 Hbd group - Heater break down alarm 

General note about HBD alarm

The HBD alarm operate as follows:  The instrument perform 
the measurement of the current running in a load.  This 
measurement is made by a current transformer (CT) with a 
0.05 A A.C. full scale output. 
The load can be: independent (not managed by an output 
of the KM2) or managed by an output of the KM2.  In the 
first condition (independent), the instrument will perform the 
current measurement continuously and it will compare the 
measured value with 3 thresholds: a minimum alarm (Ct.LE), 
a maximum alarm (Ct.Ld) and an over-current alarm(Ct.oc). 
In the second condition (load manage by an output of the 
KM2) the instrument is able to identify the load condition (ON 
or OFF) and manages the thresholds according to the status.
When the out (used to turn ON and OFF the load) is OFF, 
the measured value is used to verify that the leakage current 
is lower than a preset value (Ct.LE = leakage current) in 
order to be sure that the actuator disconnect the output.  
When the out (used to turn ON and OFF the load) is ON, 
the measured value is used to verify that the load current is 
higher than a preset value (Ct.Ld = load current) but also  it 
must be lower of the over-current threshold (Ct.oc) in order 
to verify that the load operate correctly.

• 

OFF when PV > (SP + hysteresis);

• 

ON when PV < (SP - hysteresis).

[58] Auto - Auto tune selection

Ascon Tecnologic has developed three auto-tune algorithms:

 

Oscillating auto-tune;

 

Fast auto-tune;

 

EvoTune.

1. 

The 

oscillating

 auto-tune is the usual auto-tune and:

• 

It is more accurate;

• 

Can start even if PV is close to the Set Point;

• 

Can be used even if the Set Point is close to the 
ambient temperature.

2. 

The 

fast type

 is suitable when:

• 

The process is very slow and you want to be opera-
tive in a short time;

• 

When an overshoot is not acceptable;

• 

In multi-loop machinery where the fast method reduces 
the calculation error due to the effect of the other loops.

3. 

The 

EvoTune

 type is suitable when:

• 

You have no information about your process;

• 

You can not be sure about the end user skills;
