12. Serial output
The IEV valve driver has an RS485 or TTL serial output (only 1 of the 2 outputs can be used) for the
following possible uses:
• connection to a Personal computer: the configuration parameters of the driver can be
programmed via Wizmate Prog Tool kit
• XWEB system connection to supervise the operation of the valve driver
• connection to a third party supervision system; the valve driver has Modbus RTU protocol
inside, with which the operating data can be read
13. Maximum power allowed
The IEV valve driver can control different types of motorised valves. The following table shows the
maximum current values that the windings of the valves can absorb.
Select the transformer that is suitable for the application on the basis of that shown in the table. The
type of Dixell transformer to use is indicated for every operating mode.
Do not disconnect or connect a valve to the IEV driver when it is connected to the power supply;
the connection or disconnection of the valve must always be done when the IEV driver is not
connected to power supply (IEV driver can be damaged).
NOTE:
Carefully read the technical manual supplied by the manufacturer of the valve body before using
the driver in order to prevent changing the data provided by the manufacturers of the valves,
and verify that the required currents are lower than those shown in the table below in order to
prevent damaging the control module.
