Tunze Osmolator Controller Part
2-10 Days
There are two sensors implemented into the TUNZE Osmolator 3155®, whereas an operating sensor is used to monitor the water level and a safety sensor to prevent an overfilling of the aquarium. The operating sensor scans the water surface, and triggers the controller if the water level falls below the preset water threshold. This switches on the metering pump, which then conveys a sufficient amount of water from the reservoir into the aquarium to replenish the evaporated water. After this process has concluded, the controller which is equipped with an electronic time monitoring, automatically switches off the metering pump. The operating sensor should fail due to technical reasons, the safety sensor will prevent an overfilling of the aquarium, and a signal tone will be emitted. If the metering pump runs longer than 10 minutes it will be shut off for safety reasons. Due to the high rate of evaporation in aquariums with more than 1,000l (264 USgal.) we recommend the use of the switched socket outlet 3150.11 (10) with the recirculation pump Silence 1073.02 or 1073.04 instead of the metering pump 5000.02. Light-emitting diodes (LEDs) on Controller 5017 When the controller is switched on, an automatic self-test is carried out causing all LEDs to light up for one second, also sounding a warning tone. Red LED “Too low” is flashing = metering pump had been operating for more than ten minutes and has been switched off. The normal water level has not been reached. Potential cause: Storage container is empty; the hose is soiled or kinked; the pump is defective; air in the pump; soiled, defective or unhooked operating sensor (2). Reset is possible by short disconnection from the mains. Yellow LED “Pump on” is lit = the connected metering pump (1) is operating. The LED is lit and the pump delivers for at least 15 seconds. Frequent switching is avoided in this way. Green LED „Level“ is lit = the operating sensor (2) has contact to water. If the operating sensor is without water for more than 3 seconds (LED off), the metering pump starts operating.
