Prior to first time operation of the instrument, the configuration procedures for the Program
and Tune modes must be performed as applicable. Calibration and Test modes are not used
as part of the instrument configuration or operation. These are used for service and mainte-
nance functions and are discussed in Section 5.6 (page 59) of this manual.
Shipped Configuration/
Jumper Positioning 3.2
Each instrument is factory shipped ready to accept a RTD input on TB 4 and TB 5. All
parameters in each mode are set to default values. These defaults are shown in tabular form
after the description for each mode. Instrument AC power input is as specified in the instru-
ment model number and is shown on the ratings label. The 230 VAC option includes a switch
in the instrument for selecting either 230 VAC or115 VAC input power. If this feature is
provided, verify AC input and switch position before applying power to the instrument.
3.2.1 JUMPER POSITIONING
Jumpers are used to condition the sensor inputs and to provide a security lockout feature. All
jumpers are located on the instrument Processor board. The instrument board layout and
jumper locations and functions are shown in Appendix A-1 (Page 68). Check the jumper
positions in the instrument and verify that they are in the proper position for the intended
application.
The sensor input jumpers JU4, JU5, JU6 and JU7 condition the sensor input signals
and must be used in conjunction with input type selections made in the Program mode
(page 30).
Operation Summary 3.3
3.3.1 MODE SELECTION
If the instrument is either in the Off mode or the Control mode repeated pressing and releas-
ing of the SCROLL key will cause the instrument to display the code corresponding to each
mode that is enabled. To enter a mode, while the code is displayed, press the DOWN key. If a
mode does not appear, refer to the Enable mode section for information on how to determine
that the mode is on.
Entry into any mode except the Control, Tune, Manual and Enable modes, will cause the
output(s) to turn off and any process re-transmission value output(s) to be 0 %.
Entry into Off mode will cause the process re-transmission output to remain active.
Start Up Procedures 3.4
All configuration parameters are listed in Tables 3-1 through 3-5.
For a single pen instrument, parameters for each mode are displayed in the upper right
display. If the instrument being configured is a two pen model, a sequence of applicable
parameters will be displayed in the Pen 2 display after the Pen 1 parameters have been
reviewed and configured. After the Pen 2 parameters have been completed, parameters
common to both pens will be configured and displayed in the Pen 1 display.
