Failure to comply with these instructions may result in accidents involving personal injury.
Failing to follow these instructions can result in the product being damaged or destroyed.
Useful tips, recommendations and information for efficient, trouble-free use.
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.

2 Technical data
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.
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.

2.5 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.

5
Figure 3 Load position
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.
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.

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
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.
3.2 Pull force protection
ISO 10535
3
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.

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 system
4
will be supervised for over load and if
detected by the control system the movement will be aborted and a warning alarm
5
will be initiated.
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
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.
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.
