Watlow 12LS Controller - Manual (Page 9)

1-2
The ANAFAZE 12LS front panel provides an intelligent method for both viewing the process
conditions and operating the controller. Displays show information in increasing detail: bar graph
summary, single loop displays, and detailed guided setup menus. For operating security, all front
panel entries can be password protected with two levels. With the panel "unlocked" common
operator changes, such as setpoint or manual/auto, are made easier with single dedicated keys.
Detailed setup requires a password, and entries are made on guided menus. The result is a
controller that is both easy and logical to use.
The front panel features a two line alphanumeric LCD display. Different process displays are
quickly selected with the front panel push-buttons:
Bar Graph Display: Provides a system overview by displaying a deviation bar graph for
each loop. Loop status including acknowledged alarms, manual or auto are also displayed.
Single Loop Display: Highlights the detailed status for any selected loop including the
process variable, engineering units, the setpoint, any alarms, and the control output
percentage.
Scanning Display: The scanning display sequentially shows the single loop display for all
the loops.
Alarm Display: If an alarm occurs, the front panel switches to the alarm display which is
the single loop display with the alarm condition flashing. Pressing ALARM ACK stops
the flashing and allows the display to be switched to any function.
