Product Overview

6 P—
P470 Electronic Pressure Control with Display Product/Technical Bulletin
A
djustments
This section provides instructions for setting up and
adjusting the P470 control using the internal jumpers
and front panel touchpad.
Positioning the Jumpers
The
P5
jumper-pin terminal has a single pair of jumper
pins and is used to lock or unlock the touchpad. The
P6
jumper-pin terminal has two pairs of jumper pins
and is used to establish the control’s operating
pressure range.
To position a jumper in the Installed position, place the
jumper on both pins. To position a jumper in the
Removed position, place the jumper on only one pin.
(Save the jumper in case it is required in the future.)
See Figure 8.

Figure 8: Positioning the Jumpers
Set the jumpers as follows, using Figures 8 and 9 as
guides.
1. Disconnect all power sources to the P470 control.
2. Remove the control’s cover by loosening the
four captive cover screws.
3. Position the jumpers to set the desired operating
pressure range and lock or unlock the touchpad.
4. Replace the cover, and restore power to the
control.
IMPORTANT: The P470 control’s three field-
selectable operating pressure
ranges require specific P399
transducer models for the control
to operate properly.
Do not use
a transducer model that is not
specified for the P470 control’s
field-selected operating
pressure range.
See Table 1.
