Introduction

The PROVU® PD7000 temperature meter accepts a direct temperature input from a wide range of temperature measurement devices (type J, K, T, E, R, S, B, N, and C thermocouples and 100 or 1000 Ω platinum, 10 Ω copper, 120 Ω nickel RTDs). It displays the measured temperature in either degrees Fahrenheit or degrees Celsius on a dual-line, 6-digit display whose superluminous LED digits make it easily readable in smoke, dust, fog, and, with the optional SunBright® display, even direct sunlight. The PD7000 includes automatic cold junction compensation for thermocouples and the ability to average up to ten (10) RTD sensors.

A fully loaded PD7000 meter has the following: four SPDT relays, 4-20 mA output, and one 24 VDC power supply to power the 4-20 mA output. The PD7000 capabilities may be enhanced by adding the following external expansion modules: four SPST relays (creating an eight-relay temperature meter), two digital I/O modules with four inputs and four outputs each, and USB, RS-232 or RS-485 communication adapters. A digital input is standard.

The eight relays can be used for alarm indication or temperature control applications. The 4-20 mA isolated output, Modbus RTU serial communications, and digital I/O options make the PD7000 an excellent addition to any system.

TC input. The RANGE selector switch is used to select 100-ohm platinum or 10-ohm copper RTD. The 1000-ohm

platinum RTD input uses the same setting as the 100-ohm RTD. The input type is selected using the Setup menu. The selected thermocouple input must correspond to the thermocouple sensor and wire type used. The meter accepts two, three, or four-wire RTDs. The three-wire RTD connection has built-in lead wire

compensation. Lead wire compensation for two-wire RTDs can be applied using the Adjust menu. See the Advanced Features Menu on page 34. The four-wire RTD connection is similar to the three-wire. One of the leads of a four-wire RTD is not connected, and may be clipped off.

The three-wire connection provides sufficient lead wire compensation to obtain accurate readings even with long leads.

To obtain the average temperature from 2 to 10 RTD sensors, connect all the sensors in parallel and select the number of sensors in the RTD Total (rtdtot) menu. See the Advanced Features Menu on page 34.

Figure 11. Average Temperature RTD Input Connections

Modbus RTU Serial Communications

Serial communications connection is made to an RJ45 connector labeled M-LINK on Figure 5. For interfacing to the PROVU®, use the PDA1232 for RS-232 or the PDA1485 for RS-485. The same port is used for interfacing with all expansion modules (i.e. external relays, digital I/O).

Relay Connections

Relay connections are made to two six-terminal connectors labeled RELAY1 – RELAY4 on Figure 5. Each relay’s C terminal is common only to the normally open (NO) and normally closed (NC) contacts of the corresponding relay. The relays’ C terminals should not be confused with the COM (common) terminal of the INPUT SIGNAL connector.

Figure 12. Relay Connections

PROVU PD7000 Temperature Meter Instruction Manual

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.

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 13. AC and DC Loads Protection

Choose R and C as follows: R: 0.5 to 1 Ω for each volt across the contacts C: 0.5 to 1 µF for each amp through closed contacts

Notes:

1. Use capacitors rated for 250 VAC.

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

3. 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.

Figure 14. 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.

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

F4 Digital Input Connections

A digital input, F4, is standard on the meter. This digital input connected with a normally open closure across F4 and COM, or with an active low signal applied to F4.

Note: The jumper located between the RJ45 connectors of the PDA1044 must be removed on the second

digital I/O module in order for the system to recognize it as module #2.

PROVU PD7000 Temperature Meter Instruction Manual

Interlock Relay Feature

As the name implies, the interlock relay feature reassigns one, or more, alarm/control relays for use as interlock relay(s). Interlock contact(s) are wired to digital input(s) and trigger the interlock relay. This feature is enabled by configuring the relay, and relative digital input(s) (see page 31). In one example, dry interlock contacts are connected in series to one digital input which will be used to force on (energize) the assigned interlock power relay when all interlock contacts are closed (safe). The interlock relay front panel LED flashes when locked out. The interlock relay would be wired in-series with the load (N/O contact). See below.

The following graphic shows relay 1 action setup; relay 2-8 are set up in a similar fashion.

Programming Set and Reset Points

High alarm indication: program set point above reset point. Low alarm indication: program set point below reset point. The deadband is determined by the difference between set

and reset points. Minimum deadband is one display count. If the set and reset points are programmed with the same value, the relay will reset one count below the set point.

Note: Changes are not saved until the reset point has been accepted.

Setting Fail-Safe Operation

In fail-safe mode of operation, the relay coil is energized when the process variable is within safe limits and the relay coil is de-energized when the alarm condition exists. The fail-safe operation is set independently for each relay. Select on to enable or select off to disable fail- safe operation.

Programming Time Delay

The On and Off time delays may be programmed for each relay between 0 and 999.9 seconds. The relays will transfer only after the condition has been maintained for the corresponding time delay.

The On time delay is associated with the set point. The Off time delay is associated with the reset point.

