Basic Service Checks
7-1
Chapter 7: Troubleshooting
The analogue compass repeaters are complex electronic devices, which
are not serviceable in the field down to the level of individual circuit
components. Defective units must be sent back to Sperry Marine for
repair.
7.1 Basic Service Checks
Field service personnel shall only limit troubleshooting to the basic ser-
vice checks given below.
All repeater types 5016-CA, -CB, -CC, -CD
•
Continuity checks of wiring connections.
•
Checks for short circuit or overload conditions or reversed polarity of
the external supply powers.
•
Software-aided troubleshooting using Sperry Marine’s SUSI applica-
tion, if explicitly instructed by Sperry Marine.
CAUTION
Risk of damage through unauthorized service
The housing of the bearing repeater 5016-CA is designed for increased
watertightness and shall therefore not be opened in the field.
Opening the housing in the field will diminish the watertightness and
may lead to condensation forming on the inside surfaces, especially the
top glass, at a later point in time.
Never open the bearing repeater housing in the field.
Always return a defective bearing repeater to Sperry Marine.
CAUTION
Risk of damage through unauthorized service
The analogue compass repeaters are complex electronic devices, which
are not serviceable in the field down to the level of individual circuit com-
ponents.
Defective units must be sent back to Sperry Marine for repair.
CAUTION
Risk of damage of electrostatic-discharge-sensitive components
The analogue compass repeaters contain electrostatic sensitive compo-
nents. Electrostatic discharge may permanently damage components.
When servicing an analogue compass repeater, take precautions to pre-
vent electrostatic discharge.
Avoid touching any of the electronic circuitry.
Note
The analogue compass repeaters are serviced and configured using the
Sperry Universal Setup Instrument (SUSI).
This tool is provided to authorized service personnel only and is gener-
ally not available to end-customers.
