8 - DIAGNOSTICS
8.1 - Control diagnostics
The control system has many fault tracing aid functions, protecting
the unit against risks that could result in the failure of the unit.
The local interface gives quick access to monitor all unit operating
conditions. If an operating fault is detected, the alarm is triggered.
In the event of an alarm:
■ The bell on the SmartVu user interface starts ringing.
The ringing yellow bell icon indicates that there is
an alarm, but the unit is still running.
The ringing red bell icon indicates that the unit is
shut down due to a detected fault.
■ The corresponding alarm output(s) is/are activated.
■ Error code is displayed.
■ Message is sent over the network.
SmartVu control distinguishes between two types of
alarms:
■ General alarms are used to indicate pumps failure, transducers
faults, network connection problems, etc.
■ Major alarms are used to indicate process failure.
IMPORTANT: All information regarding alarms (current and
past alarms) can be found in the Alarms menu (see also
section 5.9).
8.2 - Displaying current alarms
The Current alarms menu may display up to 10 current alarms.
To access the list of currently active alarms
1. Press the Alarms menu button in the upper-right part of the
screen.
2. Select Current Alarms (CUR_ALM).
3. The list of active alarms will be displayed.
8.3 - E-mail notifications
The control provides the option to define one or two recipients
who receive e-mail notifications each time the new alarm occurs
or all existing alarms have been reset.
To define e-mail recipients
1. Press the Main menu button and navigate to the Configuration
menu.
2. Go to the Network menu.
2. Select Email Configuration (EMAILCFG).
3. Define user e-mail(s).
8.4 - Resetting alarms
The alarm can be reset either automatically by the control or
manually through the touch panel display or the web interface.
■ The Reset alarms menu displays up to 5 alarm codes which
are currently active on the unit.
■ Alarms can be reset without stopping the machine.
■ Only logged-in users can reset the alarms on the unit.
To reset the alarm manually
1. Press the Alarms menu button in the upper-right part of the
screen.
2. Select Reset Alarms (ALARMRST).
3. Set “Alarm Reset” to “Yes” and press the Force button.
In the event of a power supply interrupt, the unit restarts
automatically without the need for an external command. However,
any faults active when the supply is interrupted are saved and
may in certain cases prevent a circuit or a unit from restarting.
Once the cause of the alarm has been identified and corrected,
it will be displayed in the alarm history.
It is also possible to reset the alarms by CCN, with System Pilot
for example.
IMPORTANT: Not all alarms can be reset by the user. Some
alarms are reset automatically when operating conditions
return to normal.

menu which is divided into 50 recent alarms and 50 recent major
