General Operation PZ1 There are two setup modes for the 8003: • Configuration Mode • Operator Mode In general, the Configuration Mode is the initial setup of the controller when first installed. Input type and alarm setup are examples of Configuration Mode settings. The Operator Mode includes settings that might be adjusted frequently with daily control operations such as setpoints and PID parameters.

P9 = Alarm 1 Inhibit Available only when P7 is different from 0. OFF = inhibit disabled ON = inhibit enabled P13 = Type of OFFSET Applied to the Measured Value P13 = 0 = constant OFFSET (P14) all over the range P13 different from 0 = P13 shows the application point of the offset value set by P14 parameter. Note: The Alarm Inhibit disables the alarm action after a setpoint change. At startup, it automatically enables the alarm when the process temperature reaches the present condition.
P15 = Threshold of the “Soft Start” Function Enter the threshold value, in °F or °C, for the automatic start of the "Soft Start" function (output power limit). The range of this setting is determined by the range of the sensor selected in P1 (i.e., if type J T/C °F is selected in P1, range is 0-999). If the unit powers-up below the threshold value, the "Soft Start" function is enabled and limits the power output to "OLH" for "toL" minutes. “OLH” and “toL are setup in the Operator Mode.
P22 = Alarm 2 Relay Action This parameter is available only if P10 is different from 0 and P16 is different from OFF.
SMART Function Operator Mode SMART automatically determines the best PID control parameters for your application. 1. Remove the instrument from its case 2. Set the internal switch V2 in closed position 3. Re-insert the instrument 4. Switch on the instrument To enable the SMART function, push the SMRT pushbutton. The SMRT LED will light or flash according to the algorithm automatically selected.
The upper display will show the measured value while the lower display will show the programmed setpoint value (we define this status as “normal display mode”). Pushbutton functionality during operating mode : FUNC = Stores the new value of a selected parameter and increments to the next parameter. SMRT = Scrolls parameters back (in reverse order) without storing the new parameter value. ▲ = Increases the value of the selected parameter. ▼ = Decreases the value of the selected parameter.
td 8003 Operator Parameters Push the FUNC pushbutton. The lower display shows the cue, the upper display shows the value of the selected parameter. Cue Description SP Control Setpoint, range from "rL" to "rH". nnn Software key for parameter protection set in Conf mode P18. A1 Alarm 1 Setpoint, range from Conf mode P2 to P3. A2 Alarm 2 Setpoint, range from Conf mode P2 to P3. H1 Alarm 1 hysteresis (deadband) 0.1 to 10.0% of alarm span. H2 Alarm 2 hysteresis (deadband) 0.1 to 10.0% of alarm span.
Error Messages Overrange or Underrange Indications The instrument shows the OVERRANGE conditions with the following indication on the upper display: Burn-out conditions are shown as well as overrange condition. For TC input it is possible to specify optional underrange indication when ordering the controller. Contact the factory for information. Note: When an overrange condition is detected, the instrument forces the control output to the minimum possible value.
Error Messages The instrument has a self-diagnostic algorithm. When an error is detected, the instrument shows “Err” indication on the lower display while the upper display shows the code of the detected error. Note: Error List 100 150 200 201-2xx 301 305 307 310 400 500 502 510 Write EEPROM error. CPU error. Write on protected memory. Configuration parameter error.
