- The document provides an agenda for MAXVU technical support training, covering an overview of MAXVU, control recap, modes and configuration. - MAXVU has universal inputs, relay and SSR outputs, RS485 option, and 1/16 DIN size. It supports thermocouples, RTDs, and linear inputs but not all thermocouple and RTD types. - The training covers MAXVU modes including user mode, setup mode, and advanced configuration mode accessed via passwords. Configuration software allows programming via PC.

Focus on MaxVU

21. 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

22. 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

 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.

29. MaxVU Mode Structure
There are 3 main modes (or menus) on the device –
1. User Mode
2. Setup Mode
3. 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

30. MaxVU Mode Access
Hold r and press u for Setup Mode
Hold r and press d for Advanced Configuration Mode
Separate lock codes for Setup Mode and Advanced
Configuration Mode
S.Loc Setup Mode – default10
A.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.

31. MaxVU Mode Access Example
For example to enter Setup Mode
1. Hold r
2. Press u for Setup Mode
3. Press u until the top display shows 10
4. Now press r
You are now in the Setup Mode
1. Press hold r
2. and press u to exit

32. 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
1 2

33. Set-Up Mode parameters

34. Set up the following:
Input type = PT100

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

45. 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
