OUT1 Proportional Cycles ,
OUT2 Proportional Cycles
When using contact output and SSR drive output with PV
input inside the proportional band, output will switch ON/
OFF at regular intervals.
These intervals are called proportional cycles. OUT1 and
OUT2 can be set separately.
• Range: 1 sec to 150 sec
There are different recommended settings for different types
of control output, as shown below.
Setting the Preset OUT1/OUT2 Values
Contact 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. Be sure to balance
control and controller lifespan when
adjusting the proportional cycles.
Approx.: 30 sec
SSR Drive Output Because there are no mechanical parts to
this controller, use a short proportional cycle
if the operating device is working properly.
Approx: 1 sec to 2 sec
Caution
• TC2 is only valid when there are dual outputs.
• It cannot be set for current output or voltage output.

Press the key, then use the keys to set
the limit to 60.
The proportional cycle for OUT1 is set to 60 seconds.

Press the key to confirm the setting.
5
Repeat steps 2-4 (excluding pressing and holding
the key) to set the proportional cycle for
OUT2.
