Introduction
The PD6907 ProtEX+ loop-powered explosion-proof
& intrinsically safe feet and inches meters can be
installed virtually anywhere to provide convenient and
informative display of any 4-20 mA signal. They can
operate down to -40°C and be installed in areas that
get as cold as -55°C, however the display will cease
functioning. One of the most convenient features of
these instruments is their dual-line display. The top
display is used to display level in feet and inches
while the 8-character alphanumeric bottom display
can be used to display a tag or custom message.
Another common setup is to display the input in feet
and inches on the top display and in another scale on
the bottom display (such as the volume in gallons).
The bottom display line uses 14-segment
alphanumeric characters that provide much clearer
indication of tags, units, or alarm messages than
7-segment characters do.
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 (4.7 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, IP68
explosion-proof enclosure, an operating temperature
range of -40 to 167°F (-40 to 75°C), conformally
coated PCBs, and a backlit LCD that can be read in
bright sunlight or dimly lit areas.
The ProtEX+ Series is CSA Certified as ExplosionProof / Dust-Ignition Proof / Flame-Proof and ATEX
and IECEx Certified as Intrinsically Safe. The
enclosure itself is ATEX, IECEx, CSA, and UL
approved.
Free, PC-based, MeterView XL software that
connects to the meter via a micro USB cable is
available for programming and setup of the meters.
For more details, see the MeterView XL manual. Four
CapTouch through-glass buttons are available to
operate the instrument without removing the cover.
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
input 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
control, or pump alternation.

Key Features
2X More Informative Display
The PD6907 display offers a 50% larger display area
and is twice more informative than previous
generations of loop-powered explosion-proof meters.
Featuring an alphanumeric dual-line display and a
20-segment bargraph, reading and understanding
process values is easy and intuitive. The addition of
status indicators provides a quick glance at alarm
conditions, relays, process trends, and more.
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.
Backlight Turns Red on Alarm
When an alarm occurs, the display can be
programmed to turn red, flash, and display an alarm
indicator . In addition, a unique custom alarm
message for each of the two relays and two open
collectors can be displayed on the bottom display.
These features can be activated even if no relay or
open collector is connected.
CapTouch Through-Glass
Buttons
The PD6907 is equipped with four capacitive sensors
that operate as through-glass buttons so that it can be
operated without removing the cover (and exposing
the electronics) in a hazardous area. CapTouch
buttons are designed to work under any lighting
condition and to protect against false triggering. They
can be disabled for security via a switch on the
display module.
CapTouch buttons have two modes of operation:
Normal and Delayed. Delayed mode prevents
accidental trigger of the buttons. In the Delayed
mode, the buttons enter into a low sensitivity state
(sleep) and they ignore quick button presses after 20
seconds of inactivity. To wake up the buttons, press
and hold any button for more than 2 seconds, the
buttons respond normally.

Feet & Inches Display with
Bargraph
Designed for users that prefer to read level in feet and
inches instead of a decimal format, the PD6907 can
display level up to 999FT 11IN & 15/16 on the top
display. The bottom display can toggle between a tag
(Tank 4) and units (Gallons), and if dual-scale mode
is enabled, then the input can be displayed in a
different scale such as volume (17,500).
Predefined and Custom Units
The meter has six available preprogrammed unit
classes when programming PV2: 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.
14-Segment Characters
Notice how much better letters like “T”, “N” and “K”
appear as 14-segment characters on the bottom display
vs. 7-segment characters found on other meters.
Password Protection
A password can be set up for programming security to
prevent unauthorized changes to the programmed
parameter settings.
Enable / Disable Backlight
The backlight may be enabled or disabled using the
System - Backlight menu. The backlight is enabled by
default, but the input must be wired appropriately for
the backlight to function. See Enabling or Disabling
the Backlight (BACKLITE) on page 61 for details.
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.
Free MeterView XL
Programming Software
The fastest and easiest way to program the meter is
using the free Meterview XL programming software.
This software greatly simplifies the programming
process and allows the user to save configuration files
for later use.
The meter connects to the PC via a provided microUSB cable and is powered by the USB connection, so
no additional power is needed during programming.
Wide Viewing Angle
The window and display module have been optimized
to provide a wide viewing angle of approximately
±40°; nearly twice that of the competition. Plus, the
display module can be rotated in 90° increments
providing added mounting flexibility.

Modern and Practical Enclosure
The PD6907 NEMA 4X, IP68 enclosure provides
serious protection from the elements, high impact,
corrosion, and electrical interference. Plus, the
extensive worldwide agency approvals allow it to be
installed virtually anywhere.
Aluminum or Stainless Steel Enclosure
The enclosure is available in copper-free (0.3%),
die-cast aluminum and type 316 stainless steel.
Built-In Flange for Pipe Mounting
The built-in mounting flange allows easy mounting to
walls or pipes.
A slot on the back makes it easy to center the unit on
a pipe. There are two ¾" NPT threaded conduit holes
for wiring.
Grounding Screw
A grounding screw is provided on the top of the
enclosure.
SS Tag Attaching Loop
The enclosure is also equipped with a loop at the top
to easily attach a PDA-SSTAG stainless steel tag.
Tamper-Proof Capability
The instrument can be made tamper-proof by
inserting a wire through the built-in loop on the base
of the enclosure and a hole in the lid of the enclosure
and securing this wire with a lead seal.

