Pulsafeeder Pulsar ECA NEMA4X - Manual (Page 29)

10.3 Self-Test Mode
The ECA has a diagnostic test mode which can be used to verify performance and troubleshoot
problems. To initiate the self-test:
• Remove power from the ECA, and remove the top cover.
• Disconnect any field wires attached to J4, and connect Analog Out to Analog In.
(jumper J4-1 to J4-3 and J4-2 to J4-4).
• Press and hold the white Input Cal pushbutton.
• Apply power to the ECA and release white Input Cal pushbutton. The ECA will
enter the self-test mode and automatically perform the following tests:
Calibrates mechanical zero position
Drives to the 0% stroke position, testing the motor drive and the encoder. Both Cal
LED’s will blink if the zero calibration fails.
Pauses for 30 seconds, and then confirms that the Analog Output and the Analog Input
are correct. Sets trouble code 22 if analog ports do not agree.
Drives to the 100% stroke position, testing the motor drive and the encoder. Sets the
trouble code to 13 if the 100% position is not attainable.
Pauses for 30 seconds, and then confirms that the Analog Output and the Analog Input
are correct. Sets trouble code 23 if analog ports do not agree.
Confirms that the motor thermistor is reading in correct range. Sets trouble code 24 if
thermistor readings are outside specifications.
Sets trouble code 33 to indicate test passed.
Turn power off to the ECA, and remove the jumpers installed in step 2. Re-connect field
wires.
