12. Trouble-shooting
Remedy
Check the interface module, connections, and settings. Ensure that
both devices are set to the same baud rate and transmission mode.
(see Manual, 6.10.12) A reset with the interface module connected
will set the baud rate to 9600 baud. (see 7.4) Ensure that the correct
COM port on the computer is being addressed. Is a printer in the ON-
LINE status ? Test data transmission by means of a terminal (ALME-
MO
®
Control, WinControl, WINDOWS Terminal). Address the device
using its assigned device number '
Gxy
'. (see Man. 6.2.1) If the device
is in the XOFF status, enter <ctrl Q> for XON. Check the program-
ming by means of '
P15
'. (see Man. 6.2.3) Test the transmit line only
by entering the start command 'S2'; the LED START should light up.
Test the receive line only by pressing the START / STOP key.
Error
Data transmission in the network does not function.
Remedy
Check to ensure that all devices are assigned different addresses.
Address 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. En-
sure that all network distributors are supplied with power. Network
the devices again one after the other and check successively. (see
above)
If, after performing the above-listed checks and remedial steps, a 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 des-
cription, and if available test printouts. With the ALMEMO
®
Control software
you can print out screenshots showing the relevant programming details and
save and / or print out a comprehensive 'function test' in the device list or termi-
nal mode.
13. ELECTROMAGNETIC COMPATIBILITY
The following advisory notes must be observed when operating the device.
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
and that, if necessary, they are properly shielded so as to prevent spurious in-
terference being induced in the system.