Pump Alternation
The PD6907 can be used as a pump controller to
alternate two pumps and indicate high and low alarm
conditions. The pumps can be programmed to
alternate on level and runtime and the display can be
programmed to turn red and flash a message on
alarm conditions. The meter can display the pump
runtimes and the number of times they have cycled.
See the Pump Control with Alternation & Alarm
Example on page 48 for full details.
Relay #2 turns the main pump on at 30 feet and turns
it off at 10 feet. lights up to show relay 2 is
energized. The indicates level is rising.
With the Pump Alternation feature activated, the next
time the level reaches 30 feet, relay #1 transfers and
starts the backup pump. lights up to show relay 1
is energized.
Easy Wiring & Service
The PD6907 has been designed for easy wiring and
servicing. All connections are made to removable
screw terminal blocks. There are no exposed printed
circuit boards.
Input Signal Conditioning
The Function menu is used to select the input signal
conditioner applied to the input: linear or round
horizontal tank volume calculation. Multi-point
linearization 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
Up to 32 linearization points can be selected for PV1
and PV2 under the linear function. Multi-point
linearization can be used to linearize the input so the
meter can display volume from non-linear tanks or to
convert level to flow using weirs and flumes with
complex equations to convert level to flow using weirs
and flumes with complex equations.
If the dual-scale level feature has been selected, the
menus for PV1 & PV2 are enabled.
Round Horizontal Tank
Linearization
This function automatically calculates the volume in a
round horizontal tank with flat ends and allows that
reading to be displayed on the bottom display. This
results in a meter that displays the height of the tank
in convenient to read feet and inches on the top
display and volume on the lower display. The user
only needs to enter the diameter and length of the
tank and the meter takes care of the rest.

Setup and Programming
The meter is factory calibrated prior to shipment to display
0.00 to 100.00, which corresponds to the 4-20 mA input.
The calibration equipment is traceable to NIST standards.
Overview
There are no jumpers to set; setup and programming
is done through the CapTouch buttons or the free
MeterView XL PC-based software.
The meter may be powered via the micro-USB
connection located on the display module for the
purpose of programming only. The backlight will not
work while the meter is powered via the USB
connection.
CapTouch Buttons
The PD6907 is equipped with four capacitive sensors
that operate as through-glass buttons so that it can be
programmed and operated without removing the
cover (and exposing the electronics) in a hazardous
area.
These buttons can be disabled for security by
selecting the Lock setting on the switch located on the
side of the display module, close to the Menu button.
To actuate a button, press one finger to the glass
directly over the marked button area. When the cover
is removed, the CapTouch buttons can be used after
the meter completes a self-calibrating routine (hand
symbol flashes). The sensors are disabled when more
than one button is pressed, and they will automatically
re-enable after a few seconds (hand symbol off).
CapTouch Buttons Delay
The CapTouch have two modes of operation: Normal and
Delayed. Use the Delayed mode to prevent accidental
trigger of the buttons. In the Delayed mode, the buttons
enter into a low sensitivity state (sleep) and they ignore quick
button presses after 20 seconds of inactivity. To wake up the
buttons, press and hold any button for more than 2 seconds,
the buttons respond normally.
Disabling the CapTouch Buttons
The CapTouch buttons can be disabled by moving the slide
switch, located on the display module to the Lock position;
see the image below.
CapTouch Button Tips & Troubleshooting
The CapTouch buttons are designed to work under
any lighting condition and to protect against false
triggering. If the CapTouch buttons are not needed
during operation, they can be disabled (slide switch to
Lock).
• To remove cover with power applied (safe area
only), or to clean the window, place your hand
over the buttons; this will temporarily disable the
CapTouch buttons to prevent inadvertent use.
• Keep the glass window clean.
• Tighten the cover securely.
• Use a password to prevent tampering.
• CapTouch buttons will not work if two or more
buttons are detected as being pressed
simultaneously. Be careful to avoid triggering
multiple buttons or reaching across one button
location to press another.

MeterView XL Programming Software
The fastest and easiest way to program the meter is
using the free Meterview XL programming software.
This software greatly simplifies the programming
process and allows the user to save configuration files
for later use.
The meter connects to the PC via a provided microUSB cable and is powered by the USB connection, so
no additional power is needed during programming.
To download the latest MeterView XL programming
software and manual, visit predig.com/meterviewxl.
• The meter should only be connected to a
computer while it is located in a safe area.
• Care should be exercised to avoid ground loops
when connecting the USB to an active loop (e.g.
power supply, transmitter, loop-powered meter,
etc.). It is recommended to connect the (mA+)
terminal of the meter to the (-) terminal of a twowire transmitter and the (mA-) to the (+) of the
next device in the loop or to the (-) terminal of the
power supply.

Scaling the 4-20 mA Input (INPUT)
It is very important to read the following information before proceeding to program the meter:
• The meter is factory calibrated prior to shipment to display 0.00 to 100.00 FT, which corresponds to the 4-20 mA
input. The calibration equipment is traceable to NIST standards.
• A calibrated signal source is not needed to scale the meter.
Enter the Input menu to scale the meter to display the 4-20 mA input. The input can accept any signal from
4 to 20 mA.

