Safety features on the instrument
The HistoCore PEARL tissue processor is equipped with safety functions and with sophisticated
software control mechanisms. These ensure that the specimens remain undamaged in the event of a
power failure or other malfunction during the program and that the program is completed successfully.
2.3.1 Overpressure protection
•
When the power is switched off, the pressure air pump and valves default to a safe condition (retort
vented, no pressure generation).
•
In addition, there is a relief valve that vents all excess air pump output to atmosphere.
2.3.2 Overcurrent protection
Overcurrent conditions are protected against by the main fuse overcurrent protection.
2.3.3 Overheating protection
The heat limiter protects the instrument against the abnormally high temperature.
