7-Troubleshooting pulseEKKO PRO

Figure 7-2: Make sure fibre optic strain relief colour matches the receptacle door colour (grey to grey and black to black).
Reset the System by Powering Down: If the connections are OK but the error persists, try powering
down the system completely. This power down will include turning off the DVL and Control module as well
as the transmitter and receiver and fibre optic beeper/trigger (if present). Then power everything back on
and see if the system runs.
7.1 Power Supply
Another common problem that can occur while trying to run a system is insufficient power. The battery
may be dead or have a low voltage. If the system is being run from AC, there may be a problem with the
AC power supply or adapter.
7.1.1 DVL and Control Module Power Requirements
The DVL and pulseEKKO PRO control module are designed to operate from a 12 volt DC, 3 to 4 amp
source such as batteries or power supply (See Figure 2-34 on page 25). The input voltage tolerance is
10.2 volts to 15 volts. The standard belt battery supplied with the system (See Figure 2-34 on page 25) is a
7 Amp-hr. battery that should power the DVL and the control module for approximately 8 hours.
If there is enough power to run the DVL, the upper red LED on the front of the DVL will light up when the
battery is plugged into the system. If this light is on and the DVL boots up, runs and displays the main
menu then there is sufficient power for the DVL.
The control module is only powered when data collection begins so there needs to be sufficient power in
the battery for the control module.
If the DVL turns on, the voltage of the battery can be monitored from the main menu (See Figure 2-36 on
page 27).
If the battery voltage is less than about 10.2 volts, the DVL may not turn on and the upper red LED will
flash or not illuminate.
