Alarm Contacts; Rechargeable Battery - Pentair Jung Pumpen HIGHLOGO Original-Gebrauchsanleitung

ENGLISH
pump cable wires marked 30/32 (motor thermal contacts)
must be attached to terminals X3-P1 30/32 for pump 1 and X4-
P2 30/32 for pump 2 separately.
NOTE! If pumps without a winding thermostat are connected,
an insulated wire bridge must be laid from terminal 30 to 32.
If the rotating direction is correct, the start-up jolt of the pump
is in the opposite direction to that shown by the rotational di-
rection arrow located on the motor housing. If the direction of
rotation is not correct, the two phases of the pump cable must
be reversed on the control unit.
WARNING!
Before starting up for the first time, check that the protective
measures function properly!
Motor protection relay / switch
The pump is monitored by a motor protection relay for single
units and by motor protection switches for duplex units. When
the motor protection trips, the pump is switched off and an
alarm is triggered at the same time.
In Ex systems, the message is stored in a zero-voltage safe
manner, even without a battery.
Once triggered, the motor protection must always be reset by
pressing the acknowledge button before the pump is restart-
ed. The motor protection relay is set to automatic reset, only
the motor protection switches in duplex units must be reset
mechanically in addition.
Without ATEX mode, the motor protection relay is automati-
cally reset. The motor protection switch must also be reset
mechanically in this mode.
NOTICE FOR HIGHLOGO 2-00! The motor protection switch
only protects against a short-circuit in the pump. The current
at the motor protection switch must therefore be adjusted to
the maximum setting.

Alarm contacts

• Non-isolated alarm relay (230 V AC, fused with 2A slow-
blow), terminals N/X2 (NO contact) or N/X3 (NC contact)
The relay makes contact if there is a fault (operating current
principle).
• Potential-free centralised alarm relay
The changeover contact (40-41-42) can be loaded with
max. 5A/250V AC. The relay drops out with error and power
failure (quiescent current principle).
• Potential-free high water relay
The changeover contact (50-51-52) can be loaded with max.
5A/250V AC. The relay makes contact if there is a fault
(operating current principle).
Level detection
If the control unit is operated with an analogue level detec-
tion, this must be connected to terminals 9(+) and 10(-). NOTE!
Check that the poles are connected the right way round!
If the control unit is operated with a digital level detection, the
switch for the base load is connected to terminals 21(-) and 23(+).
Because this is a NC contact, the polarity is unimportant here.
The second level sensor is to be connected to terminals 27/28.
It is used to detect high water and the peak load function.
When operating with three submersible ball contact switches,
the high water function and peak load functions are separate.

– Base load ON/OFF terminals 21 / 23
– Peak load ON/OFF terminals 24 / 25
– High water alarm terminals 27/28
With separate submersible switch for -OFF-
– Pump(s) OFF terminals 1 / 2
– Base load ON terminals 21 / 23
– Peak load ON terminals 24 / 25
– High water alarm terminals 27/28
In explosion protected areas, however, submersible ball con-
tact switches must be connected via an explosion protected
auxiliary switching module.
Level measurement with the static air
pressure system
If the static air pressure system is used for measuring the wa-
ter levels (using switch or pressure switch), two measurement
systems are usually used. The first system is used to detect the
base load; the air hose is connected to the base load switch
or to the static pressure sensor module. The second meas-
urement system is used to detect high water levels (when the
pressure sensor module is used as a redundant system) and
must be connected to the high water switch. The redundant
system switches the pump(s) on in the event of an error. The
maximum permissible air hose length is 20 m.
It is important that the hose is laid at a slight downward gradi-
ent from the control unit to the shaft.
Air-pressure sensors
NOTE! The hose connections on the bell and pressure switch
must be absolutely airtight! Use permanently elastic sealant
for sealing.
The switch-on level is determined by the installation heights of
the air-pressure sensors in the collecting chamber.
The hose lines must be laid in an ascending manner along the
entire course to the control unit in order to avoid water pockets
caused by condensation water! Water in the hose will cause
the switching points to be displaced. Also, if the hose is ex-
posed to frost, the water could freeze and cause the switching
system to break down!
The hoses may have a maximum length of 20 m. Existing hoses
must not be extended due to the danger of leaks, but must be
replaced with hoses in one piece.
Connect the static pressure system for "base load" to B1, and
the "Alarm/peak load" (blue hose) to B2 on the control unit.
Dry running
In potentially explosive systems the pump must not run dry.
Separate dry running protection must therefore be installed. A
submersible switch is connected to terminals 18/20 via a safe-
ty barrier. The submersible switch remains closed if there is
a high water level. If the water level sinks to the height of the
pump ring housing, the submersible switch opens and both
pumps are switched off.

Rechargeable battery

The control unit can be fitted with a 9V NI-MH rechargeable
battery. In 9 V battery operation, the alarm only works with a
digital high water level sensor on terminals 27/28. At the same
time the jumper "BRX" must be set if the buzzer is to sound.
