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.
