Prior to first use of LINAK batteries, please make sure that they are being charged 24 hours in order to reach proper function and prolong the lifetime of

the batteries .

Warning

Please observe the following maintenance, replacement, and disposal requirements to ensure a safe and reliable operation .

Maintenance of batteries

The batteries are to be replaced after 4 years at the latest . Perhaps earlier, dependent on the pattern of use . Frequent and high-powered discharges reduce

the battery life . For an optimum lifetime the product must be connected to the mains voltage as often as possible . It is recommended that the batteries

are to be charged at least every 3

function at least once every year .

Replacement of batteries

The batteries must only be replaced by the same type of batteries or mechanical and electrical equivalent types .The batteries must be new or maintained by

means of charging at least every 3

codes may lead to a severely reduced life time expectancy .

Before mounting ensure that the battery set is correctly connected, compare with the drawing in the battery room, and check that no connectors are loose .

Warnings

From the factory the battery room is hermatically separated from the electronics room . When replacing the batteries this separation must not be

damaged or modified as this may allow penetration of battery gas into the electronics room with risk of explosion .

When replacing batteries in waterproof products (IPX5 and IPX6) precautions must be taken that the sealing material (silicone ring or joint filler)

is not damaged and that it is correctly placed in the groove . Hereafter the screws in the cover are to be fastened with appox . 1 Nm . If the seal is

damaged it must be replaced by a new silicone string (LINAK article no . 0008004 for a roll of 100 metres) .

Disposal

The batteries, which are lead-acid batteries, can be returned to LINAK or disposed in the same way as car batteries .

Warnings

The battery room is supplied with ventilation that ensures correct and necessary airing of the battery room . This airing must not be blocked or

covered as a positive pressure may occur with risk of explosion .

If the product has been exposed to mechanical overload (lost on the floor, collision/squeezing in the application or a powerful stroke) the product

must be sent to an authorised workshop for control of the hermetic separation between the battery and electronics rooms .

Using control boxes with speed control

The common way of carrying out a speed control of the actuators is by using PWM, switching the motor on/off at a high frequency .

In rare cases, while switching the motor on/off, we have experienced that the coupling between the actuators and application frame and ground is too

high, thus generating a slight current noise which exceeds the allowable EMC limits . The current in question is extremely low and is in no way related to

any personal or patient risk .

The coupling is defined by the mechanical layout of the application, and no real guidelines can be given . Using plastic bushings or similar can improve the

application .

If an application faces this issue, it can easily by solved by connecting ground of the CB box to the application frame-, through a cable with built in serial

connection of a resistor and a capacitor .

The EMC test defined in IEC60601-1-2, applicable for all medical products, will show if this is an issue concerning the specific applications .

If you need more information or have any issues on this subject, please contact your LINAK A/S Sales contact .

Design criteria when using a customized CB

When using a customized CB together with a LINAK actuator, the interface connection between the CB vs . Actuator as well as the purpose of the actuator

(with or without feedback) must be considered .

Actuators with feedback

E .g . potentiometer solutions have certain technological characteristics due to the design that might cause quality issues if used outside the specification

range .

The connection interface

The connection interface is not only the compatibility of the plug types used, e .g . male mini-fit to female mini-fit plug type .

It is also considering the contact transition, i .e . the cable as well as the cable connector, the connecting plug, the material surface of the plug PIN, the

soldering of the PCB plug connector etc .

When however using a LINAK Actuator with feedback AND having a bad connection interface towards a Customized CB – LINAK only

guarantees the feedback voltage to be within 500 mV (+/- 250 mV).

month - otherwise will the batteries have reduced capacity due to self-discharge . It is recommended to test the battery

month . The batteries, which make a set, must be supplied with identical production codes . Mismatching of production