Setting Custom Units (CUSTOM)
When the desired unit class or unit of measure within a class for PV2 is not available, a custom unit may be programmed.
Select the CUSTOM menu (or CUSTOM unit within a unit class) to enter a custom unit name.
Text values are set using the Right and Up-Arrow buttons. Press Right-Arrow to select next character and
Up-Arrow to increment character value. The selected character will flash. Press and hold the Up or Right-Arrow
buttons to auto-increment or decrement the character. Press Enter to accept the character.
Notes:
• Press and hold the Right-Arrow while no character is being edited to erase all characters to the right of the
flashing character
• Press and hold Up or Right-Arrow to auto-increment or decrement a selected character.
• All text values, including tags and alarm messages, are set in a similar fashion.
Scaling Example
The 4-20 mA input can be scaled to the appropriate values for a given application. The 4 mA input
(input 1) should have a corresponding display value (display 1) which represents the low end of the process value
range being measured by the transmitter. Likewise, the 20 mA input (input 2) should have a display value (display 2)
which represents the high end of the process value range.
For example: If the meter is used to display the level of a 100 ft tall tank, the transmitter should send a 4 mA signal
when the tank is empty and a 20 mA signal when the tank is full. The meter should be programmed to interpret these
inputs on a display range of 0-100, so that at 4 mA the meter will display 0 and at 20 mA the meter will display 100.
Processes which require a non-linear scale can be accommodated using multi-point linearization (LINEAR) and
round horizontal tank (RH TANK) functions available in the Advanced menu. See Input Signal Conditioning Functions
(FUNCTN), page 52.
A signal source is not needed to scale the meter; simply program the inputs and corresponding display values.
• Reverse Scaling
The meter can be scaled so that 4 mA represents the high end of the process value range being measured by
the transmitter and 20 mA represents the low end of the process value range.

Setting the Display Features (DISPLAY)
The meter’s display functions may be programmed using the Display menu. This menu consists of the following
submenus: Units, Decimal Point, Comma, Bargraph, Top, and Bottom.
Changing the Engineering Units (UNITS)
The UNITS menu is used to change how fractional inches are represented. The options are automatically reducing, 1/16,
1/8, 1/4, 1/2 of an inch, or no fractions. The default setting (FT-IN/*) automatically reduces the fraction to the lowest
denominator.
When in dual-scale mode, it is possible to change the PV 2 display units within the selected unit class without the
need to re-scale the meter. When selecting a new unit from within the DISPLAY menu (e.g. changing from gallons
(GAL) to liters (L)), the meter will automatically convert the display values to display the new unit. Enter the UNITS
menu, select a new unit of measure from the list of predefined units, and press the Enter button. If entering a custom
unit (CUSTOM), the input must be scaled using the custom unit.
Changing the Decimal Point (DEC.PT)
The decimal point may be set with up to seven decimal places or with no decimal point at all.
Pressing the Right-Arrow moves the decimal point one place to the right until no decimal point is displayed, and then
it moves to the left most position. Pressing the Up-Arrow moves the decimal point one place to the left.
If the dual-scale level feature is selected, the decimal point selections for PV2 are enabled.

default if a numeric value is being displayed. This
feature can be disabled or enabled using the Comma
menu.
Note: This menu is only available if the meter is in
dual-scale mode.

Programming the Bargraph (BARGRAPH)
The meter comes equipped with a bargraph display for applications where a visual representation of the process
variable’s percentage of full scale is desirable. This feature can be enabled or disabled using the Bargraph menu
(BARGRAPH). The value displayed on the bargraph can be the percentage of full scale (PV PCT) or the percentage of
a user-programmable range (PV). If the meter is in dual-scale mode, the bargraph can be assigned to display either
PV1 or PV2 using this menu.
Programming the Outputs (OUTPUT)
All models come with two open collectors. Depending on the model purchased, the meter may include two solid-state
relays, and one 4-20 mA output. The Output menu will only show options for the available outputs. See Ordering
Information on page 11 for details.
Page 39
PD6907 Ex-Proof & I.S. Loop-Powered Feet & Inches Meter
Instruction Manual
39
Open Collector Outputs
(OPEN COLLECTR)
The meter is equipped with two NPN open collector outputs as a standard feature that may be set up for pulse
outputs, alarms, timed pulses, or disabled.
Pulse outputs can be set to transmit the PV value (PV1 or PV2 if meter is in dual-scale mode). Output 2 may be used
to generate a quadrature output based on the other open collector output. An output test mode is also selectable to
generate pulses at a constant programmable frequency.
Alarms are available based on the PV value or the digital input. The alarm status will show on the display even if the
output is not wired.
A timer output (TIMER) turns the open collector on and off at the specified time intervals. The timer can be set as
single-shot or continuous timer.
The stopwatch output (STPWATCH) allows the open collector to be manually activated by starting the stopwatch. The
stopwatch count can be displayed on the top or bottom display.
The output may be disabled by selecting DISABLE.
The Open Collector Outputs are programmed in the following manner:
Page 40
PD6907 Ex-Proof & I.S. Loop-Powered Feet & Inches Meter
Instruction Manual
40
Pulse Output (PULSE)
The pulse outputs may be programmed to generate a scaled frequency based on the PV and a programmable factor.
The factor determines the number of pulses per second generated per unit of measure. For example, if the meter
display shows 100 gallons and the factor is set to 2, the number of pulses generated per second would be 200. The
maximum frequency is 1,000 Hz.
Setting output 2 to quadrature will duplicate the other open collector output, but lag by 90 degrees out of phase. The
other output should be programmed as desired for the quadrature output function and must be a pulse (PULSE)
output selection. The quadrature maximum frequency for both outputs is 500 Hz.
The TEST option will output a fixed number of pulses per second based on the FREQ value entered.
Page 41
PD6907 Ex-Proof & I.S. Loop-Powered Feet & Inches Meter
Instruction Manual
41
Alarm (ALARM)
Alarm outputs may be assigned to the PV or the digital input. When assigned to the PV, the alarm may be set as
either a high alarm or a low alarm. Alarm actions (AUTO, AUTO.MAN, LATCH, L-CLEAR) determine how and when the
alarm should be reset. They operate as follows:
• Automatic (AUTO): Alarm will reset automatically once the alarm condition has cleared.
• Automatic/Manual (AUTO.MAN): Alarm will reset automatically once the alarm condition has cleared but can
also be reset using the Enter (ACK) button (or whichever function key is set to acknowledge) at any time.
• Latching (LATCH): Alarm must be reset manually and can be done so at any time. Press the Enter (ACK)
button at any time to clear the alarm.
• Latching with Reset after Clear (L-CLEAR): Alarm must be reset manually and can only be done so after
the alarm condition has cleared. Press the Enter (ACK) button after the alarm condition has cleared to reset
the alarm.
If the alarm is set to PV, a set and reset point must be programmed. The set point is the display value at which the
alarm will turn on and the reset point is the display value at which the alarm will turn off. If the set point is lower than
the reset point, the alarm will be a low alarm; if the set point is higher than the reset point, the alarm will be a high
alarm. The digital input alarm will trigger whenever the digital input is triggered.
For both the PV and digital input alarms, a delay before the alarm is turned on or off may be set, as well as a fail-safe
feature which reverses the on/off operation of the open collectors.
Alarm states will be displayed on the meter even if no open collector output is physically connected. These may
include a red LED backlight, flashing PV value (PV alarm only), a programmable alarm message, an alarm
indicator , and flashing bargraph segment.

