Description

Models TT211 and TT711 are 2-wire temperature transmitters for 2-lead 100 ohm or 1000
ohm platinum RTD's. These transmitters are FM-approved for use in Class I, Divisions 1 & 2,
Groups A, B, C, and D hazardous locations and appear in the approval guide as IS/I/1/ABCD
and NI/I/2/ABCD. The TemptranTM converts the RTD's (resistance temperature detector's)
signal into a current proportional to the RTD's temperature. The current changes according to
the range marked on the Temptran:
4 mA at the lowest temperature of the range, rising to 20 mA at the top of the range. The
leads that supply power also carry the current signal. Request Minco Application Aid 19 for
more information.

Installation

If installing the Temptran in a hazardous location, the installer must adhere to installation
requirements as set forth by the National Electrical Code (NEC) and any other applicable codes
and standards. See pages 3 - 7 for further information on installing these transmitters in a
hazardous location.

Locate the Temptran near the RTD, in an area where the ambient temperature stays between ­25 and 85 °C (-13 and 185 °F). Mount with a #6 machine or #8 self-tapping screw.

Connect the Temptran as shown below, observing the +/- polarity of the current loop.
Maximum DC supply voltage = 35 VDC. The RTD connections have no polarity. For the RTD,
good connections are a must; a few ohms of resistance in the connection can cause an error of
several degrees.

The Temptran has been factory-calibrated for its marked temperature range or else for a
specific RTD. Do not change its zero and span adjustments.

Installation of TT211 and TT711 Temptrans

TM

in Class I, Division 1 or 2, Groups A, B, C, and D

hazardous locations.

Read these instructions thoroughly before installing transmitters.

Per Factory Mutual,

1) Installation shall be in accord with these instructions and the National Electric Code.

2) If installing in a Class I, Division 1 hazardous area, then refer to document INST. 704,
"CONTROL DOCUMENT, SYSTEM APPROVALS FOR INTRINSICALLY SAFE
TRANSMITTERS" on pages 5-7 of this manual. The Simple Apparatus, referenced in
these pages, is the RTD temperature sensor or thermocouple.

3) If installing in a Class I, Division 2 hazardous area, then the transmitters must be
mounted in a vent-free enclosure, meeting the "Electrical Utilization Enclosure
Requirements" stated below with which only the Approved equipment will be installed.
All unused openings should be sealed.

4) Tampering and replacement with non-factory components may adversely affect the safe
use of the system.

Electrical Utilization Enclosure Requirements (Required for Division 2 areas only)

1. Each of the transmitters must be mounted within an enclosure to prevent personal injury

resulting from accessibility to live parts. This enclosure must comply with the requirements
listed below. Further details of the enclosure requirements may be found in ANSI/ISA
Standards S82.01, S82.02, and S82.03.

1.1 Accessibility - The transmitters must be installed within the enclosure so that its
circuits are accessible by the use of a tool only. A part is accessible when a) the IEC

Minco Tel: [phone] • Fax: [phone] • www.minco.com • Doc. #1116290(D) 4

articulate accessibility probe applied in every possible position to the exterior or
exposed surfaces, including the bottom, or b) the IEC rigid accessibility probe applied
with a maximum force of 30 Newtons (6.75 lbs force) in every possible position to the
exterior or exposed surface, including the bottom, touches the part.

1.2 Protection from Fire - If the enclosure is non-metallic, it shall have the proper
flammability rating as detailed within ANSI/ISA Standard S82.01.

1.3 Grounding - A metallic enclosure must have a protective grounding terminal and
be marked as such. The size of the ground terminal is to be equivalent to the size of
the supply circuit conductor terminals. All accessible non-current conductive parts
must be bonded to the protective grounding terminal.

1.4 General Construction - The equipment enclosure, or parts of the enclosure,
required to be in place to comply with the requirements for protection from electric
shock, personal injury, protection from internal parts and wiring, and external cord
and cable assembly strain relief shall comply with the following tests for mechanical
strength:

a. Impact Tests - The equipment shall be held firmly against a rigid support and shall
be subjected to sets of three blows from a spring-operated impact hammer. The
hammer shall be applied to any external part that when broken is likely to expose live
parts. A window of an indicating device shall withstand an impact of 0.085 Newton­meter (0.753-pound force-inch) from a hollow steel impact sphere 50.8 mm (2 inches)
in diameter and an approximate mass of 113.4 grams (4 ounces).

b. Pressure Tests - A force of 90 Newtons (20 pounds) shall be applied from a metal
rod 12.7 mm (.50 inch) in diameter, the end of which is rounded. The force shall be
applied for one minute to any point on the overall enclosure except the bottom. The
bottom shall sustain a force of 65 Newtons (15 pounds).

c. Tip Stability Test - Equipment having a weight of 11 kilograms (24 pounds) or
more shall not tip over when placed at the center of an inclined plane that makes an
angle of 10 degrees with the horizontal and then turned to the position (with all
doors, drawers and other openable and sliding parts in the least stable position) most
likely to cause tip-over.

Minco Tel: [phone] • Fax: [phone] • www.minco.com • Doc. #1116290(D) 5

d. Sharp Edges - An accessible edge, projection, or corner of an enclosure, opening,
frame, guard, handle, or the like shall be smooth and well rounded, and shall not
cause a cut-type injury during normal use of the equipment.

Calibration

1. Connect a power supply of 24 VDC and a digital milliammeter ( 5-1/2 digit preferred ) as

shown in the figure, or use a loop calibrator instead of the DC supply and milliammeter.

NOTE: Zero and Span resistance values are printed on the transmitter's label.

2. Connect a resistance decade box with a resolution of at least .01 ohms to the input of the

transmitter. If unsure or concerned about the decade box's accuracy, measure the zero and
span resistance setting, using a known-accurate ohmmeter and record decade box settings
before connecting decade box to the transmitter.

3. Set decade box resistance to simulate the 4 mA temperature.

4. Adjust ZERO potentiometer on the transmitter until the meter reads 4 mA.

5. Set decade box resistance to simulate the 20 mA temperature.

6. Adjust SPAN potentiometer on the transmitter until the meter reads 20 mA.

7. Repeat steps 3 - 7 until no further adjustment is necessary.
