Configuration & Calibration Configuration & Calibration Calibration procedures (continued) Pressure Sensor Calibration (CODE 17) An internal pressure sensor is used to detect downstream occlusions. This sensor requires calibration whenever a new sensor, Main PCB is fitted or if door is changed or removed. It is necessary when servicing a pump, to carry out an occlusion pressure test to verify that the sensor is calibrated correctly (see self test routine in Chapter 3 Routine Maintenance).

Troubleshooting Troubleshooting Alarm types Non Recoverable Alarms In this state the pump will stop the infusion and give an audible and visible warning to alert the user that a non recoverable alarm (registered on the pump as a Fatal alarm) has occurred. With the exception of a micro-controller (MCU) error or internal communications fault with the external EEPROM, each alarm condition is identified by a unique code, which is stored in the alarm history log each time an alarm occurs, to enable the qualified service engineer to trace the error condition.
