INTRODUCTION
The PD689 is an intrinsically safe and non-incendive loop-powered
rate/totalizer approved for hazardous area locations. The PD684 is a
general-purpose loop-powered rate/totalizer for safe area applications.
The four front panel buttons make the setup and programming an easy
task. Five digits, bargraph, engineering units, scientific notation, rate &
total indication, and trend arrows provide a clear and attractive presentation of the process.
The square root and programmable exponent functions allow for conditioning of signals from non-linear transmitters without adding external
components to the system and the convenience of scaling without a
calibrated signal source make the PD684 & PD689 the ideal choice for
flow rate & total display applications.

INSTALLATION
There is no need to remove the meter from its case to complete the installation, wiring, and setup of the meter.
Unpacking
Remove the meter from box. Inspect the packaging and contents for damage. Report damages, if any, to the carrier.
If any part is missing or the meter malfunctions, please contact
your supplier or the factory for assistance.
Panel Mounting
Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm
x 45 mm). Refer to Mounting Dimensions, page 41 for more details.
Clearance: allow at least 4" (102 mm) behind the panel for wiring.
Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Minimum steel/stainless steel panel thickness to maintain watertight
rating: 0.06" (1.5 mm).
Note: A steel or stainless steel panel rather than plastic is
recommended in cases where a watertight or dust-tight seal is
required between the meter and the panel.
Remove the two mounting brackets provided with the meter (back-off
the two screws so that there is ¼" (6.4 mm) or less through the
bracket. Slide the bracket toward the front of the case and remove).
Insert meter into the panel cutout.
Install mounting brackets and tighten the screws against the panel.
To achieve a proper seal, tighten the mounting bracket screws
evenly until meter is snug to the panel along its short side. DO NOT
OVER TIGHTEN, as the rear of the panel may be damaged.

Noise Filter (fltEr)
Most applications do not require changing this parameter. It is intended
to help attain a steady display with an unsteady (noisy) input signal.
The field selectable noise filter averages any minor or quick changes in
the input signal and displays the reading with greater stability.
Increasing the filter value will help stabilize the display, however this will
reduce the display response to changes on the input signal.
The filter level may be set anywhere from 1 to 199.
Noise Filter Bypass (bypAs)
The meter can be programmed to filter small input changes, but allow
larger input changes to be displayed immediately, by setting the bypass
value accordingly.
If the input signal goes beyond the bypass value, it will be displayed
immediately with no averaging done on it.
The noise filter bypass value may be set anywhere from 0.2 to 99.9. It
corresponds to percentage of full scale.
Increasing the bypass value may slow down the display response to
changes on the input signal.
Contrast (contr)
LCD contrast is adjustable through the front panel buttons. Select contr
and increase level using Up Arrow/Max button. Settings 1 through 9 will
be displayed on the screen as 11111 to 99999. Settings 1 through 4 are
usually best when viewing from below the angle perpendicular to the
display. Settings 5 through 9 are usually best when viewing straight on
(meter is at eye level) or when viewing from above.

Alarm & Pulse Output (out)
The PD684 & PD689 are equipped with an NPN open collector output
that may be set up for high or low rate alarm trip point, total alarm trip
point, or pulse output based on K-factor. The pulse output frequency
may be programmed for 2, 4, 8, 16, 32, 64, or 128 Hz.
The output may be disabled by selecting -off-. The alarm status will
show on the display even if the output is not wired.

Alarm Output (alrm)
Rate high alarm trip point: program set point above reset point.
Rate low alarm trip point: program set point below reset point.
Rate alarm deadband is determined by the difference between set
and reset points. Minimum deadband is one display count. If set
and reset points are programmed the same, output will reset one
count below set point.
Total alarm trip point: program total set point. Alarm reset is trig-
gered by total reset (There is no reset parameter entered for total).
If automatic total reset is enabled, this setting will be the trigger
point for the timer. It is not necessary to have the output wired for
automatic reset function to work.
To acknowledge rate or total alarm, press and hold Enter/Ack button for
two seconds.
Pulse Output K-Factor (Pulse)
The pulse output K-factor corresponds to the total units (e.g. gallons)
needed to generate one pulse. For example, if the K-factor value is set
to 10, one pulse is generated for every 10 counts incremented on the
display. Likewise, if the K-factor value is set to 100, one pulse is generated for every 100 counts incremented on the display.
If the pulse output exceeds the programmed output frequency, pulses
are accumulated as pending and are not lost. Pulses will continue to
output until the buffer is emptied or the total is reset from the front panel.

Features
Press Enter to Accept Setting
prog.e cutof
Linear (lnear)
Meters are set up at the factory for linear function. The linear function
provides a display that is linear with respect to the input signal.
Square Root (Squar)
The square root function is used to linearize the signal from a differential
pressure transmitter and display flow rate in engineering units.
Programmable Exponent (Prog.E)
The programmable exponent function is used to linearize the level signal in applications using weirs and flumes and display flow rate in engineering units. Upon selecting programmable exponent (Prog.E), the meter prompts entry of a 5-digit value between 0.5000 and 3.0000 as the
exponent.
Low-Flow Cutoff (CutoF)
The low-flow cutoff feature allows the meter to be programmed so that
the often-unsteady output from a differential pressure transmitter, at low
flow rates, always displays zero on the meter. The default cutoff is zero
to prevent negative readings, but this may be overridden to allow them.
The cutoff value may be programmed from -99999 to 99999. Below the
cutoff value, the meter will display zero. Selecting either square root or
programmable exponent will set the cutoff value to 0. Program the cutoff
value to -99999 to disable.

Internal Calibration (ICal)
There is no need to recalibrate the meter for
milliamps when first received from the factory.
The meter is factory calibrated for milliamps
prior to shipment. The calibration equipment is
certified to NIST standards.
The internal calibration allows the user to scale the meter without applying a signal. The use of a calibrated signal source is necessary to perform the internal calibration of the meter. Check calibration of the meter
at least every 12 months.
Notes:
The signal source must have a full-scale accuracy
of 0.01% or better between 4 and 20 mA in order
to maintain the specified accuracy of the PD689.
Allow the meter to warm up for at least
15 minutes before performing the internal calibration procedure.
The Internal calibration menu is part of the Advanced features menu.
1. Press and hold the Menu button for five seconds to access the
Advanced Features of the meter.
2. Press the Up arrow button to scroll to the Internal calibration menu
(ICAL) and press Enter/Ack.
3. The meter displays 4.000 mA. Apply a 4.000 mA signal and press
Enter/Ack. The display shows both trend arrows for a moment
while the meter is accepting the signal.
4. After the signal is accepted, the meter displays 8.000 mA. Apply an
8.000 mA signal and press Enter/Ack. The display shows both
trend arrows for a moment while the meter is accepting the signal.
5. Continue, as in the previous step, for the remaining signals:
12.000 mA, 16.000 mA, and 20.000 mA.
Error Message (Error)
An error message indicates that the calibration or scaling process was
not successful. After the error message is displayed, the meter reverts
to the previous signal prompt, allowing the appropriate input signal to be
applied. The error message might be caused by inadvertently leaving
the signal at the previous level.
