load, it is suggested that you connect an external
snubber network (RC) across the terminals in
accordance with the following table (or use

• Do not run sensor input wires together with power
cables.
• For thermocouple (TC) wiring, use matching
thermocouple extension wire (i.e. for J T/C, use type
“J” thermocouple extension wire).
• When using shielded sensor cable, ground the shield
at one end only.

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.
PZ3
PZ4
PZ6
PZ7
Notes for Configuration 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.
Configuration Procedure
1. Remove the instrument from its case.
2. Set the internal switch V2 (see the following
figure) in open position.
3. Reinsert the instrument in its case.
4. Switch on the instrument. “CNF” should be displayed
in the upper display.
Note: If "CAL" indication is immediately displayed,
press the ▲ pushbutton to return to the
configuration mode (CNF).
5. Push the FUNC pushbutton.
The lower display shows the parameter code while
PZ10
PZ11
the upper display shows the actual parameter value.

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.

shows " -.-.-. " on both displays.
End of Configuration
• Push the FUNC pushbutton. The instrument will
return to the beginning of the configuration procedure.

display, but not to modify, the control parameters (PB,
TI, TD and rC).
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.

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.
Note: A 10 second timeout is operative during parameter
modification.
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.
10 Chromalox 8003 User's Manual
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.
In the output power off condition, the parameters can
always be reviewed and modified.
To return to normal control, press and hold the ▲
pushbutton and then push the FUNC pushbutton.
Press and hold both pushbuttons for more than 3 seconds.
The instrument then goes to the NORMAL DISPLAY
MODE.

Overrange or Underrange Indications
The instrument shows the OVERRANGE conditions
with the following indication on the upper display:
The instrument shows the UNDERRANGE 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.

instrument forces the control output to the minimum
possible value.
When an underrange condition is detected, the
instrument forces the control output to the maximum
possible value.
Error Messages
