This table shows the effect of the output frequency of changing proportional gain
and bias with the following settings:
ctrI SPAN = 20, A1.dc = 1.0, A1.IG = 0.000
A1.SP A1.PG A1.bS Effect on relay operation
70 1.000 0.0 Reading of 50 or below - relay permanently on.
Reading of 50 to 70 - relay pulses with off time increasing as
value approaches 70.
Reading 70 or above - relay permanently off.
70 1.000 100.0 Reading of 70 or below - relay permanently on.
Reading of 70 to 90 - relay pulses with off time increasing as
value approaches 90.
Reading 90 or above - relay permanently off.
70 1.000 50.0 Reading of 60 or below - relay permanently on.
Reading of 60 to 70 - relay pulses with off time increasing as
value approaches 70.
Reading 70 - relay pulses at 50% on and 50% off.

7.5 PI relay integral gain
Display: Ax.IG
Range: -32.767 to 32.767
Default Value: 0.000
Note: the range value may be restricted if the number of display digits does not allow viewing of
the full range.
The Integral action will attempt to correct for any offset which the proportional control action is
