persists. This error can only be cleared by turning off the device
and then turning it on again.
EPROM Checksum Error - Check the integrity of the firmware.
This error usually occurs when the firmware is changed and can
be cleared with an initialization. (This is done by holding down
the “0” on the keypad while powering up the unit.
Warning: An initialization will also reset the communication
parameters, password, and PID control parameters.
NVRAM R/W Failure - The non-volatile RAM had an error. This
is a serious error usually requiring hardware replacement if it
persists. This error can only be cleared by turning the device off
and then turning it on again.
Thermocouple Burnout - The thermocouple junction is open.
Check interface connections, thermocouple, and/or wire.
A/D Failure - One of the A/D converters is not working correctly.
If slowly cycling the power does not clear the error, then a
hardware replacement is necessary.
Vcc Out of Tolerance - An internal power supply is operating
out of tolerance.
V- Out of Tolerance - An internal power supply is operating out
of tolerance.
V+ Out of Tolerance - An internal power supply is operating out
of tolerance.
Illegal Pointer - One of the configurable arrays is using an
invalid register.
NVRAM Checksum Error - A value in the non-volatile RAM was
changed without resetting the checksum. Performing any write
function, such as a setpoint or command change should reset
the error. If the system behaves erratically after receiving an
error, the NVRAM may have been corrupted and you should
reload the factory configuration table from the disk provided
using the StarTalk for Windows software.
Divide by Zero - The StarPac II unit attempted an illegal math
operation due to bad calibration or configuration settings.
Reload the factory configuration table from the disk provided,
using StarTalk for Windows software.
Alarm Mask - Allows the user to enable or disable individual alarm
functions.
Setpoint Deviation - The controller is unable to maintain the
process at the current setpoint. (Sensitivity is adjusted using
StarTalk software.)
Positioner Deviation - The positioner is unable to maintain the
valve position at the current command. (Sensitivity is adjusted
using StarTalk software.)
Trip Condition - The unit is in a trip condition of either loss of
command, low supply air or a low flow cutoff. (Use the
M
ODE /S TATUS menu selection to display the type of trip.)
