Power Supply Batteries (Battery Models) - Tennant T290 Manuel D'instructions

between 220 V and 240 V. Similarly, models rated at 115 V can be used at between 110
V and 120 V. The frequency on the plate must always correspond to the mains voltage.
Make sure the mains circuit is suitably earthed and that the sockets (and any
adaptors used) ensure the continuity of the earth conductors.
Failure to observe these instructions could cause possibly serious damage to people

Power supply batteries (battery models)

Two different types of battery may be installed on these machines:
• tubular leak-proof batteries: the electrolyte level must be checked regularly. When
necessary, top up with distilled water until the plates are covered. Do not over-fill (5
mm max. above the plates).
• gel batteries: this type of battery requires no maintenance.
The technical characteristics must correspond to those indicated in the paragraph on the
technical specification of the machine. The use of heavier batteries could seriously
jeopardise manoeuvrability and lead to the brush motor overheating. Batteries with a
lower capacity and weight will require charging more frequently.
Batteries must be kept charged, dry and clean and the connections must be kept tight.
Follow the instructions below to configure the machine's software for the type of batteries
installed:
Mechanical drive version (B):
•
turn the machine on by pressing the button (fig. 5, ref. 3), wait 5 seconds and
make sure the display comes on.
•
press the brush buttons (fig. 5, ref. 3) and suction button (fig. 5, ref. 2) together for
at least 5 seconds. This accesses the battery setting menu.
•
press the suction button (fig. 5, ref. 2) to select the type of battery installed on the
machine "ACd" for acid batteries (tubular leak-proof batteries) or "GEL" (GEL
batteries).
•
Press together the buttons (fig. 5 ref. 2) and (fig. 5 ref. 3) for least 5 seconds, to
save the changes and exit.
Electric drive version (BT): set the machine software to the type of battery installed,
following this sequence:
•
turn the machine on by turning the emergency button key switch (fig. 5, ref. 15),
wait 5 seconds and make sure the display comes on.
•
press the brush buttons (fig. 5, ref. 3) and suction button (fig. 5, ref. 2) together for
at least 5 seconds. This accesses the battery setting menu.
•
press the suction button (fig. 5, ref. 2) to select the type of battery installed on the
machine "ACd" for acid batteries (tubular leak-proof batteries) or "GEL" (GEL
batteries).
•
Press together the buttons (fig. 5 ref. 2) and (fig. 5 ref. 3) for least 5 seconds, to
save the changes and exit .
