5 On-site maintenance
5.1. Weekly check preventive maintenance
Before making any preventive maintenance, switch the CU in manual mode (see part
3.7).
Here is a procedure that should be done every week in order to prevent the occurrence
of measurement, electronic or mechanical problems on the photometer. If correctly
done this procedure will avoid most of the problems that may occur:
1. Check all the connections, especially the ones on the battery (rust). Check
the sensor head cable. Check that the AZ and ZN cables are not wrapped
around the robot.
2. Check that the communication between the acquisition PC and the
photometer is still OK. If used, check that the satellite transmitter is still
running and does not have any errors by checking the led status.
If a problem is encountered, please refer to the troubleshooting part.
3. Check that the wet sensor functions correctly. Clean it lightly with
demineralized water and a non-abrasive tissue.
→
Go in the MEASURES menu and look at wetting parameter. (See part 3.4)
If wet,
“wet” is displayed, if not “dry” is displayed. In order to test the sensor if
it is not raining, wet it with water and wait around 20s, the value of wetting should
go from
“dry” to “wet”.
If a problem is encountered, please refer to the troubleshooting part.
4. Check that the robot is correctly levelled
→
Check that the level spirit of the robot is well centered.
If not, please check step 18 of the installation part to solve the problem.
5. Check the voltage of external batteries and the DCP battery if used
→
Check the photometer external battery measuring the voltage of the battery
terminals. The voltage should be over 12 Volts.
→
Same process for the DCP battery if used
Check the batteries general state. There must be no rust, leak and so on.
