Flexible Safety Unit
Description of operation
The input terminals for power supply.
Connect the power source to the A1 and A2
terminals.
To set the safety outputs in the ON state, the HIGH
state signals must be input to both safety input 1 and
safety input 2. Otherwise the safety outputs cannot
be in the ON state.
To set the safety outputs in the ON state, the ON
state signal must be input to T33.
Otherwise the safety outputs cannot be in the ON
state.
To set the safety outputs in the ON state, the signal
input to T32 must change from the OFF state to the
ON state, and then to the OFF state. Otherwise the
safety outputs cannot be in the ON state.
A logical AND connection means that one unit (Unit
A) outputs a safety signal "a" to a subsequent unit
(Unit B) and Unit B calculates the logical
multiplication (AND) (i.e., outputs the AND) of the
signal "a" and safety signal "b", which is input to Unit
B.
Thereby the logic of the safety output of Unit B is "a"
AND "b". (An AND of inputs "a" and "b" is output.)
To set the safety outputs of the subsequent Unit in
the ON state, its logical AND connection preset
switch must be set to AND (enable) and the HIGH
state signal must be input to T41 of the subsequent
unit.
Selects the mode for the failure detecting (cross fault
detecting) function for the safety inputs of G9SX
corresponding to the connection of the cross fault
detection input.
Turns ON/OFF according to the state of the safety
inputs, feedback/reset inputs, and logical AND
connection inputs.
During OFF-delay state, the Instantaneous safety
outputs are not able to turn ON.
OFF-delayed safety outputs.
The OFF-delay time is set by the OFF-delay preset
switch.
When the delay time is set to zero, these outputs can
be used as non-delay outputs.
Outputs a signal of the same logic as the
instantaneous safety outputs.
Outputs a signal of the same logic as the
instantaneous safety outputs
Outputs when the error indicator is lit or blinking.
