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).
