Communicate with Clarity
The OIT3250B stores up to 500 user-definable
screens. Each screen can display as little or as much information as you
choose. There is no wasted space – you have control over the entire
screen. The following screen types are available to help you clearly
communicate to the OIT operator.
Message Screens
|
With the ability to embed up to 25
controller register monitors anywhere in each screen, message screens can
convey information to the OIT operator in an easy to read format while allowing
the OIT operator to change data in the controller. In addition, message screens
can be chained together to form messages longer than the display
size. |
 |
Recipe Screens
|
Recipe screens allow the OIT operator to
setup and start a batch process. Each recipe screen can include up to 20 preset
and 25 operator controlled ingredients. |
 |
Alarm Screens
|
Alarm screens keep the OIT operator informed
of alarm conditions using a message and an audible alert. The message can
include real-time information from up to 25 controller
registers. |
 |
Menu Screens
Help Screens
|
Help screens are linked to related message,
recipe or menu screens and display when the HELP key is
pressed. |

Extended Character Set
Horizontal Scrolling
Timed

Powerful Function Keys
The OIT3250B has 12 global function keys which can
be configured to display screens or turn on/off discrete coils in the
controller. The following modes of operation are available for each function
key.
| Function Key
Mode |
Operation |
| Disabled |
No operation. |
| Push On/Off |
Emulates on/off switch. Sets a discrete coil
in the controller when pressed; clears the coil when pressed again. |
| Latched |
Sets a discrete coil in the controller when
pressed. The controller must clear the coil. |
| Momentary |
Emulates momentary switch. Sets a discrete
coil in the controller when pressed; clears the coil when released. |
| Screen Display |
When pressed, displays assigned stored screen
unless password protection is enabled or an alarm screen is currently
displayed. If password protection is enabled, the OIT operator is prompted for
a password and the screen is only displayed if the password is entered
correctly. |
Easy Customization
|
With the OIT3250B you can easily and
inexpensively label the function keys and add a product ID label by simply
inserting custom legends. Once installed these legends are completely sealed
and protected. |
 |
Timer Events
The OIT3250B can be configured to display a screen
and/or set a discrete coil in the controller at a particular time during a
particular day of the week or daily. For example, you could configure the OIT
to display Screen #10 and set coil 100 every day at 8:00 a.m. Up to 16 of these
timer events can be programmed in the OIT. Timer events are checked by the OIT
once every minute.
LEDs
The OIT3250B provides three types of
LEDs:
| LED Type |
Description |
| System LEDs |
These 4 LEDs provide the OIT operator with
feedback on certain OIT events (ei.e., alarms and printing). |
| Status LEDs |
These 8 LEDs can be used to monitor 8
consecutive discrete coils in the controller. The coils are read once per
second. If a coil is set, its LED is turned on. If a coil is clear, its LED is
turned off. |
| Function Key LEDs |
Each global function key has an associated
LED. Each of these LEDs can be controlled by a discrete coil in the controller
or by the corresponding function key on the OIT. |
Rugged & Reliable
Tough enough to function almost anywhere, the
OIT3250B is sealed to NEMA 4/12 standards and meets CE specifications for
electric noise immunity in commercial, light and heavy industrial environments.
Reliability is not sacrificed to keep this product affordable. We use the best
components available to ensure that our products operate flawlessly.
