1.2 Symbols
The following symbols will be used in this document:
1.3 Product overview
RE7000 is a very efficient, high speed 12 000 N actuator developed to meet
the requirements in patient lift systems. It is equipped with a manual lowering
function, which allows lowering the lift by hand if the electrical power is not
available. It also has a “pull force protection” to prevent injuries.
In combination with REAC control systems for patient lifts (RCB15, RCB20
and RCB25), RE7000 regenerates energy back to the batteries when
lowering the lift, giving increased battery life time between charging.
1
RE7000 must be combined with a control system that can handle regenerative energy.
Using RE7000 with a not approved control system may lead to malfunction or personal
injury.

2.1 System and compatibility
Since RE7000 is so efficient and regenerates energy it must be combined with a control system which
can handle this generative energy, the following REAC control systems can all handle this. If another
control system is to be used this must be verified and approved by REAC.

2.5 Mounting instruction
RE7000 is easily mounted by using a pin with minimum Ø12mm together with a bushing. Without bushing
a pin up to Ø14mm can be used. RE7000 is as standard equipped with a stereo jack plug for easy
connection to REAC control systems.
Figure 2 Mounting of RE7000
Loads should act along the axis of the actuator. Off centre loads may cause binding and lead to
premature unit failure.
4
The actuator must not be subject to off centre loading, as this can damage the actuator
The mounting brackets must be capable of handling at least 30 Nm (22 ft-lb) torque
generated by the Re7000 between top and bottom mount. Failing to do so may lead to
subsequent malfunction or personal injury.
Figure 3 Load position
2.6 Operating instructions
The normal way to interact with the actuator is via the hand control (RHC15) and one of REACs control
systems. RHC15 has as default two speed operations, which makes it possible to run the RE7000 with
different speeds.
RE7000 has built-in end limit switches, which will immediately stop actuator movement when activated.
For smoother stops (patient friendlier) it is recommended that the actuator is stopped by releasing the
hand control button slightly before the mechanical end is reach to ensure the stop ramp to elapse.
2.7 Connectors
The RE7000 is equipped with a RCB-connector, which will serve as an identifier when used together with
a REAC control box. For futher information please refer to the user manual for the applicabel control box.
5
Do not use the actuator without inspection of authorized service personnel after the
manual lowering mechanism has been used2.
Using the actuator after the manual lowering was forced to be used may lead to
subsequent malfunction or personal injury.

3 Safety
3.1 Manual lowering
The RE7000 is equipped with a manual lowering function (patent pending), intended to be used in case of
an emergency when the normal lowering function is not working.
To lower the actuator manually, turn the top of the actuator clockwise and the lift will move downwards.
Figure 4 Manual lowering principle
3.2 Pull force protection
ISO 105353 specifies that if the spreader bar or lifting arm of the patient lift comes in contact with the lifted
person, the lifting machinery must not increase the load imposed to lifted person by more than 50 N.
RE7000 has a patented solution for detection of actuator pull force, which will immediately stop downward
movement when detected. Many patient lifts has a gearing of 1:5 and with that assumed it takes
approximately a force of 8,5 N at the end of the lifting bar for the actuator to stop, i.e. RE7000 will only
add a load of 8,5 N before the downward movement is stopped.
If not obvious that nothing is wrong with the actuator, for example battery to low
Hoists for the transfer of disabled persons – Requirements and test methods (ISO 10535:2006)
6
The actuator must not be subject to overload (> 12 000 N), as this can reduce the life
length of the actuator or subsequent malfunction and personal injury
The actuator must not be subject to a side load above 1 000 N, as this can cause
bending, which can lead to subsequent malfunction and personal injury.
4
5
3.3 Over load
The RE7000 is designed for loads up to 12 000 N and should not be used above this limit as it will reduce
the life length of the actuator and it can also lead to subsequent malfunction and personal injury.
An RE7000 used in combination with a REAC control system4 will be supervised for over load and if
detected by the control system the movement will be aborted and a warning alarm5 will be initiated.
3.4 Side force
RE7000 is designed primarily for a patient lift system in line with ISO
10535. When used in a patient lift, it should be marked with a label to
make sure that the user is aware of that the actuator should not be used
as a handle and it is not allowed to move the lift by holding on the
actuator tube or otherwise expose the actuator to side forces.

actuator to both end positions. When reaching the end position, the
actuator must stop without the button on the control device being
released.

4 Maintenance
4.1 Service intervals
To ensure proper and safe operation, regular service is required. When used together with REAC control
systems6 a service interval based on number of actuator cycles and/or calendar time can be configured
and a LED will be lit when service time is due. Note: there can be national norms for the applications in
which the actuator is used, that specify a certain service interval. This can easily be handled with this
configuration.
Between this service points regular maintenance and minor inspection must also be performed. Below
follows a suggested maintenance schedule.

4.3 Waste disposal
A RE7000 consist of several parts with different material, which means that they cannot be disposed as
one single item. It is recommended (at disposal) to disassemble and divide the product as much as
possible into feasible waste groups to be able to recycle the product in the most environmental friendly
way.
The following waste groups have been identified for the RCBs:
Some of these main groups can be divided into sub-groups, for example metal can be divided into iron,
stainless steel and aluminum and alloy steel. Plastic can e.g. be divided into ABS, PA, PE and POM.
All our plastic units are provided with an interior code for plastic types and fibre contents.

Short circuit
Alert indication LED will be lit.
Service needed.
Duty cycle protection
Duty cycle protection is a function
to protect the actuator motor from
overheating.
Alert indication LED will be lit,
during attempt to run the
actuator.
Wait until actuator “rest time” has
elapsed.
Hand control out of order
Nothing happens
Try to control the actuator via
control box panel.
The emergency stop
button has been
pressed.
The emergency stop is a normally
closed switch, which at activation
beaks all circuits (charger and
battery) and immediately stops all
movements.
Unlock the emergency stop
button by turning it clock wise.
Actuator not correctly
connected to control box
Nothing happens
Make sure actuator is properly
plugged into control box.
Actuator mix up
Wrong actuator will move.
If actuators are equipped with
RCB-connectors9, mix up will be
detected, movement will not be
allowed and alert indication LED
will lit
Make sure actuator/actuators are
connected properly.
Internal error
Alert indication LED will be lit.
If error remains after 10 s, service
is needed.
Actuator cable faulty
Check the cable and replace the
actuator if necessary
Charging ongoing
Operation is not allowed (and is
prevented by the system) during
charging, the yellow LED will
blink if any operation is
requested.
