Possible Cause
• One or more of the internal fans
are not working
• Airflow is impeded
• High ambient temperature
• Drive is in direct sunlight
• Airflow is impeded
• PT100 Select is set to "Enabled"
and no RTD device is connected
to the drive.
• Drives using the built-in
MultiDrive function are
configured with pressure sensor
types that do not match
• Drives using the built-in
MultiDrive function have
firmware versions that are not
matched
• Improper MultiDrive cable
connection
• MultiDrive cable is damaged
Corrective Action
• Check fan connections to the Control Board.
• Fan blocked or inoperable, ambient above 104 °F (40 °C), direct
sunlight, air flow channel blocked
• Replace internal stirring fans or relocate drive as necessary
• Remove debris from fan intake/exhaust
• The drive has exceeded max rated internal temperature of
176 °F (80 °C), and needs to drop below 167 °F (75 °C) to restart
• Replace fan or relocate drive as necessary
• Remove debris from fan intake/exhaust
• Switch PT100 Select to "Disabled"
• Connect the RTD device to the drive
• Drives using the built-in MultiDrive function must have
matching pressure sensor types, either a traditional pressure
sensor or a pressure transducer.
• If both drives are configured with a pressure transducer, the
transducers must both be PSI type or bar type.
• Firmware version of one or more drives must be updated to a
matching firmware version using the SubDrive Connect Plus
mobile app.
• Check MultiDrive cable connections
• Replace MultiDrive cable
• Check dip switch setting for terminating resistor.
