supply and perform lockout procedures so it cannot he turned on

again.

• Do not bridge fuses or make them ineective. When changing

fuses, make sure you use the correct amperage.

• Keep moisture away from conductive parts. If you do not, this can

cause short circuit.

Control unit - SCU

WARNING

Electrical shack hazard

Check the mains voltage corresponds to the nominal values on

the product label.

• Ensure that power cables cannot become pinched or damaged.

• Warning regarding electrical shock owing to damaged plugs or da-

maged network cables. Never touch a damaged network plug or a

damaged network cable when the SCU control unit is running,

since the SCU control unit is supplied with 120 VAC or 230 VAC.

• Ensure, before you pull a defective plug out of the plug socket,

that the SCU control unit is disconnected from the power supply.

WARNING

Unintended, uncontrollable movement

• Due to a defect of a component, an uncontrollable movement of

the connected actuator[s) can occur.

• In worst case RAM or ROM failure can lead to a false or auto mo-

tion. This kind of failure has a low failure probability and it occurs

in such a way that a motion is started.

• If the button of the hand switch sticks when releasing it and the

user doesn't press the button for the opposite direction (⮑

chapter 7.3) then an auto motion occurs.

WARNING

Specic dangers during cleaning or washing the control unit

SCU

The control units are designed to comply with IPX4.

The cleaning or washing with water including chemical additives

must be pH-neutral. Excessively acidic or alkaline washing water

can destroy metal and plastic components of the control unit.

Manually and mechanically operated high-pressure steam

cleaners must not be used. Only isopropyl alcohol cleaning

agent may be used for disinfecting by manual wiping.

A SCU control unit must never be washed in a washing machine

or other equipment. The control unit would be destroyed by the

penetration of liquid.

The plastic housing must be checked periodically (every six

months) for mechanical damage (cracks).

WARNING

Injury due to cracks and related openings in the housing of the

actuator and/or its accessories:

If the housing is damaged due to stock, breakage or heavy wear,

stop using the device and follow the dismantling instructions.

incorrect operation. Incorrect operation can endanger people in

the danger zone or objects.

• Before pressing a button on the operating device, ensure that you

press the right button.

• Take appropriate measures to ensure that the operating device

cannot be operated.

CAUTION

No function is considered as a safe condition.

CAUTION

The SCU control unit is only suitable for interior applications

and must not be subjected to weathering, strong UV radiation or

corrosive or explosive air (⮑ Ambient conditions).

The SCU control unit may only be operated when the safety

protective cover (⮑ g 8) is mounted.

CAUTION

Failure of the control unit due to interruption to the mains power

or an electronic defect should not pose any hazard to the

patient, to the operator or to the servicing personnel.

Ewellix actuators should be operated in accordance with the

application specied on the type label.

The nominal data for the actuators and the control unit must be

veried at the same time of installation. The ratings on the data

should not be exceeded. If this information is disregarded, the

actuator and the control unit will be damaged irreparably. Risk of

personal injury remains.

CAUTION

Any overload on the control unit will trip a temperature switch

in the mains transformer. After cooling of the transformer, the

thermal protector will reset, so the control unit SCU is ready

again to control the actuators.

CAUTION

Electric shock hazard

Take care about damage to the SCU from water sprays. The

control unit SCU is splash-proofed according to IPX4. Prevent

the SCU from being subjected to water sprays or hosing during

the operation time.

NOTICE

Prolonged overload will result in irreparable damage to the

control unit.

2.4.2 Specic dangers SCU with

batteries

Replacement batteries should only be ordered from Ewellix,

since they are a special type. The old batteries must be

properly disposed of. The user’s maintenance personnel

must be given instructions by the ultimate manufacturer on

opening and closing the battery compartment lid and on re-

placing the batteries.

WARNING

If unintended movements can cause serious injury, additional

protective means must be installed to stop or avoid such

movements.

WARNING

Disconnection from the mains power supply will not prevent

movement of the actuators in case of an electric defect while

batteries are connected.
