Proportional
cycle
 
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.
Contact 
output
The shorter the proportional cycle, the ner the control. However, shorter proportional cycles 
also shorten the lifespan of the contact points and operating device. Keep a balance between 
controllability and controller lifespan when adjusting the proportional cycles.
Approx.: 30 sec
SSR drive 
output
Because there are no mechanical parts, use a short proportional cycle if the operating device is 
working properly.
Approx.: 1 or 2 seconds
 
The proportional cycle for the current output is same as the blinking cycle of OUT 
indicator (approximately 1 second).
