Direct/reverse action For rising signal, set for increasing mA out. 5 5 (direct)
(For PI control only) For rising signal, set for decreasing mA out. 6 6 (reverse)
32 *BURN Burn function mA 1 No burnout 0 0.0 No Burn.
mA 1 Burnout downscale 1
mA 1 Burnout upscale 2
mA 2 No burnout 0 No Burn.
mA 2 Burnout downscale 1

33 *RG.mA1(2) PI range Proportional range for mA control signal 10 %
(use >, ^, ENT keys to adjust value)
34 *tI.mA1(2) Integral time 100 sec.
(for PI control)
35 *TABL1 Output table for mA1
*0% Linearization table for mA1 in 5% steps.
*5% The measured value is set in the main
*10% display using the >, ^, ENT keys, for
... each of the 5% interval steps.
... Where a value is not known, that value may
*90% be skipped, and a linear interpolation will
*100% take place.
36 *TABL2 Output table for mA2 Similar to code 35
37 *DAMP Damping time Damping on mA output 0-120 sec. 0. sec.
38-39 Not used
EXAMPLES:
A = bi-lineair
B = hyperbolic (2 decades)
C = logarithmic (2 decades)
D = linear
bi-lin = bi-lineair over 2 decades
log 2 = logarithmic over 2 decades
log 3 = logarithmic over 3 decades
hyp 2 = hyperbolic over 2 decades
hyp 3 = hyperbolic over 3 decades
NOTE: Multiply the values from the table with appropriate
factors to get the end-scale value you want.
