INTRODUCTION
The ProtEX-Lite PD663 is a rugged, NEMA 4X loop-powered meter in an
explosion-proof enclosure ideal for applications where a simple, inexpensive
display is required in a hazardous area. The PD663 is scaled using four push
buttons and can be done without applying an actual calibration signal.
Programming may also be done through the explosion-proof enclosure with
optional magnetic reed switches and a magnet key. The PD663’s display will
read up to 2999; we call this 3½+ digits! The loop-powered backlighting option
lets you see the display under any lighting condition and is powered completely
from the 4-20 mA loop. This means there is no need for additional wiring and
never any batteries to change.
The PD663 is housed in a rugged, explosion-proof, cast aluminum, NEMA 4X
enclosure and is provided with two threaded conduit holes and integrated pipe or
wall mounting holes.

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 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

PD663 Loop-Powered Meter Instruction Manual

INSTALLATION
For Installation in USA: The PD663 must be installed in accordance with the
National Electrical Code (NEC) NFPA 70.
For Installation in Canada: Install in accordance with applicable local and
national regulations (e.g. NEC). The PD663 must be installed in accordance with
the Canadian Electrical Code CSA 22.1. All input circuits must be derived from a
CSA approved Class 2 source.
For European Community: The PD663 must be installed in accordance with the
ATEX directive 94/9/EC and the product certificate Sira 10ATEX116X.
All pushbuttons and wiring connectors are accessed by opening the enclosure.
To access electrical connectors, remove the 2 captive screws and remove the
meter assembly. Pushbuttons may also be accessed using the magnet assembly
if reed switches are installed.
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 Plug
The PD663 is supplied with one pre-installed optional conduit plug for
installations that do not require the use of both conduit entries. The conduit plug
includes an internal hexagonal socket recess for removal. The pre-installed plug
and installation are included in all hazardous area approvals of the PD663.
WARNING: Disconnect from supply before opening enclosure. Keep cover
tight while circuits are alive. Conduit seals must be installed within 18" (450
mm) of the enclosure.
WARNING: Installations of the supplied conduit plug require the application of
non-setting (solvent free) thread sealant. If the pre-installed conduit plug is
removed or replaced all relevant hazardous area guidelines must be followed
for its installation or replacement conduit.

PD663 Loop-Powered Meter Instruction Manual
13
Mounting
The PD663 has two mounting holes that may be used for a 1.5” pipe mounting or
wall mounting. Alternatively, the unit may be supported by the conduit using the
conduit holes provided.
It can also be pipe mounted by using the PDA6845 pipe mount kit for 2" pipe.
Refer to Mounting Dimensions, page 32 for details on wall or panel space
requirements
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 1/4 to 1/2 turn to secure the cover. Caution:
Excess torque may damage the threads and/or wrench.
Connections
To access the connectors, remove the enclosure cover and unscrew the two
captive stainless steel screws. Remove the meter assembly from the enclosure.
Signal connections are made to a three-terminal removable connector on the
back of the meter assembly. Grounding connections are made to the two ground
screws provided on the base – one internal and one external.
WARNING: Do not attempt to loosen or remove flange bolts while the meter
is in service.
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.

4-20 mA Input Connections & Wiring Diagrams
Signal input connections are made to a three-terminal connector labeled S+|S-|X
for models without a backlight and S+|S-|B- for models with a backlight. The
enclosure also provides one internal and one external earth grounding screw.
The 4-20 mA input with no backlight has a maximum voltage drop of 1.7 V and is
wired as shown in Figure 2. The loop-powered backlight configuration requires a
total maximum voltage drop of 4.7 V. The backlight is recommended for dim
lighting conditions and is enabled when wired as shown in Figure 3. The
enclosure also provides one internal and one external earth grounding screw.

Programming the Meter
It is very important to read the following information, before proceeding to
program the meter:
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.
Use the Scale (SCL) menu to enter scale parameters without applying a live
signal.
Alternatively, use the Calibrate (CAL) menu to apply a signal from a calibrator or a
4-20 mA transmitter to calibrate the meter.
Inputs may be calibrated or scaled to any display within the range of the meter.
Additional parameters, not needed for most applications, are viewed and
programmed with the Advanced features menu, see Advanced Features Menu,
page 24.
Minimum Input Span
The minimum input span is the minimum difference between input 1 and input 2
signals required to complete the calibration or scaling of the meter. The minimum
span is 0.40 mA.
If the minimum span is not maintained, the meter reverts to input 2, allowing the
appropriate input signals to be applied.
