Manual Series 2.4
QUICK BENCH TEST (PRESSURE INPUT):
Connect Sensor as shown below, then apply Power. When properly connected figures will be shown on
the LCD display. Test operation of the TFT32 by applying pressure to the sensor or 4-20mA input. The
TFT32 will now display level in inches or cm.
CONNECTIONS:
POWER INPUT: The standard model requires DC power input between 15 to 24VDC with current
consumption of 120mA maximum. Power GND must be connected to a good “earth” ground for surge
protection.
RS485 NETWORK: Connections from the 485 network (other TFT32’s and the PC computer) are:
Data - (D*), Data + (D) and signal/shield ground (S.G.)
IMPORTANT NOTE: To comply with CSA/NRTL standards, power input and relay connection wires
must have a water tight fitting conduit entry to the instrument enclosure.

KEYPAD SYSTEM
The TFT32 has a simple 2-key calibration system. Operating and calibration modes are shown on the 4
digit display. The keys are used to calibrate the TFT32, and to view operating mode and functions. If the
keys are not used for 10 minutes, the TFT32 will automatically go to NORMAL MODE. Except in
OUTPUT SIMULATION mode, the Relay and RS485 serial output are not affected by use of the keys
until your calibration is stored.

Pressing a corresponding key will move to the next box in the direction shown. Numeric values are
changed by pressing and holding the Ç or È keys.
At the bottom of Menu is a YES? prompt. To store the calibration values permanently (even through
power failure), press the Ç key. If the È key is pressed from the YES? prompt no changes will be
stored and the system will return to NORMAL mode.

Note: the greater the range between LO and HI levels for this procedure, the better the accuracy of your
calibration. (eg: LO at 10% and HI at 90% will produce a more accurate calibration than LO at 40% and
HI at 60%).
Note: If only one value is changed during a calibration then the second calibration point remains the
unchanged value from the last calibration (ie. You can perform a single point calibration to improve
upon the previous calibration).
Note: Sensor input difference between HI and LO must be greater than 2mA.

Examples of “Bench Calibration” Calculations
Example 1 - PS11 sensor
- Specific gravity of tank contents is 1.5
- Sensor is mounted at a level of 6 inches
- Calibration units (CALU) are in inches
LO = 6.0
[20mA Level] = 138.6 inches
HI = [20mA Level]
+ LO = 138.6 + 6.0 = 98.4
Specific Gravity 1.5
Example 2 - PS11 sensor
- Specific gravity of tank contents is 1.0
- Sensor is mounted at a level of 15
- Calibration units (CALU) are in cm
LO = 15.0
[20mA Level] = 352.0 cm

ENCLOSURE INSTALLATION
Locate the enclosure within 10,000 ft (3,000 m) of the pressure sensor. It can be wall mounted with four
mounting screws (supplied) or panel mounted with Option PM Panel Mounting Kit from Greyline
Instruments. Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due
to overheating and condensation. Seal conduit entries to prevent moisture from entering enclosure.

3. Replace Cover
An additional conduit hole can be cut in the end of the enclosure if
required. Use a hole saw or Greenlee-type hole cutter to cut the required
holes.
Note:
1 This non-metallic enclosure does not automatically provide grounding between conduit connections.
Grounding must be provided as part of the installation. Ground in accordance with the requirements
of the National Electrical Code. System grounding is provided by connecting grounding wires from
all conduit entries to the steel mounting plate or another point which provides continuity.

TFT32 COMMUNICATION PROTOCOL
Greyline TFS Tank Farm Supervisor software manages communications with TFT32 Transmitters
automatically. The following Communication Protocol information is supplied for programmers who are
not using the Greyline TFS Tank Farm Supervisor program. Programmers can create their own drivers
to address TFT32 Transmitters through other software programs on PC computers or PLC’s.
The TFT32 uses an ASCII format command/response protocol. The TFT transmits an answer only when
polled with a valid command and address. The Host computer always initiates the command/response
sequence.
