troubleshooting information.
Error Codes
DEFAULTS LOADED!
indicates that system has been reset to factory defaults due to a bad configuration file stored in non
volatile memory. User settings will need to be reset.
SEQUENCER INIT
indicates that sequencer settings have been cleared due to bad sequencer data file stored in nonvolatile
memory. Sequencer settings will need to be reset.
E1:REF.SPEED df
indicates that control is not able to read maximum frequency value from the motor drive input power,
which is used to calculate the actual % Flow. In such case, standard US value is used (60 Hz).
E2:VFD Stopped
indicates that motor drive is stopped, and should be running according to selected user mode. When
*MANUAL STOP* is selected, this message is not displayed.
E3:VFD Fault!
indicates that motor drive is in fault (in trip). Fault conditions can be caused by motor overload (over
temperature, over voltage, over current), or any other condition that causes motor drive to be inoperative such as motor stall or pump
jam. In such case, the cause of motor fault should be corrected first, and then “manual stop” procedure should be performed to reset
the drive and restore proper operation.
E4:VFD Timeout!
indicates that communication between motor drive and the system is corrupted or there is no connection.
In such case, power should be disconnected from controller, and RS485 connection cable should be observed and replaced if
necessary.
E5:UART CRC Err
indicates checksum errors during communication with motor drive. In such case, disconnect power from
control, and ensure that all electrical wiring, connections, and terminals are properly attached and connected.
E6:VFD EEPROM ER
indicates that internal Emerson EEPROM memory is corrupted. In such case, the Emerson drive will not
hold its predefined configuration upon power failure. The control sets this configuration every time it is powered up, so normal
operation is possible, but it is recommended to replace the Emerson drive.
CLOCK IS NOT SET
indicates that the Real Time Clock in the control is not set or is invalid. In such case, the unit will not
perform Timer or Sequencer functions until the RTC is set again by the user. This is an E7 error, however the “E7” part of the
message is not shown due to its length.
E8:Check SETUP!
indicates that default values for “% Flow” and “Time” for all modes were loaded as well as other
parameters upon configuration/setup error. Such an error may occur when the system is powered up for the first time. In such case,
operator should enter Setup menu (pressing and holding 3 and 4 buttons for more than 5 sec.) and check or modify all parameters.
Exiting setup clears this error. If this error occurs every time the system is turned on (upon “power on”), it means that nonvolatile
memory (EEPROM) is corrupted and the interface should be replaced.
E11:VFD OVERLOAD
indicates that Emerson drive is overloaded. This message is reported directly from the Emerson drive.
Usually in such condition the drive either reduces the output current which results in the pump operating at a slower speed or trips and
restarts.
E12:MAINS LOSS!
indicates that Emerson drive has detected power loss on its internal power BUS. This message may also
appear when mains power is lost and the unit is about to shut down automatically.
E13:LOAD LIMIT!
indicates that Emerson drive has reached its load limit defined in LOAD MENU. This is an indication
that the motor drive and the pump current configuration are working at its load limits.
E14:EXT.CTRL ERR
indicates that the control has lost communication connection with external control unit (Goldline Aqua
Logic).
