QUICK GUIDE TO LIMITER ADJUSTMENT (FIG. G / DETAIL 2)
The MISIA load limiter is pre-calibrated with two levels:
Threshold 1 = 110% (rated load +10%)
Threshold 2 = 125% (rated load +25%)
During the hoist installation phase, precision calibration may be necessary before testing.
Apply the sample weight (rated load) and proceed as follows:
1) List the load and check the intervention levels are correct.
2) If the intervention level is not exact:
2a) turn the trimmer (1 or 2 according to the thresholds) in an anti-clockwise direction if the limiter does not activate
2b) turn the trimmer (1 or 2 according to the thresholds) in a clockwise direction if the limiter activates before one of the two thresholds is reached.
3) In both cases, ignore the green led (green led 1 or green led 2 according to the thresholds) which flash to indicate the modification in progress.
4) Continue to turn in the pre-selected direction until the red led switches off (red led 1 or red led 2 according to the thresholds) and wait for the
green led (green led 1 or green led 2 according to the thresholds) stops flashing.
5) With the red led off, press the “set” key for approximately 5” (set 1 or set 2 according to the thresholds) and wait for the green led (green led
1 or green led 2 according to the thresholds) to stop flashing.
6) Let the load off and start from point 1) to test the new settings.
