✱

List of functions

Affix one of the enclosed lists of functions to the cover flap.

6.2 Prior to mounting

De-pressurize the system befor e mounting the JUMO dTRANS p02 pressure transmitter!

The installation site should be readily accessible, as close as possible to the measurement point, and largely free from vibration. The permissible ambient temperature limits must be observed (note possible radiant heat).

The JUMO dTRANS p02 pressure transmitter may be mounted above or below the pressure tapping.

The measurement arrangements below serve as an example and can be altered according to the requirements of the measurement task.

6 Mounting

Operating position

The normal operating position of the JUMO dTRANS p02 pressure transmitter is vertically upright.

Depending on the conditions of the measurement site, the pressure transmitter can also be mounted in a different orientation. In accordance with the required operating position, the LC D can be rotated in 90° steps, see

➩

"Rotating the instrument", page 42.

6.3 Mounting by the pressure connection

6.4 Mounting by the housing

There are M 20x1. 5 threads on either side of the housing. One of the threads is used to screw in the cable gland (optionally right or left). The other thread can be used to mount the pressure transmitter.

6 Mounting

6.5 Pressure connection

Seals Seals to EN 837 or DIN 16 258 may be used.

Tightening torque

Check for tightness

200 Nm max. The correct tightening torque depends on the size, materi al and shape of the

seal that is used, as well as on the pressure connection of the pressure transmitter.

After establishing the pressure connection, it must be checked for tightness.

7.6 Electrical connection in the hazardous (Ex) area

General The appropriate regulations must be observed when making the electrical

connection; inside the area with an explosion hazard this is, in particular:

- the regulations concerning electrical equipment in areas with an explosion hazard (Elex V)

- the regulation for the installation of electrical equipment in areas with an explosion hazard EN 60 079-14:1997 (VDE 0165)

- EC Type Examination Certificate

The HART® modem must not be used in the hazardous area! The supply must be intrinsically safe and must not exceed the

following maximum values:

: 30 V DC Ii: 100 mA Pi: 750 mW

The connection of the HART® communicator or the HART modem is optional.

For fault-free communication, the signal circuit must be loaded with a minimum burden of 250 the burden is in most cases already integrated.

9.1 The level concept

Two levels In order to make the operation of the pressure transmitter simple and transpar-

ant, the functions of the JUMO dTRANS p02 have been divided into two levels.

Both levels can be accessed from the keypad of the transmitter.

The keypad can be found underneath the cover fl ap of the pressure transmitter.

➩

"Open cover flap", page 14.

As an alternative to operation from the keys, all the measured values and parameters can be easi ly displayed and / or set up us ing the setup program. Th e setup program is available on request, at extra cost

➩

"Setup program", page 7.

Display level In normal operation, the instrument is in the display level.

Parameter level

The display options are: pressure, measurement, output current, sensor temperature or peak-reading pointer. Step thr ough with the or keys.

After applying the supply voltage, and after the end of the self-test, the instrument is in the display level. The display that was most recently selected will be shown (for new instruments ex-works, this is “Pressure with unit”).

At this level, the para meters that can be checked or altered include the following: measurement start, measurement end, zero, dimensional unit, damping and output current in a fault situation.

Damping To dampen an unsteady display caused by rapidly changing pressures, the

Minimum and maximum pressures are saved. Both values can be individually display e d and deleted.

If the damping is set to 0 .0sec, minimum and maximum pressures will not be saved.

➩

"Detailed explanations", page 38.

If the damping is 0.0sec, or after a reset of the display, “- - - - -” will be shown.

The pressure can be indicated directly in bar or in another pressure unit.

The output current (in mA) that is available at the start (or end) of the measurement can be set within the range +3.85 to +21.5mA. At the same time, the pressure applied is saved as measurement start or end.

time constant for the display, T

At a damping of 0.0sec, the pressure transmitter will not save the minimum and maximum pressures, i.e. the peak-reading pointer function is switched off.

, can be adjusted from 0.0 to 100.0sec.

Measurement start, blind setting

Measurement span, blind setting

The measurement start can be set in % of the nominal pressure range. The nominal measurement range is given on the nameplate.

➩

"Nameplate", page 8 .

Example:

The pressure transmitter has a nominal range of 0 to 25bar, but the output signal needs to be proportional in the range 5 to 20bar.

The necessary setting for the measurement start is derived as follows: Nominal range: 0—25bar Meas. start required: 5bar, corresponding to 20% of the nominal range Setting: 20%

The measurement span can be set in % of the nominal measurement range.

Example 1:

The pressure transmitter has a nominal measurement range from 0 to 25bar, but the output signal needs to be proportional in the range 5 to 20bar.

The necessary setting for the measurement span is derived as follows: Nominal range: 0— 25bar Range required: 5—20bar => required span: 15bar Span required: 15bar, corresponding to 60% of the nominal range Setting: 60%

9 Adjustment options

Example 2:

Nominal range: 0— 600mbar Range required: -300 to +300mbar Measurement start: -50% Span: 100%

Zero adjustment

Current generator

Output current in fault situation

When a zero adjustment is made, the transmitter display is set to 0.000. The preset measurement start remains unaffected.

Setting the measurement start:

➩

"Output current, measurement start and end", page 38.

This function is inhibited for absolute-pressure transmitters.

➩

"Nameplate", page 8.

If the “current generator” function is selected, an adjustable constant current is present at the transmitter output.

There is no time-out for this function; the current can remain indefinitely.

This function can only be ended by pressing the key. It is not possible in multidrop mode.

➩

"Connection of a HART® communicator", page 20. In this case,

a constant current of 4mA is present at the output.

In order to indicate measurement errors in the event of over /underrange, or other errors, (e.g. for a connected PLC), the pressure transmitter gives out either 3.85mA or 21.5mA.

➩

"Output signal and display", page 23.

Keys inhibited To prevent an unauthorized modification of parameters, some or all of the

parameters can be inhibited.

To remove an inhibit (LA, L0, LS), the key must be pressed for longer than 5 seconds in the display “Output current in fault sit- uation” (P9).

The inhibit “LALL” can only be set or deleted in the setup program.

Characteristic The characteristic of the output current can be selected as:

❏

Lin: linear (proportional to pressure).

❏

SLin: linear up to the starting point, then square root

(proportional to flow-through),

❏

SoFF: square-root (proportional to flow), but switched off up to

the starting point.

The starting point of the square-root characteristic can be adjusted between 5.0 and 15.0% of the output current.
