Pulsafeeder Pulsar ECA NEMA4X - Manual (Page 26)

• Press and hold the BLACK pushbutton
• Apply power to the ECA.
• A mechanical zero calibration routine will begin. The routine begins when the motor
internal to the ECA starts motion looking for the zero position. Once the ECA
begins the routine you may release the pushbutton.
• The calibration routine is complete when the motor reaches the zero position and
the rotor locks for approximately 30 seconds. Zero calibration ends when the motor
stops running. .
• Remove Power to the ECA. Replace the cover (see Section Cover Re-
installation) and return power to the ECA.
9.1 Factory Re-initialization
T HIS PROCEDURE REQUIRES REMOVAL OF THE ENCLOSURE COVER . T HIS SHOULD BE DONE ONLY IF
THE AREA IS KNOWN TO BE SAFE FOR ELECTRONIC WORK .
A Factory Re-initialization restores all EEPROM calibration settings and mode settings to their
factory default values and is typically not required. The user also needs to keep in mind that
once the Factory Re-Initialization is performed, all user calibrations are erased. This procedure
should be performed only if the user has reason to believe that the internal ECA memory has
become corrupted. Memory Corruption usually manifests itself with inconsistent or erratic
operation. A number of factors could cause memory value corruption including:
1. Disregard of electrostatic precautions during installation,
2. Improper wiring,
3. Voltage surges, spikes, etc.
The pump MUST be running during this process to ensure an accurate zero position is
obtained. Therefore you MUST ensure it is safe to operate the pump during the
procedure.
• Verify that power to the ECA is off.
• Remove the enclosure cover.
• Press and hold both black and white pushbuttons while applying power to the ECA.
• Release the CAL pushbuttons and the unit is restored to the factory default settings.
• The unit will automatically perform a new mechanical zero calibration as part of the
Factory Re-Initialization routine.
• Perform any additional calibration procedures as required.
• Remove Power to the ECA. Replace the cover and return power to the ECA.
10. DIAGNOSTICS
10.1 Trouble Code Reporting
The ECA is designed to be as fault-tolerant and self-recovering as possible. When the ECA
encounters an abnormal condition, a trouble code is indicated by blinking CAL LED’s located on
the ECA main board, internal to the enclosure, as follows:
• Both LED’s will blink once.
• The Cal Input LED will blink a number of times to indicate the first trouble code digit.
