User manual
- this parameter sets the access to the configuration registers of the device. Possible values:
"mbAc"
"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 i 05h cant be denied by "mbAc" parameter (see: LIST OF REGISTERS).
- this parameter defines maximal time (sec) between following frames received by the device. If the delay will be
greater than the value of "mbtO" parameter, the relays and analogue outputs which are controlled via RS-485
"mbtO"
interface, will set to alert state (see "OUtP" menu, and "rEL1" menu description). Parameter "mbtO" can be set
to values from 0 to 99 seconds. The value 0 means that the time will be not controlled.
- this parameter defines minimal (additional) delay between the Modbus message and the answer of the device
"rESP"
(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:
"Std"
" 10c"
" 20c"
" 50c"
"100c"
"200c"
In the most cases parameter "rESP" should be set to "Std" (no additional delay). Unfortunately for
some third party RS-converters "rESP" should be adjusted experimentally. Table 7.1 contains most
frequently used values.

7.3.11. "Edit" parameter

"dig" - the change to "by digit" mode,
"Slid"
- slide change mode.

7.3.12. "dEFS" parameter

This setting allows to restore the factory settings of the device. To get the access to this option special
password is required: „5465", next the device displays acknowledge question „SEt?". Press [ENTER] to
acknowledge the restoring of factory settings or [ESC] to cancel.

7.3.13. "SErv" menu

This menu contains the parameters for authorized service only. To enter this menu proper service password
must be entered. Improper settings can causes of damage of the device.
- answer as quick as possible, no additional delay
- answer delayed of 10, 20, 50, 100 of 200 chars respectively, where one character
time depends on selected baud rate
