4.This screen allows you to choose the items displayed on the third line left and right of the main display screen. The process temperature and output 1 value (in mA or %) are always shown on line 2 of the main display. This screen allows you to make the following choices:

Lower Left of Main Display

• AL 1 (alarm 1 setpoint - no units shown)

• AL 2 (alarm 2 setpoint - no units shown)

• AL 3 (alarm 3 setpoint - no units shown)

• AL 3 (alarm 3 setpoint - no units shown)

• In (sensor mV input)

• In (sensor mV input)

• GI (glass impedance in Megohms)

Esc Save

The "Display contrast" selection allows the display to be made lighter or darker. Entry 0 is the lightest and 9 is the darkest. The display changes as the number is changed.

To change any of these items, use the arrow key to highlight the desired item and press Edit 4. Use the arrow keys to make the change and press Save 4 to enter the change into memory. Press Esc 3 to abort.

Display contrast: 5

Timeout: On

Timeout Value: 10 min

5.The timeout feature works on both the display and simulated tests using the current outputs and alarm relays.

The display timeout will return the display to the main display screen (from any other screen) if no key is pressed before the timeout value. This is useful because the main display screen is usually the most important screen to the operator.

The timeout feature also allows simulating the current output and

ExitEdit alarm actions with an automatic return to normal operation. When the feature is turned on (the default), simulated tests (see Section 5.4 for details) will be completed automatically when the timeout value is reached.

As before, to change these settings, use the arrow key to highlight the desired item and press Edit 4. Use the arrow keys to make the change and press Save 4 to enter the change into memory. Press Esc 3 to abort.

SECURITY CAUTION

The Timeout Value is also used by the controller to acti- vate security (Section 7.1). After unlocking the controller by entering a security code, security is not re-activated unless a display timeout occurs. If Timeout has been turned off here, security will never re-activate.