Relay Action for Loss of Input (Input Break)

Each relay may be programmed to go to one of the following conditions when the meter detects the loss of the input signal:

1. Turn On (Go to alarm condition)

2. Turn Off (Go to non-alarm condition)

3. Ignore (Processed as an upscale condition)

PROVU PD7000 Temperature Meter Instruction Manual

High Alarm Operation (Set > Reset)

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. To detect a new alarm condition, the signal must go below the set point, and then go above it.

Low Alarm Operation (Set < Reset)

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. For relay to turn back “on”, signal must go above set point and then go below it.

High Alarm with Fail-Safe Operation (Set > Reset)

Note: Relay coil is energized in non-alarm condi-

tion. In case of power failure, relay will go to alarm state.

Low Alarm with Fail-Safe Operation (Set < Reset)

Relay Operation Details

Overview

The relay capabilities of the meter expand its usefulness beyond simple indication to provide users with alarm and control functions. These capabilities include front panel alarm status LEDs as well as either 2 or 4 optional internal relays and/or 4 external relays expansion module. Typical applications include high or low temperature alarms, control applications such as simple on/off temperature control. There are four basic ways the relays can be used:

1. High or Low Alarms with Latching or Non-Latching Relays

2. Simple On/Off Control with 100% Adjustable Deadband

3. Sampling (Based on Time)

4. Relay Alternation Control

Relays Auto Initialization

When power is applied to the meter, the front panel LEDs and alarm relays will reflect the state of the input to the meter. The following table indicates how the alarm LEDs and relays will react on power-up based on the set and reset points:

Fail-Safe Operation

The following table indicates how the relays behave based on the fail-safe selection for each relay:

Note: NO = Normally Open,

NC = Normally Closed. This refers to the condition of the relay contacts when the power to the meter is off.

Front Panel LEDs

The LEDs on the front panel provide status indication for the following:

The meter is supplied with four alarm points that include front panel LEDs to indicate alarm conditions. This standard feature is particularly useful for alarm applications that require visualonly indication. The LEDs are controlled by the set and reset points programmed by the user. When the display reaches a set point for a high or low alarm, the corresponding alarm LED will turn on. When the display returns to the reset point the LED will go off. The front panel LEDs respond differently for latching and non-latching relays.

For non-latching relays, the LED is always off during normal condition and always on during alarm condition, regardless of the state of the relay (e.g. Relay acknowledged after alarm condition).

For latching relays, the alarm LEDs reflect the status of the relays, regardless of the alarm condition. The following tables illustrate how the alarm LEDs function in relation to the relays and the acknowledge button (Default: F3 key assigned to ACK).

PROVU PD7000 Temperature Meter Instruction Manual

Warning!

In latching relay mode, latched relays will reset (unlatch) when power is cycled.

Latching and Non-Latching Relay Operation

The relays can be set up for latching (manual reset) or non-latching (automatic reset) operation.

The On and Off terminology does not refer to the status of the relay’s coil, which depends on the fail-safe mode selected.

Non-Latching Relay (Auto)

In this application, the meter is set up for automatic reset (non-latching relay). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm finally goes away, the relay automatically resets and the LED also goes off.

Non-Latching Relay (A-nman)

In this application, the meter is set up for automatic and manual reset at any time (non-latching relay). The LED and the relay automatically reset when the meter returns to the normal condition. The next time an alarm occurs, the operator acknowledges the alarm manually while the alarm condition still exists. This causes the relay to reset, but the LED stays on until the meter returns to the normal condition.

Latching Relay (LatcH)

In this application, the meter is set up for manual reset at any time. Acknowledging the alarm even if the alarm condition is still present resets the relay and turns off the LED.

Latching Relay (Lt-Clr)

In this application, the meter is set up for manual reset only after the signal passes the reset point (alarm condition has cleared). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm is acknowledged after it returns to the normal state, the LED and the relay go off. Notice that the LED remains on, even after the meter returns to the normal condition. This is because, for latching relays, the alarm LED reflects the status of the relay, regardless of the alarm condition.

Acknowledging Relays

There are two ways to acknowledge relays programmed for manual reset:

1. Via the programmable front panel function keys F1-F3 (Default: F3 assigned to ACK).

2. Remotely via a normally open pushbutton wired across one of the digital inputs and the +5 V terminals on the digital I/O modules, or using the F4 digital input, which is triggered with a contact closure to COM, or with an active low signal (see page 14).

When the ACK button or the assigned digital input is closed, all relays programmed for manual reset are acknowledged.

Figure 21. Acknowledge Relays w/Function Key or Digital Input

Setting Up the Interlock Relay (Force On) Feature

Relays 1-4 can be set up as interlock relays. To set up the relays for the interlock feature:

1. Access the Setup – Relay – Action menu and set the action to off.

2. In the Advanced features – User menu program any of the digital inputs to Force On any of the internal relays (1-4).

3. Connect a switch or dry contact between the +5V terminal and the corresponding digital input (dI-1 to dI-4) terminal.

Interlock Relay Operation

Relays 1 & 2 are energized when SW1 & SW2 switches are closed and the front panel LEDs are off. If

the contact to the digital input is opened, the corresponding front panel LED flashes indicating this condition. The processes being controlled by the interlock relay stop and will re-start only after the interlock relay is activated by the digital inputs.

