| 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. 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.  PD662 Input Connections with Backlight  PD662 Input Connections without Backlight  PD662 Heater Connections 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.   PD662 Menu Progression DIMENSIONS  Except where noted all specifications apply to operation at +25°C. General Display: 0.6" (15.24 mm) LCD, 3½+ digits; -1999 to 2999 Display Update Rate: 2 Updates/Second Over-Range: Display Flashes 2999 Under-Range: Display Flashes -1999 Programming Method: 4 Front Panel Pushbuttons Noise Filter: Programmable HI, LOW, or OFF Recalibration: Recalibration is recommended at least every 12 months. Max/Min Display: Max/Min readings reached by the process are stored until reset by the user or until power to the meter is turned off. Password: Programmable password restricts modification of programmed settings. Non-Volatile Memory: All programmed settings are stored in non-volatile memory for a minimum of ten years if power is lost. Normal Mode Rejection: 64 dB at 50/60 Hz Operating Temperature: -40 to 85°C (-55 to 85°C with heater option) Storage Temperature: -40 to 85°C Relative Humidity: 0 to 90% non-condensing Connections: Removable screw terminals accept 12 to 22 AWG Tightening Torque: Screw terminal connectors: 4.5 lb-in (0.5 Nm) Enclosure: Impact-resistant polyester plastic, body color gray, clear cover with blue faceplate; NEMA 4X, IP66; ½" conduit hole provided at base Weight: 9.3 oz (264 g) Overall Dimensions: 3.15" x 4.33" x 2.76" (80 mm x 110 mm x 70 mm) (W x H x D) Warranty: 3 years parts & labor Input Input: 4-20 mA Accuracy: ±1 count Temperature Drift: 50 PPM/°C from -40 to 85°C ambient Decimal Point: User selectable decimal point Minimum Span: Input 1 & Input 2: 0.40 mA Maximum Voltage Drop: 1.7 VDC @ 20 mA; 4.9 VDC @ 20 mA with backlight option. Equivalent Resistance: 85 Ω @ 20 mA without backlight; 245 Ω @ 20 mA with backlight Loop-Powered Backlight Option: Factory installed only with field wiring option. Powered directly from the 4-20 mA loop, no batteries required. The display brightness will increase as the input signal current increases. Heater Option Power: 24 VDC, 11 W Maximum. The heater unit only draws power when required to keep the meter at approximately -20°C. Ambient Temperature Range: Allows PD662 to operate at -55°C to 85°C. Temperature Cutoff: Internal 104°C thermal cutoff for over temperature protection. |
