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. 

 

8.5  - Alarm history 

Information regarding resolved alarms is stored in the Alarm history 
menu which is divided into 50 recent alarms and 50 recent major 
alarms. 

To access the alarm history 

1.  Press the 

Alarms menu 

button in the upper-right part of the 

screen. 

2. 

Select 

Alarm  Historic 

(ALMHIST1)  or 

Major Alarm  Historic 

(ALMHIST2). 

3.  The history of alarms will be displayed.
