Opt/I Safety Stop Pl D Option - Fronius TPS 320i Operating Instructions Manual

OPT/i Safety Stop IMPORTANT! The safety function OPT/i Safety Stop PL d has been designed according
PL d option to EN ISO 13849-1:2008 + AC:2009 as category 3.
This requires two-channel feel of the input signal.
Bridging of two-channel operation (e.g. with a shorting bar) is not permitted and will result
in loss of PL d.
Functional description
The OPT/i Safety Stop PL d option guarantees a safety stop of the power source according
to PL d with controlled end of welding in less than one second.
Every time the power source is switched on, the safety function Safety Stop PL d performs
a self-test.
IMPORTANT! This self-test must be performed at least once a year to check the operation
of the safety shutdown.
If the voltage drops on at least one of 2 inputs, Safety Stop PL d halts the current welding
operation; the wirefeeder motor and the welding voltage are switched off.
The power source outputs an error code. Communication via the robot interface or the bus
system remains unaffected.
To re-start the welding system, the power must be re-connected. An error must be ac-
knowledged via the torch trigger, display or interface and Weld-Start must be carried out
again.
A non-simultaneous shutdown of both inputs (> 750 ms) is output by the system as a crit-
ical, non-resettable error.
The power source is permanently switched off.
A reset is carried out by switching the power source off and on again.
