6.7 SETTING THE TIME BASE (Models 2000, 2001 and 2003 only)
A time base must be selected when a TIMER is included.
UNITS UU
You can select Hours:Minutes (H:M) or Minutes:Seconds (M:S) for the time base. Push the NO key to
TIME H:M
change the selection. When the time base is correct, push the PARAM DISPLAY key to advance to the
next display.
6.8 SETTING THE SPAN
The next two displays are LO and HI span. Span is the LO and HI limits outside of which the system is
not to operate. The controller automatically limits all setpoints and alarms to be within this span.
The controller stores in permanent memory the maximum allowable spans for all listed thermocouples and
RTD inputs. Unless ordered otherwise, the maximum span will appear on these displays. You can select
any span up to the stored limits for thermocouple and RTD inputs. Push the UP arrow to read the
maximum programmed limit.
Process type inputs are limited to any span between -3200 and +3200 units. You can assign any display value to the LO
SPAN and HI SPAN within these limits and the controller will automatically linearize all values in between. Use the arrow
keys to change values. Advance from LO to HI SPAN using the PARAM DISPLAY key. The LAST key will back up from
HI to LO SPAN. Both direct and reverse spans are allowable.
CONFIGURATION calibration for controllers with thermocouple or RTD input is now complete. If you have this type of
controller proceed to paragraph 6.11.
If you have a process input controller, three more displays are available. Push the PARAM DISPLAY key and proceed to
Section 6.9.
6.9 SETTING THE DECIMAL POINT
This display allows the selection of decimal point position from zero (no DECIMAL decimal point) to the
third place from the right (i.e., 0.783). Use the PLACES X arrow keys to select the decimal point position.
When the decimal position is correct, push the PARAM DISPLAY key to advance to the next display.
6.10 SETTING THE DISPLAY RANGE
This display is used to program the desired display indication at minimum input. For example: LO VAL
can be set to indicate 0 for a 4 mA input level. After setting the desired reading using the arrow keys,
press the PARAM DISPLAY key.
This display is used to program the desired display indication at the maximum input. For example: HI VAL
can be set to indicate 2000 for a 20 mA input level.
The LO VAL/HI VAL procedure is the electronic equivalent of changing the scale in an analog panel meter. No input
reference calibration is required. You can change the displayed range entirely through the keypad when a process signal
such as 4-20 mA is the input.
