STATUS MONITOR FRONT PANEL

      

The left hand side of the Status Monitor Front Panel contains the Data Display Section which consists of the 7-Segment LED Display, individual LEDs to indicate type of information is shown in the 7-Segment Display, and two push buttons, SELECT and DISPLAY.

The center of the Status Monitor Front Panel contains the Control Section which consists of two control push buttons, LOCAL/REMOTE and TEST-STBY, as well as the corresponding LED indicators, "Local" and "Test."

     

The Status Display Section contains the three status LED indicators including "Major Alarm", "Minor Alarm", and (status monitor) "Power On."

The right hand side of the Status Monitor Front Panel contains the Communications Section which consists of two RJ-45 connectors, for the HMS interface daisy-chain CAT-5 cables, and the "Comm Okay" LED indicator

DATA  DISPLAY  SECTION

 

The data display is controlled by SELECT and DISPLAY push buttons.  The SELECT button toggles the display between minimum and maximum stored data values.  The "MIN" LED is illuminated when the lowest or minimum stored value is displayed.  The "MAX" LED is illuminated when the highest or maximum stored value is displayed.

    

The DISPLAY  button changes the displayed parameter with each press of the button.  The six displayed parameters are further identified by a corresponding LED.  In the photograph of the Data Display Section, the "Line Voltage" LED is illuminated and the value shown in the 7-segment display is, therefore, 119 volts AC.

 

To use the Data Display, press the DISPLAY push button and observe the individual LEDs cycle through the group, and the value displayed in the 7-Segment Display change accordingly.  Stop cycling at the preferred value for display.

 

For some displayed values, there are maximum and minimum extremes available for display.  The ‘Standby Cycles’ and ‘Hours-Standby’ do not have a Max/Min value.  To use the Max/Min function, navigate to one of the four values for which a Max/Min exists then press the SELECT push button and observe the Max/Min LEDs.  Each press of SELECT cycles through the Max/Min values and the corresponding Max/Min LED is illuminated.  Also, the value displayed in the 7-Segment Display changes accordingly.

 

To reset the Max/Min memory inside the Status Monitor, first navigate with the DISPLAY and SELECT push buttons until the desired Max or Min value is displayed in the 7-Segment Display.  Then, press and hold the SELECT button for 5 seconds or more.  Observe that the displayed value flashes, then changes to become the same as the ‘live’ value.  Once reset, the new Max/Min value is updated when the ‘live’ value achieves a new extreme, either maximum or minimum.

 

The 7-Segment Display is only illuminated for 2 minutes of push button inactivity, after which time the display is extinguished.  To re-activate the display, touch either the DISPLAY or SELECT push button.  The first touch of either of these buttons, when the 7-Segment Display has extinguished, only illuminates the display and does not cycle to the next value as is the case when the 7-Segment Display is illuminated.

 

The 7-Segment Display power is derived from the Power Supply transformer, not the battery system.  Therefore, the 7-Segment Display is only illuminated when line power is available or when the Power Supply is operating in Standby Mode.  Battery connection alone will not illuminate the 7-Segment Display even though the Status Monitor may be operating from battery power.      

CONTROL  SECTION

 

The Control section of the Front Panel allows the user to put the Power Supply into Standby Mode from the Front Panel.  This feature allows local testing of the standby operation of the Power Supply.  The following photograph shows the Control section of the Front Panel:

            

LOCAL/REMOTE push button toggles the Power Supply between Local Control and Remote Control Mode.  The Local LED is illuminated when Local Control Mode is active.

            

The TEST/STBY push button initiates a test of the Power Supply by putting the supply into Standby Mode.  The Test LED illuminates when Standby Mode is active.  The Test can only be commenced when Local Control Mode is active.  The Test Mode is terminated when Local Control Mode is terminated, or after a 3-minute timeout period expires.

            

To use the Power Supply’s Control section, press the LOCAL/REMOTE push button and observe the Local LED indication.  Pressing this push button toggles the Control Mode between Local and Remote.  The Control Mode must be set to Local before the standby operation can be tested.  The Control Mode will automatically be restored to Remote Mode after 10 minutes of push button inactivity from the Front Panel.

            

To test the standby operation of the Power Supply, select the Local Control Mode (as described above), then press the TEST/STBY push button.  Observe that the Power Supply switches into Standby Mode and that the Test LED is illuminated.  To stop the test, press the TEST/STBY push button again.  After a line re-synchronization time, the Power Supply will exit the Standby Mode.

            

There are three ways in which the test may be terminated:

      1. Press the TEST/STBY push button to manually terminate the test

      2. Press the LOCAL/REMOTE push button to switch to Remote Mode

      3. Wait for the 3 minute timeout period after which time the test self-terminates

STATUS  DISPLAY  SECTION

 

The Status Display Section indicates the alarm type as detailed below.

            

The five major alarms are as follows:

     1. Battery voltage LOW (or battery circuit breaker is off)

     2. Output Voltage FAIL (under the following conditions) 

         Battery voltage OK

         Line voltage OK

         Standby Mode ACTIVE

     3. Output Voltage FAIL (under the following conditions)

         Battery voltage OK

         Line voltage OK

         Standby Mode INACTIVE

     4. Output Voltage FAIL (under the following conditions)

         Battery voltage OK

         Line voltage FAIL

         Standby Mode ACTIVE

     5. Standby Mode INACTIVE (under the following conditions)

         Battery voltage OK

         Line voltage FAIL

            

The two minor alarms are as follows:

     1.  Standby Mode ACTIVE (probably exiting standby mode) 

          Battery Voltage OK

          Line Voltage OK

          Output Voltage is OK

     2.  Standby Mode ACTIVE (typical power failure condition) 

          Battery Voltage OK

          Line Voltage FAIL

          Output Voltage is OK

            

The "Power On" LED is illuminated when the Status Monitor is powered and operating correctly.  Power is derived from both the Battery and Line Voltage inputs.

COMMUNICATIONS  SECTION

The Communications Section contains two (2) RJ-45 connectors wired in parallel to accommodate a daisy-chain of up to eight (8) Status Monitors using a single HMS (0022R7) compliant external transponder or modem.

 

The 777 Power Supply can be used with any compliant monitoring system.  Virtually all industry-standard systems with standalone transponders/modems can be used.

 

The "COMM OKAY" LED is illuminated when a valid communications link has been established with the external device.  The LED is extinguished after two (2) seconds of lost communications.

ROTARY  ID  SWITCH

 

To use the Status Monitor with an external HMS-compliant device (such as a Transponder or Modem) the user should plug in the CAT-5 data cable (8-conductor straight) from the external device to either one of the RJ-45 connectors.

 

Because there can be up to eight Status Monitors on one daisy-chained cable, the user must open the Front Panel of the Status Monitor and set the Rotary ID Switch to an appropriate Device ID.  Each Status Monitor must be set to a different ID.  The 10-  position Rotary ID Switch is shown in the following photograph set to ID = 1.

The Rotary ID Switch is set to identify the Device ID of this Status Monitor.  Valid positions are from 1 to 8 inclusive.

 

Switch positions 0 and 9 are invalid because they disconnect the Status Monitor from the communications link.
