Pentair Jung Pumpen 1225/2 BW, Instruction Manual

SETTINGS
If you wish to change a parameter in this system menu, you will
be asked to enter a password (4-digit number).
NOTE! The password is set to “3197” in the factory. If the pass-
word is changed and then forgotten, the device must be re-ac-
tivated by the manufacturer's customer service department. It
is not possible for the user to reset the system!
If more than about one minute passes in the system menu
without any entry being made, the control unit automatically
switches back to the standard display.
NOTE! Only the menu items relevant to Compli lifting systems
are described.
Level Control
The different types can be selected here. The switching levels
for the various lifting stations are already pre-set. In excep-
tional cases, however, they can be changed under this menu
item.
Timing
Max running time
The running time of the pump can be restricted to a maximum
duration. This function is necessary for short duration opera-
tion or intermittent duty operation (S2 and S3 operation) of the
pump.
The times are dependent on the type of pump and can be found
in the technical data provided with the pump. If the pump runs
continuously for longer than the time specified here, an alarm
will be triggered.
The maximum runtime monitoring is only active in ATEX mode
and can be reset after it has been triggered by the acknowl-
edgement button. If the acknowledgement button is not
pressed, an automatic reset occurs at the S2 time after 7 times
the triggering time and at the S3 time triggering after the S3
pause time.
• S2 time [Short-time operation]
When the pump is not submerged, it operates only for a pre-
set period (maximum running time 1 to 120 minutes). This is
to prevent the temperature of the motor from rising above its
maximal permissible operating temperature. The value for the
maximum permissible running time can be found in the techni-
cal data provided with the pump. The subsequent pause time
(restart lock-out), during which the pump remains switched off,
must be long enough to allow the motor to cool down to the am-
bient temperature. This is generally equal to the operating time
multiplied by a factor of seven.
• S3 time (intermittent duty)
The pump operates only for a short period before being
switched off again if it is not submerged. The switch-on and
switch-off times are expressed as percentages of 10 minutes,
e.g. for an S3 time of 30%, the pump is switched on for not
longer than 3 minutes and then switched off for 7 minutes. This
operating mode ensures that the pump does not overheat.
• Deactivated
The S2/S3 time monitoring can be deactivated here
Start-up delay
In order to avoid mains disturbances in areas with many pump-
ing stations, the control unit is equipped with a variable start-
up delay. The delay time can be set from 0 to 300 seconds.
Force activation
Alarm
In this menu all settings for the buzzer and the alarm relays are
made.
NOTE! In 9 V battery operation, the alarm only works with a
digital high water level sensor on terminals 27/28.
Acoustic alarm
If this function is deactivated, only the integrated alarm buzzer
is switched off.
Options: Off/on.
If a fault is acknowledged, the buzzer stops and the non-isolat-
ed relay drops out. However, the potential-free relay contacts
remain active. If the Acknowledge button is then pressed again
and the fault is no longer present, these relays are also reset to
their original position.
An external alarm acknowledgement is possible via terminals
14/15.
