7 Start Up and Shut Down the ‘Abacus 5’
7.1 Start Up and Shut Down Overview
The ‘Abacus 5’ is an advanced instrument with computer and pneumatic subsystems that need to be properly started
up and shut down for continuing reliable performance. Not following proper startup and shutdown procedures may
lead to increased maintenance and unnecessary service calls.
The ‘Abacus 5’ analyzer start up sequence requires four steps:
 Power up the electrical system.
 Start up the internal user interface computer and log in if the multi-user mode is activated.
 Start up the pneumatic system components.
 Perform and accept an initial ‘blank’ measurement.
A normal shut down of the ‘Abacus 5’ analyzer has the reverse steps:
 Clean and empty the pneumatic system components.
 Log off (multi-user mode is activated) and properly shut down the internal user interface computer.
 Power down the electrical subsystem.
The ‘Abacus 5’ analyzer also has a ‘prepare for shipment’ shut down option that performs an extended cleaning and
emptying of the pneumatic components. This option can be used to prepare the ‘Abacus 5’ analyzer for an extended
period of inactivity or for shipping to a new location.
There are also emergency shutdown procedures in case of emergency.
7.2 Starting Up the ‘Abacus 5’ Analyzer
7.2.1 Visual Inspection
Perform a visual inspection of the ‘Abacus 5’ analyzer before starting up. This is particularly important if the ‘Abacus
5’ is operated by multiple operators.
 Check the reagent tubes by gently pulling on them to make sure that connections are not loose.
 Open the front cover and ensure that there is no leakage around the shear valve or the syringe pumps.
 Check for salt stains around the reagent tubing and the reagent containers.
 Check that the power cord is plugged in both into the back panel of the ‘Abacus 5’ analyzer and to the wall
outlet.
 Empty the waste container. After start up reset the waste level in the “Main menu/ Diagnostics/Reagent
status panel”.
7.2.2 Power Up the ‘Abacus 5’ Analyzer
To power up the ‘Abacus 5’ analyzer, perform the following steps:
 Turn on the main power switch (small switch) on the rear panel of the ‘Abacus 5’ analyzer located near the
power connection to the ‘up’ position labeled ‘1’ to power on the electrical system of the ‘Abacus 5’ analyzer.
 If the optional Autosampler is installed, turn the power switch on the right side of the Autosampler to the
‘on’ position labeled ‘1’ to power on the electrical system of the Autosampler.
 Turn on printers or any peripherals that have their own power switches.
