1. Use spring retainer spacer 1J8038 46172; for additional information, see table 7.
2. Use spring retainer spacer 1J2233 46172; for additional information, see table 7.
3. Use spring retainer spacer 1J8039 46172; for additional information, see table 7.
4. Use with high pressure bellows and spring retainer spacer 1J8039 46172; for additional
information, see table 7.
5. Use with high pressure bellows.
6. Use with high pressure bellows and spring retainer spacer 1J2233 46172; for additional
information, see table 7.
7. Use spring retainer spacer 1P3957 X012; for additional information, see table 7.
8. For use with Type 480-12 or 480-15 size 20 actuators.
9. For Type 3570P signal range codes, contact your Fisher sales office or sales
representative.
3. Provide a means for varying the input signal pres-
sure from zero to 1 or 2 psig (0.07 or 0.14 bar) above
the higher value of the input signal range (see table 1).
Provide an accurate means of measuring the input
signal pressure. Check the accuracy of the positioner
instrument pressure gauge (see figure 2). The gauge
accuracy is±0.6 psig (±0.04 bar) on a 0 to 30 psig (0 to
2 bar) gauge, and ±1.2 psig (±0.08 bar) on a 0 to
60 psig (0 to 2 bar) gauge. This accuracy is measured
at the mid-point of the full range of the scale.
4. Set the input signal pressure at the mid-point of its
range [9 psig (0.6 bar) in this example]. Observe the
valve travel indicator scale attached to the yoke. The
indicator disk should be somewhere between the open
and closed positions.
5. Loosen the locknut directly below the bias spring
seat (see figure 3) and adjust the bias spring up or
down until the valve travel indicator disk shows that
the valve plug is somewhere between the open and
closed positions. Upward movement of the bias spring
adjustment causes downward travel of the valve stem.
6. For positioners with two relays (Type 3570, 3570C,
3570P, 3570PC, and 3571 positioners), observe the
relay output pressures. If the cylinder gauges are
present as shown in figure 2, read the cylinder top and
cylinder bottom gauges or use clip-on test pressure
gauges. The two relay output pressures should be
approximately equal [within 5 psig (0.3 bar)] and
should be approximately 75 percent of the supply
pressure. For example, if the supply pressure is 100
psig (7 bar), the two relay output pressures should be
within 5 psig (0.3 bar) of each other, and should be
approximately 75 psig (5.2 bar).
CAUTION
The relays in the Type 3570C and 3570PC
positioners use a locknut (key 29P, figure
11) on the nozzle (key 29Q). If the nozzle
is rotated when the locknut is tight, dam-
age to the relay diaphragm might result.
Always use a wrench on the nozzle to
prevent it from turning while loosening or
tightening the locknut.
