Model BD300 Analog Input Process Meter Instruction Manual

DISCLAIMER:

1. IntroductIon

The BULLDOG BD300 is a multi-purpose, easy to use digital process meter ideal for level, flow rate, temperature, or pressure transmitter applications. It accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Three of the front panel buttons can be custom-programmed for a specific operation. The analog input can be scaled to display the process in two different scales; for example the main display could indicate level in feet and the second display could indicate the volume in gallons.

The basic model includes an isolated 24 VDC transmitter power supply that can be used to power the input transmitter or other devices. An additional isolated 24 VDC power supply is included with the 4-20 mA output option. A digital input is standard. A fully loaded BD300 meter has the following: four SPDT relays, 4-20 mA output, and two 24 VDC power supplies. The BD300 capabilities may be enhanced by adding the following external expansion modules: four SPST relays (creating an eight-relay process 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 process control applications, such as pump alternation control. The 4-20 mA isolated output, Modbus RTU serial

communications, and digital I/O options make the BD300 an excellent addition to any

system.

Model BD300 Analog Input Process Meter Instruction Manual

5.12. 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:

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 contracts

Notes:

Use capacitors rated for 250 VAC

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

operation.

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.

The relay and the digital I/O expansion modules BDXM & BDIO are connected to the meter using a CAT5 cable provided with each module. The two RJ45 connectors on the expansion

modules are identical and interchangeable; they are used to connect additional modules to the system.

Note: The jumper located between the RJ45 connectors of the BDIO must be removed on the second digital I/O module in order for the system to recognize it as module #2.

WARNING!

Do not connect ar disconnect the expansion modules with the power on!

More detailed instructions are provided each optional expansion module.

5.18. 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 61).

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.

6.8. Relay Operation Details

6.8.1. 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, level, pressure or flow alarms, control applications such as simple on/off pump control, and pump alternation control for up to 8 pumps. 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. Pump Alternation Control for up to 8 Pumps

6.8.2. 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

Alarm

Set Point Reset Point

6.8.3. Fail-Safe Operation

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

Fail-Safe

Selection

Non-Alarm State Alarm State

Power Failure

NO NC NO NC

Off Open Closed Closed Open Relays go to non-alarm state On Closed Open Open Closed Relays go to alarm state

Note: NO = Normally Open, NC = Normally Closed. This refers to the condition of the relay contacts when the power to the meter is off.

Model BD300 Analog Input Process Meter Instruction Manual

6.8.4. Front Panel LEDs

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

Return to Table of Contents

LED STATUS

1 Alarm 1 2 Alarm 2 3 Alarm 3 4 Alarm 4

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

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 rest:

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 19).

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

6.8.10. Pump Alternation Control Applications (ALtErn)

For pump control applications where two or more similar pumps are used to control the level of a tank

or a well, it is desirable to have all the pumps operate alternately. This prevents excessive wear and

overheating of one pump over the lack of use of the other pumps.

Up to 8 relays can be set up to alternate every time an on/off pump cycle is completed. The set points can be programmed, so that the first pump on is the first pump off.

6.8.10.1. Application #1: Pump Alternation Using Relays 1 & 2

1. Relays 1 and 2 are set up for pump alternation.

2. Relays 3 and 4 are set up for low and high alarm indication.

Set and Reset Point Programming

Relay Set Point Reset Point Function

1 30.000 10.000 Controls Pump #1

2 35.000 5.000 Controls Pump #2

3 4.000 9.000 Controls Low Alarm

4 40.000 29.000 Controls High Alarm

Return to Table of Contents

Model BD300 Analog Input Process Meter Instruction Manual

Pump Alternation Operation

1. Pump #1 turns on when level reaches 30.000, when level drops below 10.000, pump #1 turns off.

2. The next time level reaches 30.000, pump #2 turns on, when level drops below

10.000, pump #2 turns off.

