Problem
Description
Cause
Solution
When switching to FILL
piston rod spins INWARDS,
switching to EMPTY piston
rod spins OUTWARDS.
Piston might block if moved to far over
its ultimate end position.
Wrong polarity of motor.
Change direction of motor
rotation by exchanging the
wires soldered directly to the
motor tags.
End switches of Piston Tank react not
analogously. Piston might block.
Wrong connection of end switches
or switch unit.
Verify wiring!
Dive system does not react
to FILL command.
LED5
blinks continuously (permanent
blinking).
LED6
is faint or does not glow
at all.
Main drive battery not connected to
switch unit or voltage already lower
than threshold voltage of battery
monitor when powering the system.
FILL command disabled due to
assumed weakness of main drive
battery.
Pay attention to correct
sequence when powering
activating the system:
1. Switch ON transmitter
2. Switch ON main battery
3. Switch ON receiver
Dive system does not react
to FILL command ANY
MORE.
LED5
blinks continuously (permanent
blinking).
LED6
is faint or does not glow
at all.
Battery voltage has fallen below
threshold value of battery monitor.
FILL command disabled due to
identified weakness of main drive
battery.
Charge battery.
LED5
blinks continuously when
operating Piston Tanks.
LED6
is bright
but faint or off when operating Piston
Tanks.
Main drive battery is fully charged!
Battery voltage is lower than
threshold value of battery monitor.
FILL command deactivated due to
assumed weakness of battery.
Threshold voltage is too high.
Lower threshold value by
slowly turning potentiometer
of battery monitor a small
step in CLOCKWISE
direction.
LED5
flashes in groups of four.
When submerging (filling of Piston
Tanks) the overpressure
compressed within the hull escapes
through a leakage. If pressure loss
becomes imminent, submerge mode
is disabled by pressure switch and
Piston Tanks are automatically set
to EMPTY.
Open breather so that
pressure within WTC is
equalized to normal
atmosphere. Allocate
leakage and seal
accordingly.
Significant difference between air
and water temperature creates an
under-pressure within the WTC.
Submerge command disables by
pressure switch.
Open breather so that
pressure within WTC is
equalised to normal
atmosphere.
LED5
is ON.
Transmitter not powered or
defective so that no signal can be
received.
Check transmitter and
transmitter battery.
Dive system does not react at
all.
LED1
to
LED4
of relais do not light up
when switching Piston Tanks to FILL or
EMPTY.
LED5
blinks continuously.
LED6
is OFF.
Fuse has blown due to mechanical
overload of Piston Tank(s).
Ensure free movement of
Piston Tank drive and
spindle. Replace fuse (10 A,
slow blow).
Water within WTC!
Condensation within WTC.
Difference between air and water
temperature leads to condensation
of humidity within WTC, mainly on
metal parts.
Open WTC until fully
dehumidified.
Piston Tank is leaking. Water is
discharged through bearing plate of
Piston Tank (possible but very unlikely).
Piston is leaking due to intake of
large amount of sand or other rough
particles. Piston is worn.
Unscrew bearing plate (to
which gears and motor are
attached), clean piston and
cylinder, grease piston or
replace. Refer to manual for
"Maintenance".
