Warranty
Flowline warrants to the original purchaser of its products that such products will be
free from defects in material and workmanship under normal use and service in
accordance with instructions furnished by Flowline for a period, which is equal to the
shorter of one year from the date of purchase of such products or two years from the
date of manufacture of such products. Flowline's obligation under this warranty is
solely and exclusively limited to the repair or replacement, at Flowline's option, of the
products or components, which Flowline's examination determines to its satisfaction to
be defective in material or workmanship within the warranty period. Flowline must be
notified pursuant to the instructions below of any claim under this warranty within thirty
(30) days of any claimed lack of conformity of the product. Any product repaired or
replaced under this warranty will be warranted only for the remainder of the original
warranty period.
Returns
Products cannot be returned to Flowline without Flowline's prior authorization. To
return a product that is thought to be defective, go to www.flowline.com, and submit a
customer return (MRA) request form and follow the instructions therein. All warranty
and non-warranty product returns to Flowline must be shipped prepaid and insured.
Flowline will not be responsible for any products lost or damaged in shipment.
Limitations
This warranty does not apply to products which: 1) are beyond the warranty period or
are products for which the original purchaser does not follow the warranty procedures
outlined above; 2) have been subjected to electrical, mechanical or chemical damage
due to improper, accidental or negligent use; 3) have been modified or altered; 4)
anyone other than service personnel authorized by Flowline have attempted to repair;
5) have been involved in accidents or natural disasters; or 6) are damaged during
return shipment to Flowline. Flowline reserves the right to unilaterally waive this
warranty and dispose of any product returned to Flowline where: 1) there is evidence
of a potentially hazardous material present with the product; or 2) the product has
remained unclaimed at Flowline for more than 30 days after Flowline has dutifully
requested disposition. This warranty contains the sole express warranty made by
Flowline in connection with its products. ALL IMPLIED WARRANTIES, INCLUDING
WITHOUT LIMITATION, THE WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE, ARE EXPRESSLY DISCLAIMED. The remedies of

The LD30 Series Pressure Transmitters convert a single positive pressure into a
standard 4-20 mA output signal. The LD30 Series can be used to accurately measure
compatible gases and liquids; full scale accuracy is 0.25%. Designed for industrial
environments with a NEMA 4X (IP66) housing, this transmitter resists most effects of
shock and vibration. This Quick Start includes everything you’ll need to get the
DeltaSpan up and running. For complete information, please refer to DeltaSpan
documentation located at www.flowline.com.

Installation
First, select a location. The DeltaSpan should be located within a temperature
range of 0 and 175°F (-18 to 79°C). Distance from the receiver is limited only by total
loop resistance. While the tubing or piping supplying pressure to the unit can be
practically any length, remember that long lengths will increase response time slightly.
Next, position the DeltaSpan. Although the transmitter is not position sensitive,
standard models are factory calibrated in a position with the pressure connection
downward. The DeltaSpan functions at greatest accuracy in this position.
Create a pressure connection. Use a small amount of plumber’s tape or other
suitable sealants to prevent leaks. Be sure the pressure passage inside the port is not
blocked.
Finally, check your Electrical Connections. The maximum length of wire connecting
the transmitter and receiver is a function of wire size and receiver resistance. Wiring
should not contribute more than 10% of the receiver resistance to total loop resistance.
For runs exceeding 1000 feet, choose receivers with higher resistance to minimize the
size and cost of connecting leads. Where wiring length is under 100 feet, wire as small
as 22 AWG can be used.
Electrical connections to the pressure transmitters are made to the terminal block
located inside the housing. Remove the screws and lift off the cover. Wire as shown in
the diagram below. When using cable version of General Purpose Housing with Cable,
black wire is negative (-) and red wire is positive (+).
Current (4-20 mA) Output Operation
An external power supply delivering 13-30 VDC with minimum current capability of 40
mA DC (per transmitter) is required to power the control loop. The Current Output
diagram (above) shows the connection of the power supply, transmitter and receiver.
The range of appropriate receiver load resistance (RL) for the DC power supply
voltage available is expressed by the formula: RLMax = Vps-13
20 mA DC
Shielded cable should always be used for control loop wiring.
Maximum Loop Resistance is 1300ohms @ 30VDC.
Maintenance
After final installation of the pressure transmitter and its companion receiver, no
routine maintenance is required. A periodic check of system calibration is suggested.
The LD30 transmitters are not field repairable and should be returned if repair is
needed.
Troubleshooting
If you face any issues not addressed in this Quick Start, please refer to the DeltaSpan
Manual located on Flowline website at www.flowline.com.
Where personal safety or significant property damage can occur due to a spill,
the installation must have a redundant backup safety system installed.
Welcome to the DeltaSpan Quick Start
The DeltaSpan Quick Start is meant to show some of the more common setup solutions
to getting the DeltaSpan up and running quickly. If you run into an issue that is not
addressed here or wish to install or set up with a non-standard configuration, please
address the DeltaSpan Manual or refer to the Flowline website at www.flowline.com.
CAUTION
Do not exceed specified supply voltage ratings. Permanent damage
not covered by warranty will result. This device is not designed for
120 or 240 volt AC operation. Use only on 13 to 30 VDC.
