R.4 Simultaneous SEtUP
Both PCPs should be calibrated at the same time on a step by step basis.
Follow the procedure indicated in Section 6.3. With the exception of the
Position Low (PL), Position High (PH), Control Point (CP), Signal Low (SL)
and Signal High (SH), all values in the SEtUP Mode will be identical. The
values for these parameters will be different because of separate feedback
readings and variations in internal resistors.
Position Low (PL), Position High (PH) and Control Point (CP) require repo-
sitioning of the actuator to set their values. Use only one module to move
the actuator. When the correct position is reached, lock this position into
both PCPs.
In the case of dual control signal, insure that both PCPs are receiving the
correct high or low value setting. Variations of only .2 or .3 mA may cause
control instability.
Control point is an advanced
control option and may not
be available on a particular
unit.
