INTRODUCTION
The ProtEX-RTP PD6830 is a rugged, explosion-proof, pulse input rate/totalizer for
demanding applications in hazardous areas or in harsh environments. It can be
programmed using the four SafeTouch® through-glass buttons, without removing the
cover, or with four internal push-buttons. The top numeric display will read rate or
total up to five digits and the alphanumeric bottom display will read up to 7 digits,
13 digits with the total overflow feature. The alphanumeric display can also be
programmed to show any combination of numbers and letters up to seven characters
long for rate, total, grand total, engineering units and/or identification tag. The
backlight makes the display more visible in any lighting condition. The enclosure is
provided with threaded conduit holes and integrated pipe or wall mounting flanges.

PASSWORD MENU
OPTIONS
Three programmable password selections can be used for the
following: restrict modification of settings, prevent resetting the
total or grand total without the password, or permanently lock out
the ability to change or reset the grand total or any grand total
related settings (making a non-resettable grand total).
Pass: Restricts modifications of programmed settings to require
re-entering the password to make changes.
Pass T: Restricts the reset of total to require re-entering the
password. Disables the manual mode reset contact.
Pass GT: Restricts the reset of grand total to Require re-entering
the password. May enable a non-resettable grand total and
permanent lockout of grand total-related settings with a specific
password.

overflow display will toggle between the first six digits and last
seven digits (999999 <> 9999999) for a 13-digit total. The total
will rollover beyond thirteen digits. The T indicator on the dis-
play will flash to indicate total overflow, and the six most signif-
icant digits (first six numbers of the total) are indicated with the
flashing overflow symbol .
GRAND TOTAL

PULSE OUTPUT
K-FACTOR
(COUNT)
K-factor (couNT) programmable from 0.000001 to 9999999.
Rate pulses are generated as a scaled output of the rate input
with one output pulse per K-factor (count) number of input
pulses. Total and grand total pulses are generated for every
total or grand total increment selected. (e.g. K-factor value of
100 will generate one pulse every time the total is incremented
by 100 units)
Rate retransmission pulses one to one for input pulses, up to
maximum output speed. K-factor is not used for retransmitting
outputs.
PULSE OUTPUT
PULSE WIDTH
Unless otherwise stated, pulses are 50% duty cycle for re-
quired frequency.
A pulse rate retransmit output will generate 100 to 130 μs
pulses at the falling edge of every input pulse.
PULSE OUTPUT
MAXIMUM
FREQUENCY
5 kHz, pulse width at 50% duty cycle.
If the programming of the outputs would exceed 5 kHz, the
meter will display pUlse OVERRNG
QUADRATURE
OUTPUT
Output set to quadrature will lag the other pulse output by 90°
(1/4 duty cycle) at output frequency. Minimum 1 Hz
TIMER OUTPUT Programmable on and off time, repeating cycle. Minimum pe-
riod 0.1 second, maximum 100,000 seconds. Minimum pulse

Special Conditions for Safe Use:
Use suitably certified and dimensioned cable entry device and/or plug. The
equipment shall be installed such that the supply cable is protected from mechanical
damage. The cable shall not be subjected to tension or torque. If the cable is to be
terminated within an explosive atmosphere, then appropriate protection of the free
end of the cable shall be provided.

SAFETY INFORMATION
WARNINGS
 Read complete instructions prior to installation and operation
of the meter.
 Installation and service should be performed only by trained
service personnel. Service requiring replacement of internal
components (not including battery, if equipped) must be
performed at the factory.
 Disconnect from supply before opening enclosure. Keep cover tight while
circuits are alive. Conduit seals must be installed within 18" (450mm) of
the enclosure.
 Verify that the operating atmosphere of the meter is consistent with the
appropriate hazardous locations certifications.
 If the meter is installed in a high voltage environment and a fault or
installation error occurs, high voltage may be present on any lead

INSTALLATION
For Installation in USA: The PD6830 must be installed in accordance with the
National Electrical Code (NEC) NFPA 70.
For Installation in Canada: The PD6830 must be installed in accordance with the
Canadian Electrical Code CSA 22.1.
For European Community: The PD6830 must be installed in accordance with the
ATEX directive 94/9/EC and the product certificate Sira 10ATEX1116X.
WARNING
Disconnect from supply before opening enclosure. Keep cover
tight while circuits are alive. Conduit seals must be installed within
18" (450mm) of the enclosure.
Wiring connectors are accessed by opening the enclosure. Cover jam screw may
need to be loosened on the cover. To access electrical connectors, remove the 2
captive screws, then disconnect the ribbon cable from the display module and set the
display module aside.
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.
Pre-Installed Conduit/Stopping Plug
The PD6830 typically includes three ¾" NPT threaded conduit openings and one ¾"
NPT metal conduit plugs with 12 mm hex key fitting installed. Additional conduit
opening configurations and plugs may be available; verify quantity and sizes on
specific device labeling during installation. The pre-installed plug and its installation
are included in the hazardous area approvals for the PD6830.
The conduit/stopping plug included in a typical PD6830 has an internal 12 mm
hexagonal socket recess for removal.
WARNING
In hazardous areas, conduit and conduit/stopping plugs require the
application of non-setting (solvent free) thread sealant. It is critical
that all relevant hazardous area guidelines be followed for the
installation or replacement of conduit or plugs.
Battery Activation Pull Tab
PD6830 models with battery or battery backup power will include a battery activation
pull-tab. This tab assures the meter is not operational during shipment or storage,
and is located with the battery. Remove this tab during installation of the meter.

Mounting
The PD6830 has two slotted mounting flanges that may be used for pipe mounting or
wall mounting. Alternatively, the unit may be supported by the conduit using the
conduit holes provided.
Refer to Mounting Dimensions, page 96 for details.
WARNING
Do not attempt to loosen or remove flange bolts while the meter is
in service.
Cover Jam Screw
The cover jam screw should be properly installed once the meter has been wired and
tested in a safe environment. The cover jam screw is intended to prevent the removal
of the meter cover in a flameproof environment without the use of tools. Using a M2
hex wrench, turn the screw clockwise until the screw contacts the meter. Turn the
screw an additional ¼ to ½ turn to secure the cover. Caution: Excess torque may
damage the threads and/or wrench.
Connections
WARNINGS
 Static electricity can damage sensitive components.
 Observe safe handling precautions for static-sensitive components.
 Use proper grounding procedures/codes.
 If the meter is installed in a high voltage environment and a fault or
installation error occurs, high voltage may be present on any lead or
terminal.
To access the connectors, loosen the cover jam screw (if tightened) with an M2 hex
wrench, remove the enclosure cover and unscrew the two captive screws that fasten
the display module into the enclosure. Disconnect the ribbon cable and remove the
display module. Power and signal connections are made to a barrier terminal
connector in the base of the enclosure. Grounding connections are made to the two
ground screws provided on the base – one internal and one external. Use proper
grounding techniques for explosion-proof areas and observe all local and national
electric codes.
