Model BD306 Dual-Input Pump Controller Instruction Manual
1. IntroductIon
The BULLDOG BD306 is a multi-purpose, easy to use digital dual-input pump controller
ideal for level, flow rate, temperature, or pressure transmitter applications. It accepts current
and voltage signals (e.g. 4-20 mA, 0-10 V). Various math functions may be applied to the
inputs including addition, difference, absolute difference, average, weighted average, multi-
plication, division, minimum, maximum, draw, ratio, and concentration. This is in addition to
the signal input conditioning functions (linear, square root, programmable exponent, or round
horizontal tank calculations).
The displays, relays, and the analog output may be assigned to input channels A or B, or
match result channel C.
Three of the front panel buttons can be custom-programmed for a specific operation.
The basic model includes an isolated 24 VDC transmitter power supply that can be used to
power the input transmitters or other devices. An additional isolated 24 VDC power supply is
included with the 4-20 mA output option.
A fully loaded BD306 meter has the following: four SPDT relays, 4-20 mA output, and two 24
VDC power supplies. The BD306 capabilities may be enhanced by adding the following exter-
nal expansion modules: four SPST relays - creating an eight-relay dual-input pump controller,
two digital I/O modules with four inputs and four outputs each, and serial communication
adapters for use with BULLDOG Pro or Modbus RTU.

NOTE:
Testing was conducted on BD300 meters installed through the covers of
grounded metal enclosures with cable shields grounded at the point of
entry representing installations designed to optimize EMC performance.
CAUTION: R ead complete
instructions prior to installation
and operation of the meter.
WARNING: Risk of
electric shock or
personal injury.
WARNING!
Hazardous voltages exist within enclosure.
Installation and service should be performed only by
trained service personnel.

6. InStallatIon
There is no need to remove the meter from its case to complete the installation, wiring, and set-
up of the meter for most applications.
Instructions are provided for setting up a 12/24 VDC powered meter to operate from 12 VDC
and for changing the transmitter power supply to output 5 or 10 VDC instead of 24 VDC, see
page 14.
6.1. 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.

6.2. 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).
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.
Note: See Figure 23 on page 101 for 1/8 DIN Panel Cutout Template
