PD663 Loop-Powered Meter Instruction Manual
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. Multi-point linearization with up to 32 points and the square root function allow for conditioning of signals from non-linear transmitters without adding external components to the system.
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.

Signal Input Conditioning Function (Fnc)
The PD663 provides linear and squar root signal input conditioning functions for inputs from linear and non-linear transmitters.
Linear (Lnr)
Meters are set up at the factory for linear function using two-point linearization. Multi-point linearization with up to 32 points may be used. The linear function provides a display that is linear with respect to the input signal between each set of input points.
Square Root (sqr)
The square root function is used to linearize the signal from a differential pressure transmitter and display flow rate in engineering units.
Information Menu (info)
The Information menu is located in the Advanced features menu, to access Information menu see Advanced Features Menu, page 23.
It shows software identification number, version number, and calibration temperatures. To determine the software version of a meter:
Go to the Information menu (info) and press Enter button.
The meter will automatically scroll through the software release number and software version. The meter temperatures at the time of last internal calibration in
°C and °F are displayed for calibration troubleshooting. Pressing the Enter, Right, or Up buttons will progress the information display.
Following the information display, the meter will exit the Advanced features menu
and return to run mode.
Input Signal Filter (FIL)
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. The filter level can be set to low (LO), high (HI), or off (OFF). The higher the filter setting, the longer the averaging time and so the longer the display may take to find its final value.
The filter contains a noise filter bypass feature so that while small variations in the signal will be filtered out, large, abrupt changes to the input signal are displayed immediately.
25
PD663 Loop-Powered Meter Instruction Manual
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 meter. 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. Press and hold the Menu button for 5 seconds to enter the Advanced features
menu. Press the Up arrow button to scroll to the Internal Calibration menu (ICAL) and press Enter.
The meter displays 4.00 mA. Apply a 4.00 mA signal and press Enter. The display flashes for a moment while the meter is accepting the signal.
After the signal is accepted, the meter displays 20.00 mA. Apply a 20.00 mA signal and press Enter. The display flashes for a moment while the meter is accepting the signal.
Error Message (Err)
An error message indicates that the calibration process was not successful. After the error message is displayed, the meter will revert to input 2 calibration settings. The error message might be caused by inadvertently leaving the signal at the previous level or not maintaining a 0.40 mA minimum span. Press the Menu button to cancel the current calibration process if necessary.
