Declaration Of Conformity - Ahlborn ALMEMO 2470-1S Operating Instruction

14. Trouble-shooting
Remedy The calibration of a measuring range may have become misadjusted.
The device must be recalibrated at our factory.
Error Data transmission via the interface does not function.
Remedy Check the interface module, connections, and settings. Ensure that
both devices are set to the same baud rate and transmission mode.
Is the correct COM port on the computer being addressed? To check
the data flow and the handshake lines a small interface tester with
LEDs comes in very handy; (in ready-to-operate status data lines
TXD, RXD carry negative potential of approx. -9V and their associated
LEDs light up green whereas handshake lines DSR, DTR, RTS, CTS
carry positive voltage of approx. +9V and their associated LEDs light
up red. For the duration of data transmission the data LEDs should
flash red.
Test data transmission by means of a terminal (AMR-Control, WIN-
Control, WINDOWS-Terminal).
signed device number ´Gxy´. (see Manual, 6.2.1) If the computer is in
XOFF status. enter <ctrl Q> for XON. Check the programming by
means of ´P15´. (see Manual, 6.2.3) Test the transmit line by selecting a
measuring point with command ´Mxx´ and checking 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 all devices individually via the terminal using 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 a brief explanatory note, error de-
scription, and if available test printouts. With the AMR-Control software you
can print out screenshots showing the relevant programming and save and / or
print out a comprehensive "Function test" in the device list or terminal mode.
