6.5.2

Low-level protection and testing



−

Double signal tone sounds, if the bath liquid falls so

much that the heater is no longer covered with liquid

completely

1. The display shows LEVEL (low-level) and the fault

triangle is flashing

heating is switched off on both poles,

pump and refrigeration system are switched off by

the electronics.

2. Top up the bath

➾

Section 5.2 and reset with the key.

☞

−

If necessary repeat several times in case that the pump does not purge

immediately.

−

Testing at regular intervals by lowering the bath level. Place a hose on the pump

connector and pump some of the bath liquid into a suitable container.

−

Step 1 - 2 must follow.

−

Bath temperature during this test not below 0°C or higher than 50°C, otherwise

danger of burn injuries !

−

If there is any irregularity when testing the safety devices, switch off the unit

immediately and pull out the mains plug !

−

Have the unit checked by the LAUDA service or the local service organisation!
