6.6.5 Advanced program settings
1. In the "Emi" and "K" boxes you
must enter the pyrometer emis-
sivity and an emissivity factor K
for a quotient pyrometer for the
selected program. The values
entered here have priority for
the measurement pyrometer,
i.e. the value preset in the py-
rometer is overwritten each
time the program runs and also
retained afterwards!
2. If an alarm pyrometer is con-
nected to the PI 6000, it is acti-
vated here. The temperature
range for the pyrometer must
be entered manually, also the
related analogue output and, if
necessary, an appropriate
measuring time must be se-
lected.
The temperature at which the alarm is to be triggered must be set separately for each segment in the
"Alarm" column in the table. The actual temperature measured by the alarm pyrometer can be read using
the program monitor.
3. The entry of a pre-run time will delay program execution after the start; the controller will remain switched
off for this time. The "program start" switched contact (see 5.3.5 Switched outputs) is closed for the en-
tire time the program is executed including any pre-run and follow-up time (e.g. for externally controlled
preparation such as purging with inert gas).
4. The entry of a follow-up time extends the end of the program after it has been completed, the controller is
then switched off and it is not possible to start the program again.
5. An entry in "Length of ready pulse" (program completed) closes the "ready" relay contact (see 5.3.5
Switched outputs) for the time defined after the control program has been completed and any follow-up
time has elapsed.
6. Select the controller current output and interface transmission speed.
7. Temperatures are displayed in the programming environment, on the PI 6000 and on the pyrometer in °C
or °F.
8. Minimum generator level, if it cannot be controlled continuously down to 0%. If the temperature drops
below the value entered, the controller switches from continuous control to on-off control, the minimum on
and off time for the generator is to be entered in the "min t on/s" and "min t off/s" boxes in this case.
9. All found values and settings can be saved in a file and re-loaded. "PI 6000 File" saves all PI 6000
settings in a file, using "PI 6000  File" you can read data saved back into the PI 6000.
7 Placing in operation / controls / display on the unit
Once programming is complete, the PI 6000 can be disconnected from the PC or the PLC and used as a
stand-alone unit, all control programs saved can be opened, started, stopped or interrupted in the same way
as using the program monitor in the software. An LED bar display of the controller output aids visual monitor-
ing of the controller activity. If a PC with the InfraWin software remains connected, the pyrometers desired
and measured graphs can of course be followed while the program is running.
If an alarm pyrometer is connected to the PI 6000 and an alarm has been triggered by the temperature
exceeding the set temperature, this alarm can be disabled using a button, the control program must then be
re-started.
If the measurement pyrometer has a targeting light or a laser targeting light for easy alignment to the object
measured, this feature can be switched on and off directly on the PI 6000.
