Setting Output Specifications Section 3-5
For example, when the process value (PV) is lower than the set point (SP)
in a heating control system, the manipulated variable increases according
to the difference between the PV and SP. Accordingly, reverse operation is
used in a heating control system. Direct operation is used in a cooling con-
trol system, in which the operation is the opposite of a heating control sys-
tem.
• Direct/reverse operation is set in the Direct/Reverse Operation parameter
in the initial setting level. The default is or-r (reverse operation).
Operating Procedure In this example, the input type, temperature unit, direct/reverse operation, and
control period (heat) parameters are checked.
Input type = s (K thermocouple)
Temperature unit = c (°C)
Direct/reverse operation = or-r (reverse operation)
Control period (heat) = 20 (seconds)
3-5-3 Assigned Output Functions
• Function assignments can be changed by changing the settings for con-
trol and auxiliary output assignments.
• The default function assignments for each output are shown below.
Operation Level
1. Press the O Key for at least three seconds to move from the operation
level to the initial setting level.
Initial Setting Level
2. The input type is displayed. When the input type is being set for the first
time, s (K thermocouple) is set. To select a different sensor, press the U
or D Key.
3. Select the Temperature Unit parameter by pressing the M Key. The de-
fault is c (°C). To select f (°F), press the U Key.
4. Select the Control Period (Heating) parameter by pressing the M Key.
The default is 20.
5. Select the Direct/Reverse Operation parameter by pressing the M Key.
The default is or-r (reverse operation). To select or-d (direct opera-
tion), press the U Key.
Operation Level
6. To return to the operation level, press the O Key for at least one second.
