lockout information)
Associated with each mode is a series of unique displays that are accessed via the front
keypad.
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 5.4 & 5.5 of this manual (page 46 - 54).
Shipped Configuration/Jumper Positioning 3.2
Each instrument is factory shipped ready to accept a thermocouple 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
instrument 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 62). 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.

Operation Summary 3.3
3.3.1 MODE SELECTION
If the instrument is either in the Off mode, the Operation mode (recorders), or the Control
mode (recording controllers), repeated pressing and releasing 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 if the mode is on.
Entry into any mode except the Operate, Control, Tune, Manual, or Enable modes, will cause
the output(s) to turn off and any process re-transmission value output(s) to be 0 %. Entry into
the Off mode will cause process re-transmission to remain active.
