1. INTRODUCTION

1.1 COMMON INTRODUCTION 1000TR is a new CE-approved series of transmitters from Elmacron AB. In the series, there are instruments for pH, Redox%, Redox mV and temperature measurement. 1000TR is easy to program, calibrate and use. The layout on the instrument is clear; a large display with four LED-segments, diode indication for the menu and four large function keys. All settings are made through the function keys on the front panel. When connecting a Pt100-sensor to 1000TR-TEMP the display shows the actual temperature in the solution measured. 1000TR-TEMP is provided with an isolated output 0/4 - 20 mA, proportional to the temperature, for connection to, for example, a computer, printer or other recording equipment. When measuring is interrupted, the output stays frozen at the last measured value

1.2 PARTS & ACCESSORIES 1000TR is delivered without connection cables and electrodes.

2. INSTALLATION

2.1 CASING The casing is made of die-cast polystyrol with a transparent front cover that is closed with a snaplock. The connection terminals are located in a separate partition at the lower part of the transmitter. At the bottom of the instrument there are four cable glands ( two 15,2 and two 18,6 ) for the electrical connections. The protection class is IP65.

2.2 MOUNTING The instrument is designed for wall mounting. Be sure that the instrument is mounted at a non-vibrating place. 1000TR is mounted vertically with two fastening screws (∅ 7) through the mounting brackets on the instrument.

2.3 ELECTRICAL INSTALLATION It is recommended that each instrument is provided with a separate power switch. The electrode coax cable must be protected by a screen and may not be installed near power cables. Avoid extension of cables.

The connection terminals are located in a separate space at the lower part of the transmitter.

2.3.2 Connection of a temperature probe ( RTD Pt100 ) The Pt100-senor is connected to terminal 6, 7, 8 and 9 ( 1A, 1B, 1C and 1D )

2.3.2.1 Connection of 4-wire Pt100 2.3.2.2 Connection of 2-wire Pt100

A pre-set calibration has to be done when installing a new Pt100-sensor ( see chapter 5.2 ).

2.3.3 Connection of a recorder Connect the recorder to terminal 10 ( REC + ) and terminal 11 ( REC - ).

2.4 CHECK THE CONNECTIONS Before the power supply is turned on; check that the connections are mechanical and electrical correct.

3. FUNCTIONS

3.1 COMMON FUNCTIONS All settings are made through the function keys on the front panel. The keys + and – are accelerating in three steps when they are kept pressed. Chosen function is indicated by a green diode in the menu, at alarm a red diode is activated at the same time as the diode at the actual function activates. When pressing M you step down in the menu. When calibration or setting mode is entered the output signal stays "frozen" at the latest value, until = is pressed.

4. PARAMETER SETTINGS

4.1 DEFAULT SETTINGS When delivered, 1000TR have the following default settings: Output 0 - 20 mA

4.2 PARAMETER SETTINGS All settings has to be confirmed with = to be saved. To leave the setting mode without saving the settings: press M. Before starting up the transmitter the following parameters has to be set: Temperature compensation and output range. Turn the power on.

4.2.1 Set the output 1. Interrupt the measuring by pressing + and – at the same time until the measuring is

interrupted and the diode at OUTPUT is activated. 2. Choose between 0 - 20 and 4 - 20 mA with +. 3. Press = to confirm. The diode at MEASURE is activated and the display shows Hold. 4. Press = to start the measurement.

4.3 CALIBRATION OF THE Pt100-SENSOR A pre-calibration according to 5.2 has to be performed when a new Pt100 sensor is installed.

4.4 OPERATION Measuring is started when the power supply is turned on. After an interruption off the measuring it can be restarted by pressing = when the MEASURE diode is activated. The display shows the actual temperature in the solution measured at the same time as the corresponding mA-signal is sent to the output. During the operation, the diode at MEASURE is activated.

5. MAINTENANCE

5.1 HARDWARE CHECK A check of the hardware is necessary only if you suspect that there is something wrong with your transmitter.

1. Disconnect the power supply. 2. Short-circuit the electrode input. 3. Connect a mA-meter to the REC-output. 4. Press M and connect the power supply, keep M pressed during 5 seconds until the four

upper diodes are activated. 5. The transmitter performs a self-test according to table 5.1.1 5.1.1 Hardware check

CH01 Test of LED on display All 4 LED-segments are activated

CH02 Test of function keys Press the keys one by one and the corresponding sign is shown on the display

CH03 Test of output signal Press =. 20.00 is shown on the display at the same time as the corresponding signal is sent to the output. Press =. 04.00 is shown on the display at the same time as the corresponding signal is sent to the output. Press =

CH04 test of diodes All the menu diodes are activated

The version number is shown, then the instrument starts to measure.

5.2 PRE-CALIBRATION The transmitter is always pre-calibrated when delivered. Pre-calibration is only necessary when the instrument has been shut of for a longer period or when a new Pt100-sensor is connected.

1. Check the Pt100-sensors response time*. ( See specification from the supplier ). 2. Turn the off the power supply. 3. Connect the Pt100-sensor. Immerse the Pt100-sensor in icy water ( 0 °C ). 4. Press – and turn on the power supply. Keep the key pressed until the display shows

CAL1.CAL1.CAL1.CAL1. (10 seconds). Wait according to step 1. 5. Press = to continue. 6. On the display: P0.°°°°C during 5 s. NOTE! Do not toch the sensor during the 5 seconds! 7. The display showsCal2. Immerse the Pt100-sensor in hot water ( 100 °C ). Wait

according to step 1. 8. Press = to continue.

9. On the display: P1.°°°°C during 5 s. NOTE! Do not touch the sensor during the 5 seconds! 10. The instrument returns to measuring mode, the measuring starts automatically. *The response time from the Pt100-sensor can be from 5 seconds up to 20 minutes.

5.3 RESET OF DEFAULT SETTINGS The settings are reset according to chapter 4.1.

1. Turn off the power supply. 2. Press + and turn on the power supply. Keep the key pressed until the display shows ClrOClrOClrOClrO

(10 seconds). The four lower diodes are activated. 3. Press = to continue. The display shows the version number and then the measuring starts up

6. TROUBLE SHOOTING CODE INDICATES PROBABLE CAUSE CORRECTION E-01 The temperature in the

measured solution is to low. The temperature in the measured solution is below 0 °C Broken Pt100-sensor Damage at the connections of the Pt100-sensor

Correct the temperature Replace the sensor Check the connections

E-02 The temperature in the measured solution is too high.

The temperature in the measured solution is above 100 °C Broken Pt100-sensor Damage at the connections of the Pt100-sensor
