Test data transmission by means of a terminal (AMR-Control, WIN-
Control, WINDOWS-Terminal) : Address the device using its as-
signed device number Gxy (see Manual, Section 6.2.1), Check the
programming by means of P15 (see Manual, Section 6.2.3), Test the
transmit line by entering a cycle with command ´Z123456´ and check
in the display. Test the receive line by pressing the
MANU/PRINT
key
and check in the display
Error :
Data transmission in the network does not function.
Remedy : Check to ensure that all devices are set to different addresses; ad-
dress devices individually via terminal and command
Gxy
; addressed
device is OK if at least y CR LF is returned as echo;
If transmission is still not possible, unplug the networked devices;
check all devices individually on the data cable to the computer (see
above); check the wiring for short-circuit or crossed wires.
Are all network distributors supplied with power ?
Network the devices again one at a time and check successively (see
above)
If, after performing the above-listed checks and remedial steps, the device still
fails to behave as described in the operating instructions, it must be returned to
our factory in Holzkirchen, accompanied by an explanatory note, error descripti-
on, and if available test printouts. With the AMR-Control software you can save
and / or print out the relevant screen displays with programming or the relevant
terminal operations.
11. Electromagnetic compatibility (EMC)
ALMEMO
®
measuring instrument 2390-5 complies in full with the safety require-
ments specified in the EU directive on the harmonization of laws in EU member
states relating to electromagnetic compatibility (EMC) (89/336/EWG).
The following standards have been applied in evaluating the product :
IEC 61326:1997+A1:1998+A2:2000
IEC 61000-6-1:1997
IEC 61000-6-3:1996
IEC 61000-4-2:
1995+A1:1998+A2:2000
8kV
IEC 61000-4-4:
1995+A1:2000
2kV
IEC 61000-4-3:
1995+A1:1998+A2:2000
3V/m
The following advisory notes must be observed when operating the device :
1. If the standard sensor is extended (1.5 meters) care must be taken to ensure
that the measuring lines are not laid together with high-voltage power cables
or that they are properly shielded so as to prevent spurious interference from
being induced in the system.
2. Using the device in strong electromagnetic fields may aggravate measuring
errors (<50 µV at 3 V/m and 1.5 meters thermocouple sensor). After expo-
sure to such irradiation ceases, the device will again operate within its techni-
cal specifications
