INTRODUCTION

The DP6070 meter boasts specifications and functionality that clearly makes it one of the most advanced temperature meters available. Its dual-line 6-character display, function keys, and optional expansion modules are only a few of the features you will find on the DP6070.

A fully loaded DP6070 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 DP6070 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.

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 DP6070 an excellent addition to any system.

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 14. 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. 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.

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.

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

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

59). 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.

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:

Alarm # HI or LO

Front Panel LEDs

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

LED Status LED Status

1 Alarm 1 5 Alarm 5 2 Alarm 2 6 Alarm 6 3 Alarm 3 7 Alarm 7 4 Alarm 4 8 Alarm 8

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 visual-only 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):

Latching and Non-Latching Relay Operation

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

Relay terminology for following tables Terminology Relay Condition

On Alarm (Tripped) Off Normal (Reset)

Ack Acknowledged

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

Warning!

In latching relay mode, latched relays will reset

(unlatch) when power is cycled.

Non-Latching Relay (Auto)

Automatic reset only

Condition LED Relay

Normal Off Off Alarm On On Ack (No effect) On On Normal Off Off

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)

Automatic + manual reset at any time

Condition LED Relay

Normal Off Off Alarm On On Normal Off Off Next Alarm On On Ack On Off Normal Off Off

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)

Manual reset any time

Condition LED Relay

Normal Off Off Alarm On On

Ack Off Off 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.

DP6070 Temperature Meter Instruction Manual

Latching Relay (Lt-Clr)

Manual reset only after alarm condition has cleared

Condition LED Relay

Normal Off Off Alarm On On Ack (No effect) On On Normal On On

Ack Off Off 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 27).

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

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 22.

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

page 39.

Page 70

DP6070 Temperature Meter Instruction Manual

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.

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 the rounding selected. This setting affects the last two digits, regardless of decimal point position. On the DP6070 the valid selections are 1, 2, 5, 10 only.

Page 71

DP6070 Temperature Meter Instruction Manual

Modbus RTU Serial Communications (serial)

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

To communicate with a computer or other data terminal equipment, an RS-232, RS-485, or USB adapter (DPA8008) option is required; see

Ordering Information on page 9 for details.

Do not connect any equipment other than OMEGA’s

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.

The DP6070 can also be connected to another DP6070 with a special DPA1200 cable, allowing the user to copy all the settings from one meter to another, using the

Copy function.

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.
