Display And Operator Controls - Samson TROVIS 6495 Series Mounting And Operating Instructions

5.2 Display and operator
controls
Display
The controller is in the operating level while
the controller is in operation.
The display is divided into two sections.
Each section is assigned to one controller.
The default assignment is as follows:
4
Left display: Controller [1]
4
Right display: Controller [2]
The controlled variable (actual value), error,
set point and manipulated variable (output)
are displayed for each controller in the de-
fault setting.
Status messages concerning the digital in-
puts and outputs can be displayed depend-
ing on the configuration. For control modes
with just one controller, further signals can
be displayed in five rows in the additional
display.
Infrared interface
Data are transmitted between the controller
and TROVIS-VIEW installed on the computer
over the infrared interface of the controller
and the infrared adapter (order no.
8864-0900) connected to the computer.
DIP switches
Before an analog input can be configured,
the DIP switches must be set correspond-
ingly. These switches are used to initially se-
lect whether an input is to accept a cur-
rent/voltage signal (mA, V) or a resistance
signal (Pt 100, Pt 1000, potentiometer).
To make the initial setting effective, both DIP
switches of an analog input must have the
same position. If just one DIP switch is
switched, the last valid configuration of the
input remains effective. An error message is
generated and the digital output for error
messages DO7 is activated. The fault alarm
icon is displayed in the operating level
(see section 12).
Two DIP switches are assigned to each ana-
log input AI1 to AI4.
