could be: “No Sonar Device Found”, this will indicate that the CPU does not connect to the sonar processor
card. “IF_DIAG” the sonar processor has detected an error and will not run. Cycle power on towfish
recheck error, if the error is still present check the cables running to and from the sonar interface card.
“HM_Sensors” this reports the 48 volts if this error is found check output of power distribution board in
towfish and also the power on the power amps.

Power Supplies
Several power supplies and voltage regulators are located throughout the towfish assembly. The main
ones are located on the Power Distribution board. The first supply converts the 400VDC tow cable voltage
to the ope48VDC supply. Other DC/DC converters running off the 48 volts generate the low level
operating supply voltages. No supplies are adjustable.
The following are the main voltage test points on the Power Distribution board:
SUPPLY
TEST POINT
RETURN
+5 VDC +/-0.2V
TP7
TP12
+12 VDC +/-0.6V
TP8
TP12
-12 VDC +/-0.6V
TP9
TP12
+27 VDC +/-0.6V
TP10
TP12
+48 VDC +/-2.0V

Other voltages to check on the SSB board and labeled as such are:
SUPPLY
+3.3 VDC +/-0.1
+5 VDC +/-0.2V
+12 VDC +/-0.6V
-12 VDC +/-0.6V
