This document contains the recommended basic procedures installing and calibrating the Hawkeye Industries Goshawk Level Transmitter
for use on a Redtail or Roadside Gauge Head. For more comprehensive instructions, please refer to the Goshawk Operation and Trou-

Quick Start Installation Instructions
Goshawk Level Transmitter
► 1 Goshawk Level Transmitter
► 2 1/4-20 UNC x 3/4 Hex Cap screw (included)
Installation on Redtail
► 1 Redtail Gauge Head with
► 1 Redtail Electronic Cover Plate installed
Installation on Roadside
► 1 Roadside Gauge Head with:
► 1 Roadside Electronic Cover Plate installed
If the electronic cover plate is not already installed, remove the standard
cover plate from the Indicator (Open) side of the gauge head, and replace
with the appropriate Electronic Cover Plate for your gauge head.
Turn the indicator cable spool IN THE EMPTYING DIRECTION (CLOCK-
WISE) until the the indicator is in the empty position (top of gauge board).
Immobilize the spool. (cover omitted for clarity)

Turn the Transition Coupler on the Goshawk Transmitter IN THE EMPTY-
ING DIRECTION (COUNTER-CLOCKWISE) until it stops. DO NOT OVER
TURN, AS DAMAGE WILL OCCUR. Then turn the Transition Coupler on
the Goshawk Transmitter IN THE FILLING DIRECTION (CLOCKWISE)
Aligning the tangs on the transmitter with the cover plate bolt holes and
fasten with the 1/4 NC Hex Cap Screws. Ensure the transition coupler
mates with the gauge head axle without binding by turning the reel a few
times before tightly securing the transmitter to the cover plate.

Loop Power Connections
After removing the transmitter cover, the PCB will be visible.
Run the conductors from the conduit port into the transmitter body, and
connect the positive lead from your PLC or Process Meter to the (+) termi-
nal, and the negative lead to the (-).
A Ground or Shield termination (S) is also provided for convenience.
Remove the transmitter cover to expose the PCB and wiring connections.
REDTAIL SYSTEM ROADSIDE SYSTEM
Power up the PLC or loop calibrator. Adjust the R20 (Zero) trimmer (high-
lighted) to achieve a 4 mA output. Turn the trimmer clockwise to increase
the output value, counterclockwise to decrease. If the zero does not in-
crease above 3.5 mA, this is indicative of a damaged potentiometer, see
Section 7.1 Operating and Troubleshooting Guide.
If not already in place, put the gauging system into the TANK EMPTY PO-
SITION, noting the direction of travel of the highlighted items. If the tank
is in-service, see Section 3.3.3 and 4.2 in the Operating and Trou-
REDTAIL SYSTEM ROADSIDE SYSTEM
Put the gauging system into the TANK FULL POSITION, noting the direc-
tion of travel of the highlighted items.
Adjust the R19 (Span) trimmer (highlighted) to achieve a 20 mA output.
Turn the trimmer clockwise to increase the output value, counterclockwise
to decrease. If the span remains below 20 mA, or remains above 20 mA,
this is indicative of problems with the span sensitivity. Refer to Section
4.1 in the Operating and Troubleshooting Guide.
Reinstall the cover, and the transmitter is ready for service.
Please refer to the Operations and Troubleshooting Guide for more de-
tailed notes on installation, calibration and non-standard configurations.
