5.To enter setpoints for relays, enter the desired value for the process measurement or temperature at which to activate an alarm event and press ENTER/MENU.

6.To set deadband as a measurement value, enter the change in the process value needed after the relay deactivates to return to normal (and thereby preventing

repeated alarm activation) and press ENTER/MENU.

7.To set the Normal alarm condition, select Open or Closed and press ENTER/MENU. Program the normal state to define the desired alarm default state to normally open or normally closed upon power up.

8.To set USP Safety, enter the percentage below the limit at which to activate the alarm and press ENTER/MENU. NOTE: USP Safety only appears if a contacting

conductivity board is installed.

This section provides details to simulate relay action. To simulate relays, access the Program screen by pressing ENTER/MENU from the main screen and then select the Relay tab.

To simulate alarm relay conditions, access the Simulate Relay Action screen by pressing ENTER/MENU from the main Relay programming screen.

Alarm relays can be manually set for the purposes of checking devices such as valves or pumps. Under the Alarms

Settings menu, this screen will appear to allow manual forced activation of the alarm relays. Select the desired alarm condition to simulate.
