Description

External main switch with bypass function. In an emergency, the frequency inverter can be bypassed using the main switch, enabling 100% speed operation of connected fans. Zenec main switch for 1~ EC fans from the ETAvent and ECblue series with 100% function. EC fans are controlled via an external control signal, e.g. 0 – 10 V. If the control signal drops due to a technical defect, the Zenec can be used to manually switch the connected EC fan to 100 %. To do this, the EC fan must have the control possibility for the 100 % function. ETAvent fans and ECblue for agriculture normally have this function. In livestock farming in particular, this function is very important to ensure ventilation in the animal housing. In addition, the Zenec can supress the fault indication issued by an external device when the Zenec is switched to the “0” position.
