6 MAINTENANCE
The following section describes the general maintenance and troubleshooting procedures for the
2810E-ATEX chamber communicator.
6.1
GENERAL MAINTENANCE
The 2810E-ATEX chamber communicator is designed to provide years of continuous, failure-
free service when properly used and maintained. One of the most important things that can
be done to extend the service life is to clean the communicator after use or when needed. If
the equipment is on an extended work program, have the tender clean the equipment during
slow work periods. Rinse off salt deposits with fresh water.
6.1.1
DAILY MAINTENANCE
Wipe off any accumulated salt or salt spray on the front panel using a clean, damp
cloth. Pay particular attention to where the various front panel components attach
to the panel. Inspect the outer case for any damage.
6.1.2
6 MONTH CHECK
Wipe off any accumulated salt or salt spray on the enclosure using a clean, damp
cloth. Pay particular attention to where the various front panel components attach
to the panel. Inspect the outer case for any damage.
Inspect the PUSH-TO-TALK BUTTON, rotary switches and volume controls for
smooth operation.
Perform the system test shown in section 5.1.
6.1.3
LONG TERM STORAGE
If the chamber communicator is to be stored for a period greater than 30 days, it is
recommended that it be stored in a cool dry location. If stored outside, the
communicator should be covered.
6.2
TROUBLESHOOTING
The following section will describe the troubleshooting procedure for several common issues.
If these sections do not cover your particular issue, if is recommended that the chamber
wiring be disconnected from the communicator and the check-out procedures in section 5.1
be conducted. If the chamber communicator passes the check-out procedures then the issue
is most likely in the chamber wiring.
6.2.1
UNIT NOT OPERATING
The most common reason that a diver communicator appears to be dead, when
the POWER SWITCH and SPEAKER SWITCH are turned on, is that the 24V
power supply is not on or is damaged.
If the 24V power supply and connections appear to be good and the communicator
fails the check-out procedure, then remove the (12) bolts holding the front panel
and carefully swing open as the components are connected to the Printed Circuit
Assembly (PCA) by a wire harness. Verify that the connectors on the PCA are
firmly seated. Check that the wire harnesses are soldered to the various
connectors, controls, and speaker. There should be no loose wires in the system.
Remove the fuse from the PCA. It is marked FH1 and is a cylindrical component.
