The routing diagram is shown in section 16.2.
13.1 In general
When configuring the 9202, you will be guided through all parameters
and you can choose the settings which fit the application. For each
menu there is a scrolling help text which is automatically shown in line
3 on the display.
Configuration is carried out by use of the 3 function keys:
will increase the numerical value or choose the next parameter
will decrease the numerical value or choose the previous parameter
will save the chosen value and proceed to the next menu
When configuration is completed, the display will return to the default
state 1.0.
Pressing and holding
will return to the previous menu or return to the
default state (1.0) without saving the changed values or parameters.
If no key is activated for 1 minute, the display will return to the default
state (1.0) without saving the changed values or parameters.
13.2 Further explanations
13.2.1 Password protection
Access to the configuration can be blocked by assigning
a password. The password is saved in the module in order
to ensure a high degree of protection against unauthorised
modifications to the configuration. Default password 2008
allows access to all configuration menus.
Password protection is mandatory in SIL applications.
13.2.2 Cable fault information via display front 4501
Cable fault (see limits in the table) is displayed as CA.BR
(cable break) or CA.SH (cable short-circuited). Cable fault is
shown independently for each channel but the configuration is
common for both channels. In case of cable fault the backlight
flashes. This can be reset by pressing the
key. When the
cable fault has been remedied, the module will return to normal
operation.
13.4 Advanced functions
The unit gives access to a number of advanced functions which can be
reached by answering “Yes” to the point “adv.set”.
