User manual - WEIGHT METER SWI-94
7.3.9.
”SECUr” menu
This menu contains presets connected with availability of other parameters:
”SEtCod”
- user password (4-digits number). If this parameter is set at value
“0000”
, user
password is turned off.
If the user do not remember his password, the access to the menu is
possible by the “one-use password”. To get this password please contact
with Marketing Division. “Single use password” can be used only one time,
after that it is destroyed. Entering this password causes in clearing of user
password, it means sets the user password to „0000”.
The “one-use password” can be used
ONE TIME ONLY
, it is impossible to use it
again! The “one-use password” can be restored by Service Division only.
“Acc r1, Acc r2”
- this option permits user (
”on”
) or prohibits (
”oFF”
) to modify the
thresholds of the relays/LEDs R1, R2 without knowledge about user password.
7.3.10.
”rS-485” menu
This menu is connected with RS-485 interface, and sets his properties:
”Addr”
- this parameter defines the address of the device, accordingly to Modbus protocol.
It can be set in range from 0 to 199. If the value 0 is set then device, responds to
frames with address 255 (FFh).
”bAud”
- this parameter determines RS-485 interface baud rate. It can be set to one of 8
possible values:
”1200”
,
”2400”
,
”4800”,
”9600”
,
”19200”,
”38400”,
”57600”,
”115200”
.
”mbAccE”
- this parameter sets the access to the configuration registers of the device.
Possible values:
”on”
- configuration registers can be set via RS-485 interface,
”oFF”
- configuration registers can not be set via RS-485 interface.
The access to registers no 04h and 05h cant be denied by
”mbAccE”
parameter
(see:
LIST OF REGISTERS
).
”mbtimE”
- this parameter defines maximal time (sec) between following frames received by
the device. If the delay will be greater than the value of
”mbtimE”
parameter, the
relays and the analogue output which are controlled via RS-485 interface, will set
to alert state (see
"OUtPUt" menu
and
“rELAy1” menu
description). Parameter
“
mbtimE
” can be set to values from 0 to 99 seconds. The value 0 means that the
time will be not controlled.
”rESP”
- this parameter defines minimal (additional) delay between the Modbus message
and the answer of the device (received and sent via RS-485 interface). This
additional delay allows the device to work with poor RS-converters which do not
works properly on baud rates higher than 19200. This parameter can be set to one
of values:
38
