QUICKSTART
The PD662 is designed to be easily wired into your current
loop and quickly programmed.
Wiring
The two wire power/signal connection is made on the back
of the PD662 on the three position removable terminal
block. Follow instructions printed on the unit for two wire
loop-powered connections with or without backlight.
INTRODUCTION
The PD662 Hatchet NEMA 4X loop-powered meter is
perfect for applications where a simple, inexpensive display
is required and AC power is not available. That’s because
the PD662 derives all its power from the 4-20 mA loop. The
PD662 is scaled using four push buttons and can be done
without applying an actual calibration signal. The PD662’s
display will read up to 2,999; 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 PD662 Hatchet
is housed in rugged NEMA 4X enclosure and is provided with
one ½" conduit hole. The PD662 is available with an optional
24 VDC powered heater that allows the PD662 to operate in
temperatures as low as -55°C.

Programming
The PD662 Hatchet comes calibrated and scaled at the factory
to display a 4.00 to 20.00 mA signal on startup. To change
the scaling, follow along using the 4 button interface.
