Internet: www.galltec-mela.de Product info sheet Condensation detector to prevent the building of condensed water FAS 250VAC Type Survey Type Contact type changeover contact with silver contacts changeover contact with gold contacts Technical Data The PCB module with Polyga® sensing element is arranged on a base plate so the sensing element is located in close proximity to the base plate. Given the protection of the enclosure, moisture close to the dew point can form on the inside. The base plate is in contact with the cooling pipe and transmits the cooling energy to the sensing element. The switching point can be adjusted on the inside. It is necessary to adjust the switching point to suit the ambient conditions. The microswitch switches a changeover contact at zero volt. The FAS does not require a supply voltage or auxiliary energy. Adjusting the switching point It is important to set the correct switching point for the system. A switching point which is set too high can cause condensation because the conditions of the measuring point are not always constant. The measuring point of the humidity controller should be selected to ensure that no condensation can form on or in the appliance. Tests have shown that good results are achieved at a switching point of 80%rh. The switching point can be set to suit the system. To do this, open the cover and adjust the switching point. applied directives / standards low-voltage directive 2014/35/EU EMC directive 2014/30/EU DIN EN 60730-1:2012-10 DIN EN 60730-2-13:2008-09 Notes on voltage The measurement location of the humidity controller should be selected such that there is no build-up of condensate on or in the device. There is a risk of voltage arcing in the event of water condensation on the microswitch or connecting terminals which might destroy the controller. In the event of water condensation. Particularly operating with a voltage higher than 48V may endanger people. The humidity controller should be used up to a maximum of 95%rh.

FAS 250VAC page 2 Connection diagram Dimensions diagram The electrical connection must only be carried out by properly qualified personnel. It is essential to ensure that the device is earthed via an accordingly marked earthing screw. If the rel. humidity (actual value) falls below the setpoint value, contact 1/4 opens and contact 1/2 closes.
