Safety Outputs
The safety output blocks are the fourth stage of the configuration. Many of the
blocks have common features.
Input Connection
Each output block has one input connection. This input connection can be
connected to only Logic Level B blocks.
Feedback
The Immediate OFF, ON Delay, and OFF Delay blocks have a feedback
parameter. To use the feedback parameter, a feedback input block must be
declared. If a feedback input block is not available, the feedback parameter is set
to “None”, and can be considered to be always HI.
Reset
The reset parameter must be set to either automatic or manual.
•
If set to automatic, the output turns on when the input received from the
Logic Level B block is HI.
•
If the reset is set to manual, a reset input block must be declared. Before the
reset button is pressed, the input that is received from the Logic Level B
block must be HI. Then, the output turns on if the reset button must be
pressed and held for at least 0.25 s and released within 3 s.
Timing
Timing is used in the ON Delay, OFF Delay, and Jog functions.
The timing can be set between 50…300,000 ms (5 minutes) in 50 ms increments.
Output Connections
The output of the block can be connected to one or more of the following wiring
terminals:
•
12…17 Multi-Purpose (MP)
•
18…21 Embedded Output (EO)
•
00…03 plug-in 1 module (not safety rated)
•
00…03 plug-in 2 module (not safety rated)
The multi-purpose outputs can be configured to operate with pulse test (PT) or
without test pulses (No PT). The embedded terminals always operate with test
pulses. Terminals 20 and 21 can be configured as Single Wire Safety (SWS)
output.
WARNING: The plug-in outputs must only be used for nonsafety rated
purposes.
