Warnings:
• 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
Chromalox snubber P/N 0149-01305):
• 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.

Hardware Setup
To select the output type(s) and the alarm contact settings:
1. Remove the instrument from its case.
2. Move the jumpers to the desired position as shown in
the diagram.
3. Set J304 and J305 as shown in the following figure.

General Operation
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.
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
the upper display shows the actual parameter value.

P1 = Input Type and Standard Range
Range
0 = TC type L 0 / +800 °C
1 = TC type J 0 / +800 °C
2 = TC type K 0 / +999 °C
3 = TC type N 0 / +999 °C
4 = RTD type Pt 100 -199 / +500 °C
5 = RTD type Pt 100 -19.9 / +99.9 °C
8 = TC type L 0 / +999 °F
9 = TC type J 0 / +999 °F
10 = TC type K 0 / +999 °F
11 = TC type N 0 / +999 °F
12 = RTD type Pt 100 -199 / +999 °F
P2 = Initial Scale Value
Not present when P1 = 5
The initial and full scale values are used by the PID
algorithm to calculate the input span.
P3 = Full Scale Value
Not present when P1 = 5
The initial and full scale values are used by the PID
algorithm to calculate the input span.
Note: the minimum input span (P3 - P2) is 300°C or
600°F for TC input and 100°C or 200°F for RTD input.
P4 = Output Configuration
H = Heating HC = Heating / cooling
P5 = Heating Output Type
rEL = Relay
SSr = SSR
The output type selected here must match hardware
jumper setup (see page 2).
P6 = Cooling Element
Available only when P4 = HC
AIr = Air
OIL = Oil
H2O = Water
P7 = Alarm 1 Type
Available only when P4 = H
0 = None
1 = Process alarm (absolute)
2 = Band alarm (+ and - deviation)
3 = Deviation alarm
P8 = Alarm 1 Operation
Available only when P7 is different from 0
H = High Alarm L = Low Alarm
(outside if band alarm) (inside if band alarm)

P9 = Alarm 1 Inhibit
Available only when P7 is different from 0.
OFF = inhibit disabled
ON = inhibit enabled
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.
P10 = Alarm 2 Type
0 = Not provided 2 = Band alarm
1= Process alarm 3 = Deviation alarm
P11 = Alarm 2 Operative Mode
Available only when P10 is different from 0.
H = High Alarm L = Low Alarm
P12 = Alarm 2 Inhibit
Available only when P10 is different from 0
OFF = Inhibit disabled
ON = Inhibit enabled
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.
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.
P14 = OFFSET Value
When P13 = 0, P14 is programmable, in engineering
units, from -20 % to +20 % of the input range.
When P13 is different from 0, P14 is programmable from
-20 % to + 20 % of P13 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.
P16 = Not used
P17 = Not used
P18 = User Defined Security Code
0 = Security lock disabled (all Operator Mode parameters
may be adjusted)
1 = Security lock enabled (only setpoints may be adjusted)
From 2 to 499 = SP parameter may be modified and
other Operator Mode parameters may
be accessed.
From 500 to 999 = SP, A1 and A2 parameters may be
modified and other Operator Mode
parameters may be accessed.
• 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.
P19 = Main Output Action
Available only when P4 = H
r = Reverse (heating)
d = Direct (cooling)
Note: when P4 = HC, this parameter is forced to "r"
P21 = Alarm 1 Relay Action
This parameter is available only if P7 is different from 0
and P4 = H.
r = Reverse (relay de-energized in alarm condition)
d = Direct (relay energized in alarm condition)
