3.3.2 THE ELECTRICAL FUNCTIONS DO NOT
WORK
•
Does the relay click when you press the switch?
No:
Check if the fuse has blown (does not apply
to VELA Tango 300E/310E). The location of the
fuse is shown on the spare parts drawing for the
specific model. If the fuse has blown, replace the
fuse and check all wires thoroughly, as well as all
the electrical functions of the chair, e.g. up, down,
and charge. If the fuse has not blown, check that the
chair battery is charging properly (see
section 3.3.1
).
If the battery is charging properly, charge it for a
longer time, e.g. overnight.
If it does not charge properly, check that all wires
are connected as shown in the spare parts drawing.
If it still does not charge properly, contact VELA/
VELA Medical.
If the chair battery is fully charged, but the
functions are still not working,
replace the switch,
spiral cable, motor control or the entire actuator.
The motor control unit is an integral part of the
actuator. Otherwise, contact VELA/VELA Medical.
Yes:
Check that the chair battery is charging
properly (see
section 3.3.1
). If the battery is charging
properly, charge it for a longer time, e.g. overnight.
If it does not charge properly, contact VELA/VELA
Medical.
If the battery is fully charged, but the functions are
still not working, replace the battery, spiral cable,
motor control or the entire actuator, or contact
VELA/VELA Medical.
3.3.3 THE ELECTRIC LIFT GOES UP BUT WON’T
GO DOWN
Activate the end switch for downward lift function
by turning the adjusting screw a few times.
The adjusting screw is a galvanised screw that
requires a Philips screwdriver. It is located right next
to the column, near the bottom side of the seat
mechanism. See image:
(Does not apply to the VELA Tango 300E/310E)
3.3.4 THE ELECTRIC LIFT GOES DOWN BUT
WON’T GO UP
Check that the chair battery is charging properly
(see
section 3.1.1
). Check the voltage across the
batteries. Voltage must be at least 24V on a fully
charged battery. If it isn’t, replace the battery.
If this does not solve the problem, replace the
switch, spiral cable, motor control or the entire
actuator, or contact VELA/VELA Medical.
3.4 REPLACING COMPONENTS
Regular service and maintenance may require
parts of the chair to be disassembled to inspect
individual components and provide access to other
components, and to replace spare parts. Detailed
assembly instructions with text and images are
available on www.vela.eu, where they are divided
into model-specific instructions, which include both
standard configurations and accessories. Some
instructions also include video tutorials.
3.4.1 RECOMMENDED TOOLS
Only a small number of tools are required to
disassemble a VELA/VELA Medical chair. As a
minimum, it is recommended to always have the
following tools available in the toolbox:
• Allen key sizes 4, 5, and 6
• Small, flat-bladed screwdriver
• Philips screwdriver
• Shifting spanner up to 24 mm
• Fibre hammer/rubber hammer
• Lubricant, e.g. HSS2000
Several of the screws on VELA/VELA Medical chairs
are fitted with locking glue from the factory to
provide optimum safety for use. Therefore, only
use original screws when replacing components to
preserve locking glue in the intended locations.
3.5 ADJUSTING COMPONENTS
REMEMBER:
VELA/VELA Medical chairs are medical
devices and the chair is customised for the individual
user. Pay special attention to the position settings of
various parts, such as the armrests, before carrying
out any work on them. An occupational therapist
may have decided on a precise setting for the user,
so settings should always be set as they were before
maintenance.
