4.5.7Reversing The Output Action Using Actual Level Input

Adjust the level to 50% ( + or - 10% ).

Enter the calibration mode by pressing the UP & DOWN buttons together for 1 second and press the DOWN button for 1 second to set the output at

4.00mA.

Adjust the level to the new SPAN point.

Enter the calibration mode by pressing the UP & DOWN buttons together for 1 second and press the UP button for 1 second to set the output at

20.00mA.

Adjust the level to where the ZERO needs to be set.

Enter the calibration mode by pressing the UP & DOWN buttons together for 1 second and press the DOWN button for 1 second to set the output at

4.00mA.

Reset the span a second time.

Enter the calibration mode by pressing the UP & DOWN buttons together for 1 second and press the UP button for 1 second to set the output at 0.00 mA.

4.5.8Jumper Switch Settings

The jumper switches are located on the top of the electronics module and can be set up as follows (Figure 4.7).

4.5.8.1ALARM (left jumper)

Placing the jumper to the lower position causes the output to go to 21.00 mA when there is a loss of signal or trans- mitter malfunction. Placing the jumper to the upper position causes the output to go to 3.62 mA when there is a loss of signal or transmitter malfunction.

Note: For the change to go into effect transmitter power must be cycled OFF and ON.

The alarm output works in conjunction with the ALD setting accessed from the configuration (CFG) menu. The out- put will go to alarm state only if there is a loss of signal that lasts at least the duration of the alarm delay. The alarm delay default value is two (2) seconds. For instance the output will hold the last measured value if there is a loss of signal lasting less than two (2) seconds and will go into the alarm condition if the loss signal exceeds two (2) sec- onds.

4.5.8.2 WRITE PROTECT (right jumper)

When the jumper is in the lower position the transmitter configuration cannot be changed manually or with a hand- held communicator (Figure 4.7).
