Theory of Operation
The error output at the remote connector provides a contact closure (potential
free open collector maximum load 35 V DC/50 mA) as long as the error
condition is active. The error condition is set (closed) when the status light
shows the error condition (red).
The continuous mode overwrites all other operation modes of the degasser.
When activated (switch SW1 on the electronic board or via the auxiliary cable)
the vacuum pump is forced into continuous mode and is turned on as long as
the degasser is switched ON.
