Group Alarm Acknowledgement (SQ)
Allows FB 163 DCM block to acknowledges all active alarms and return to
normal condition for the block when the logic input is a binary “1”.
Block OM operating (BL/OM)
Disables operation from Super ordinate System (OM650) when the input is a
binary “1”. Does not allow manual operations including alarm acknowledge,
operator required actions, manual on, manual off, changeover operation mode
(manual, semiautomatic or automatic) or tag-out.
Block alarm protection command (BL/AP)
• When this input is a binary “1” an executed protection command does not
need to be acknowledged.
A protection command execution with BL/AP causes the following:
• Last status reached by protection is set
• Feed back message shows actual state (on or off)
• Disables the respective counter command
A protection command execution without BL/AP causes the following:
• NOSD (no status discrepancy or message at protection execution) is reset
• Last status reached by protection is set
• Feed back message shows actual state (on or off)
• Disables the respective counter command
• Icon on OM650 flashes red at 2HZ
Acknowledgement of “O” class alarm in mini ASD is required by operator
Auto command on (A/ON)
When this input is a binary “1” and the DCM is in semi or auto operation mode,
and the input EN/ON is a binary 1; the output ALE is activated.
Auto command off (A/OFF)
When this input is a binary “1” and the DCM is in semi or auto operation mode,
and the input EN/ON is a binary 1; the output ALA is activated.
Under voltage limit signal (UGS)
When this input is a binary “1” the maximum under voltage timer TUM is started.
Protection command on (P/ON)
When this input is a binary “1” the DCM is forced on (ALE on) regardless of state
of the enabling inputs
Protection command off (P/OFF)
When this input is a binary “1” the DCM is forced off (ALA off) regardless of the
state of the enabling inputs