Flashing Red Alarm (RED)
The last two lines in the preceding menu flow chart show how to program the display to turn red, flash, and display a
message when an alarm occurs.
Timer (TIMER)
The timer output may be set to generate the timed pulse only once (ONESHOT) or continuously (CONT).
The timer output produces a constant width pulse at a constant frequency, if set as continuous timer. Program the Off
Delay (OFF.DLAY) from 1 second to 99 hours 59 minutes and 59 seconds. This is the time it takes from selecting
START to turning on the output and for how long the output is off in continuous mode.
Program the On Time (ON TIME) for the active low pulse from 1 second to 99 hours 59 minutes and 59 seconds
(pulse width). This is the period of time for which the output will remain on.
Select Start (START) to begin outputting the constant timed pulse.
Select Stop (STOP) to end outputting the constant timed pulse.
Function keys or the digital input may be assigned to start and stop timer functions (see the USER menu in the
Advanced Menu).

Stopwatch (STPWATCH)
The stopwatch function may be used to manually run and control a process for a specific time interval up to 99 hrs.,
59 min, and 59 seconds. The stopwatch function may be assigned to any open collector. There are three settings
needed to use the function effectively.
1. Assign stopwatch to either top or bottom display
2. Assign the open collector to control the
process (on/off)
3. Assign a function key or digital input to start/stop the stopwatch
Application Example
To maintain consistency of a product, it is necessary to take and test samples at different times throughout the day.
The stopwatch function is used to open and close a solenoid valve to know the exact amount of time needed to
complete the desired sample. Once this is determined, the timer function can be used to automatically take a sample
(batch) based on the time determined using the stopwatch function.
Setup: Assign the following to Stopwatch Function
• Bottom display
(see pages 35 & 37 for details how to change the display)
• Relay 1
(see pages 38 & 44 how to change Open Collector and Solid-State Relay functionality)
• F3: Start/Stop
(see pages 58 & 59 for details on how to change the function keys)
Procedure
• Press F3 to start the stopwatch; relay 1 turns on and the process starts running.
• Press F3 to stop the stopwatch; relay 1 turns off and the process stops.
• The bottom display indicates the time it took to complete the sample.

Solid-State Relay Outputs (RELAY)
The meter can be optionally equipped with two solid-state relays that may be set up for alarms, timer, stopwatch, or
pump control. Alternatively, they may be disabled.
Alarms are available based on the PV value or the digital input. The alarm status will show on the display even if the
output is not wired.
Pump control allows the relay to turn on and off a pump at specified on and off points. This can be done using only
one of the relays to control one pump (ON-OFF) or using both relays in tandem to alternate between two pumps
(ALTERN).
A timer output (TIMER) turns the relay on and off at the specified time intervals. The timer can be set as single-shot
or continuous timer.
The stopwatch output (STPWATCH) allows the relay to be manually activated by starting the stopwatch. The
stopwatch count can be displayed on the top or bottom display.
The output may be disabled by selecting DISABLE.
• During setup, the relays do not follow the input and they will remain in the state found prior to entering the
Relay menu.

Alarm (ALARM)
Alarm outputs may be assigned to the PV or the digital input. When assigned to the PV, the alarm may be set as
either a high alarm or a low alarm. Alarm actions (AUTO, AUTO.MAN, LATCH, L-CLEAR) determine how and when the
alarm should be reset. They operate as follows:
• Automatic (AUTO): Alarm will reset automatically once the alarm condition has cleared.
• Automatic/Manual (AUTO.MAN): Alarm will reset automatically once the alarm condition has cleared but can
also be reset using the Enter (ACK) button (or whichever function key is set to acknowledge) at any time.
• Latching (LATCH): Alarm must be reset manually and can be done so at any time. Press the
Enter (ACK) button at any time to clear the alarm.
• Latching with Reset after Clear (L-CLEAR): Alarm must be reset manually and can only be done so after
the alarm condition has cleared. Press the Enter (ACK) button after the alarm condition has cleared to reset
the alarm.
If the alarm is set to PV, a set and reset point must be programmed. The set point is the display value at which the
alarm will turn on and the reset point is the display value at which the alarm will turn off. If the set point is lower than
the reset point, the alarm will be a low alarm; if the set point is higher than the reset point, the alarm will be a high
alarm. The digital input alarm will trigger whenever the digital input is triggered.
For both the PV and digital input alarms, a delay before the alarm is turned on or off may be set, as well as a fail-safe
feature which reverses the on/off operation of the relays.
Alarm states will be displayed on the meter even if no relay output is physically connected. These may include a red
LED backlight, flashing PV value (PV alarm only), a programmable alarm message, an alarm indicator , and
flashing bargraph segment.

