• When a relay output is used to drive an inductive
load, it is suggested that you connect an external
snubber network (RC) across the terminals in
accordance with the following table (or use

General Operation
PZ1
There are two setup modes for the 8003:
• Configuration Mode
PZ3
PZ4
• 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.

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).
• When configuration is completed, the instrument
shows " -.-.-. " on both displays.
End of Configuration
• Push the FUNC pushbutton. The instrument will
return to the beginning of the configuration procedure.
For Advanced Configuration
• Push the ▲ or ▼ pushbutton and set the “217” code on
the upper display.
• Push FUNC. The following advanced configuration
parameters, P19-P29 will be displayed.
If the unit powers-up below the threshold value, the "Soft

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
To enable the SMART function, push the SMRT
pushbutton. The SMRT LED will light or flash according
to the algorithm automatically selected.
4. Switch on the instrument
PZ1
When the SMART function is enabled, it is possible to
display, but not to modify, the control parameters (PB,
TI, TD and rC).
PZ3
PZ4
When the traditional PID control is desired, push the
SMRT pushbutton again. The instrument maintains the
last set of SMART PID control parameters and enables
parameter modification.

Notes: 1. When ON/OFF control is programmed (PB = 0),
the SMART function is disabled.
2. The SMART enabling/disabling is protected by
security code.

lower display will show the programmed setpoint value
(we define this status as “normal display mode”).
Output Power Off
To turn OFF the output signal, push and hold the ▲
pushbutton, then push FUNC. Pressing both pushbuttons
for more than 3 seconds will cause the instrument to
display "OFF" instead of the setpoint value.

If, during operator parameter modification, no
pushbuttons are pressed for more than 10 seconds, the
instrument goes automatically to the “normal display
mode” and it stores only the new settings that were
followed by pressing FUNC pushbutton.

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
