The Proper Installation & Maintenance of TX801RTD.

MOUNTING.

(1) Mount in a clean environment in an electrical cabinet on 35mm, symetrical, mounting rail.

(2)

(3)

(4)

Do not subject to vibration or excess temperature or humidity variations.

Avoid mounting in cabinets with power control equipment.

To maintain compliance with the EMC Directives the TX801RTD must be mounted in a fully enclosed steel cabinet. The cabinet must be properly earthed, with appropriate input / output entry points, filtering, and cabling.

WIRING.

(3)

(7)

RTD'S.

(1)

(2)

(3)

A readily accessible disconnect device and overcurrent device must be incorporated in the the power supply wiring.

All cables should be good quality overall screened INSTRUMENTATION CABLE with the screen earthed at one end only.

Signal cables should be laid a minimum distance of 300mm from any power cables.

For 2 wire current loops Austral Standard Cables B5102ES is recommended. For three wire transmitters and RTD's

Austral Standard Cables B5103ES is recommended.

It is recommended that you do not ground current loops and use power supplies with ungrounded outputs.

Lightning arrestors should be used when there is a danger from this source.

Refer to diagrams for connection information.

Avoid locating the RTD where it will be in a direct flame.

Locate it where the average temperature will be measured. It should be representative of the mass.

Immerse the RTD far enough so that the measuring point is entirely in the temperature to be measured; nine to ten times the diameter of the protection tube is recommended. Heat that is conducted away from the measuring point causes an error in reading.

COMMISSIONING.

(1) Once all the above conditions have been carried out and the wiring checked apply power to the TX801RTD loop and allow five minutes for it to stabilize.

(2) Due to differences in cable resistance in the RTD legs or errors within the RTD itself a small Zero error may occur (usually less than 0.5C). To remove this error use a calibration standard RTD at the same immersion depth and adjust the Zero trimpot in the top of the TX801RTD enclosure with a small screwdriver, until the two levels agree. (Clockwise to increase the output reading and anti-clockwise to decrease the output reading.)

MAINTENANCE.

(1) Check RTD's in place - with a calibration RTD at the same immersion depth.

(2)

(3)

(4)

Do it regularly - at least once every 6 months.

Replace defective protection tubes - even if they look good they may not be air or gas tight.

Check cables entering the RTD sensor head.

Quality Assurance Programme.

The modern technology and strict procedures of the ISO9001 Quality Assurance Programme applied during design, development, production and final inspection grant long term reliability of the instrument.

TX801RTD Input Programming.

Always set OUTPUT range first, then INPUT range.

If the input range is not listed in the programming table, use the following formulae to work out the Zero and Span DIP switch settings for gain.

deg C Span Gain = 1200 deg C High - deg C Low deg F Spain Gain = 2400 deg F High - deg F Low

deg C Zero Gain = deg C Low

5 deg F Zero Gain = deg F Low

10

If Zero is:

D I

G

P a i

S n w i

V t a l c h u e

N o .

1/ Positive, put S5-1 OFF. 2/ Negative, put S5-1 ON.

So if a gain value of 28 is required, put DIP switch No's 3, 4, 5 OFF, (ie, gains

1 2 4 8 1 6 3 2 of 4 + 8 + 16 = 28) and all the other DIP switches ON.

1 2 3 4 5 6

DIP switches and trimpots are accessed by removing the small rectangular lid on the top of the TX801RTD enclosure

Note: (a)

(b)

Enter the Zero or Span gain value into the appropriate Zero or Span DIP switch.

If the ZERO GAIN exceeds 63, then the input range must be factory calibrated.

TX801RTD Input Range Programming Table.

Notes: 1/

Switch status 1 = ON, 0 = OFF, X = DON'T CARE.

Input ranges with '*' beside them require more adjustment by the Span trimpot.
