Maintenance - Pentair Jung Pumpen HIGHLOGO Original-Gebrauchsanleitung

CAUTION!
Use only the manufacturer' s 9V NiMh rechargeable batteries!
There is a risk of explosion if dry-cell batteries or lithium bat-
teries are used!
NOTE! Check the function of the rechargeable battery at reg-
ular intervals! The service life is about 5-10 years. Note the
insertion date on the battery, and after five years the battery
should be replaced as a precautionary measure.
EMC
When used in connection with our standard submersible
pumps and accessories, and when installed correctly and used
for its intended purpose, the control unit meets all protective
requirements of the EMC Directive 2014/30 EU and is suitable
for domestic and commercial use when connected to the pub-
lic power supply network. If connected to an industrial power
supply network within an industrial facility, where the power
supply is provided by an in-house high-voltage transformer,
there may be insufficient immunity to interference.
QUICK TIPS FOR REMEDYING
FAULTS
WARNING!
Before carrying out any work: Disconnect the pump(s) and the
control unit from the mains by unscrewing and taking out the
pre-fuses, and take action to ensure that no one else can re-
connect them to the power supply.
NOTE! Work on the control unit must be carried out by qualified
electricians only!
• System does not work either in automatic or manual mode.
No mains power; check fuses and RCD switch, the operating
mode for the pump should not be set to "0".
• System does not work, mains power available, no alarm
Please check the submersible sensor, pressure switch and
air hose for faults.
• System does not work, "Pump motor protection" is displayed
The motor protection relay or the motor protection switch
has switched off. Check motor protection settings and set
the rated power for the pump. Acknowledge with the ac-
knowledge button and reset the motor protection switch by
hand.
• Motor protection shuts off after only a short time
Pump impeller blocked -> Clean (refer to pump manual)
Cutting system blocked -> Check (refer to pump manual)
Motor contactor does not switch through all phases->
Replace
Motor fault -> Call customer service personnel
• Backpressure, water rising slowly
Intake line blocked -> Clean and unblock.
• Pump delivers too little, high water alarm
Check gate valve in pressure pipe and open completely,
clean non-return valve and flush out pressure line.
• High water alarm and sensor logic
Submersible sensor dirty, air hose or pressure switch faulty
-> Clean or replace.
• Pump thermostat
Let the pump cool down, and acknowledge with the OK but-
ton.
• Sensor fault
Check safety barrier, transducer voltage and submersible
sensor.
• Display does not show any readings
No mains power; check fuses and RCD switch, switch on the
main switch if necessary.
• Green LED does not light up
No mains power, check fuses and RCD switch, switch on
main switch if necessary, operating mode of the pump must
not be set to "0".
• Red LED lights up
The fault is shown in the display; then confirm with the ac-
knowledge button.
• No access to the menu
Password incorrect.

MAINTENANCE

The dry-running protection is an important safety device for
explosion protection and must be checked for correct function
at least once a year, or twice a year in commercially used sys-
tems:
1. Switch on the pump with the Manual-0-Automatic selector
switch to "Manual". With duplex units, the test shall be car-
ried out successively with both pumps.
2. Observe sewage level in the pump shaft.
CORRECT: The pump is automatically switched off before
it "draws air" (listen for slurping noises). When the pump
is switched off, the ring housing of the pump must still be
completely under water. "Dry running" must be shown in the
display of the control unit.
INCORRECT: The pump is only switched off when it is
already "draws air" or it is not switched off at all.
NOTE! A specialist trained in explosion protection must
immediately search for and rectify the fault!
Switching off the pump too early, on the other hand, does
not pose any danger. However, the possible pump volume
is lower, which is why the pump switches on more often.
3. Finally, select the "Automatic" operating mode with the
manual-0-automatic selector switch. The pump must re-
main switched off until the water level for automatic switch-
on is reached again.
