7.3 Control Module Related Errors
Control Module related errors are generated whenever the DVL fails to communicate with the control
module for any reason.
The most common causes of these errors are the following:
a) Control Module-to-DVL connection is loose or faulty.
b) The Control Module is damaged.
The following checks should be carried out.
a) With the system completely hooked up turn the DVL and control module OFF then back ON
again and retry the system.
b) If you are still having problems running the radar system, the problem is either with the control
module itself or the DVL. The control module or DVL may need factory service.
7.4 Receiver Related Errors
If a receiver error is encountered, check that the receiver is turned on, that the batteries for the receiver are
properly charged and that the receiver to control module fibre optic cable is not damaged and is properly
connected.
Perform the following checks:
1) Check that the red POWER light on the top of the receiver is ON. If not, then press the ON/
OFF switch once to see if the light comes ON. If it does, retry the system to see if it will run. If
the red POWER light still does not light up or flashes, check to make sure the batteries are fully
charged.
2) Check the condition of the fibre optic cables. Look for any sign of stress or damage. Replace,
if possible.
If neither of the above solutions solve the problem, contact Sensors & Software Inc.
7.5 Transmitter Problem: No Signal on Screen
In Scope mode try the Auto timezero search. Keep the antennas about one antenna length apart.
If the pulse still cannot be found do the following checks:
1) Make sure the transmitter batteries are properly charged and connected.
2) Check the condition of the single fibre optic cable to the transmitter, looking for any signs of
stress or damage. Replace or repair if needed.
3) Check that the brass antenna sockets in the bottom of the transmitter and receiver and that the
brass antenna pins in the top of the antennas are properly tightened. Also check that there is a
good contact between them.
