and is able to detect failures of the internal relays (e.g: welded safety relay contacts).
•
ALWAYS connect the normally closed contact (Y1/Y2) of the extension module to the External Device Monitoring (EDM) loop
of the connected safety device. NEVER use the normally closed contact (51/52) for the EDM monitoring.
Failure to comply with these instructions could result in death or serious injury.