Scaling the 4-20 mA Analog Output (Aout)

The 4-20 mA analog output can be scaled to provide a 4-20 mA signal for any display range selected. No equipment is needed to scale the analog output; simply program the display values to the

corresponding mA output signal. The Analog Output menu is used to program the 4-20 mA output based on display values.

Note: During the analog output scaling, the display value is always indicated with a decimal point

regardless of the decimal point selection for the temperature display.

Reset Menu (reset)

The Reset menu is used to reset the maximum or minimum reading (peak or valley) reached by the process; both may be reset at the same time by selecting “reset high & low” (rst HL).

Control Menu (Contrl)

The Control menu is used to control the 4-20 mA analog output and the relays manually, ignoring the input. Each relay and analog output can be programmed independently for manual control. Selecting automatic control sets all relays and analog output for automatic operation.

Recalibration of the Meter (t CAL)

The Calibration (t CAL) menu is used to recalibrate the thermocouple and RTD inputs.

Allow at least 30 minutes warm-up time before performing recalibration procedure to ensure specified accuracy.

Recommended Calibration Points

To recalibrate the meter, it is recommended to use the Fahrenheit scale; this will give a greater degree of accuracy to the calibration. The scale can be changed to the Celsius scale after calibration is completed. The meter will display temperature accurately in any scale. The following table shows the recommended low and high calibration points for all types.

Recalibration Procedure

1. Connect signal to the meter using the appropriate wire (e.g. type J thermocouple wire to recalibrate type J input), see page 12.

2. Set up the meter to accept the selected input (e.g. type J T/C), see page 23.

3. Set up the meter to display temperature in degrees Fahrenheit.

4. Apply signal corresponding to input 1 (32°F) and program the display to read 32.0.

5. Apply signal corresponding to input 2 (1184°F for type J) and program the display accordingly.

6. After the meter accepts input 2, the display returns to reading mode. This completes the recalibration procedure for the selected input.

PROVU PD7000 Temperature Meter Instruction Manual

Warning!

Do not connect any equipment other than Precision Digital’s expansion modules, cables, or meters to the RJ45 M-LINK connector. Otherwise damage will occur to the equipment and the meter.

Noise Filter (filter)

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 determines the length of time over which the signal is averaged. The filter level can be set between 2 and 199. The higher the filter level, the longer the averaging time and so the longer it takes the display to settle to its final value. Setting the filter level to zero disables the filter function.

Noise Filter Bypass (bypass)

The noise filter bypass changes the behavior of the meter so that small variations in the signal are filtered out but large abrupt changes in the input signal are displayed immediately. The bypass value determines the minimum amount of signal change to be displayed immediately. All signal changes smaller than the bypass value are filtered or averaged by the meter. The noise filter bypass may be set between 0.1 and

99.9% of full scale.

Rounding Feature (round)

The rounding feature is used to give the user a steadier display with fluctuating signals. Rounding is used in addition to the filter function.

Rounding causes the display to round to the nearest value according to the rounding selected. This setting affects the last two digits, regardless of decimal point position. On this ProVu model, the valid settings are 1, 2, 5, and 10 (only).

Modbus RTU Serial Communications (serial)

The meter is equipped with serial communications capability as a standard feature using the Modbus RTU Serial Communication Protocol.

The meter may be connected to a PC for initial configuration via the onboard micro USB connection. For ongoing digital communications with a computer or other data terminal equipment, an RS-232, or RS-485 option is required; see Ordering Information on page 5 for details.

Note: More detailed instructions are provided with each optional serial communications adapter.

Note: Refer to the ProVu® Modbus Register Tables located at www.predig.com for details.

When using more than one meter in a multi-drop mode, each meter must be have its own unique Slave ID or meter address. The ID or address may be programmed between 1 and 247. The transmit delay may be set between 0 and 199 ms. The parity can be set to even, odd, or none with 1 or 2 stop bits.

PROVU PD7000 Temperature Meter Instruction Manual

Select Menu (SElect)

The Select menu is used to program the analog output parameters. There are no other selections for this model.

Analog Output Programming (AoutPr)

The Analog Output Programming menu is used to program the behavior of the 4-20 mA output. The following parameters and functions are programmed in this menu:

1. Source: Source for generating the 4-20 mA output (e.g. PV - temperature)

2. Overrange: Analog output value with display in overrange condition

3. Underrange: Analog output value with display in underrange condition

4. Break: Analog output value when input break is detected

5. Max: Maximum analog output value allowed regardless of input

6. Min: Minimum analog output value allowed regardless of input

7. Calibrate: Calibrate the internal 4-20 mA source reference used to scale the 4-20 mA output

Analog Output Source

The source for generating the 4-20 mA output may be assigned to the process variable, maximum or minimum value reached by the process, one of the set points, or the Modbus PV input.

Analog Output Calibration

To perform the analog output calibration, it is recommended to use a milliamp meter with a resolution of at least 0.1 µA to measure the output current. The values saved internally during this procedure are used for scaling the 4-20 mA output in the Setup menu.
