pressure switch TDS DSP
– The pump operates continuously or frequently switches
on or off.
– The LEDs
Power
(5),
Failure
(6) and
On
(7) are
illuminated (green / yellow / orange).
– Turn pressure setting screw 2.5 times towards the
minus sign.
– The pressure is reduced by approx. 0.5 bar.
Shutdown
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
If you like to disconnect the pressure switch from the water
network, (e.g. for cleaning, maintenance or storing during
winter), proceed as follows:
1. Disconnect the pressure switch from the power supply by
plugging the mains plug out of the mains socket.
2. Afterwards, disconnect the power supply of the pump from
the pressure switch.
3. Open a tap that is connected to the pressure switch to
release any remaining water pressure.
4. Disconnect the connection on the water outlet of the
pressure switch. Afterwards, disconnect the connection on
the water inlet of the pressure switch.
5. Empty the pressure switch (and your pump as well).
Carefully dry pressure switch and power cable.
Note
During winter, store pressure switch (and your pump)
in a dry room and protected against frost.
Errors and faults
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
•
Switch off the device.
•
Hold onto the mains plug while pulling the power cable out
of the mains socket.
The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.
The connected pump does not start operating:
•
Check the power connection.
•
Check the power cable and mains plug for damage.
•
Check the on-site fusing.
•
Check the necessary initial pressure of the pump.
•
Check whether enough water is available and make sure
the water can be sucked by the pump without any
problems.
•
Check whether the LED
Failure
(6) is illuminated. If so,
press the
Reset
(4) button. If the pump is still not starting
to operate, make sure that the water in the water lines can
flow freely. If necessary, fill the pump with water (dry run).
If this does not help, check the pump for its correct
function and check whether the pump capacity is sufficient
(see Start-up chapter).
•
Check whether the power supply of the pump is switched
on. The LED
On
(7) on the pressure switch should be
illuminated.
The pump runs permanently and does not stop operating
•
Possible leakage in the system that exceeds the minimal
water flow rate of 1.2 l at which the pressure switch
switches off the pump. Check the distribution network for
leakages and remove any existing leakages.
The connected pump starts to operate several times and
stops again
•
Check the water line for leakages and remove any existing
leakages.
The pump runs permanently and does not stop operating
•
Possible leakage in the system that exceeds the minimal
water flow rate of 2 l at which the pressure switch
switches off the pump. Check the distribution network for
leakages and remove any existing leakages.
Your device still does not operate correctly after these
checks?
Please contact the customer service. If necessary, bring the
device to an authorized specialist electrical company or to
Trotec for repair.
Maintenance
Activities required before starting maintenance
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.

of the mains socket.
Notes on maintenance
Inside the device, there are no parts that need to be maintained
or lubricated by the user.
Cleaning
•
Clean the device with a soft, damp and lint-free cloth.
Protect electrical components from moisture. Do not use
any aggressive cleaning agents such as cleaning sprays,
solvents, alcohol-based or abrasive cleaners to dampen
the cloth.
