4.2. Basic Switching Functions
Positions 6, 7 and 8 of switch DIL1 allow selecting the following functions:
DIL 1
DIL 1
6
OFF: Standstill detection without post-trigger
function (see clarification below)
ON: Standstill detection with post-trigger function
(see clarification below)
7
OFF: Relay 2 and Out 2 to signal the opposite
direction of the Rel1/Out1 indication
ON: Relay 2 and Out 2 to signal zero motion
(standstill)
8
OFF: Upon detection of standstill, the
direction signal is cleared (no indication)
ON: Upon detection of standstill, the information of
the last actual direction remains active
The subsequent drawing explains the difference between "post trigger function on" and
"post trigger function off".

= Standstill signal OFF = Standstill signal ON
In order to get a standstill signal at all, the time distance between two positive edges must
become greater than the setting "T".
 Case (1) shows the post-trigger on. The standstill signal immediately switches off again
when another active edge is detected (no matter after which time). In this case, during
slow-down of the machine, the output and the relay might therefore produce multiple on-
off cycles before the standstill signal becomes stationary. However this method could be
considered as "more safe", because it would detect any motion, no matter how slow it is.
 Case (2) shows the post-trigger off. After the standstill signal has switched on, it will
remain on and only switch off again after two subsequent edges have been detected
where the time distance was less than T.
