- Page 10 Description B) The alternating current trough the steam electrodes is brought via a short induction path to the BINDER humidity board. Loop between plug connectors L1 and L2. The exact setting of the maximum permissible current between the steam electrodes becomes adjusted via potentiometer R4 or R5 to set the switching point to 2A as limit for the current through the steam electrodes.
- Page 11 0V = no humidity demand 24V = steam production necessary The binary signal is taken there and gets via plug connector HLR + and – to the BINDER humidity board. The Binder Humidity Board switches +24V on plug connector SPS I 0.0 as message for the SPS that there is a humidity demand.

- Page 16 Service – documentation series KB/KBF Operate the unit until the required humidity is reached and allow to settle (cf. Point 10). When the unit has reached the required humidity, please allow it to continue running for approx. 0.5 hours - only then is the unit reliably adjusted and ready for calibration.

Chapter 4 Maintenance Cooled incubators and climatic chambers Binder’s cooled incubators and climatic chambers allow you to achieve constant conditions with a temperature capacity of 0.0°C to 99.9°C. Cooled incubators are used in biotechnology, medicine, the food industry, pharmaceutical and cosmetics industry, botany and zoology. - Page 19 Service – documentation series KB/KBF Cooled incubators and climatic chambers The contamination of the filter and the functionality of the electrovalve are checked. The functionality of the lye pump is checked by pumping out water. The water tank is removed and the seal on the support foot checked for ageing or wear. The water tank is dismantled and the electrodes examined for wear or deposits.

- Page 23 Service – documentation series KB/KBF Hot gas injection In the case of the KBF unit, hot gas injection with the PD2 and D2 controllers is a standard function. The humidity accuracy is influenced by the hot gas injection. When hot gas is injected into the dehumidification tube humidity is released, and therefore the humidity sensor registers a greater humidity at the time of injection.
- Page 24 Service – documentation series KB/KBF KBF function connection diagram Cold gas circuit The cold gas is pumped by the compressor towards the condenser. In the condenser the cold gas is cooled down, then it passes through the drier. In the drier humidity is removed from the cold gas. The Electro valve is controlled by the controller and is opened as the temperature demands, thus passing cold gas through the evaporator plate.
- Page 25 Service – documentation series KB/KBF Humidity controller SM On the controller’s main plate there are 2 plugs strips (E1/E2) which can be plugged onto the front-end plates. The front-end plated determine the type of signal that can be processed. E1 is in direction contacts and E2 is in direction front cover.
- Page 26 Service – documentation series KB/KBF Humidity control using a D2/PD2 controller and L3 humidity board. The controller receives a signal of 4 to20 mA from the humidity sensor measuring the humidity value in the oven. When more humidity is necessary, the controller will send a signal in the range of 3,5V to 7V to the humidity circuit board L3.
- Page 27 Service – documentation series KB/KBF KBF with PLC function connection diagram. Cooling fluid cycle. The cooling gas is pumped from the compressor to the condenser. In the condenser the cooling gas is cooled and liquefied, then it flows through the dryer. In the dryer the humidity in the cooling fluid is dried out.
