UPT-640 (as of SW 100)
menu or by means of the "AUTOCAL" signal, termi-
nals 20+25). The progress of the calibration process
is indicated by a counter on the display (approx.
10…15s). A voltage of app. 0VDC appears at the
same time at the actual value output (terminals
20+24). If an ATR-x is connected, it indicates
0…3°C.
When the zero point has been calibrated, the dis-
play is reset to the home position and 20°C is indi-
cated as the actual value. A voltage of 0.66VDC (for
the 300°C range) or 0.4VDC (for the 400°C range,
equivalent to 20°C, appears at the actual value
output. If an ATR-x is connected, it must be set to "Z"
(20°C).
If the zero has not been calibrated successfully, an
erro message indicates error codes 104…106, 211.
In this case the controller configuration is incorrect
(
Kap. 8.3 „Controller configuration“ auf Seite 18
and ROPEX Application Report). Repeat the zero
point calibration after the controller has been confi-
gured correctly.
9. When the zero point has been calibrated suc-
cessfully, the main menu appears on the display
again. Then specify a defined temperature (heatse-
aling temperature) with step 1 in the Settings menu
(or apply a 0…10VDC voltage to the analog input,
terminals 20+23) and activate the "START" signal
(HEAT). Alternatively, a heatsealing process can be
started by pressing the "HAND" key (display in
home position). The indication of the ACTUAL tem-
perature on the display (digital value and dynamic
bar) permits the heating and control process to be
monitored.
The controller is functioning correctly if the tempera-
ture indicated on the display has a continuous
curve, in other words it must not jump abruptly, fluc-
tuate or deviate temporarily in the wrong direction.
This kind of behavior would indicate that the U
R
measuring wire has been laid incorrectly.
If an error code is displayed, please proceed as
described in section 9.27 "Fault areas and causes"
on page 50.
10.Optimizing the heating up and temperature control
function by adjusting the correction factor Co in
menu step 110 (
section 9.11 "Correction factor
Co" on page 34). With this procedure the produc-
tion-related resistance tolerances of the heating ele-
ment will be compensated.
If the heatsealing temperature is selected via
the analog input at terminals 20+23, the spe-
cified voltage value must be checked with a volt-
meter before the heatsealing process begins, in
order to prevent incorrect settings or excessively
high heatsealing temperatures.
The controller is now
ready