Pump Control (PUMPCTRL)
The pump control output is used in situations where the relays are used to control pumps. There are two options
available for controlling pumps: on-off (ON-OFF) and pump alternation (ALTERN).
ON-OFF will turn the relay on at a programmed on point and off at a programmed off point. Setting the on point higher
than the off point will make the output activate on a high PV value; setting the on point lower than the off point will
make the output activate on a low PV value. The relay will reset automatically.
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 alternately. 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 alternate between two similar pumps.
The ALTERN menu is only available under Output 1 and will automatically set Output 2 to pump alternation as well.
Use the pump Alternation Time setting (ALT.TIME) to control the alternation based on runtime in addition to level
cycles.
On/Off Pump Control (ON-OFF)
When programming a single pump to turn on and off, the on and off points must be programmed. The relay will
activate at the on point and deactivate at the off point. On and off delays may be programmed to delay the activation
or deactivation of the relay by a certain number of seconds after reaching either the on point or off point.
Page 47
PD6907 Ex-Proof & I.S. Loop-Powered Feet & Inches Meter
Instruction Manual
47
Pump Alternation (ALTERN)
Pump alternation sets the two relays to alternate every time the first on point (ON 1) is reached. The active relay will
turn off once the first off point (OFF 1) is reached. If the PV reaches the second on point (ON 2), the other relay will
also turn on. The second relay will turn off once the second off point (OFF 2) is reached and the first relay will remain
active until the first off point (OFF 1) is reached.
On and off delays may optionally be programmed for each on and off point to delay the activation or deactivation of
the relays by a certain number of seconds after reaching either the on point or off point.
For pumps that typically remain on extensively, the alternation time (ALT.TIME) parameter sets a period of relay ontime after which the relays should alternate. For example, if the alternation time is set to one hour, pump 1 will turn off
after one hour of runtime regardless of the level reading, at which point pump 2 becomes the active pump. Pump 2
will run until one hour has passed, or the tank has reached a desirable level; whichever happens first. By using the
proper on/off points, the alternation can be set up so that the first pump on is the first pump off. This is desirable when
the two pumps are of similar rating.

it off at 10 feet. lights up to show relay 2 is
energized. The indicates level is rising.
With the Pump Alternation feature activated, the next time
the level reaches 30 feet, relay #1 transfers and starts the
backup pump. lights up to show relay 1 is energized.
If the backup pump is not able to keep up, and the
level reaches 35 feet, relay #2 transfers and starts the
main pump as well. Open collector #1 trips the High
Level Alarm, the display turns red and flashes “Hi
Level” message, and indicates an alarm condition.
The High Level Alarm resets at 34 feet.
Once the level has dropped below the reset points, both
relays will turn off. If the Main Pump fails to turn off, open
collector #2 trips the Low Level Alarm at 5 feet to warn
against the pump running dry. The Low Level Alarm resets
at 6 feet.

Timer (TIMER)
The timer output may be set to generate the timed pulse only once (ONESHOT) or continuously (CONT). The timer
output produces a constant width pulse at a constant frequency, if set as continuous timer.
Program the Off Delay (OFF.DLAY) from 1 second to 99 hours 59 minutes and 59 seconds. This is the time it takes
from selecting START to turning on the output and for how long the output is off in continuous mode.
Program the On Time (ONTIME) for the active low pulse from 1 second to 99 hours 59 minutes and 59 seconds
(pulse width). This is the period of time for which the output will remain on.
Select Start (START) to begin outputting the constant timed pulse. Select Stop (STOP) to end outputting the constant
timed pulse. Function keys or the digital input may be assigned to start and stop timer functions (see the USER menu
in Advanced).
Stopwatch (STPWATCH)
The stopwatch function may be used to manually run and control a process for a specific time interval up to 99 hrs.,
59 min, and 59 seconds. The stopwatch function may be assigned to any relay. There are three settings needed to
use the function effectively.
1. Assign stopwatch to either top or bottom display
2. Assign the relay to control the process (on/off)
3. Assign a function key or digital input to start/stop the stopwatch
Application Example
To maintain consistency of a product, it is necessary to take and test samples at different times throughout the day.
The stopwatch function is used to open and close a solenoid valve to know the exact amount of time needed to
complete the desired sample. Once this is determined, the timer function can be used to automatically take a sample
(batch) based on the time determined using the stopwatch function.
Setup: Assign the following to Stopwatch Function
• Bottom display
(see pages 35 & 37 for details how to change the display)
• Relay 1
(see pages 38 & 44 how to change Open Collector and Solid-State Relay functionality)
• F3: Start/Stop
(see pages 58 & 59 for details on how to change the function keys)
Procedure
• Press F3 to start the stopwatch; relay 1 turns on and the process starts running.
• Press F3 to stop the stopwatch; relay 1 turns off and the process stops.
• The bottom display indicates the time it took to complete the sample.

