Protection Warnings
ArmorStart LT supports fault warnings. Refer to the WarningStatus parameter
(param 17).
The following describes the warning conditions for 290D/291D units:
The following describes the warning conditions for 294D units:
Bit Number Bit Enumeration Description
0 OverloadWarning This warning is generated when the value of %ThermalUtilized (param n5)
becomes greater than the value of the OLWarningLevel parameter (param 69).
2 UnderPowerWarn This warning is generated when switched power dips below 19.2 V for more than 4 ms.
4 PhaseImbalWarn This warning is generated in firmware by monitoring the relative levels of the
three phase currents. When the % imbalance becomes greater than the hard
coded warning limit, the warning is generated.
7 JamWarning This warning is generated in firmware when RMS current is greater than the
JAMWarningLevel (param 73) after the JamInhibitTime (param 70) has expired.
9 UnderloadWarning This warning is generated in firmware when RMS current is less than the
ULWarningLevel (param 79) after the ULInhibitTime (param 76) has expired.
14 UnswitchedPwrWarn This warning is generated when unswitched power dips below 19.2 V for 4 ms.
15 ConfigWarning This warning is generated when parameter configuration values that are inconsistent
with certain device options are written. This warning may not be disabled.
Bit Number Bit Enumeration Description
2 UnderPowerWarn This warning is generated when switched power dips below 19.2 V for more than 4 ms.
6 DriveParamInit This warning is generated when a Full Control Module to Drive parameter sync is in
progress, either on power up, or after an internal comms loss has been remedied.
12 FanWarning This warning indicates that either the fan is running between 62% and 70% of
rated RPM or that the “kick start” was needed to turn on the fan.
14 UnswitchedPwrWarn This warning is generated when unswitched power dips below 19.2 V for 4 ms.
15 ConfigWarning This warning is generated when parameter configuration values that are inconsistent
with certain device options are written. This warning may not be disabled.
