Note: Values shown are minimum recommendations for the

protection of the controller. For a specific load, consult the respected
electrical specifications to select a suitable fuse.

The Protective Conductor terminal must be
connected for safety reasons.

The Safety European Standard EN61010-1 for measurement, control, and laboratory
equipment requires that fuses must be specified based on IEC127. This standard
specifies for a Time-lag fuse, the letter code ÒTÓ. The above recommended fuses are
of the type IEC127-2-sheet III. Be aware that there are significant differences
between the requirements listed in the UL 248-14/CSA 248.14 and the IEC 127 fuse
standards. As a result, no single fuse can carry all approval listings. A 1.0 Amp IEC
fuse is approximately equivalent to a 1.4 Amp UL/CSA fuse. It is advised to consult
the manufacturerÕs data sheets for a cross-reference.

Use copper conductors only for power
connections

The figures below show the input connections and input connector jumpers

required to hookup a 2, 3 or 4-wire RTD.
The two-wire connection is the simplest method, but does not compensate for lead­wire temperature change and often requires calibration to cancel lead-wire resistance
offset.

The three-wire connection works best with RTD leads closely equal in
resistance. The controller measures the RTD, plus upper and lower lead drop
voltage and then subtracts twice the measured drop in the lower supply current
lead producing excellent lead-resistance cancellation for balanced
measurements.

The four-wire RTD hookup is applicable to unbalanced lead resistance and
enables the controller to measure and subtract the lead voltage which produces
the best lead-resistance cancellation.When configuring your controller, select
RTD type and RTD value in the Input Type Menu (see part 3).

3.1 Introduction

The Controller has two different modes of operation. The first, Run Mode, is used to
display values for the process variable, setpoint value and to display or clear peak
and valley values. The other mode, Menu Configuration Mode, is used to navigate
through the menu options and configure the controller.

Part 3 of this manual will explain the Menu Configuration Mode. For your

controller to operate properly, the user must first "program" or configure the
menu options in the Menu Configuration Mode.

The Controller becomes active as soon as it is connected to a power source. It has
no On or Off button. The Controller will at first flash reset on the PV and software
version number on the SV display, and then proceed to the Run Mode.

The ON/OFF control is a coarse way of controlling the process. The

"Dead Band" improves the cycling

associated with the On/Off control. The PID control is best for processes where the setpoint is continuously
changing and/or a tight control of the process variable is required. PID control requires tuning and adjustment
of the

"Proportional", "Integral or Reset" and "Derivative or Rate" terms by a trial-and-error method. The

Controller provides an

"Auto Tuning" feature making the tuning process automatic, possibly optimum.

Where "*" is the selected Recognition Character. You may select any ASCII table symbol from "!" (HEX address "21")
to the right-hand brace (HEX "7D") except for the caret "^", "A", "E", which are reserved for bus format request. "(nn)"
are the two ASCII characters for the device Bus Address. Use values from "00" to hex "C7" (199 decimal).

"ccc" stands for the hex-ASCII Command Class letter (one of eleven given in table 3.12), followed by the two Hex­ASCII Command Suffix characters identifying the meter data, features or menu items to which the command is directed
(given in table 3.13).

"<data>" is the string of characters containing the variable information the computer is sending to the meter. These
data (whether BCD or binary) are encoded into Hex-ASCII characters, two characters to the byte. Square brackets
(indicating optional status) enclose this <data> string, since some commands contain no data.

"<nn>" is the device address for RS-485 communication and the max is 199 in decimal.

Examples:

1. To reset the controller, send *Z02 (Table 3.1)

2. To read Setpoint 1, send *R01 (Table 3.2)

3. To change Setpoint 1 to 100.0
