ELECTRICAL INSTALLATION

ELECTRICAL SHOCK

Remove power from FF-SR Series control modules and
machine during installation.
Failure to comply with these instructions could
result in death or serious injury.
Multiple wiring configurations are possible for the
FF-SRE6029 extension control module and only general
guidelines are provided in this installation manual.
Refer to the important application warnings (page 5)
and the application examples (pages 6 through 7) for
more details.

FUNCTIONAL DESCRIPTION

In the case of an emergency stop condition, the safety
device connected to the FF-SRE6029 module is actuated
and the internal safety relays K1 and K2 de-energise. The
normally open safety contacts (13/14...43/44) will open
and the normally closed safety contacts (51/52) will close.
The emergency stop condition is signalled to the machine
control circuitry by the module's safety contacts to stop the
hazard and remove power.
As soon as the safety device is released, power is applied
to A1(+)/A2(-), A3(+)/A4(-) and the relays K1 and K2
energise. The normally open contacts will close and the
normally closed contact will open.
Both relays K1 and K2 must be energized to have the
normally open contacts in a closed condition. If one of the
safety relays de-energizes, the normally open contacts will
open.
One or more FF-SRE6029 Extension Modules can be
cascaded or external contactors with positive guided
safety contacts can be used to increase the number of
contacts.
If multiple safety contacts are used in parallel with one
load, the maximum admissible current can be increased.

LED INDICATORS

The FF-SRE6029 module has two green LED status
indicators (K1 and K2) as illustrated in Figure 8.
Illuminated K1 and/or K2 LEDs indicate(s) that the
corresponding internal safety relay is energized.
