Controller functions
RES-407 Page 29
The controller performs an internal
initialization run lasting approximately
500ms after the "RESET" signal is deactivated. The
next heatsealing process cannot be started until it
has finished.
If a contactor Kb is used to deactivate the
control loop
( ª ª ª ª section 8.3 "Power supply"
on page 14 ), it must be energized again 50ms at the
latest after the "RESET" signal is deactivated. If it is
energized too late, an error message will be output
by the controller.
10.7 Measuring impulse duration
(as of April 2005)
The length of the measuring impulses generated by the
controller can be set with the parameter. It may be
necessary to set a measuring impulse that is longer
than the default 1.7ms for certain applications
(
ª ROPEX Application Report).
This parameter can only be set by means of
the ROPEX visualization software
( ª section 10.11 "Diagnostic interface/
visualization software (as of April 2005)" on
page 31).
10.8 Automatic phase angle
compensation (AUTOCOMP)
(as of April 2005)
It may be necessary to compensate the phase angle
displacement between the U
R
and I
R
measuring
signals for special heatsealing applications ( ª ROPEX
Application Report). The "AUTOCOMP" function is
provided for this purpose. The following settings are
possible:
1.
„OFF" (Factory settings)
The „AUTOCOMP“ function is deactivated.
2. „ON“
The „AUTOCOMP“ function is executed whenever
the "AUTOCAL" function (
ª section 10.4
"Automatic zero calibration (AUTOCAL)" on
page 27) is run twice in quick succession. The
interval between the end of the first "AUTOCAL"
function and the start of the second "AUTOCAL"
must be shorter than 2.0s. The second "AUTOCAL"
function only takes around 2.0s and incorporates
the "AUTOCOMP" function.
If the interval between the two "AUTOCAL"
functions is longer than 2.0s, "AUTOCAL" is
executed normally again the second time.
The "OUTPUT" LED blinks repeatedly when the
"AUTOCOMP" function is executed and the actual
value output (terminals 17+14) is set to 0…3°C (i.e.
app. 0 VDC).
3. „AUTO“
(as of software revision 108)
With this setting the „AUTOCOMP“ function is acti-
vated automatically after the "AUTOCAL" function
has been successfully executed.
