12.1 Introduction
This chapter explains several operations that may be required during commissioning. The user should work
throughFirstTimeSwitchOn,UserCongurationandCongureDeviceIdenticationInformation,before
selectingfurtheroperationsasrequiredbythespecicinstallation.
First Time Switch On
Checks that are required on rst power up
User Conguration
How to change settings from the default values: -
Change the Password – How to change the password for Level 1 access
Congure HART
®
Operation during Fault - How to change the Fault
output level to 1 mA so that HART
®
will operate during Fault
Set the Time and Date - How to adjust the real time clock to local time
Congure Warning, Inhibit and Overrange Signal Levels - How to
change the signal levels from the default settings
Congure Device Identication Information
How to set text elds that may be useful for device identication
Fix the 4-20 mA Output
How to force the mA output to set levels in order to calibrate the controller
or test the system
Test 4-20 mA Loop Integrity
How to check that there is sufcient compliance in the loop to signal alarm
and overrange
Calibrate the 4-20 mA Loop
How to calibrate the current output (note this is not a gas calibration)
Congure Internal Alarm Threshold
How to change the internal threshold used to simulate Alarm and log gas
events
Simulation
How to test the system by simulating Alarm, Warning and Fault conditions
Clear Faults or Warnings
How to clear faults or warnings that may be generated during
commissioning
Caution: After changing any parameter, poll the Searchpoint Optima Plus and verify that the received
value is correct.
