Display Alarms - Tennant T290 Manual De Instrucciones

At the end of charging with the
electronic battery charger, the
battery does not provide the
correct voltage (about 2.14 V
per element without load) and
only one or a few elements are
found to be discharged when
tested with a hydrometer
The electrolyte in the battery is
turbid
ACC / MAN : ACCelerator / MAN
Appears if the drive lever is pushed when starting or after an emergency reset.
The drive cannot be engaged until the lever is released.
POT : POTentiometer
This indicates a fault or breakage of the speed adjustment knob
Drive stops, release the drive lever and then activate it again.
If the problem persists, the knob may be broken.
Lim : Limitation
Appears when the MOSFET reaches the internal temperature limit.
Drive stops, release the drive lever and then activate it again.
If the problem persists, wait a few minutes to let the Mosfet cool down.

• taking the actual voltage
available at the socket into
account, make sure that the
connections of the primary of
the transformer inside the
battery charger are correct
(consult the battery charger
manual)
• make sure there is voltage
to the battery charger, that
the fuses are not blown and
that the current reaches the
battery; try charging with
another rectifier. If the battery
charger is not
contact the technical service
centre and indicate the serial
number of the
charger