Runtime & Cycle Count (INFO)
The relay information menu shows runtime and cycle count for each relay. These values may be cleared at any time
by selecting the Clear option (CLEAR?).
Isolated 4-20 mA Output (4-20 mA)
The 4-20 mA menu is used to scale the isolated 4-20 mA output based on display values. This menu is not present
on models without a 4-20 mA output option.
The 4-20 mA analog output can be scaled to provide a 4-20 mA signal for any PV display range or to simply
retransmit the 4-20 mA input. The output may be disabled (DISABLE), and will only output the minimum signal.
Overrange and underrange values determine what mA signal the meter will output if the mA input is underrange
(<3.5 mA) or overrange (>20.5 mA). This value may be set to 1 mA, 3.5 mA, 3.8 mA, 20.5 mA, 20.8 mA, 23 mA, or
disabled.
No equipment is needed to scale the analog output; simply program two display values and corresponding mA output
signals.
Process Variable (PV)
To scale the analog output, enter display value 1 and a corresponding analog output value for this display, and enter
display value 2 and a corresponding analog output value for this display value. This will provide a scaled linear
analog output.
Retransmit (RETRANS)
This option will retransmit the 4-20 mA analog input without the need to scale the output.
Output Manual Control (CONTROL)
The Control menu is used to control the open collector outputs, 4-20 mA analog output, and the relays manually,
ignoring the input. Each open collector, relay, and analog output can be programmed independently for manual
control. Selecting automatic control sets all relays and analog output for automatic operation.
After selecting manual control for a specific output, you can set the output value. To change the output value, return
to the Control menu, select the output to control, select manual control, and enter a new value.

Multi-Point Linearization (LINEAR)
Up to 32 linearization points can be selected for PV1 and
PV2 under the LINEAR function. Multi-point linearization
can be used to linearize the input so the meter can display
volume from non-linear tanks or to convert level to flow
using weirs and flumes with complex equations. These
points are established via direct entry (SCALE) or with a
live calibration signal source (CAL).
If the dual-scale level feature has been selected, the
menus for PV1 & PV2 are enabled.

Advanced Scaling and Calibration (SCALE.CAL)
This menu offers options to scale or calibrate the meter.
Scaling the Input (SCALE)
The scale menu in the Advanced menu is the same as the scale menu in the Input menu. See Scaling the 4-20 mA
Input (INPUT) on page 33 for details about scaling the meter.
Calibrating the Input (CAL)
To scale the meter without a signal source, refer to
Scaling the 4-20 mA Input (INPUT) on page 33.
The meter can be calibrated to display the process in engineering units by applying the appropriate input signal and
following the calibration procedure. The CAL menu can be used either with a calibrated current source or with a live
signal coming from a 4-20 mA transmitter connected to the process being measured.
During calibration, the mA input value will be displayed as INP 1 and INP 2. Adjust the input source until the
desired mA value is shown.
The use of a calibrated signal source is required.
Follow these steps to calibrate the input:
1. After accessing the SCALE.CAL menu, press the Right-Arrow button to scroll to the Calibration menu (CAL
PV) and press Enter.
2. Select the appropriate units for the desired process variable, then press Enter. For information on units, see
Available Unit Classes and Units on page 34.
3. The meter displays INP 1. Apply a known signal and press Enter. The display will flash while accepting the
signal.
4. After the signal is accepted, the meter displays DSP 1. Enter a corresponding display value for the input
signal, and press Enter to accept.
5. The meter displays INP 2. Apply a known signal and press Enter. The display will flash while accepting the
signal.
6. After the signal is accepted, the meter displays DSP 2. Enter a corresponding display value for the input signal
and press Enter to accept.
7. After completing calibration, the SAVE? display will need to be acknowledged using the Enter key before
calibration will take effect.
Note: The SAVE? prompt is not displayed if no changes have been made to the scaling.

Low-Height Cutoff (CUTOFF)
The low-height 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 cutoff value may be programmed from
0.1 to 99999. The meter will display zero below the cutoff value. The cutoff can be disabled to display negative
values.
Noise Filter (FILTER)
The noise filter is available for unusually noisy signals that cause an unstable process variable display. The noise
filter averages the input signal over a certain period of time. The filter level determines the length of time over which
the signal is averaged. The filter level can be set between 1 and 16 seconds or turned off. The higher the filter level,
the longer the averaging time and so the longer it takes the display to settle to its final value. Setting the filter level to
off disables the filter function.
Noise Filter Bypass (BYPAS)
The noise filter bypass changes the behavior of the meter so that small variations in the signal are filtered out but
large abrupt changes in the input signal are displayed immediately. The bypass value determines the minimum
amount of signal change to be displayed immediately. All signal changes smaller than the bypass value are filtered or
averaged by the meter. The noise filter bypass may be set between 0.1 and 99.9% of full scale.
Enabling Password Protection (PASSWRD)
The Password menu is used for programming security to prevent unauthorized changes to the programmed
parameter settings.
To set a password, enter the Password menu and program a five-digit password. When a password has been
enabled, the lock icon will display in the upper-left side of the display. For instructions on how to program numeric
values see Setting Numeric Values on page 32.
Making Changes to a Password Protected Meter
If the meter is password protected, the meter will display the message LOCKED when the Menu button is pressed.
Press the Enter button while the message is being displayed and enter the correct password to gain access to the
menu. After exiting Programming Mode, the meter returns to its password protected condition.
Disabling Password Protection
To disable password protection, access the Password menu and clear the entered password either by pressing and
holding the Right Arrow button until all digits reset to zero or manually changing all the digits to zero. When the Enter
button is pressed, the meter will display UNLOCKD and will no longer require a password to access Programming
Mode.
Note: If the meter is password protected and the password has been forgotten, the password may be overridden
using the master password: 50865

the displayed amount to make the displayed value
zero. Reset tare removes the display offset of the net
value, and the gross and net values become the
same until a new capture tare is entered.
Program a function key or the digital input for the tare
and reset tare.

