6.1.1 Switch-over of feedback signals
The signals to the control can be switched over via the bridge
between the terminals 10, 11 and 12.
If a bridge is located between the terminals 10 and 11 (normal), the
signal is transferred from sensor 1
(closed valve position)
to input
DI0 of the control. The signal of sensor 2
(open valve position)
is
sent to input DI1.
In case of a bridge between terminals 11 and 12 (reverse), the
signal of sensor 1
(closed valve position)
is sent to input DI1
of the control. At input DO0, the signal of sensor 2
(open valve
position)
switched.
If there is no bridge between the terminals 10, 11 and 12, this will
lead to an error message.
The two LEDs
'valve open'
and
'valve closed'
will flash in this
case.
