Primary Sensor or Hall-Effect Sensor
(two pins on the right
)
Monitoring mode [
.!X!
] = 33 has following exceptions:
CURRENT
- current in [%] from 0000 (0 %) to 0099 (99%);
7!U!
- Low current limit window in [kA] from 00.00 (0 kA) to 99.99 (99.99 kA);
3!O!
- High current limit window in [kA] from 00.00 (0 kA) to 99.99 (99.99 kA).
In this mode also, RMS in [kA] will be shown on DATA display after end of the sequence,
which may be useful for setting Hi/Low limit window.
8.4.3 CHOOSING A RANGE
The desired range should be as close as possible to the maximum operating range of the
welding machine. If the programmed range is far below or far above operating range, after
any weld the RMS current may be far above or far below desired RMS values, or with
[
;!:!
] = 12 the Control will display Error HI or LO. In such cases, the range has to be
changed by programming lower or higher [
X!,!
], otherwise the Transformer TAP has to be
moved up or down, if that is possible.
If the operating range of the welding machine is unknown, running the setup procedure is
recommended. After running the setup for [
.!X!
] = 30, and [
X!,!
] is any value except 00.99,
approximately the maximum RMS value will be stored in [
X!,!
]. Once that value has been
determined for the TAP setting necessary for a good weld, go to the table on previous page
and determine the range parameter
[
X!,!
] closest to the value determined by the setup and
use that value when reprogramming [
X!,!
] in the manual range mode with [
.!X!
] = 32 or 33.
8.5 SENSOR SELECTION JUMPER SETTINGS
Proper jumper settings for different type of the sensors is shown on Figure 8.5.1 (for Primary
Sensor or Hall-Effect Sensor) and Figure 8.5.2 (for Secondary Rogowski Coil).
