6. Information on specific controls
The ACC (Attendant Control Compact) is fitted to advanced hospital and patient care beds for use where
patient positioning must be carefully controlled by medical staff.
1. ACC (MEDLINE

2. ACK (MEDLINE

)
With the OpenBus
TM
system it is possible to use ACK membrane front covers as attendant control or hand controls integrated in the bed side rails.
There are two different variants of ACK: ACK1 and ACK3.
The ACK1 is a single membrane front cover, whereas the ACK3 comes with two membrane front covers, typically used on an inside side rail and an
outside side rail.
Features and Options:
• Straight cables: 1250 mm, 1800 mm or 2500 mm
• The standard ACK colour is grey (RAL 7035)
Usage:
• Operation temperature: +5 °C to +40 °C
• Storage temperature: -10 °C to +50 °C
• Compatibility: Compatible with LINAK control boxes.
Please contact LINAK
• Relative humidity: 20% to 80% - non-condensing
• Atmospheric pressure: 700 to 1060 hPa (3000 m)
• Meters above sea level: Max. 3000 meters
• Approvals: IEC60601-1
ANSI/AAMI ES60601-1
CAN/CSA-22.2 No 60601-1
Generel information
For LINAK standard ACKs, the following is applicable:
• Adhesive for the standard ACK is 3M 7955
• For information re. suitable and unsuitable surfaces, please see 3M’s
webpage
• Standard recommandation for curing time is 72 hours
• The customer is responsible for correct mounting on suitable surfaces
Recommendations
• The customer responsibility includes making a proper design of the cable strain relief inside the side rail panel.
• The customer should consider the existence of vibrations when defining and specifying the housing, i.e. we recommend the customer to carry
out a vibration test on the final product.
• The customer must ensure a proper IP rating/test
• The customer must ensure proper drop testing according to IEC60601-2-52 §201.15.3.4.1. In this clause there is an additional reference to
IEC60601-2-31.
• The customer is responsible for correct mounting of the PCBA. Among other things, it means
- ensuring proper and safe mounting of the PCBA into e.g. the side rail
- ensuring proper and correct mounting between key pad connection tails and the ACK PCBA
- ensuring proper and correct mounting of the key pad
- the customer should consider proper precautions against ESD (Electrostatic discharge).
• When handling ESDS (Electrostatic Discharge Sensitive) devices – e.g. during transport, storage, handling, production or mounting in an
application - exposure to harmful ESD must be avoided.
• Consider proper creepage and clearance measures to fulfil IEC 60601. With One MOPP (One Means Of Patient Protection / Secondary
side of the actuator system)
• It is not recommended to dismount the membrane front cover after mounting as this may cause damage.
The ACL (Attendant Control Lock) box is a one turn button box for various applications where the patient
positioning must be carefully controlled by the medical staff.
The ACL disconnects all functions on hand control either by means of turn button or turn key.
3. ACL (MEDLINE

CARELINE

)
The aim is to minimise the risk of unintended activation of an actuator and hereby minimising the risk of “squeezing”.
Due to ESF (Electronic Safety Function), the ACL / FS has to be operated using a certain technique in order to
activate the switch.
It is necessary to “double click” to start the system :
• Foot pressure must be applied for a short period of time, from 30 ms to 250 ms.
• Then briefly lift the foot from (max. 40 ms to max. 550 ms pause), followed by a normal activation.
• After an activation attempt without success, a pause of min. 1. sec. is required before a new attempt.
