4.
Wait at least 5 seconds after starting the programming function before
activating the external solenoid valve and keeping it activated until the
process valve has reliably reached its actuated end position.
5.
Deactivate the solenoid valve. During this period, the illuminated dome is lit
red.
®
After completion of end position programming, the colours in the
illuminated dome change cyclically. Here you can select switching point
tolerances and attenuations which deviate from the factory setting, see .
®
If no selection is made within 30 seconds, the setting last selected is
automatically adopted. The process valve moves to the non-actuated
position, which is visualized by a steady light in the selected colour.
®
The control top is activated.
Hint!
When the colours are swapped, the feedback signals are also
swapped!
Checking the Control Top
Carry out the following steps:
1. Activate and deactivate the external solenoid valve in order to check the
proper function of the T.VIS feedback signals.
®
This completes commissioning.
7.3 Commissioning – Control Top with Solenoid Valves
Activating the Control Top
Once the control top has been properly mounted on the valve and the electrical
connections have been established correctly, commissioning can be carried out.
Since the T.VIS A-15 detects its solenoid valve fitting and therefore requires
corresponding process valve conditions, the so-called special default must
selected prior to SETUP in the event of a different.
Notice
Solenoid valve Y3 for the main stroke of an external process
valve is connected.
The main stroke of the external process valve is briefly activated during the
SETUP.
► Only carry out the SETUP when the pipe is empty.
Carry out the following steps:
1. Switch on the control air supply.
2. Check the valve function by activating the solenoid valves:
®
Switch on the solenoid valves in the order Y1, Y2 and Y3 (if fitted) using
the manual operating element on the solenoid valve: Use a screwdriver to
turn the screw (S) 0 in direction 1.
