Pentair Jung Pumpen 1225/2 BW, Instruction Manual

Page: 5 / 28

OPERATION
The control unit has a graphic LCD display. The data is evalu-
ated and updated at short intervals, which can sometimes look
like flickering. The backlighting is activated for a limited time
by pressing a button. The contrast can be changed in the sys-
tem settings menu item.
It is operated with a rotary knob and three membrane keys: an
acknowledgement button and manual-0-automatic buttons
for the pump(s).
The two LEDs show the operating status of the pumps:
• Continuous green light = Operational
• Green flashing - Pump in operation
• Continuous red light = Fault
• Red flashing - Fault, pump in operation
• Orange = Maintenance due
Operating modes
In addition to the automatic operating mode described above,
each pump can also be switched on and off manually using the
operating button.
The operating status of the control unit is shown in the display;
the existing operating mode is highlighted as a negative image.
MANUAL/ON
The pump continues to run in manual mode until a different
operating mode is selected. However, if there is dry-running
protection, this will take priority over the manual switching.
The pump must be switched off before it starts to draw in air!
Otherwise, the pump will require bleeding to discharge the air!
OFF
The pump is switched off and remains off until a different op-
erating mode is selected. It will remain off even if a high-water
situation occurs.
AUTO
The pumps are switched on and off by the control unit depend-
ing on the water level. However, if there is dry-running protec-
tion, this will take priority over the automatic switching.
NOTE! If the control unit is password-protected, the password
must first be entered under "Settings" to change the operating
mode.
WARNING!
For repair and maintenance work on pumps or control units, do
not use the "Off" function, but always de-energize the system
by unscrewing the back-up fuses or via a main switch and se-
cure against being switched on again!
NOTICE! If unusually large quantities of wastewater flow into
the unit (e.g. when a pool is drained), partially close the shut-
off valve at the inlet until the unit can operate normally again,
switching on and off, (S3 Intermittent duty, not pumping con-
tinuously, since this could overheat the pump motor).
Inspection
To maintain operational reliability, carry out a visual inspection
of the unit, including the pipe connections, once a month.
Faults / alarm
Faults are signalled via the red LED, a built-in buzzer, a non-
isolated relay "Alarm", a potential-free relay “Centralised alarm"
and a potential-free relay "High water".
The relay "Centralised alarm signal" can be delayed up to 60
minutes in order not to trigger an alarm if there is a short-term
high water level. The deployment of a service technician would
be unnecessary in this case.
The fault text is shown in the display and alternates with the
standard display text. If more than one fault has occurred, the
relevant messages will be shown consecutively in the display.
In addition, the high water alarm is reported to a separate po-
tential-free relay.
OPERATION
The standard display shows the operating mode of the control
unit, the switching status, the motor current and the level.
To enter the menu, turn the rotary knob to the right.
