1.2 Symbols

The following symbols will be used in this document:

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.

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

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)

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

will be supervised for over load and if

detected by the control system the movement will be aborted and a warning alarm

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.

RCB15. RCB20 or RCB25

Indicated by warning LED on the hand control or a sound warning. Must be configured pre-delivery.
