While the programming routine runs automatically, the solenoid valves in
the control top are activated and deactivated, which causes the process
valve to automatically move to the positions in succession. During this
period, the illuminated dome is continuously lit red. After completion of end
position programming, the colours in the illuminated dome change
cyclically.
®
In deviation from the factory setting you can select switching point
tolerances, attenuations and the LEFF function (only if the valve is LEFF
compatible, i.e. double-seat valve with lifting actuator), see .
®
If 24/7 PMO valves (types M_O (06), M/2.0, MT/T_T (08) are used in
conjunction with the control top T.VIS A-15, the factory settings in the
control top may not be changed.
®
If no selection is made within 30 seconds, the setting last selected is
automatically adopted and visualized in accordance with the colours
selected.
®
The control top is activated.
Checking 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.
Carry out the following steps:
1. Activate the solenoid valves in succession via the PLC in order to check the
proper function of the T.VIS feedback signals.
®
This completes commissioning.
