INSTALLATION

There is no need to remove the meter from its case to complete the installation, wiring, and setup of the meter.

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.

Panel Mounting

• Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm

x 45 mm). Refer to Mounting Dimensions, page 48 for more details.

• Clearance: allow at least 4" (102 mm) behind the panel for wiring.

• Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).

Recommended minimum panel thickness to maintain Type 4X rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.

• Remove the two mounting brackets provided with the meter (back-off

the two screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the bracket toward the front of the case and remove).

• Insert meter into the panel cutout.

• Install mounting brackets and tighten the screws against the panel.

To achieve a proper seal, tighten the mounting bracket screws evenly until meter is snug to the panel along its short side. DO NOT OVER TIGHTEN, as the rear of the panel may be damaged.

Connections

All connections are made to removable screw terminal connectors located at the rear of the meter. You must use copper wire with 60°C or 60/75°C insulation.

Observe all safety regulations. Electrical wiring should be performed in accordance with all appli-

cable national, state, and local codes to prevent damage to the meter and ensure personnel safety.

Connector Labeling

The label on each meter shows the location of all connectors for the particular model. As an example Figure 2 illustrates the connector layout for meters equipped with relays and 4-20 mA transmitter. Other models have different connector arrangements.

Serial Communication

The PD644 can be connected directly to an RS-485 data bus of up to 32 nodes. For systems consisting of more than 32 nodes RS-485 repeaters are necessary. Serial communication wiring connections to the PD644 are made via the three position screw terminal connector labeled RS-485. Please refer to standard EIA-485 for complete specifications for balanced digital multi-point communications. The use of shielded twisted pair cable is recommended to protect the data signals from electrical interference. For long wire runs it is good practice to terminate the bus at both ends with a resistor connected between D+ and D- that matches the characteristic impedance of the cable. A typical value for termination resistors is 120 .

Figure 5. RS-485 Data Bus Connections

For non-multiplexed serial communications with RS-232 data communications equipment such as a personal computer, an RS-232 to RS-485 converter such as the Precision Digital PDA7485 is required. If using a PDA7485, connect the PD644 according to the PDA7485 wiring diagram for a two wire RS-485 application.

Switching Inductive Loads

The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent disrupting the microprocessor’s operation. The suppressors also prolong the life of the relay contacts. Suppression can be obtained with resistor-capacitor (RC) networks assembled by the user or purchased as complete assemblies. Refer to the following circuits for RC network assembly and installation:

Figure 1. AC and DC Loads Protection

Choose R and C as follows:

R: 0.5 to 1  for each volt across the contacts C: 0.5 to 1 µF for each amp through closed contacts

Notes:

1. Inductive relay rating is 1/14 HP (50 W) at 115/230 VAC

2. Use capacitors rated for 250 VAC.

3. RC networks may affect load release time of solenoid loads. Check to confirm proper operation.

4. Install the RC network at the meter's relay screw terminals. An RC network may also be installed across the load. Experiment for best results.

Use a diode with a reverse breakdown voltage two to three times the circuit voltage and forward current at least as large as the load current.

Figure 2. Low Voltage DC Loads Protection

RC Networks Available from Precision Digital

RC networks are available from Precision Digital and should be applied to each relay contact switching an inductive load. Part number: PDX6901.

Relays are de-rated to 1/14th HP (50 watts) with an inductive load.

Off Time Delay

If the signal crosses the set point, the On time delay timer starts and the relay trips when the time delay has elapsed. If the signal drops below the set point (high alarm) before the time delay has elapsed, the On time delay timer resets and the relay does not change state. The same principle applies to the Off time delay.

*The LED is not affected by Time Delay when “Automatic or Manual” reset mode is selected. Rather the LED follows the set and reset points.

Programming the Meter (prog)

It is very important to read the following information, before proceeding to program the meter:

• There is no need to recalibrate the meter when first received from

the factory.

• The meter is factory calibrated prior to shipment. The calibration equipment used at the factory is certified to NIST standards.

• Simply connect the power and signal to the proper terminals, and turn the power on. No calibration needed! (when the meter is first received from the factory).

The Program menu contains the Calibrate and the Scale menus. The input may be calibrated or scaled to any display within the range of

the meter.

Noise Filter (fltr)

Most applications do not require changing this parameter. It is intended to help attain a steady display with an unsteady (noisy) input signal.

The field selectable noise filter averages any minor or quick changes in the input signal and displays the reading with greater stability.

Increasing the filter value will help stabilize the display, however this will slow down the display response to changes in the input signal.

The filter level may be set anywhere from 2 to 199. Setting filter value to zero disables filter function, and bypass setting

becomes irrelevant.

Noise Filter Bypass (byps)

The meter can be programmed to filter small input changes, but allow larger input changes to be displayed immediately, by setting the bypass value accordingly.

If the input signal goes beyond the bypass value, it will be displayed immediately with no averaging done on it.

The noise filter bypass value may be set anywhere from 0.2 to 99.9. It corresponds to percentage of full scale.

Increasing the bypass value may slow down the display response to changes in the input signal.

Javelin D ● Model PD644 Voltmeter Instruction Manual

Serial Communications (serl)

The meter is equipped with serial communications capability as a standard feature using PDC Serial Communication Protocol. The Modbus RTU Protocol is optional and may be purchased at any time.

To communicate with a computer or other data communications equipment which lacks an RS-485 interface, an RS-232 to RS-485 adapter such as the Precision Digital PDA7485 is required. Please refer to Or- dering Information on page 3 for details.
