Control Top with Solenoid Valves
The control top with solenoid valves acts as a control top. During and after
SETUP it indicates the status of the process valve locally by coloured LEDs
under the illuminated dome so that it is visible over a long distance. The position
feedback signals are supplied to the user in one of the following ways, depending
on the communication method selected:
• 24V DC PNP switching output
• AS interface data bit
with the difference being that the solenoid valve integrated in the base is
operated in accordance with the control signals. Depending on the design of the
process valve, up to 3 solenoid valves can be installed in the control top.
An NO solenoid valve can be used as compressed air support for the actuator
spring (only 2 solenoid valve variants possible).
The control signals are given by the user's process control system or by
operating the solenoid valves manually. To do this, use a screwdriver to turn the
screw (S) from 0 to 1, see figure.
