The following parameters can be set:
• Filter settings
See Table 3-4.
• High Tension (N, kN, kg, lbs, N/m, kN/m, kg/m, pli), (factory default = 2000 N)
• High Output, (factory default = 20 mA)
• Low Tension (N, kN, kg, lbs, N/m, kN/m, kg/m, pli), (factory default = 0 N)
• Low Output, (factory default = 4 mA)
• High Limit, (factory default = 21 mA)
• Low Limit, (factory default = 0 mA)
Figure 3-15. Parameter Definitions
Filtering may be used if the current output signal is too fast or to compensate roll imbalance.
The filters are of type linear phase, maximum flat, 20 dB/decade.
