4 Operation
The ECODRY plus can be operated either manually or via an interface.
Switch the pump only on provided an exhaust line has been connected.
The exhaust of the pump must not be blocked or constricted. Never oper-
ate the pump with the seal-off stoppers in place blanking off the exhaust
port.
4.1 Manual Operation
For manual operation, connect the jumper supplied with the unit to the X1
interface.
Switch the pump on at the MAINS switch and wait for approximately two
seconds while the pump initialises. Now the pump can be started using the
start/stop switch (PUMP).
Following start-up, the pump requires a few seconds in order to reach its
rated frequency.
In this mode, the X104 interface can only be used for reading off operating
parameters.
4.2 Interfaces
4.2.1 X1 Control Interface
The pump can be incorporated within a plant control system by means of the
X1 control interface. To do this, set the start/stop (PUMP) switch to “1”. The
ECODRY plus can be started remotely by closing the pin 8 contact to pin 9
on the X1 interface. Opening the contact stops the unit.
In this mode, the X104 interface can only be used for reading off operational
parameters.
