Omron S8M - 2-6 Shutdown Sequence Function

31
Shutdown Sequence Function Section 2-6
• The branch output's status indicator will flash green during the startup
sequence time until it is connected.
• The startup sequence's operation can be verified in Test Mode. For
details, refer to 5-3 Checking Sequence Operation.
• The startup sequence's operation can also be verified from the Support
Tool by clicking the Startup Sequence Button. (For details, refer to
page 94.)
Note The startup sequence functions in the following processes:
• Connecting when power is turned ON
• Reconnecting during a reset operation
• Startup sequence executed by CompoWay/F command (Startup
Sequence)
• Simultaneous connection of all outputs in Test Mode
• Startup sequence executed from the Support Tool
2-6 Shutdown Sequence Function
When the S8M's input power supply is turned OFF, all of the branch outputs
are turned OFF (disconnected) simultaneously. On the other hand, when the
branch outputs are cut off by the external tripping input or communications, a
time delay (see note 1) can be applied between the branch output disconnec-
tions.
Note (1) The time delay can be set between 0.0 and 99.9 s. (If the delay is set to
0.0 s, the startup sequence will not operate and the branch output will be
cut off immediately.)
(2) The shutdown sequence is designed for the four branch outputs on one
S8M. It does not provide time synchronization between outputs on more
than one S8M.
