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.

5.2. Panel Mounting Instructions

 Prepare a standard ⅛ DIN panel cutout – 3.622” x 1.772” (92 mm x 45 mm).

Refer to Figure 1 below, for more details.  Clearance: allow at least 6.0” (152 mm) behind the panel for wiring.  Panel thickness: 0.04” - 0.25” (1.0 mm - 6.4 mm).  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.

To configure the meter for 12 VDC power.

Remove all the connectors.

Unscrew the back cover.

Slide the back cover about 1 inch.

5.4. Transmitter Supply Voltage Selection (P+, P-)

All meters, including models equipped with the 12/24 VDC power option, are shipped from the factory configured to provided 24 VDC power for the transmitter or sensor.

If the transmitter requires 5 or 10 VDC excitation, the internal jumper J4 must be configured

accordingly.

To access the voltage selection jumper:

Remove all the wiring connectors.

Unscrew the back cover.

Slide out the back cover by about 1 inch.

Configure the J4 jumper, located behind the input signal connector,

for the desired excitation voltage shown.

5.5. Connections

All connections are made to removable screw terminal connectors located at the rear of the meter.

Use copper wire with 60 °C or 60/75 °C insulation for all line voltage

connections. Observe all safety regulations. Electrical writing should be performed in accordance with all applicable national, state, and local codes to prevent damage to the meter and ensure personnel safety.

WARNING!

and the meter.

5.7. Power Connections

Power connections are made to a two-terminal connector labeled POWER on Figure 7 on page

19. The meter will operate regardless of DC polarity connection. The + and – symbols are only

a suggested wiring convention.

Return to Table of Contents

Model BD300 Analog Input Process Meter Instruction Manual

5.8. Signal Connections

Signal connections are made to a six-terminal connector labeled SIGNAL on Figure 7. The COM (common) terminal is the return for the 4-20 mA and the ±10 V input signals.

5.9. Current and Voltage Connections

The following figures show examples of current and voltage connections.

There are no switches or jumpers to set up for current and voltage inputs. Setup and programming is performed through the front panel buttons.

The current input is protected against current overload by a resettable fuse. The display may or may not show a fault condition depending on the nature of the overload.

The fuse limits the current to a safe level when it detects a fault condition, and automatically resets itself when the fault condition is removed.

5.10. ModBUS RTU Serial Communications

Serial communications connection is made to an RJ45 connector labeled M-LINK on Figure 7.

For interfacing to the BULLDOG, use the BD232SA for RS-232, the BD422SA for RS-485, or the

e.g.

BDUSBSA for the USB. The same port is used for interfacing with all expansion modules ( external relays, digital I/O).

Using the BDCCC meter copy cable for meter-to-meter interfacing for cloning purposes (

i.e.

copying settings from one meter to other meters).

5.11. Relay Connections

Relay connections are made to two six-terminal connectors labeled RELAY1 – RELAY 4 on Figure

7. 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.

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.

Model BD300 Analog Input Process Meter Instruction Manual

5.13. RC Networks Available from Blue Ribbon Corp

RC networks are available from Blue Ribbon Corp and should be applied to each relay contact

switching an inductive load. Part number: BD6901.

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

5.14. F4 Digital Input Connections

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

5.15. 4-20 mA Output Connections

Connections for the 4-20 mA transmitter output are made to the connector terminals labeled MA OUT. The 4-20 mA output may be powered internally or from an external power supply.

5.16. Analog Output Transmitter Power Supply

The internal 24 VDC power supply powering the analog output may be used to power other devices, if the analog output is not used. The I+ terminal is the +24 V and the R terminal is the return.

5.17. External Relays & Digital I/O Connections

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.

There are no jumpers to set for the meter input selection. Setup and programming is done

through the front panel buttons. After power and input signal connections have been completed and verified, apply power to the meter.
