Information on the lid opening
The purpose of the analyser lid is to protect the user when the pipetting arm moves.
Opening the lid during use stops any movement of the pipetting arm in order to guarantee the user’s safety
during operation.
All analysers are equipped with sensors to detect the opening or closing of the lid.
To increase the level of security, the latest analysers are now equipped with an electro-magnetic lid locking
system, managed by software.
The locker is located under the lid, at the rear, right side. The lid is continuously locked, even when the
analyser is o
ff . The lid can be opened only after sending the unlock command from the user interface.
Access to the lid’s opening is controlled and authorised only when the analyser is not in cycle mode. In this
case, the unlock lid button is displayed on the main screen.
Certain operations described from this section require the lid to be opened e.g. installation of TRIGGER A and
TRIGGER B, maintenances, etc. Depending on the presence or absence of the locking system, the procedure
for the lid’s opening is di
ff erent.
The lid must always be fully opened and the lid support tool provided with the analyser must always be
installed in order to ensure the user’s safety.
When the lid support tool is fully inserted onto the piston rod, the lid can not accidentally fall down.
Analysers without locking system
The lid can be opened directly. The sensors on the analyser will detect that he lid has been opened and
prevent any movement of the pipetting. The only exception to this is during the adjustment procedure for the
reference position of the sampling needle.
When the lid is opened, the pipetting arm is powered but remains in its last position and any movement is
stopped. An accidental opening during the run cycle interrupts sampling and may result in recycling.
Analysers fitted with locking system
The lid can only be opened if unlocked. Lid unlocking is requested by using a function button on the main
screen, displayed only if the analyser is not in cycle mode. Before final unlocking, the pipetting arm moves to
its home position, located at the left side of the reagent compartment, with the sampling system on its bracket.
The pipetting arm is then turned o
ff and the lid can be opened to perform the required operations. The lid is
locked as soon as closed. The pipetting arm will remain in home position until the next use (run cycle,
priming,..).

From the main screen, click on .
The command for unlocking is sent to the analyser

The message displays:
The sampling arm moves to its home position.

When the lid is unlocked, the message and the unlock button are no longer displayed.
•
The lid can then be opened.
