Introduction
These loop-powered 1/8 DIN digital panel meters can
be installed virtually anywhere to provide convenient
and informative display of any 4-20 mA signal. One of
the most convenient features of these instruments is
their dual line display. The top line is used to display
level in feet and inches while the 8-digit alphanumeric
bottom line may be used to display a tag custom mes-
sage. Another common setup is to display the input in
feet and inches on the top line and in another scale
on the bottom line (such as the volume in gallons).
Further enhancing the display on these instruments is
a 20-segment bargraph that also includes a numeric
value of the percentage the bargraph represents.
These loop-powered meters can be installed virtually
anywhere because they get their power from the
4-20 mA loop and therefore require no separate
power source. And they only drop 1.5 V (4.5 V with
backlight), so they add very little burden to the loop.
Additional features that allow these instruments to be
installed virtually anywhere include a NEMA 4X, IP65
front panel, an operating temperature range of
-40 to 167°F (-40 to 75°C) (for safe area products),
conformally coated PCBs, and a backlit LCD that can
be read in bright sunlight or dimly lit areas. Finally,
there are intrinsically safe and nonincendive versions
of these instruments that can be installed in hazard-
ous areas.
Free, PC-based, MeterView XL software that con-
nects to the meter via a micro USB cable is available
for programming and setup of the meters. For more
details, see the LIM6603MVXL manual.
All models come equipped with two open collector
outputs and a digital input. There are also models
available with two solid state relays and isolated
4-20 mA analog output options. The open collector
outputs are useful for alarm indication. The digital in-
put can be used to acknowledge the relays, to
start/stop a timer/stopwatch, and more. The relays
can be programmed for alarm indication, on/off con-
trol, or pump alternation.

Key Features
Informative Display
The Loop Leader’s display provides multiple ways
to help users understand and keep track of their
processes. The most obvious is the dual line which
allows the user to display a numeric value of the
process variable in feet & inches on the top line and
units and/or a tag on the bottom line. There is also a
bargraph that includes a numeric value of the
percentage the bargraph represents.
Predefined display units give users even more display
flexibility. Plus, the high contrast backlit LCD display
is readable from far away and under various lighting
conditions.
Alarm Indication
When an alarm occurs, the Loop Leader's display
can be programmed to turn red. It may also be set
up to flash an alarm message along with the process
variable. The flashing red alarm message can be
activated even if no relay or open collector is
connected.
Feet & Inches Display with
Bargraph
The PD6603/07 Loop Leader meter is designed for
users that prefer to see their level displayed in feet &
inches instead of decimal format. The Loop Leader
can display level to 999FT 11IN & 15/16 on the top
display. The bottom display can toggle between a tag
and units or if dual scale mode is used, can display
the input in a different scale such as volume.
14-Segment Characters
Notice how much better letters like “T”, “N” and “K”
appear as 14-segment characters on the Loop Leader
vs 7-segment characters found on many other meters.

Predefined and Custom Units
The meter has six available preprogrammed unit
classes: volume, height, temperature, pressure,
weight, and rate. When the desired unit class or unit
of measure within a class is not available, a custom
unit may be programmed.
Password Protection
A password can be set up for programming security to
prevent unauthorized changes to the programmed
parameter settings.
Multiple Outputs
•Two open collector outputs (standard)
•Two solid state relays (optional)
•One 4-20 mA output (optional)
The open collector outputs and relays generally
operate in the same manner, with the major exception
being the open collectors are not available for pump
alternation and the relays are not available with pulse
features. The open collectors and relays can be
controlled either automatically or manually.
The isolated analog output signal can be configured
to represent the process variable (PV1, PV2, or
retransmit). It can also be reverse scaled such that
the meter’s high calibration value outputs 4 mA and
the meter’s low calibration outputs 20 mA.
Pump Alternation (ALTERN)
For pump control applications where two similar
pumps are used to control the level of a tank or a well,
it may be desirable to have the pumps operate alter-
nately. This prevents excessive wear and overheating
of one pump over the lack of use of the other pump.
Pump alternation uses both relays in tandem to alter-
nate between two similar pumps. The ALTERN menu
is only available under Output 1 and will automatically
set Output 2 to pump alternation as well.
Pump Alternation Example
The following is an example application where the re-
lays are programmed for pump alternation.

Input Signal Conditioning
Functions (FUNCTION)
The Function menu is used to select the input signal
conditioner applied to the input: linear or round hori-
zontal tank volume calculation. Multi-point lineariza-
tion is part of the linear function selection.
Meters are set up at the factory for linear function with
2-point linearization. The linear function provides a
display that is linear with respect to the input signal.
Multi-Point Linearization
(LINEAR)
Meters are set up at the factory for linear function with
2-point linearization. Up to 32 linearization points can
be selected for PV1 and PV2 under the linear func-
tion. Multi-point linearization can be used to linearize
the display for non-linear signals such as those from
level transmitters used to measure volume in odd-
shaped tanks or to convert level to flow using weirs
and flumes with complex exponent.
If the dual-scale level feature has been selected, the
menus for PV1 & PV2 are enabled.
Round Horizontal Tank
Linearization (RH TANK)
This function automatically calculates the volume in a
round horizontal tank with flat ends. It is only available
for PV2 while the meter is in dual-scale mode.
Set the display for the desired decimal point and engi-
neering units before entering the round horizontal
tank function. Select units (inches or cm) for the tank
dimensions. Enter the diameter and the length in
inches or cm and the results will be calculated auto-
matically in US gallons or liters. The unit of measure
for the volume can be changed using the display
menu.
