Troubleshooting

Select output channel interface U by using the command ´

A1

´,

Address the device with its device number ´

Gxy

´ (s. man. 6.2.1),

if the computer is in XOFF state, enter <Strg Q> for XON,

query the programming through ´

P15

´ (s. man. 6.2.3),

Only check the sending line by cycle input via command ´

Z123456´

and control in the display
Test the receiving line with the key

<PRINT>

and by monitor control.

Error:

Data transmission within the network does not function.

Remedy:

Check that all devices are set to different addresses, address all de-
vices individually via terminal and command ´

Gxy

´.

Addressed device is OK when the feedback is at least ´

y CR

LF

´.

If data transmission is still not possible, disconnect networked de-
vices, check all devices separately using the data cable of the com-
puter (see above),
check the wiring regarding short circuit or twisting.
Are all network distributors supplied with power?
Network and check the devices successively again (see above).

If the device is, after the above inspections, still not performing as specified in

the operating instructions, it must be sent to the factory in Holzkirchen, Ger-

many, including a short report and, possibly, control printouts. Additionally, the

software AMR-Control allows to print the monitor pages including the program-

ming and also to save an extensive ´function test´ in the device list or the termi-

nal operation and to print it out.

13. DECLARATION OF CONFORMITY

Ahlborn Mess- und Regelungstechnik GmbH declares herewith that measuring

instrument ALMEMO

®

2590 carries the CE label and complies in full with the

requirements of EU directives relating to low voltage and to electromagnetic

compatibility (EMC) (89/336/EWG).

The following standards have been applied in evaluating the product.

Security:

EN 61010-1:2001

IEC:

EN 61326: 2006

If a product is modified in any manner not agreed with us in advance, this dec-

laration becomes void.

When using the sensor with an extension care must be taken to ensure that

wiring is not laid alongside or close to high-voltage power cables and that it is,

if necessary, properly shielded so as to prevent spurious interference being in-

duced in the system.

The following advisory notes must be observed when operating the device :

Using the device in strong electromagnetic fields may aggravate measuring er-

rors (<50 µV at 3 V/m and 1.5 meters thermocouple sensor). After exposure to

such irradiation ceases, the device will again operate within its technical speci-

fications.
