Cycle time of control output 1 (041)
[Description] –––––––––––––––––––––––––––––––––––––––––––––––––––––––
When using contact output and SSR drive output with PV input inside the
proportional band, output will switch between ON and OFF at regular intervals.
Setting range
1 to 150 sec
The following are the recommended settings for each control output.
●
The shorter the proportional cycle, the finer the control. However, shorter proportional cycles
also shorten the lifespan of the contact points and operating device. Keep a balance between
