Manuals

The

are supplied with all instruments.

MODBUS Supplement is supplied with

Standard

instruments configured for MODBUS Serial
Communication.

The Installation manual includes an

Installation Record which should be

completed as a log of the electrical
installation. The record is useful when
carrying out initial instrument programming
and can be retained for future reference.

INSTALLATION

2.1 Preparation for
Changes to the Parameters

Ensure that the external alarm/control
circuits are isolated if inadvertent
operation during programming is
undesirable.

Any changes to the operating parameters
are implemented using the or
switches – see

Guide

Note. The instrument responds
instantly to parameter changes which
are saved when the key is
pressed.

Deadband

Deadband is set as a percentage of the position feedback
span, between 0.0 and 10.0%, to produce a deadband
around the valve control value. This gives minimum
‘hunting’ of the motorized valve.

Example. If the valve is to be driven to the 50% open

position and the deadband is set to 4.0%, the motor stops

4.4 Motorized V alve Control Without Feedback (Boundless) – Fig. 4.3

A 'boundless' process controller provides an output that is effectively the time derivative of the
required regulator position, i.e. the controller signals the regulator, not where to go (position
derivative), but in which direction to travel and how far to move, by a series of integral action
pulses. Thus, the controller does not need to know the absolute regulator position and is
unaffected when the regulator reaches the upper or lower limit, as determined by the
regulator's limit switches (giving rise to the term 'boundless').

In this system, the final regulator must act as an integrator, integrating both the raise and lower
pulses in direction and duration so that the final position of the regulator reproduces the
required 2- or 3-term control function. The regulator must remain stationary indefinitely in the
absence of raise or lower commands.

When a deviation from set point is introduced, the regulator is driven for a length of time
equivalent to the proportional step. The regulator is then driven by integral action pulses until
the deviation is within the deadband setting.

Fault Detection Level Percentage, Process Variable
Input

A fault level percentage can be set to detect a deviation
above or below the display limits. E.g. if set at 10.0%, then
if an input goes more than 10% above full scale value or
more than 10% below zero value, a fault is detected.
On some ranges the input circuitry may saturate before the
fault level set is reached. In this case an error is detected at
a level below that which is set.
Control actions and control outputs in the event of a fault
are programmable – see below.
Set the value required, between 0.0 and 100.0% in 0.1%
increments.

Information.

• Process variable, Remote set point and position feedback inputs do not require
recalibrating when the input type or range is changed.

• Scale Adjustment Reset – removes any previously programmed offset or scale
adjustment settings.

• System offset errors – can be removed using Offset Adjustment.

• System scale errors – can be removed using Span Adjustment.

• Offset/Span Adjustment – can be used to perform spot calibration.

Switch off the power supply. Connect accurate signal sources, suitable for simulation over the
entire input ranges, in place of the process variable signal connections (terminals 10, 11, 12),
remote set point signal connections (terminals 7, 8 and 9) and position feedback connections
(terminals 4, 5 and 6). For thermocouple inputs, connect the millivolt source using appropriate
compensating cable – see
thermometers, the resistance box may be connected at the sensor end of the leads or the lead
resistance must be added to the calibration values.
As a general rule, spot calibration values should be:

< 50% of range span value when using Offset Adjustment parameters.
> 50% of range span value when using Span Adjustment parameters.
