Liquid Crystal Display
The P470 control has a LCD that displays the sensed
pressure during normal operation. See Figure 3.
The LCD also displays whether the control is operating
with the primary or secondary setpoints (
S1
or
S2
is
displayed in upper right corner), and indicates if the
control is operating as an Open-high (
) or Open-low
(
) control. (See Figure 3.) The LCD also indicates if
the control is in Anti-Short Cycle Delay. See
Anti-Short
Cycle Delay
in the
P470 Pressure Control Settings
section.
When adjusting the control, the LCD displays the
adjustable setpoints and their values. See Table 2 and
the
Adjustment
section for information on display
codes and changing the settings. After 30 seconds of
inactivity at the touchpad, the control and display
return to normal operation. See Figure 3.
P470 Pressure Control Settings
The P470 control allows the user to establish a variety
of control settings by positioning jumpers inside the
control and using the three-button touchpad to change
setpoint values. For instructions on
Positioning the
Jumpers
, and
Changing the Setpoint Values and
Anti-short Cycle Delay Time-Interval,
see the
Adjustments
section.
PSI
Indicates if the control is operating with either
the Primary ( ) or Secondary ( ) setpoints.
(D only the indicator for the
active setpoints in use is visible in black.
)
S1 S2
uring normal operation
is shown
here in gray to illustrate its position on the LCD.
S2
Indicates pressure (in psi)
sensed at the transducer.
Indicates if the control is operating as an
open-low or open-high pressure control.
(During normal operation only one of the two icons
is visible in black. The open-high icon is shown
here in gray to illustrate its position on the LCD.)

Cut-In
establishes the pressure value (in psi) at which
the output relay is energized, which closes the N.O.
contacts, opens the N.C. contacts, and the LED is on.
Cutout
establishes the pressure value (in psi) at which
the output relay is de-energized, returning the contacts
to their normal positions, and the LED is off.
