Control Loop

Closed-loop control: Component parts

• LOAD - unit to be heated, or cooled• HEATER - electrical or gas• COOLER - electrical or gas• INPUT - thermocouple, PT100, dc linear• CONTROLLER - decision making unit• OUTPUTS - solid-state relay (SSR) driver

- electro-mechanical relay

MAXVU Language

• Heat instead of Primary (or SP1)

• Heat Proportional Band

• Heat Power Limit

• Cool instead of Secondary (or SP2)

• Cool Proportional Band

• Cool Power Limit

• Pre-Tune

• Tune at Setpoint

No control direction parameter needs to be set - Heat, or Cool, or Both available

MAXVU Simplified Operation – Setup Mode

• Appears on first power up, or when reset

to factory defaults & then power cycled

• Most applications need only a few settings

• Quick set-up

• Short set-up mode reduces stepping

through unused settings

• Scaling only visible when using linear input

MaxVU Navigation

· Press u or d to navigate between parameters or modes

· To select and edit a parameter press r

· The parameter name in the lower display now flashes, ready for editing

· Press u or d to change the parameter value in upper display

Important: Press r within 60 seconds to save the change.

MaxVU Mode Structure

There are 3 main modes (or menus) on the device –

1. User Mode2. Setup Mode3. Advanced Configuration Mode User Mode - the live screen used for normal operation The process variable is always be seen in this mode

Setup Mode – allows access to the most important parameters

Advanced Configuration Mode - Adu gives access to all parameters via sub-menus

MaxVU Mode Access

Hold r and press u for Setup ModeHold r and press d for Advanced Configuration Mode Separate lock codes for Setup Mode and Advanced Configuration Mode

S.Loc Setup Mode – default10A.Loc Advanced Configuration Mode – default 20

Hold r and press u to exit

Tip: Hold d button while powering up for a read-only view of lock codes.

MaxVU Mode Access Example

For example to enter Setup Mode

1. Hold r 2. Press u for Setup Mode3. Press u until the top display shows 104. Now press r

You are now in the Setup Mode

5. Press hold r 6. and press u to exit

MaxVU – Returning to User Mode

The User Mode is the normal operating mode.

Hold r and press u

From a sub-menu in Advanced Configuration Mode do this twice:

• Once to return to Advanced Configuration Mode (Adu)• Hold r and press u to exit Adu

You will return to the normal User Mode with the PV displayed

Set-Up Mode parameters

Set up the following:

Input type = PT100

Units = °F

Display Units = 000.0 (1 decimal point)

Output 1 = Heat

Output 2 = Cool

Output 3 = Alarm 1 or 2

Alarm 1 = 300.0°F

Alarm 2 = 100.0°F

Set-point = 250.0°F

Pre-Tune

Pre-Tune will not engage when:• On-Off control• Controller is set to Manual• Setpoint ramping• PV less than 5% of the input span from the Setpoint

Note: Same as West however unlike the P series there is no Pre-tune on power up setting on MaxVU

Select / Read Unit

Read from Device

“Online” mode

Set up using the configuration tabs

Select the parameter category

Change parameter setting by directly entering value or drop down – similar to blue control

Set up Wizard

Select parameter setting from simplified tables

Help screen shown on right hand side of window

Use the configuration software to set up MAXVU as below:

Input type = PT100 RTD, scaled 0 to 600

Units = Fahrenheit, 1 decimal place.

Output 1 is Heat Output 2 is Cool Output 3 is Alarms 1 or 2

Alarm 1 = Band alarm 450.0°F (hysteresis of 5)

Alarm 2 = Process low alarm 300.0°F (hysteresis of 1)

Set-point = 470.0°F

MAXVU Group Exercise 4 – PC Configurator Software

MaxVUExtra Exercises (if required)

Check the present set-point value

Adjust the set-point to +100

Use the front panel to factory default the MaxVU

Now check the set-point value

What happens if you power cycle after factory

default?

MAXVU Group Exercise 5 – Factory Default

Power down the MaxVU

Power up MaxVU with u pressed for 10 seconds

What happens?
