13 Troubleshooting
All possible errors are listed in this table.
Problem
Possible cause
Remedy
The changeover unit does not change
even though the battery connected is
empty and a full battery has been
connected to the other side.
After connecting the new chlorine tank, the OK
button in the cylinder symbol was not pressed.
The OK button in the cylinder symbol must be
pressed after changing the cylinder. The display
changes from red to green.
The voltage supply has been interrupted. All LEDs
are off.
Reactivate the voltage supply.
The changeover unit changes during
normal operation, even though the
chlorine tank is still full.
The "residue discharge" function is active.
Recognisable on the illumination pattern of the
LEDs. The LED of the empty cylinder flashes green.
No fault has occurred. See the functional descrip-
tion in chapter 8.2.3.
If this is desired, deactivate residue discharge on
switch SW1.
The maximum supply volume from the battery was
exceeded.
n
Insufficient chlorine tanks connected
n
Not all tank valves were opened.
n
Short-term strongly increased extraction due to
shock chlorination
n
A number of tanks are already empty
n
Connect sufficient chlorine tanks and open the
valves
n
Remove simultaneously from both tank
batteries for a shock chlorination (see figure
7.3.2)
n
Should the tanks be emptied at differing rates,
arrange for the adjustment of the vacuum
regulator and activate the residue discharge
function.
The yellow LED valve symbol flashes
n
The switch on the motor is set to MAN.
n
A cable connection between motor and control
has been interrupted.
n
The position switches in the motors are
misaligned.
n
Move the switch on the motor to AUTO. Press an
OK button.
n
Check whether plugs on the motor are loose.
If you do not experience any success: inform
Lutz-Jesco service.
A number of LEDs flash simultaneously
The control is in test operation because switch SW2
is set to ON.
Switch SW2 to OFF.
The operating display on the control is
mirror inverse to the hydraulic function.
The switch direction was changed during
maintenance. Either the ball in the ball valve is
fitted back to front or the motor was inserted 180°
incorrectly.
Check whether the arrow on the coupling matches
the switching function of the ball valve.
Repeat the fitting of the maintenance and check its
correct alignment.
