List Of Lcp Errors - Trane TR150 Programming Manual

Troubleshooting
ALARM 126, Motor Rotating
High back EMF voltage. Stop the rotor of the PM motor.
WARNING 127, Back EMF too high
This warning only applies to PM motors. When the back
EMF is larger than 90%*U
does not fall to a normal level within 5 s, this warning
occurs.
WARNING 200, Fire Mode
4 4
Fire mode has been activated.

4.6 List of LCP Errors

LCP errors are not warnings or alarms. They do not affect the operation of the frequency converter. Illustration 4.1 shows an
LCP error on the LCP.

Error message
LCP comm. Lost
Key disabled
LCP copy failed
Data not compatible
Read only
Database busy
Parameter invalid
Exceeds limits
Motor is running
Not while running
Password rejected
WARNING 202, Fire Mode Limits Exceeded
Fire mode has suppressed 1 or more warranty-voiding
alarms.
ALARM 250, New Spare Part
The power or switch mode supply has been exchanged.
ALARM 251, New Type Code
The frequency converter has a new type code.
Communication between the LCP and the frequency converter is lost.
The LCP key is disabled. One of the LCP keys has been disabled in parameter group
0-4* LCP Keypad.
Data copy failure. This error occurs when data is copied from frequency converter to
LCP, or from LCP to frequency converter (parameter 0-50 LCP Copy).
LCP data incompatible. This error occurs when data is being copied from LCP to
frequency converter (parameter 0-50 LCP Copy). The typical reason is that data is
moved between frequency converter and LCP that have major software differences.
Parameter read only. An operation is issued via LCP to write a value to a parameter
that is read-only.
The parameter database of the frequency converter is busy.
The parameter value that is input via the LCP is invalid.
The parameter value that is input via the LCP exceeds limits.
The LCP copy operation cannot be performed when the frequency converter is
running.
The parameter cannot be changed while the frequency converter is running.
The password that is input via the LCP is incorrect.
