TABLE 5-1 ERROR MESSAGES
| The temperature sensor in the pressure measurement system measures the
temperature of the pressure manifold. At a temperature greater than 60°C the sensor
triggers an overheat fault. In measure mode, the display flashes between the normal
aim/measure screen and "Ps1 (or Ps2) Sensor Outside Calibrated Range". In control
mode, the display shows "CONTROL HALTED" the system stops controlling and switches
off the pumps. When the sensor detects a temperature of 55°C the display stops flashing.
| Before re-entering control mode check the air vents for obstructions.
| If this overheat fault happens. To re-enter control mode press LEAK MEASURE/CONTROL
twice.
