Digital Alarm Manager Description

 

Orion's digital alarm manager is a "Plug and Play" device that connects anywhere on the 2-wire RS485 link and requires no communications configuration.  The alarm manager provides "First-In" digital alarm capability for hi-speed digital systems that require that the "state change" order of the digital contacts be monitored.  Typical application would be to monitor a combustion safety operational interlock system providing system status and history of interlock action.

 

The Digital Alarm Manager system can monitor up to 26 contact closure inputs by using "Plug-In" cards that require no configuration.  Contact closure order is monitored within 15ms.  The digital alarm manager can also be used as an input status manager only (no alarms during Orion runtime) with configurable tag names and "order or use" for each input.

 

The Orion system will monitor up to 30 digital alarms continuously before it is necessary to reset the digital alarm manager from the Orion interface.  After 30 alarms are listed in the real time alarm grid, the following message will appear at the top of the alarm grid:  "DigiMgr Full! Reset To Clear." 

Additional digital alarms will not be posted until the "Reset Digital" button is pressed.

 

 

All real time alarms are written to the alarm history log and are stored internally for more than one year so complete alarm history is available at any time. See Alarm Views & History for more information.

Common Alarm Outputs for Audible/Light or other Annuciation

 

The basic system has twelve 24VDC digital inputs/8 outputs and is powered by the same 24VDC power supply used to supply the Orion interface. For detail information on the physical aspects of the CPU download Orion Manual.

 

Output Q0 (transistor) and output Q2 (relay) on the main CPU are used for an audible alarm.   This alarm is silenced from the Orion interface. Each time a new alarm is monitored, the audible alarm contacts will close.  If the digital alarm monitor (current order of contact state change) is reset from the Orion interface and an alarm condition still exists, the audible alarm contacts will close again. This protects the user from clearing the digital alarm module while an alarm condition still exists.  Any time the alarm grid at the Orion interface is cleared, the grid will re-report any alarms that still exist in the digital alarm manager.

Master On and Sync Inputs

 

The first input on the main CPU (I0) is a "Master On" input that allows the alarm manager to "sync" to the digital process it is monitoring.  If the first input is not energized (or shorted if process sync not required), the alarm manager will not be operational.

 

The second input on the main CPU (I1) is used as a "Master On" synchronization input check.   In some cases, the "Master On" input (I0) that enables all alarm inputs will not be energized at the start of the process, but delayed until sometime after the process starts (i.e. call for heat in combustion system is delayed until purge is satisfied).  Under these conditions the process needs a check to make sure that the master input is energized and the digital alarm system is active.  I1 on the main CPU is a N.O. contact that when energized starts a delay timer (delay programmable from Orion runtime setup section).  When the delay timer has elapsed, if I0 ("Master On") input is not energized, the alarm indication "Digi AlmMgr Master Sync Error" will be posted in the real time alarm display.  The alarm outputs Q0 and Q2 will also be set and can be wired to an audible alarm, buzzer or light.  Outputs Q0 and Q2 will be reset when the "Ack/Silence" button is pressed from the Orion alarm manager display.

 

Notes for using "Master On" synchronization input (I1): 

 

1.       If a "Master On" synchronization check is not required, do not wire to I1 on the main CPU since the input is N.0.

 

2.       If the "Master On" synchronization input (I1) is used, it must remain energized for the complete process time that the Master On (I0) input is energized (after I1 delay period).  This is done as a safety to ensure that the "Master On" input (I0) does not de-energized at sometime during the process and disable the alarm manager without a warning to the user.

 

3.       If a "Master On" synchronization input alarm occurs, external system wiring/logic should be designed so the "Master On" input (I0) and "Master On" synchronization input (I1) are de-energized before the next system start.  If the "Master On" synchronization input (I1) is not de-energized, the delay timer will not be reset for the next system start.  As long as the "Master On" input (I0) is energized, the alarm manager will be active and all digital alarms monitored.

 

 

Inputs I2 through I13 on the main CPU are 24VDC inputs and are setup for N.0.operation. Time delays for all inputs are adjustable from the Orion interface to meet different operational requirements.   When "process syncing" is not required, short input 0 so the alarm manager is operation at power up.

Using the Alarm Manager for Input Status only

When alarm monitoring during the Orion runtime is not required, the digital alarm manager can be used for status monitoring of digital inputs only.  This is configurable at the Orion configurator.  When using the alarm manager as an input status monitor only, tag names for all inputs can be edited by the user as well as selected for use on the "Input Status" monitor screen (during Orion runtime).  The tag names for the "Master On" input (I0) and "Master Sync" input (I1) are configurable as well so the operator can use all 12 inputs on the main CPU for status monitoring only.  See configuration section for setup information regarding the digital alarm manager.

Tagnames for Digital Alarms & Master On / Synch

The Digital Alarm Tagname screen provides the user with the ability to enter a custom tagname for each contact closure input supported by the digital alarm manager.  The tagname information is displayed in the Orion runtime alarm grid if a contact closure alarm occurs. Press the "TagName"  field to  display a pop-up text entry dialog.  Use the right/left arrows to navigate through all 26  contact closure tagnames.  Press the "Select checkbox if input is being used" checkbox so the Orion runtime will dynamically display only the digital inputs selected for use by the user in the "Input Monitor" and "Digital Alarm Delay" screens.

 

 

The "Master On/Master Sync" tagname screen allows the user to customize the name for both inputs whether the system is used as a digital alarm manager or input status monitor only.

Hardware Required for Digital Alarm Manager

FC4A-HPC3:           RS485 interface for digital alarm manager (required).

FC4A-D20RS1:     Main CPU with twelve 24VDC digital inputs and 8 outputs (required).

FC4A-N08A11:     Eight channel, 110VAC digital input module (optional).

 

Note: The 8-channel "AC" input modules (FC4A-N08A11) are optional, and required only when:

 

1.  110VAC contact closure inputs are required for the application.

2.  More than 10 contact closure inputs equipped on the main CPU are required.

 

A total of two 8-channel, 110VAC input cards can be connected to the digital alarm manager for a total of sixteen, 110VAC inputs.  These cards are "plug and play" and require no configuration or programming at the hardware level. 

 

Configuration Notes:

 

1.             The Orion configurator allows the user to select only the inputs required at the configuration level.   Any inputs not used at the hardware level will not show up in the digital input status monitor or digital alarm delay settings if not selected at the Orion configurator.

 

Example:  User requires five, 24VDC inputs and four 110VAC inputs for digital alarm management.  At the Orion configurator level, the user can select any of the ten 24VDC digital inputs on the main CPU or any of the eight 110VAC inputs for use.  For each digital input the user can assign a tagname as well as select the option:  "Select checkbox if input is being used: ".  If the checkbox is not selected, the input will not show up on the Orion runtime input monitor status screen or the alarm delay settings screen.

 

Inputs not selected for use in the configurator will still be posted to the alarm grid if the input is energized at the hardware level.  This can be used as a trouble-shooting tool to check for wiring issues at the hardware level.
