3 Operation
3.1 Power-Up Sequence
When the system first powers up, the model designation scrolls across the digital display
several times identifying the controller as a dS 600, a dS 600P, or a dS 600PC. After displaying
the model number, the controller displays the probe ID by flashing alternately, for two seconds,
the letters Prb and the number 0 indicating the P80T30 probe is connected and functioning. If
no probe is connected or the connected probe fails to communicate with the controller, the
display flashes alternately the letters PFlt and the number 1.
For the DS600P and DS600PC models, a third value is then displayed, the numeric address of
the currently selected calibration memory. The display flashes alternately for several seconds,
SEL and the current calibration memory address.
For all models, if the calibration memory selected at power up holds valid calibration data, the
controller transitions to displaying the gauge value, a number from 0 to 100. If the calibration
memory does not hold valid calibration data, the controller displays alternately the letters nEEd
and CAL until valid calibration data is saved in the selected memory. Successful execution of
the calibration function for the selected memory clears this message and allows the gauge value
to be displayed.
If the controller is power cycled while displaying nEEd and CAL, default calibration parameters
are installed at power up and the controller precedes to display the gauge value.
3.2 User Interface
Operation of the DS600, DS600P and DS600PC systems involves calibration and parameter
adjustment using the front panel pushbutton, and message interpretation. Calibration may be
based on data collected for a single point or on data collected from two points as detailed below
under Calibration.
3.3 Pushbutton Operation
The push-button switch on the front panel of the control module serves to initiate the calibration
process and to make parameter adjustments for system setup.
3.3.1 Initiating One-Point or Two-Point Calibration
A single, quick press and release of the pushbutton initiates one-point calibration. Two
successive quick presses of the pushbutton initiates two-point calibration. See the section on
Calibration (page 11).
3.3.2 Changing Parameter Values
To view the current value of a parameter, press the pushbutton and hold it for more than 3
seconds until the appropriate parameter identifier (HtoL), or if available, (SEL), (Ltol), (Udly) or
(Id) appears on the digital display. While the pushbutton is pressed, the display cycles through
the identifiers with each one shown on the display for one and a half seconds. While the
desired parameter identifier is showing on the display, release the pushbutton and the current
value of the parameter displays for 5 seconds. To retain the current value of the parameter,
