The alarm output is switched if the "START" signal is
activated while an alarm signal is indicating error codes
104…106, 111…114, 211, 302 or 303 (up to Sep-
tember 2005: error codes 8…12) (
ª
"Error messages" on page 31). The heatsealing band is
no longer heated up.
9.6
Measuring impulse duration
(as of October 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 9.10 "Diagnostic interface/visualization
software (as of October 2005)" on page 30).
9.7
Automatic phase angle
compensation (AUTOCOMP)
(as of October 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. It is executed whenever the
"AUTOCAL" function (
ª
messages" on page 31) 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 "HEAT" LED blinks repeatedly when the "AUTO-
COMP" function is executed and the actual value
output (terminals 17+14) is set to 0…3°C (i.e. app.
0 VDC).
The "AUTOCOMP" function must be
activated in the ROPEX visualization
software (
ª
section 9.10 "Diagnostic interface/
visualization software (as of October 2005)" on
page 30) (default setting: AUTOCOMP off).
