TROUBLESHOOTING GUIDE
8.1.
Condition:
AC Power Supply
–
Blue
“
Sonic Head
”
LED light is not blinking.
8.1.1.
Check to see if power is available at 120 Vac (or other line voltage) plug
using a voltmeter, tester, plug in lamp or other means. If AC line power is
on, then plug in the Quattro-DB
®
power supply and go to the next step.
8.1.2.
Verify the Quattro-DB
®
Power Supply is turned off, then disconnect the
Sonic Head cable from the power supply.
8.1.3.
With Sonic Head cable disconnected, turn the Power Supply back on.
Use a voltmeter to check the output voltage by measuring across pins 1
and 4 at Sonic Head 1 and Sonic Head 2. (Refer to pin diagram
Figure 8-1
below.) Verify that the output voltage from the power supply reads
approximately 39-44Vdc.
If no output voltage measured at the Sonic
Head Connectors and AC voltage is present, return the unit for service or
warranty repair. Do NOT open the power supply - no user serviceable
parts inside.
OPENING THE POWER SUPPLY ENCLOSURE VOIDS THE WARRANTY
!
If
you are returning a unit for service you MUST call our RMA department
in advance to receive an RMA tracking number.
8.2.
Condition: AC
Power Supply tripping circuit breaker.
8.2.1.
Disconnect the Sonic Head power cable(s) from the power supply and
reset the circuit breaker. If the breaker trips again the problem is in the
power supply or the Surge Protector/Extension Cord. Plug the power
supply directly into the outlet and reset the breaker. If the breaker stays
“ON”
the Surge Protector/Extension Cord is bad and should be replaced.
