The active time of the output pulse is proportional to the value of the control output. With
100 % output the pulse is active for the complete cycle time, for example:
5 s 5 s
50 % Output
Cycle Time
= 10 s
Note. Applicable only if Output Type is Time Prop or Split Output (and one output is a relay
or a digital output) – see page 24.
The cycle time to be used with time proportioning outputs. 
For split outputs this setting applies to Output 1– see page 24.
The cycle time to be used with time proportioning outputs. 
For split outputs this setting applies to Output 2 – see page 24.
Note. Applicable only if Output Type is Split Output.
