Command Description
Ready The interface is ready for the next command.
Hold current output Hold the current output at the current output hold
value.
Clear all alarms Acknowledges, clear, and reset all alarms.
Start CAL cycle Begin a calibration cycle.
Hold current output at maximum
setting Hold the current output at the maximum output value.
Hold current output at minimum
setting Hold the current output at the minimum output value.
Clear ALL holds Clear all holds that are currently active.
Hold density at density hold mode
value Hold the density at the density hold mode value.
Hold current output at FAULT HIGH Hold the current output at the FAULT HIGH level.
Start system test Causes the unit to test the various types of memory,
the data integrity, and the signal processor. The system
performs an automatic test and verification function
every 10 minutes, and all user-entered data is double
stored and periodically cross-checked. Errors are
automatically corrected, and an alarm is activated
when an error is detected.
Use latest CAL value for CAL point
1 Use the latest CAL value as CAL point 1.
Select alternate time constant Switch to the alternate time constant
(TC_ALTERNATE).
Select primary time constant Switch to the primary time constant (TC_PRIMARY).
Erase all entries (EVERYTHING) Erase all configured data.
Restart without power cycling Restart the system without cycling power.
Erase all alarm action assignments Erase entries for alarm assignments to relays, current
output, etc.
Start standardization Begin a standardization cycle.
Hold current output at FAULT LOW Hold the current output at the FAULT LOW level.
Switch current out to alt/pri mode Switch the current output to alternate/primary mode.
Abort standardization Stop the currently running standardization cycle.
Erase protected NVRAM Erase NVRAM.
Refresh Refresh the data in the fieldbus interface.
