7.4.2  Direct set point modification

This function allows to modify rapidly the set point value 
selected by [79] SPAt (selection of the active Set point) or 
to the set point of the segment group (of the programmer) 
currently in progress.
The instrument is showing the “Standard display”.

1. 

Push 

 button. 

The display will show alternately the acronym of the 
selected set point (e.g. SP2) and its value;

Note: 

When the programmer is running, the instrument 
shows the set point of the group currently in use 
(e.g. If the instrument is performing the soak 3 the 
instrument shows [104] Pr.S3).

2. 

By 

 and 

 buttons, assign to this parameter the 

desired value;

3. 

Do not push any button for more than 5 second or push 
the 

 button. 

In both cases the instrument stores the new value and 
returns to the “Standard display”.

Note: 

If the selected set point has not been promoted to the 
Operator level, the instrument allows you to see the 
value but not to modify it.

7.4.3  Additional information

This instrument is able to show you some additional 
information that can help you in managing your system.
The additional information are related to how the instrument 
is programmed, hence in many cases, only part of these 
information are available.

1. 

When the instrument is showing the “Standard display” 
push 

 button.

The display shows 

H

 or 

c

 followed by a number.  This 

value is the current output power applied to the process. 

H

 indicates that the action is a Heating action while  

c

 says that the action in progress is a Cooling action.

2. 

Push 

 button again.  When the programmer is running 

the display shows the segment currently performed and 
the Event status:  

r1.00

 where the first character can be 

r

 for a ramp 

or 

S

 for a soak, the next digit shows the number of the 

segment (e.g.: 

S3

 means Soak number 3) and the two 

Less Significant Digits (LSD) indicate the status of the two 
events (the LSD is the Event 2);

3. 

Push 

 button again.  When the programmer is running 

the display shows the theoretical remaining time to the 
end of the program preceded by a 

P

 letter: 

P84.3

.

4. 

Push 

 button again.  When the wattmeter function is 

running the display shows 

U

 followed by the measured 

energy.

Note: 

The energy calculation will be in accordance with 
the [123] Co.tY parameter setting.

5. 

Push 

 button again.  When the “Worked time count” 

is running the displayl shows 

d

 for days or 

h

 for hours 

followed by the measured time.

6. 

Push 

 button again.  The instrument returns to the 

“Standard display”.

Note: 

The additional information visualization is subject to a 
time out.  If no buttons are pressed for more than 10 
seconds the instrument automatically returns to the 
“Standard display”.

7.4.4  The programmer function

In “Chapter 5” we have described all parameters related with 
the programmer and their action during program execution.
In this paragraph we give you some additional information 
and some application examples.

Note: 

The decimal point of the LSD of the display is used 
to show the programmer status independently from 
the displayed value selected by [114] diSP (Display 
management).

Decimal point 
of the LSD

.

The relation between the programmer status and the 
LED  are the following:

• 

Program in RUN - The LED is ON;

• 

Program in Hold - The LED flashes fast;

• 

Program in Wait - The LED flashes slow;

• 

Program in end or reset - The LED is OFF.

Application example 1: Spray Paint Drying Booth.

When the operator is in the booth painting the car, the 
internal temperature must be 20°C and the air used for booth 
ventilation comes from outside.

Shutter

During the passivation and drying phases, the operator is out 
of the booth and the system closes the air shutter to recycle 
the internal air in order to reduce the power consumption.

Shutter

When the drying time is finished, before the operator is 
allowed to enter the boot, you must be sure that:

1. 

The air in the booth has been refreshed;

2. 

The temperature is lower than a limit.  So that you need a 
profile like the one below:

Out 3 = P.run (program running);
Pr.E1and Pr.E2 = 10.10 (event 1 goes ON during ramp 1, 
soak 1, ramp 2 and soak 2).

When the program is running the door is locked.
