Preparation for Operation 
Before switching on, check the following: 
✓  Ultra 5 is mounted correctly and is in a ‘safe’ area. 
✓  The power supply is correctly installed. 
✓  The voltage selector switch is in the correct position. 
✓  The relays are connected correctly. 
Maintenance 
There are no user serviceable parts inside Ultra 5, except the mains fuse. If 
you  experience  any  problems  with  the  unit,  then  please  contact  Pulsar 
Process Measurement for advice. 
To clean the equipment, wipe with a damp cloth. Do not use any solvents on 
the enclosure. 
Important Information 
The unique DATEM software comes into operation as soon as power is 
applied, and is designed to monitor a moving level or target with the 
transducer in a fixed position. 
If, after any period of use, it should become necessary to move the 
transducer, for any reason, from its original operating position, switch off 
the Ultra 5, before proceeding, to prevent any undesirable updates to the 
DATEM trace. If after moving the transducer the reading is not as expected, 
please refer to Chapter 9 Troubleshooting.
