2.2 Operation Menu
Operation Menu Diagram
Operation menu allows the user to start and stop the analyzer. Menus related to system operation are also
accessed using this menu.
2.2.1 Start Stop
The user can Start or Stop the BioTector using the Start Stop menu.
1. Remote Standby. Remote Standby is an optional function, which is activated from Input 2 (by default) on
the Power and Input/Output Board (e.g. from a flow switch). A “REMOTE STANDBY” message is displayed
on the top left corner of the main Analysis Data screen to indicate that the BioTector is in remote standby
state. When remote standby signal is activated, the BioTector stops analyzing. All menu access and
operational functions remain as for BioTector normal running state. The BioTector runs one standby
reaction every 24 hours, at the time programmed for the Pressure/Flow Test (at 08:15 AM by default).
Sample is not taken during the remote standby reaction (only acid and base reagents are used). This
reaction is tagged as “RS” (Remote Standby) in the system reaction archive. The 4-20mA signal or other
output devices are not updated. When remote standby signal is deactivated, the BioTector starts analyzing.
When remote standby signal is activated, the “Finish & Stop” or “Emergency Stop” must be selected before
using such functions as Install New Reagents, Zero and Span Calibrations, Process Tests etc. If the
BioTector is stopped using the “Finish & Stop” or “Emergency Stop” functions or automatically by a system
fault, it will not be possible to start the BioTector by the removal of the remote standby signal. The “Start”
function must be used to re-start the BioTector. When BioTector is started while the remote standby signal
is activated, BioTector goes into remote standby state. The manual grab sample analysis can be carried out
normally using the Manual Program menu when the BioTector is in remote standby state.
Maintenance should only be carried out when “SYSTEM STOPPED” message
is displayed on the top left corner of the main Analysis Data screen or when
the system is powered down. When “REMOTE STANDBY” or “SYSTEM
RUNNING” message is displayed on the screen, stop the BioTector using the
“Finish & Stop” or “Emergency Stop” function.
