This section describes how the current outputs and alarm relays can be manually set for the purposes of checking devices such as valves, pumps, or recorders.

1.From the main menu, move the cursor down to "Program" and press Enter 4. On this display, move the cursor to "Simulated tests" and press Enter 4.

2.At this point there are six separate screens for testing each of the current outputs and each of the alarm relays. Highlight the desired item by pressing the arrow b t keys as needed.

When the desired item is highlighted, press Enter 4 to continue. Go to step 3a for outputs and 3b for alarms.

NOTE

A cautionary message will appear to warn that the out- put or alarm that was selected will be changed by the fol- lowing action. Be sure to alert plant personnel that these changes are simulated and do not represent a change in the actual process. Press Enter 4 to contin- ue or Abort 1 to cancel the simulation.

3a. The output is now being simulated. In the example to the left, out- put 1 has been set to 10.00 mA. The output will remain at 10.00 mA until either Exit 1 (or Edit 4 see below) is pressed or the test is concluded by timeout. The default value for the timeout is 10 min- utes, so after 10 minutes, the output would go back to normal oper- ation. To configure the timeout option, see Section 5.5.

If the displayed current is not the desired value, press the Edit 4 key and the next screen will allow changing the value. Use the arrow keys to change the display as needed, and press Test 4 to use that value. Press Esc 3 to cancel the change in the value and contin- ue simulating the previous current.
