Input signal: 0 … X Volt

In the angle-type plug the 4 male contacts are directly connected 1:1 with the socket.
The logger connection is on contact 1 (signal+) and contact 2 (signal-).
If your transmitter assignments for the ‘signal+’ and ‘signal-‘ are different, please do not forget to adjust the male contacts of your angle-type plug accordingly:
To do so open the angle-type plug and remove the red and the blue wires entering the housing from the coupling of the angletype plug.
Connect wires with the respective contacts, representing signal + (blue wire) and signal – (red wire) at your transmitter.

Input signal: 0 … 20 mA

In the angle-type plug the male contacts 1, 2 and 4 are directly connected 1:1 with the socket. The T-Logg (Rs = ~70 Ohm) is located between the male contact 3 (-) and the jack 3 (+).

If the ‘signal’-line in your transmitter is not assigned to contact 3, please do not forget to adjust the logger-angle-type plug and the external angle-type plug accordingly:
To do so open the logger-angletype plug and exchange the black wire of contact 3 against the wire of the contact representing the ‘signal’ in your transmitter. Then exchange and/or rewire the two contacts in the angle-type plug of your connecting cable.

Input signal: 4 … 20 mA

In the angle-type plug the male contacts 1, 3 and 4 are directly connected 1:1 with the socket. The T-Logg (Rs = ~70 Ohm) is located between the male contact 2 (-) and the jack 2 (+).

If the ‘signal/GND’-line in your transmitter is not assigned to contact 2, please do not forget to adjust the logger-angle-type plug and the external angle-type plug accordingly:
To do so open the logger-angletype plug and exchange the red wire of contact 2 against the wire of the contact representing the ‘signal/GND’ in your transmitter. Then exchange and/or rewire the two contacts in the angle-type plug of your connecting cable.

How to change the assignment of the angle-type plug

Dismantle the plug by pulling the adapter insert out of the case, using a screwdriver at the lateral groove.
Change the assignment according to the notes at the respective input signal.
Latch coupling inserts in the cover. You have a choice between 4 different orientations – each of them spaced 90°.
Please make sure to adjust the connecting cable, if the assignment of the angle-type plug has been changed for the types 4-20mA and 0-20mA.
Put on an angle-type plug and connect plugs using the long screw delivered. (Do not forget seals).

Advice regarding the state of the logger upon delivery
Upon its delivery, the logger is in a kind of ‘sleeping state’:
The display does not show anything, the power consumption is at its minimum.
The T-Logg wakes up as a communication link with software has been established. After that the message
Stop appears on display. The logger is ready for operation now.

Configuration of the display range
The display range, position of the decimal point and the display unit can be set by the software MINI SOFT (or GSOFT 40K) in the register ―Settings‖.
Furthermore, it can be used to read out sensor information and to program the alarm points of the logger.

Operating mode display
The T-Logg is equipped with a 10 mm LCD.
The main purpose of the LCD is to indicate the measured value. Depending on the operating mode of the logger, other messages will be displayed as well.

STOP
The T-Logg is stopped‘. No data are recorded. The logger memory is empty.
The logger is reset and can be restarted.

HALT:
The T-Logg has been ‗halted‘. The stored data can be read.
The logger memory is not empty.

DISPLAY OF MEASURED VALUE:
The small arrow is flashing The logger is active.
Measurements are carried out at certain intervals. The measured value will be stored.

START DELAY:
The logger is active, but no data are recorded.
As soon as the start delay time has expired, the logger will start recording under the starting conditions programmed before.

START ALARM:
The logger is active, but no data are recorded. Recording will start as soon as the measured value is within the min. and max. alarm limits.

BATTERY:

Changing display BAT / Value:
The battery of the T-Logg is getting discharged soon.
Replace the battery briefly. Even so, data logging is still active.

Constant display BAT:

The Logger battery is empty now and data logging has been stopped.
Replace the battery immediately.

ALARM LOW:
The measured value is below the min. alarm limit.

ALARM HIGH:
The measured value has exceeded the max. alarm limit.

ERROR 1:
The input signal has exceeded the measuring range of the logger.

ERROR 2:
The input signal has fallen below the measuring range of the logger.

ERROR 3:
The max. display range (9999) of the logger is exceeded.

ERROR 4:
The min. display range (-1999) of the logger is under-run.

ERROR 7:

The T-Logg has detected a system fault.
Remedy:
Remove the battery and wait about 30 minutes. Then insert the battery again.
If the error message is displayed furthermore, please send the logger to the manufacturer to repair.

Battery service life and recording time

Measuring cycle: 2 sec. 10 sec. 15 min. 5 hours
Recording time: 8.9 hours 44 hours 166 days Approx. 9 years
Battery service life: — Approx. 1 year Approx. 3 years —

Please note!

Short measuring cycles as well as frequently measuring data transfer result in a reduction of the battery service life!
Even if the T-Logg is connected, power consumption is increased. So it‘s important to connect the logger with the USB interface of the PC only as long as necessary!

Battery replacement

Notice:
As soon as BAT appears at display, the battery needs to be replaced. If battery voltage power decreases continuously, data logging will be stopped (compare with operating status’ ‗HALT‘).
Available stored data remains in the memory and does not get lost. It‘s possible to read the measuring data after replacement of the battery!

Replacement:

Remove the 4 screws at the front of the logger with a small screwdriver and remove the cover from the housing.
Take out the PCB and deposit it carefully beside the housing with the LCD face down. Take care not to damage the gasket.
Push out the button cell carefully from the socket (see the picture at the top on the right).
Insert the new button cell (type CR 2032) with the correct polarity in the socket (the positive pole is on the retaining bracket – see picture at the bottom on the right).
Reinsert the PCB correctly (LCD face up) into the housing (see picture in the middle on the right).
Reassemble the housing. Use the 4 screws to fix the cover again.

Environmental Reference
