h) Test the yellow terminal against all other terminals except the orange and violet ones.
i) Test the violet terminal against all other terminals except the yellow and orange ones.
There should be infinite resistance for each pair. If there is any resistance at all, there is a short between
terminals.
Postrequisites
To return to normal operation:
1. Plug the terminal blocks into the terminal board.
2. Replace the lid on the sensor junction box.
Important
When reassembling the meter components, be sure to grease all O-rings.
17.36 Using sensor simulation for troubleshooting
When sensor simulation is enabled, the transmitter reports user-specified values for basic process variables.
This allows you to reproduce various process conditions or to test the system.
You can use sensor simulation to help distinguish between legitimate process noise and externally caused
variation. For example, consider a receiving device that reports an unexpectedly erratic density value. If
sensor simulation is enabled and the observed density value does not match the simulated value, the source
of the problem is likely to be somewhere between the transmitter and the receiving device.
Sensor simulation requires an enhanced core and a communication device.
Important
When sensor simulation is active, the simulated value is used in all transmitter outputs and calculations,
including totals and inventories, volume flow calculations, and concentration calculations. Disable all
automatic functions related to the transmitter outputs and place the loop in manual operation. Do not enable
simulation mode unless your application can tolerate these effects, and be sure to disable simulation mode
when you have finished testing.
17.37 Check the printing
Procedure
1. Verify that the printer is powered.
2. Verify the physical connections.
3. Verify the network settings configuration.
4. Verify that the printer is online.
See the printer manual for descriptions of status LEDs.
5. If the printer is offline:
a) Check the paper.
b) Verify the paper cover is closed correctly.
