Searchline Excel™ Plus / Searchline Excel™ Edge – Technical Manual
7.6.74–20 mA Loop Integrity Test
Test the 4–20mA loop integrity:
1. Force the receiver to output a known current.
2. Monitor the known current at the control room or with a multimeter inserted into the loop.
After the test is carried out, update the Installation Checklist and mark the appropriate box.
7.6.8Clear Historical Fault/Warning Log
1. Connect the Mobile Device to the receiver via Bluetooth.
2. Start the Honeywell Fixed Platform App.
3. Clear the historical fault/warning log in the App.
Current ACTIVE fault(s) will stop the instrument operation. These have to be diagnosed and cleared in order to re-establish
full operation..
7.6.9Customer Notified
Make sure that the relevant customer/operator is notified of the installation problem(s). Mark box accordingly.
7.6.10System Status
Upon leaving, note the Searchline Excel Plus or Searchline Excel Edge status, i.e., operational or non-operational.
7.6.11Installation Checks/Tests
Carry out installation checks/tests and fill out the subsequent Installation Checklist. Carefully read the safety warnings,
cautions and certification details in this manual. Ensure that they have been complied with, before and during
the installation.
In order to help Honeywell Analytics to provide efficient assistance/service in the event of problems, return the Checklist to
Honeywell Analytics or to their agent.
Declaring installation satisfactory
Only personnel fully trained by Honeywell Analytics or Honeywell Analytics authorised trainers can declare an installation
satisfactory.
Mark the YES box and sign the form if:
1. having completed the installation and testing, the instrument is operating correctly, and
2. in the trained installer’s opinion, the instrument should continue to operate reliably in this installation/operating
environment providing that nothing significant about the installation/environment is changed.
If the instrument is not operating correctly or there are aspects of the installation/operating environment which in
the trained installer’s opinion could or will result in unreliable operation, mark the NO box.
Reasons for declaring an installation unsatisfactory could include:
• excessive movement/vibration of instrument’s mounting,
• received signal levels too low,
• supply voltage too low,
• 4–20 mA loop integrity faults,
• unclearable active faults,
• any prevailing or probable condition which is known to unacceptably reduce reliability or functionality.
If Installation is unsatisfactory, state reasons
Briefly state the principal reasons why the installation is unsatisfactory, e.g.
• Instrument mounted on single scaffold pole,
• Excessive movement,
• Beam path obscured by pipes, insufficient received signal levels,
• Instrument overheated by intense sunlight.
