Bypass / Unbypass a Device

How to Bypass a Device

  BYPASS       

Bypass allows an operator to prevent alarms from a certain device being displayed on the ECS.  This is useful when a malfunctioning device is sending identical, repetitive messages to the SCOREBOARD.  When a device is bypassed, identical alarms from the device are erased, except for the oldest instance of that alarm.  Once a device is in Bypass, additional events received from that device will be discarded.

This is a TOGGLE type of a function.  If the alarm is not currently in Bypass, the icon will perform a BYPASS operation.  If the alarm is currently in Bypass (By), the icon will perform an UNBYPASS operation.

BYPASS Procedure

• Select any acknowledged alarm generated by the device.
• Click the BYPASS icon
• Enter Comments into the Alarm Comment Form explaining why the bypass action is being taken.

• Click OK.  The selected alarm's Device State changes to By.  All occurrences of the alarm, except for the original identical alarm, disappear.  No further messages from this device will appear until the device is UNBYPASS ed.

• Continue action(s) necessary to resolve the alarm.

How to Restore a Bypassed Device

  UNBYPASS

After a bypassed device is repaired, or is otherwise ready to be brought back onlin, the Unbypass command is issued.  The device then sends messages to the system normally.

UNBYPASS Procedure

• Using the mouse, select a bypassed alarm from the SCOREBOARD.
• Click the BYPASS button.  The UNBYPASS dialog will appear.
• Enter Remarks explaining the reason the unbypass action is being taken.  Click OK.
• Click UNBPASS.  [Bypass is a toggle button, it changes from Bypass to Unbypass then back to Bypass each time it is pressed]

• Enter Comments into the Alarm Comment Form explaining why the unbypass action is being taken.
• Click OK.  The selected alarm's Device State changes to either the current state of the device or to Un (unknown).  Any events now received from this device will again be displayed on the SCOREBOARD.