3. If the level doesn’t reach 35.000, pump #1 and pump #2 will be operating alternately.

4. If pump #1 cannot keep the level below 35.000, pump #2 will turn on at 35.000,

then as the level drops to 10.000, #1 turns off, pump #2 is still running and shuts

off below 5.000.

5. Notice that with the set and reset points of pump #2 outside the range of pump

#1, the first pump on is the first pump to go off. This is true for up to 8 alternating

pumps, if setup accordingly.

6. Relay #3 will go into alarm if the level drops below 4.000 and relay #4 will go into alarm if the level exceeds 40.000.

7. Adding the 4 external relays, expansion module allows using the 4 SPDT internal relays for pump alternation and the 4 SPST external relays for high, high-high, low, and low-low alarm indication.

6.8.10.2. Application #2: Pump Alternation Using Relays 3 & 4

1. Relays 1 and 2 are set up for pump alternation.

2. Relays 3 and 4 are set up for low and high alarm indication.

The following graphics provide a visual representation of a typical pump alternation application with high and low alarm monitoring:

1. Relay #4 turns the main pump on at 6000 gallons and turns it off at 1000 gallons.

2. With the Pump Alternation feature activated, the next time the level reaches 6000

gallons, relay #3 transfers and starts the backup pump.

3. If the backup pump is not able to keep up, and the level reaches 7000 gallons, relay #4 transfers and starts the main pump as well.

Relays 1 & 2 are configured to energize (their front panel LEDs are off) when SW1 and SW2

switches (above) are closed. If the contacts to these digital inputs are opened, the corresponding

front panel LEDs flash indicating this condition. The processes being controlled by the interlock relay will stop, and will re-start only after the interlock relay is reactivated by the digital inputs

6.13.2. Noise 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.

6.13.3. Noise Filter 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.

The tare function zero’s out the display. In the case of scale weight, tare is used to eliminate

container weight and provide net weight readings.

There are two functions; Capture Tare and Reset Tare.

When the capture tare function is used the display reading is offset by the displayed amount to make the displayed value zero. This modified display value is the net value. The originally dis-

played value without the tare offset is the gross value. Both may be chosen as a display option. Reset tare removes the display offset of the net value, and the gross and net values become the same until a new capture tare is entered.

6.18. Internal Source Calibration (ICAL)

The meter is factory calibrated priot to shipment

to read in milliamps and volts depending on the

input selection. The calibration equipment is

certified to NIST standards.

The use of calibrated signal sources is necessary to calibrate the internal source of the meter.

The meter’s internal source is what allows the user to scale the meter without applying a signal.

Check calibration of the meter at least every 12 months. Each input must be recalibrated sepa-

rately.

Notes:

If meter is in operation and it is indended to accept only one input type (e.g. 4-20 mA), recalibration of other input is not necessary.

Allow the meter to warm up for at least 15 minutes before performing the internal

source calibration procedure.

The meter is capable of accepting current (0-20 mA, 4-20 mA) and voltage signals (0-5 V, 1-5 V, 0-10 V, ± 10 V) and displaying these signals in engineering units from -99999 to 999999 (

e.g.

a 4-20 mA signal could be displayed as -50.000 to 50.000).

The dual-line display can be customized by the user to operate in such a way as to satisfy a

specific application. Typically the main display is used for the process variable; while the second display is used for engineering units, custom legend, or set point indication.

The analog input can be scaled to display the process in two different scales; for example: with d-SCAL enabled, the main display could indicate level in feet and the second display could indicate the volume in gallons.

Additionally the meter can be set up to display the analog input on the main display and the ModBUS input on the second display. The relays and analog output can be programmed to operate from the ModBUS PV input.

8. troubleShootIng

The rugged design and the user-friendly interface of the meter should make it unusual for the installer or operator to refer to this section of the manual. However, due to the many features and functions of the meter, it’s possible that the setup of the meter does not agree with what an

operator expects to see.

If the meter is not working as expected, refer to the
