charger
If, having followed the correct steps
up to connecting the charger to the
battery and the mains and
switching on, the charger does not
behave as expected, then check for
the following (Fig. 51):
No lights
The mains supply is not reaching
the charger, check that the mains is
working, that the mains plug and
fuse are in correct working order.
Otherwise consult: Sunrise Medical
or your local Sunrise
Medical
dealer.
Flashing lights
This indicates that the battery
voltage is too low (over discharged
batteries or batteries of the wrong
voltage or type).
Consult Sunrise Medical or your
local Sunrise
Medical
dealer.
The charger has a designed in
safety feature which prevents it
from commencing to charge if the
battery voltage is lower than
16 volts for a 24 volt battery. This
low voltage battery condition is
usually the result of very deep
discharge or totally worn out
batteries.
Yellow mains on light only
Disconnect the mains supply.
If still lit, the battery has been
connected the wrong way round.
Check all connections to the battery
terminals are the correct way
round.
If the light goes out, the battery
is not properly connected or
may be flat. Check the integrity
of the battery connections and
consult Sunrise Medical or your
local Sunrise Medical dealer.
