Misc. on the MJB system
Warranty and service life
The LINAK warranty covers manufacturing defects in the products, starting from
the date of manufacture. There is 18 months’ warranty for MEDLINE and CARELINE
products. The warranty is limited to the value of the LINAK product.
LINAK’s guarantee is only valid so far as the products have been used and
maintained correctly and has not been tampered with. Furthermore, the products
must not be exposed to violent treatment. In the event of this, the warranty will be
ineffective / invalid. LINAK’s warranty is only valid if the system is unopened and has
been used correctly.
All LINAK products are designed to have an optimum service life as a matter of
course, but the expected service life in a specific application is very dependent on
how the products are used.
Maintenance
• The LINAK products must be cleaned at regular intervals to remove dust and dirt
and inspected for mechanical damage, wear and breaks.
• The LINAK MJB is a closed unit and requires no internal maintenance.
• IPX6 is waterproof.
• Make sure that the plugs in the MJB are correctly fitted with O-rings before
washing.

MJB - GATEWAY variant, 504-01 & 504-02 :
The MJB is a simple gateway interface, which can connect the bed to the infrastructure
of the hospital or nursing homes. The Gateway can be used in combination with an
Out of Bed Sensor, which makes it possible to indicate if the patient leaves the bed.
The Gateway can also be used as a service/nurse call system. Please note it is only to be
used as a guided system, not for emergency issues.
Standard functionality:
The MJB - Gateway consist of two relays, which are connected through Port 5 on the
MJB. This can be made with the special cable 0964140 (Modular plug - Open end)
There are as standard 2 configurations, 504-01 and 504-02, see description on the
next pages.
Relay1: NC (normally closed) = Pin 2 + Pin 1 / NO (normally open) = Pin 2 + Pin 3
Relay2: NC (normally closed) = Pin 5 + Pin 4 / NO (normally open) = Pin 5 + Pin 6
Relay 1 is NO when connected to the mains and NC when no mains, this means
the relay is “active”, when connected to the mains (closed loop). The Closed Loop
principal is to ensure that an alarm is sent if power is missing on the bed. When the
mains is disconnected (power is missing), the relay will go from NO to NC, which will
automatically result in an alarm (status indicator) on the OpenBus™.
Relay 1 can be activated via the patient control (Key1 / Key4) or the attendant control
(Key2 / Key3). When a key is activated, the relay will switch state from NO to NC for 2
seconds. After 2 seconds the relay will automatically change state from NC to NO.
The status of the relay is indicated on the OpenBus™ and can be used for switching
on an LED.
Relay 2 is as default NC, with or without mains, (Open Loop)
Relay 2 can be activated via the patient control (Key 1) or the attendant control (Key 2
/ Key 3).
When the relay is activated, it will switch from NC to NO for 2 seconds. After 2
seconds the relay will automatically change state from NO to NC.
The status of the relay is indicated on the OpenBus™ and can be used for switching
on an LED.

Features:
• Add-on value for hospital & care bed
• Compact and functional design which allows easy mounting
• 2 connections, Port1 OpenBus™ connection / Port 5 Gateway
• Colour: Light grey RAL 7035
• Protection class IPX6
• Connection to OpenBus™ control box via modular plug cable, 6 wires
• Modular plug to Open end, see precautions.
Options (special article):
• Customised SW:
It is possible to define the OpenBus™ signals to be used for activating the relays
and / or change the alarm indicator, so that it fits to the customers system. Please
contact your Sales Engineer at LINAK A/S for further information.
Usage:
• Compatible with all LINAK OpenBus™ Control Boxes, light & full
Contact rating :
• Max continuous current : = 1A
• Maximum switching voltage : = 125V (DC) / 125V (AC)
• Maximum switching capacity : = 24W (DC) / 62,5VA (AC)
• Contact resistance : < 100 m
Current consumption:
• V bus 8V : = 9 mA
• V permanent 40V : = 14 mA
• Approvals: LINAK and UL International DEMKO A/S are currently in the process of
certifying the MJBX0X, re. UL60601 and EN60601-1
By using the variant 504-02 relay 2 will be controlled by the MJB variant 505/506 with
switch input.
Alarm 1 = Switch input S2 (OoBD alarm) / Alarm 2 = Switch input S1
When using this combination, is it important to have the MJB 505/506 connected to
the system all the time. If it is not connected, the Gateway MJB will see it as an alarm
and the relay will be activated. The Gateway MJB is “scanning” the OpenBus™ system
every minute for an alarm.

Precautions:
• Always use locking mechanism and O-ring
• Sockets not used must be fitted with blind plugs to ensure IP Degree
• When using the modular plug with open end, is it up to the customer to maintain
the IP degree.
• If the MJB – Gateway is used as open loop, there is a risk of not sending an alarm,
when no mains are connected. The MJB – Gateway will only send an alarm if
mains is missing, when using a Closed Loop (see functionality description.)
• When the Gateway is used on a system with battery,
the gateway functionality will follow the power
down mode of the control box, see table
• The MJB – Gateway is not to be used as safety, it is only to be used as a guided
system.
• It is important to test the specified alarms is working in the correct way, before
sending the system to the end user.
• Do not use 2 MJB variants with same device ID on the OpenBus™. This will cause
conflicts and the SDT is not able to identify the different products attached.
• Before the final functional test in the production, it is important that the system
is re-powered. This is to ensure that all items have been detected on the
OpenBus™.
• We recommend the end user to make a regular test procedure in order to
prevent failures and hazardous situations on the system, e.g. defective OOB
sensor, squeezed cables. The MJB is not able to detect defective 3rd. party products.
• LINAK only takes responsibility for LINAK products, not 3rd. party products.
Please pay attention to the “Patient Environment” Clause 3.79 - EN60601-1 3rd
edition: Any volume in which contact can occur between a patient and parts of the
medical equipment or between a patient and other persons touching parts of the
equipment. Justified practice here is 1.5 m. This volume must be subject to the Risk
Analysis.
It is important to inform the customer about this.
• There can be a risk of conflict with other OpenBus™ accessories, such as HB, ACP,
etc. It is therefore recommended to make a system/bit overview.
