Figure 4 shows the wiring diagram for the process current input using either internal or external
excitation. The benchtop unit provides 5V excitation by default and can also output 10V, 12V or 24V
excitation voltages. Refer to the Platinum Series User’s Manual (M5451) for more information on
selecting the excitation voltage.
Figure 4. 4-20 mA Sensor Wiring Diagram.
Figure 5 shows the wiring for ratio-metric bridge inputs. Connect the resistors R1 and R2, included in the
provided Wire Kit, across terminals 4 and 6 and terminals 1 and 8 respectively. This allows the Bridge
voltage to be measured.
When powering a bridge from the unit use an internal excitation voltage of either 5V or 10V. External
excitation may also be used but must be kept between 3V and 10V and be ground isolated from the
unit.
Figure 5. Bridge Wiring Diagram.
3.3 Universal Thermocouple Connector
The Benchtop Digital Controller accepts
miniature thermocouple connectors. Ensure
the polarity of the connector is correct as
indicated in Figure 6. The wide terminal of the
miniature connector is negative.

4CONFIGURATION AND PROGRAMMING
This section outlines the initial programming and configuration of the Benchtop Digital Controller. It
gives a brief outline on how to setup the inputs and outputs, and how to configure the setpoint and
control modes. Refer to the Platinum Series User’s Manual (M5451) for more detailed information on all
the controller’s functions.

Figure 9. Example of CS8DPT Series Display.
Description of Button Actions
The UP button moves up a level in the menu structure. Pressing and holding the UP
button navigates to the top level of any menu (oPER, PRoG, or INIt). This can useful if you
get lost in the menu structure.
The LEFT button moves across a set of menu choices at a given level. When changing
numerical settings, press the LEFT button to make the next digit (one digit to the left)
active.
The RIGHT button moves across a set of menu choices at a given level. The RIGHT button
also scrolls numerical values up with overflow to 0 for the flashing digit selected.
The ENTER button selects a menu item and goes down a level, or it saves a numerical
value or parameter choice.

Initialization Mode: These settings are rarely changed after initial setup. They include
transducer types, calibration, etc. These settings can be password-protected.
Programming Mode: These settings are frequently changed. They include Set points,
Control Modes, Alarms, etc. These settings can be password-protected.
Operating Mode: This mode allows users to switch between Run Mode, Standby Mode,
Manual Mode, etc.

to maintain the input value at the setpoint using the selected outputs.
In the program menu, using the return button, select the SP1 parameter. Use left and right
buttons to set the process goal value for PID and oN.oF control modes.
Refer to Section 4.5 and Section 4.6 for more information on setting up control modes.
