MENU NAVIGATION

The facilities of the controller are selected from the multi-level menu using the front panel mounted buttons.

Each level within the multi-level menu offers different functions, see FUNCTIONS MENU page A3. Each function has a range of user selections or options, see FUNCTION LIST pages 16–22

In operating mode, the upper (green) display reads process temperature (PV) and the lower (orange) display reads setpoint temperature (SP).

When in program mode, settings of each function, shown in the upper display, can be made by selecting an appropriate option from the lower display.

USING PROGRAM MODE

Note: The controller will auto-exit program mode after 60 seconds of inactivity.

To enter program mode from normal operating mode

Press and hold both ▲ and ▼ buttons for at least 3 seconds.

Release the buttons together and the controller will

now display the function and option (setting of that TUNE function), e.g.

OFF

To view function on the same level and display current option

Press ▲ or ▼ button once to view the next function.

Press and hold ▲ or ▼ buttons to scroll through functions. The current option or function value is shown in the lower display.

To change an option value or setting

Press and hold the ✱ button, then press ▲ to increase or ▼ to decrease the value or select the next option.

Note: Check the new option value before moving to another function or exiting program mode.

To change levels

Press and hold ▼ to scroll through the functions until LEUL is displayed. Release ▼ to display current level. Press and hold the ✱ button, then press ▲ to increase or ▼ to decrease the level. Release buttons when required level is obtained.

To exit program mode

Press and hold both ▲ and ▼ buttons for at least 3 seconds.

Note: Control commences with any new instructions now entered in the memory.

REMINDER OF INSTRUMENT ADJUSTMENTS

Press ▲ ▼ together for 3 seconds for program entry or exit. Press ▲ or ▼ to scroll through functions.
