To set any of the numerical parameters, use the NAVIGATION keys (Figure 1) to place the
cursor over the number. Key in the desired value, and then press ENTER.
To change the ON/OFF parameters, place the cursor over the parameter, and press ENTER to
toggle between ON and OFF.
WARNING RESPONSE TIME
Warning response time (range 2 – 99 seconds)
If the blade deviation exceeds the preset warning limit for longer than warning
response time, then the beacon light mounted on the top of the head will start
flashing.
MAX LIMIT RESPONSE TIME
Maximum limit response time – (range 2 – 99 seconds)
If the blade deviation exceeds the preset shutdown limit for longer than
shutdown response time, then the machine will execute shutdown sequence.
SENSOR
(range –2000 – +2000)
The number displayed here represents the position of the blade within the
measuring range of the proximity transducer. At 0, the blade is exactly
centered within the sensing range. The display assists adjustment with the
prompts ‘SETTING, or ‘SET’. The prompt ‘SET’ appears when the adjustment
is within the acceptable range of – 100 +100.
[See sensor adjustment procedure section]
BLADE DEVIATION MONITOR ON/OFF
This parameter will activate or deactivate response of the blade deviation
monitoring system.
DISPLAY REFRESH RATE
(range 0.1 sec – 10 sec)
The refresh time is time between bar graph updates. If it is set to low value
then the display will flicker do to vibration of the blade, weld passing by the
sensor or other irregularities in the blade.
Figure 4 Parameter description chart.
Relationship between Blade Deflection Display and Actual Cut Deviation
The digital display indicates the blade lateral deflection at the point where it passes the blade
deflection sensor, which is 1” past the idler side guide arm. The display range of0 +/-100 is
proportional to the amount of blade deviation. This depends on the type of material, shape of
the work-piece and amount of blade tension. The maximum deviation of the cut surface will
occur at or near the center of the cut, and will be several times larger than that measured at the
sensor.
The actual amount is difficult to predict, experience with different work-pieces will
provide the best guide.
