Protections:
• Low Voltage Protection: Low Voltage Fault will be displayed when mains supply is lower  than %20 of nominal voltage
• High Voltage Protection: High Voltage Fault will be displayed when mains supply is higher than %20 of nominal voltage
• High Temperature Protection : Temperature Fault will be displayed when body temperature is higher than 80°C
• Phase Protection: Phase Fault will be displayed when one of the three phases of supply voltage is lost for three-phase drivers.
• Short Circuit Protection: Motor short circuit fault will be displayed when motor connection is short-circuited
• Minimum Pressure Protection: In case the system does not reach set pressure before set duration, pressure fault will be displayed  on screen but the system will not be blocked and the algorithm will try to reach set pressure for a few times more.
• Dry running protection with the help of floater
