In some cases when using temperature mode of operation, it is preferred to disable
energy count below a certain temperature to minimize the influence on the total
energy caused by variance in the work piece start temperature. This function has to
be configured by EFD personnel.
5.2.8
Event output menu (menu 30)
In this menu a specific event can be configured to trigger an output during a
sequence program run. Each of the eight sequence programs can be configured
separately. Two types of events can trigger the output: ‘Temperature reached’ or
‘Segment output’. They are mutually exclusive for each program number. The menu
is dynamic so that if no event is selected for the current program number only the
three first lines in the menu are visible.
F0
Program no
<0-7>
F1
Temperature reached
<ACTIVE/OFF>
F2
Segment output
<ACTIVE/OFF>
‘Temperature reached’ can only be used in equipment fitted with temperature
sensing equipment and when running a sequence in temperature mode of operation.
When Temperature reached is activated the following lines appear:
Temp. reached 1 level (C)
< 0-250 >
Temp. reached 2 level (C)
< 0-250 >
100% corresponds to: (C)
< 250 >
The two Temp. reached levels can be set by the operator to a temperature between
0 and the temperature sensors maximum value (in this case 250 °C). When the
temperature at the sensor is above the set ‘Temp reached level,’ the corresponding
Event output (1 or 2) is high; otherwise it is low. The Event outputs are available only
when using a fieldbus as external interface.
When Segment output is activated, the following lines appear:
F3
Segment no
<0-9>
F4
Event output 1
<LOW/HIGH>
F5
Event output 2
<LOW/HIGH >
The ‘Segment output’ function makes it possible to specify the Event outputs levels
(Low or High) for each segment in a sequence program. The Event outputs are
available only when using a fieldbus as external interface.
Typical use of the event outputs is to synchronize an outside operation with a
heating event.
