To program limit functions, use the MODE/DN button or magnetic switch to select the LIMIT
display. Press and hold the ENT button or maintain the ENT magnetic switch. The display will
first show a P in the lower left-hand corner and will then highlight the L1 indication with a
blinking cursor. Use the SEL button or magnetic switch to select the function of the limit
assignment. Use the ENT button or magnetic switch when the desired mode is displayed for L1.
The cursor will now highlight the numeric value to be entered for L1. Entries correspond with
the scaling factor, decimal location and engineering units for the function selected. The left-most
digit will highlight with a blinking cursor. Move the cursor left to right using the SEL button or
magnetic switch. Use the UP or DN button or magnetic switch to increment or decrement each
digits value. When editing is complete and the desired value is displayed, use the ENT button or
magnetic switch to store the programmed value for L1. If a RATE assignment has been made,
the RT-Ex15 will next prompt the user to enter the RATE LIMIT MARGIN in percent. The left-
most digit will be highlighted with the blinking cursor. Move the cursor using the SEL button or
magnetic switch. Use the UP or DN button or magnetic switch to increment or decrement each
digits value. When editing is complete and the desired value is displayed, use the ENT button or
magnetic switch to store the programmed RATE LIMIT MARGIN. The RT-Ex15 will then
highlight the L2 indication with a blinking cursor. Repeat the procedures used for L1. When the
L2 programming is complete, use the ENT button or magnetic switch to store the programmed
values and exit LIMITS programming.
NOTE: See Wiring Connections and Connection Diagram on page 3 for information regarding
connection to limit outputs.
RATE A / TOTAL A Display Mode
RATE A GT and TOTAL A (Job Total) are viewed on the same screen using the RATE A_TOT A
display. Rates and totals are displayed in the corresponding engineering units based on the
programmed KFR and KFT factors and decimal locations. The GR TOTAL can be viewed using
the SEL button or magnetic switch to switch between TOTAL A (TA) display and GR TOTAL
A (GA) display as illustrated below. After a power cycle, the RT-Ex15 will revert to the Job
Total (TA) display). Total A can be reset from this display using the RESET/UP button or
magnetic switch. Typical displays would be:
The RAT A TOT A display is only for viewing the rate and total simultaneously and has no
programming function. Rate and Total variables are programmed from the RATE A
GT or RATE
A PL and TOTAL A screens respectively.
