Description PRESSURE ERROR The unit has detected a problem with one of the internal pressure transducers. OVER PRESSURE A pressure greater than 550 mmHg has been detected. This error can occur during inflation if the hose is kinked or the cuff is occluded at the port. UNDER PRESSURE The unit has detected a problem with an internal pressure transducer or a vacuum has been applied to the cuff port. VOLTAGE LIMIT The unit has detected that an internal system voltage is not within allowable limits REFERENCE VOLTAGE LIMIT The unit has detected that an internal reference voltage is not within allowable limits VALVE/PUMP OPERATION The unit has detected improper activation of the pump or valve. This error may also indicate a failure of the pump, valve or pneumatic control circuits. SYSTEM ERROR The unit has detected an internal microcontroller error during operation SAFETY CIRCUIT TEST The unit has detected a problem with the safety monitoring circuitry during power on testing. PNEUNMATIC CONTROL The unit has detected a problem with the pump, valve, or pneumatic control circuits during power on testing. SAFETY CIRCUIT WATCHDOG The unit has detected a microcontroller problem during operation. SYSTEM WATCHDOG The unit has detected a microcontroller problem during operation. ROM CHECKSUM The unit has detected a problem with internal program memory during the power on self test. PUMP OPERATION The unit continually monitors the pump for proper operation; this error indicates that the unit has detected a problem with the pump or internal pneumatic circuit.