Changing System Settings (SYSTEM)
The System menu contains the following menus:
Analog Output Calibration, Restore Factory Defaults,
Dual-Scale (PV2), Backlight, CapTouch Buttons
Operation Mode, Information, and Internal Calibration.
Note: The Analog Output Calibration menu is
available only if the option is installed.
Analog Output Calibration (AOUTCAL)
To perform the analog output calibration, it is
recommended to use a milliamp meter with a
resolution of at least 0.1 µA to measure the output
current. The values saved internally during this
procedure are used for scaling the 4-20 mA output in
the Setup menu.
4-20 mA Output Calibration Procedure
1. Go to the Advanced Features menu and
navigate to the SYSTEM menu and press
Enter. Navigate to AOUTCAL and press Enter.
2. The display will show 4 mA. The ProtEX+ mA
output should now be close to 4 mA. Enter the
actual value read by the digital mA meter on
the bottom display and press Enter.
3. The display will show 20 mA. The ProtEX+ mA
output should now be close to 20 mA. Enter
the actual value read by the digital mA meter
on the bottom display and press Enter.
4. The ProtEX+ will now calculate the calibration
factors and store them.
5. Press Menu to exit.
Enabling the Dual-Scale Feature (PV2)
Dual-Scale Mode
Top Display: Toggling Between Process Variable and Units
Bottom Display: Toggling Between Process Variable
(in different scale) and Different Units
For some level applications, such as displaying the
height and volume of a tank, a second PV can be
enabled which can be scaled to display a different
value based on the same 4-20 mA input. This is
accomplished by enabling the dual-scale feature
(PV2).
When the dual-scale feature is enabled, additional
menus will be displayed to allow for the programming
of the second PV. The input menu will display PV1
and PV2 for scaling and the display menu will allow
both PVs to be displayed on either top or bottom
display, for example. See Display Functions &
Messages on page 28 for additional information on
where additional dual-scale specific menus will
appear.
PV2 must be enabled to use the Round Horizontal
Tank feature. See Round Horizontal Tank
Linearization (RH TANK) on page 55.
For instructions on how to enable PV2 see Changing
System Settings (SYSTEM) on page 60.

The backlight may be enabled or disabled using the
System - Backlight menu. The backlight is enabled by
default, but the input must be wired appropriately for
the backlight to function. See Wiring Diagrams on
page 23.
CapTouch Buttons Operation Mode (CAPTOUCH)
CapTouch buttons have two modes of operation:
Normal and Delayed. Delayed mode prevents
accidental trigger of the buttons. In the Delayed
mode, the buttons enter into a low sensitivity state
(sleep) and they ignore quick button presses after 20
seconds of inactivity. To wake up the buttons, press
and hold any button for more than 2 seconds, the
buttons respond normally.
Viewing System Information (INFO)
System information, such as software (firmware)
number and version, model number, and system tag,
may be viewed in the INFO menu. Press the Right
Arrow button to cycle through all available meter
information. Press Menu to go back to the previous
menu.
Calibrating the Internal mA Reference (ICAL)
The meter is factory calibrated prior to shipment to display
0.00 to 100.00, which corresponds to the 4-20 mA input.
The calibration equipment is traceable to NIST standards.
The use of calibrated signal sources is necessary to
calibrate the internal source of the meter. The meter’s
internal source is what allows the user to scale the
meter without applying a signal.
Check calibration of the meter at least every
12 months.
Note: Allow the meter to warm up for at least
15 minutes before performing the internal source
calibration procedure.
The Internal Calibration menu is part of the Advanced
menu. Internal Calibration is performed as follows:
1. Press the Menu button to enter
Programming Mode.
2. Press the Up-Arrow button twice and press
Enter to access the Advanced menu.
3. Press the Up-Arrow button and press Enter
to access the System menu.
4. Press the Up-Arrow button and press Enter
to access the ICAL menu.
5. The meter displays low input current
message (4.000 mA). Apply a 4 mA signal
and press Enter. The display flashes for a
moment while the meter is accepting the low
input signal.
6. After the display stops flashing, the display
moves to the high input calibration
(20.000 mA). Apply the high input signal and
press Enter. The display will flash again
while the meter is accepting the high input
signal.

Meter Operation
The meter is equipped with four CapTouch throughglass buttons. These buttons allow meter operation
without removing the cover and exposing the
electronics in a hazardous area.
Three CapTouch buttons labeled F1, F2, and F3 can
be programmed as function keys to perform a variety
of meter functions simply by pressing on the glass
over the button. These include operation of the tare
function, resetting the tare, resetting the meter’s
relays or open collectors, starting and stopping timers,
and displaying max/min values. See Function Keys &
Digital Input Available Settings on page 59 for a
complete list of settings available.
A digital input is available on the meter and it may
function in a similar fashion as the function keys to
allow remote operation of a single task.
The max & min readings (peak & valley) reached by
the process can be displayed either continuously by
assigning it to a display line in the Display menu, or
momentarily by pressing the F1 key (default) or
assign it to any of the other function key or the digital
input.
Pressing the F1 key cycles through various display
values (e.g. max, min); press the Enter key to lock the
display in the current process value and press the
Enter key again to unlock the display.
The relay information menu shows runtime and cycle
count for each relay.
Change the PV2 display units within the selected unit
class at any time without the need to re-scale the
meter. Select the desired units via the UNITS menu in
the DISPLAY menu, and the meter automatically
converts the display values to the new unit of measure.

These buttons can be disabled for security by
selecting the Lock setting on the switch located on the
side of the display module, close to the Menu button.
To actuate a button, press one finger to the glass
directly over the marked button area. When the cover
is removed, the CapTouch buttons can be used after
the meter completes a self-calibrating routine (hand
symbol flashes). The sensors are disabled when more
than one button is pressed, and they will automatically
re-enable after a few seconds (hand symbol off).
CapTouch Button Tips & Troubleshooting
The CapTouch buttons are designed to work under
any lighting condition and to protect against false
triggering. If the CapTouch buttons are not needed
during operation, they can be disabled (slide switch to
Lock).
• To remove cover with power applied (safe area
only), or to clean the window, place your hand
over the buttons; this will temporarily disable the
CapTouch buttons to prevent inadvertent use.
• Keep the glass window clean.
• Tighten the cover securely.
• Use a password to prevent tampering.
• CapTouch buttons will not work if two or more
buttons are detected as being pressed
simultaneously. Be careful to avoid triggering
multiple buttons or reaching across one button
location to press another.

