Typical Control
Examples
■ Wiring
Connect the input to terminal IN1 according to the input type, connect
the open side of the position proportional valve to OUT1, and connect
the closed side to OUT2.
When using the E5AR-PR4DF, wire as shown below.
When using floating control, there is no need to connect a potenti-
ometer (C, W, O) unless the amount of valve opening is being
monitored.
■ Settings
Select the value control type and perform floating control using
Position-proportional value with travel time* of 45 seconds. Set SP
ramp to change SP within a width of 10.0 °C / minute.
*Time from completely open to completely close.
The related setting data and settings are as follows:
Action = or-r: Reverse action (initial setting)
"Closed/Floating" = float: Floating
(initial setting)
Travel time = 45 sec
SP ramp time unit = m: min (initial setting)
SP ramp rise value = 10.0 (°C)
The travel time and SP ramp rise value are set in the following, and the
initial settings are used for all other parameters.
1. Turn on the power and then hold down the L key for at least 3 seconds to
move from "RUN level" to "Input initial setting level".
