Connector X at SF inputs
SF inputs connected to connector x are set low. That is, the inputs carry a 'lo' signal.
Parameter inputs
At some of the inputs you do not apply any signals. You configure the relevant block values
instead. Examples:
● Par (Parameter):
This input will not be connected. Here, you set the relevant block parameters (times,
on/off thresholds etc.).
● No (Cam):
This input will not be connected. Here, you configure the time patterns.
● P (Priority):
This is an open input. Here, you define priorities and specify whether a message is to be
acknowledged in RUN.
4.3.2 Time response
Parameter T
At some of the SFs it is possible to configure a time value T. When you preset this time, note
that your input values are based on the timebase set:
Timebase _ _ : _ _
s (seconds) seconds :
1
/
100
seconds
m (minutes) minutes : seconds
h (hours) hours : minutes
