2 SETTING UP

2.1 Instrument Power-up – Fig. 2.1

Caution. Ensure that all connections, especially to the earth stud, are made correctly.

a) Check that the input sensors are installed correctly.

b) Switch on the supply to the instrument, any power-operated control circuits and the input

signals.

c) The start-up sequence shown in Fig. 2.1 is displayed when the supply is first switched on.

2.2 Simple Fault-finding

If the instrument does not appear to be working satisfactorliy, carry out the following checks

before contacting the Service Organization:

• Are all connections made correctly?

• Is there power to the instrument?

• Is there a signal at the process variable input and/or the control output terminals?

Line Failed indicates power

has been restored after a

failure. Cleared by pressing

the switch.

Instrument Test identifies the instrument type, C300, C301

or C310 –see

5 OPERATING LEVEL

5.1 Operating Page Introduction

5.1.1 Set Point Tracking

With set point tracking enabled (in the Set Points Page), the Local set point value tracks the

process variable when the controller is in Manual control mode. In this mode of operation the

set point limits do not apply. If the set point value is outside its limits when Automatic control

mode is selected, the local set point remains outside its limits and can only be adjusted in one

direction, towards its limits. Once inside the limits they apply as normal.

With remote set point tracking enabled, the Local set point tracks the remote set point value

when in the remote set point mode. In this mode of operation the Local set point limits do not

apply. If the set point value is outside its limits when the Local set point value is selected, the

Local set point remains outside its limits and can only be adjusted in one direction, towards its

limits. Once inside the limits they apply as normal.

5.1.2 Auto/Manual Transfer

All auto-to-manual transfers are bumpless. If the Local set point is used and set point tracking

isenabled, all manual-to-auto transfers are bumpless, since the setpoint is always atthe same

value as the process variable. Without set point tracking enabled, the response following a

manual-to-auto transfer depends on the control settings. With an integral action setting the

outputis ramped upor downto removeany processvariable offset fromthe setpoint (providing

the process variable is within the proportional band). If the integral action is off, the output may

step to a new value when the controller is transferred back to Automatic control mode.

With remote set point tracking enabled, the control set point switches automatically from

Remote to Local when Manual mode is selected.

5.1.3 Heat/Cool Control – Fig. 6.3

When in Automatic control mode both the heat and cool outputs are turned off when in the

Output Off Hysteresis Band. In Manual control mode the Output Off Hysteresis Band has no

effect. If the PID output is within the Off Hysteresis Band when the controller is returned to auto

control mode, the Off Hysteresis Band has no effect until either the PID output goes outside the

band or becomes equal to the Crossover Value.

Remote Set Point Ratio

The remote set point input (in engineering units) is

multiplied by the ratio to obtain the control set point value, i.e.

Remote Set Point Value = Input x Ratio + Bias

Use the and the switches to set the ratio required,

between 0.010 and 9.999 in 0.001 increments

Remote Set Point Bias

The bias value is added to the remote set point value (see

previous frame) Use the and the switches to set
