4.5.1 Voltage supply and external Enable signal
The Connexx control unit is supplied with 24 VAC, 15 W through a built-in transformer
.
The primary side of transformer is connected to 230 V 50/60 Hz supply voltage.
With an external Enable signal, the Connexx system can be enabled or blocked by a
superior system (wire jumper, terminal 20/21).
The product removal is enabled as soon as the main switch on the side is set to "ON" and
- optionally - the external Enable signal is connected.
The Enable signal for the metering pumps (PUMP enable) is output only when the lifting
vessel level has been reached and (optionally) the external Enable signal is connected.
