Audiable Alarms

Audible alarm signals are divided into two catagories. Each category represents a different level of alarm status. Catagory One Alarms represent normal or correctable operational alarms. Category Two Alarms are sounded in the event of abnormal operation This will provide the end-user a more detailed notification of the SVR’s status.

1.Category One Alarms:

•One long beep prior to a short beep, lets the user know the SVR is in an OVER LOAD, OVER CREST, or FAULT situation.

──− = SVR IS IN OVERLOAD OR OVER CREST

•When ON/OFF button pressed, the associated actions will be initiated and there will be one short beep.

−= WHEN SVR FRONT PANEL BUTTON DEPRESSED

•When the INITIAL SELF-TEST has been completed, there will be one short beep.

−= WHEN SVR FRONT PANEL BUTTON DEPRESSED

2.Category Two Alarms:

•Three short beeps: indicates the SVR output voltage is out of proper operating range.

−− − = SVR OUTPUT VOLTAGE OUT OF PROPER RANGE.

•Four short beeps: indicates the SVR output frequency is out of proper operating range.

−− − − = SVR OUTPUT FREQUENCY OUT OF PROPER RANGE.

•Five short beeps: indicates the SVR is in an over-temperature condition.

−− − − − = SVR INTERNAL TEMPERATURE TOO HIGH

3.If the INITIAL SELF-TEST cannot be completed after start-up, the SVR will sound the following alarms upon the stated conditions:

•Continuous rapid beeping for about 5 seconds and the SVR shuts down - Output voltage over range.

− − − − − − − − − − − − − − − − − − − − − − − − − = Output voltage over range.

•Continuous rapid beeping for about 2 seconds and the SVR shuts down - The SVR performed a DC start, but there is no output frequency set in memory.

− − − − − − − − − − = The SVR performed a DC start, but there is no output frequency set in memory.