Function Keys Operation
During operation, the programmable function keys
operate according to the way they have been
programmed in the Advanced Features – User menu.
The table under CapTouch Buttons Operation on
page 62 shows the factory default settings for F1, F2,
and F3.
A hint message may be enabled to provide a
description of what each function key does prior to
executing their assigned function. See Enabling the
Function Key Hint Feature (HINT) on page 59.
Digital Input Operation
A digital input is standard on the meter. This digital
input is programmed identically to function keys F1,
F2, and F3. The input is triggered with a contact
closure between DI+ and DI-, or with an active low
signal. During operation, the digital input operates
according to the way it has been programmed in the
Advanced Features – User menu.
Maximum/Minimum Readings
The max & min readings (peak & valley) reached by
the process can be displayed either continuously or
momentarily.
Display momentarily by pressing the F1 function key
(default) or assigning to any of the other function keys
or to the digital input in the User menu.
Display continuously by pressing the Enter button
while the max/min is being displayed to lock the
display. Press Enter again to unlock.
Any of the F1-F3 function keys (buttons) and the
digital input can be programmed to reset the max &
min readings. The meters are set at the factory to
display the max reading by pressing the Right
Arrow/F1 button and to use the Up-Arrow/F2 button to
access the Reset menu. Press the Right Arrow button
to cycle through the available parameters to reset.

Runtime & Cycle Count (INFO)
The relay information menu shows runtime and cycle
count for each relay. These values may be cleared at
any time by selecting the Clear option (CLEAR?). If
the cycle count or runtime values need to be changed
on a frequent basis, it would be convenient to set up a
CapTouch button or the digital input to simplify this
process.
Note: See the menu tree under Solid-State Relay
Outputs (RELAY) on page 44 for complete menu
structure on this feature.

amount of time a relay
has been activated
Meter displaying the
number of times a relay
has cycled
Changing PV2 Engineering Units
It is possible to change PV2’s display units within the
selected unit class without the need to re-scale the
meter. The UNITS menu in the DISPLAY menu allows
the unit of measure to be changed (e.g. from gallons
(GAL) to liters (L)) and the meter will automatically
convert the display values to the new unit of measure.
If entering a custom unit (CUSTOM), the input must be
scaled using the custom unit. See Changing the
Engineering Units (UNITS) on page 36.

Troubleshooting
This product is a highly sophisticated instrument with
an extensive list of features and capabilities. If the
CapTouch buttons are used to program the meter, it
can be a difficult task to keep everything straight. That
is why we strongly recommend the use of the free
MeterView XL software for all programming activities.
A cable is provided to use the MeterView XL software
for programming the meter.
If you have programmed the meter with the CapTouch
buttons and it is not working as intended, try
re-programming the meter using the MeterView XL
software.
Reset Meter to Factory Defaults
When the parameters have been changed in a way
that is difficult to determine what’s happening, it might
be better to start the setup process from the factory
defaults. This can be accomplished using MeterView
XL software or with the CapTouch buttons.
To load factory defaults:
1. Press the Menu button to enter
Programming Mode.
2. Press the Right-Arrow button twice and
press Enter to access the Advanced menu.
3. Press the Up-Arrow button and press Enter
to access the System menu.
4. Press the Right-Arrow button and press
Enter to access the Default menu.
5. Press Enter twice in quick succession. The
meter will load default settings and restart.
Determining Software Version
To determine the software (firmware) version of a
meter:
1. Press the Menu button to enter
Programming Mode.
2. Press the Up-Arrow button twice and press
Enter to access the Advanced menu.
3. Press the Up-Arrow button and press Enter
to access the System menu.
4. Press the Up-Arrow button twice and press
Enter to access the Info menu.
5. Press the Right-Arrow button to cycle
through the meter information. When done,
press the Menu button to return to the
previous menu or press & hold Menu to exit
to Run mode.

Troubleshooting Tips
Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from factory defaults and
use the manual as a step by step programming guide, rather than a random approach to programming. To reset the meter to factory
defaults, see Factory Default Settings on page 65. In addition, for best results, we recommend using the free MeterView XL software
for all programming needs.
Symptom
Check/Action
No display at all
Check:
1. The 4-20 mA current loop is providing at least 3.5 mA to the meter.
2. The voltage drop of all devices connected to the 4-20 mA current loop does not
exceed the max rating of the loop power supply.
Not able to change setup or
programming, LOCKED is
displayed
Meter is password-protected. Enter correct five-digit password to unlock or Master
Password of 50865.
Meter display flashes:
1. 99999
2. -9999
Check that the number of digits required for the scaled value does not exceed the
maximum digits for the display. If it does, try adjusting the decimal point location for less
precision or changing the PV display to the bottom display.
Display is unstable
Check:
1. Input signal stability and value.
2. Display scaling vs. input signal.
3. Filter and bypass values (increase).
Display response is too slow
Check filter and bypass values
Display reading is not accurate
Check:
1. Input signal conditioner selected: Linear, square root, etc.
2. Scaling or calibration
Display does not respond to input
changes, reading a fixed number
Check display assignment. It might be displaying max, min, or set point.
Display shows:
1. MAX and a number
2. MIN and a number
Press Menu to exit max/min display readings.
Relay operation is reversed
Check fail-safe settings in Output menu
Relays do not respond to signal
Check:
1. Relay action in Output menu
