In the Setting Display for the PID parameters, Displays can be arbitrarily switched using the Up, Down, Left or Right arrow key.
Page 58 6.4 Adjusting PID Manually Description Description and Tuning of Proportional Band The proportional band is defined as the amount of change in input (or deviation), as a percent of span, required to cause the control output to change from 0% to 100%. Because a narrower proportional band gives greater output change for any given deviation, it therefore also makes the control performance more susceptible to oscillation.
Page 59 6.4 Adjusting PID Manually Description and Tuning of Integral Time The integral action (I action) is a function that will automatically diminish the offset (steady-state deviation) that is inherently unavoidable with proportional action alone. The integral action continuously increases or decreases the output in proportion to the time integral of the deviation (the product of the deviation and the time that the deviation continues.) The integral action is normally used together with proportional action as proportional- plus-integral action (PI action).
Page 60 6.4 Adjusting PID Manually Description and Tuning of Derivative Time If the control object has a large time constant or dead time, the corrective action will be too slow with proportional action or proportional-plus-integral action alone, causing overshoot. However, even just sensing whether the deviation is on an increasing or a decreasing trend and adding some early corrective action can improve the controllability.
Page 61 6.4 Adjusting PID Manually Manual PID Tuning Procedure (1) In principle, auto-tuning must be used. (2) Tune PID parameters in the order of P, I, and D. Adjust a numeric slowly by observing the result, and keep notes of what the progress is. (3) Gradually reduce P from a larger value.

Page 96: Suppressing Overshoot (Super Function)
8.5 Suppressing Overshoot (Super Function) Description The Super function monitors the deviation for evidence that there is a danger of overshoot, and on sensing such danger automatically changes the setpoint temporarily to a somewhat lower value (sub-SP). Once the danger of overshoot appears diminished, the function returns the effective SP gradually to the true SP.

Page 100: Suppressing Integral Action (Anti-Reset Wind-Up)
8.7 Suppressing Integral Action (Anti-reset Wind-up) Description Where there is a large deviation at the start of the control operation, for example, integral outputs are accumulated and the PV exceeds the SP, thereby causing the output to overshoot. To avoid this, the controller provides an anti-reset wind-up function for suppressing an extreme integral output by stopping PID computations.
Page 101: Adjusting Auto-Tuning Operation
8.8 Adjusting Auto-tuning Operation Description Auto-tuning Type “Normal” of auto-tuning type requires a rapidly rising PID constant. This type is useful for processes that allow some overshooting. On the other hand, “stable” of auto-tuning type requires a slowly rising PID constant. Auto-tuning Output Limiter When executing auto-tuning, the control output high and low limits can be set.

Page 111: Setting Control Output Cycle Time
10.2 Setting Control Output Cycle Time Description Cycle time is the basic cycle period for a signal full cycle of ON/OFF operation for a relay or voltage pulse output. Reducing cycle time results in faster cycling and finer control. In contrast, reducing the ON/OFF period also reduces relay life. For relay output, set the control output cycle time to 30 to 200 seconds according to the process speed.
Page 112: Setting Limiter To Control Output
10.3 Setting Limiter to Control Output Description Control output high and low limits can be set to restrict the control output to the operation range between those limits.

Page 187 17.1 Installation Location Do not mount the instrument in the following locations: • Outdoors • Locations subject to direct sunlight, ultrared rays, ultraviolet rays, or close to a heater Install the instrument in a location with stable temperatures that remain close to an average temperature of 23°C.
Page 188: Mounting Method
17.2 Mounting Method WARNING Be sure to turn OFF the power supply to the controller before installing it on the panel to avoid an electric shock. Mounting the Instrument Main Unit Provide an instrumented panel steel sheet of 1 to 10 mm thickness. After opening the mounting hole on the panel, follow the procedures below to install the controller: Insert the controller into the opening from the front of the panel so that the terminal board on the rear is at the far side.
