Calibrate Zero on Proportional Controllers
1. Depending on the controller type the supply
pressure will be 20 or 35 psi. Attach a suitable
pressure gauge to the output pressure.
2. Connect the pressure source to the pressure
block and set the proportional bandwidth to 15%
(1.5).
3. Zero the pressure setting dial.
4. Raise or lower the nozzle (Key 34, Figure 6)
to get the desired setting of zero as per chart
below. Nylon insert will hold the nozzle in place.
5. Allow maximum pressure to the measuring ele-
ment. Set the pressure dial to maximum. Output
pressure should comply with the zero setting
column in the following table, if not go to
Note 1.

Calibrate Zero on Proportional- Reset
Controllers
1. Depending on the controller type the supply
pressure will be 20 or 35 psi. Attach a suitable
pressure gauge to the output pressure.
2. Connect the pressure source to pressure block
and set the proportional bandwidth to zero.
3. Set the reset dial to .005 minutes per repeat.
4. Zero the pressure setting dial.
5. Raise or lower the nozzle (Key 34, Figure 6) to
get the desired setting of zero as per
chart below. Nylon insert will hold the nozzle in
place.
6. Allowing maximum pressure to the measuring
element. Set the pressure dial to maximum. Out-
put pressure should comply with the zero setting
column in the following table, if not go to Note 1.
Note 1 - These steps are to be used if the zero setting
pressure or output range is not obtained when maximum
pressure is applied to the measuring element.
1. Move the calibration adjuster (Key 30, Figure 6)
to the right or the left.
2. Repeat the nozzle adjustment and Step 5 for
proportional controller, or Step 6 for proportional-
reset controller.
3. To release the calibration adjuster, loosen two
screws, above and below the beam, to the left of
the nozzle.

Changing of Controller Output
Controllers having an output range of 3-15 psi, can be
converted to having an output range of 6-30 psi. This
can be done by changing the two color coded control
bellows. The green bellows is for 3-15 range, and yellow
bellows for 6-30 psi range.
When the pressure range is changed, it is necessary to
change the pressure gauges. This can be completed
by unscrewing the old pressure gauges from their boss
and screwing in the new gauges.
