Page 11 Digital Controllers and the service life will decrease. In such a case, use forced cooling by fans or other means of air ventila- tion to cool down the Digital Controllers. When providing forced cooling, however, be careful not to cool down the terminals sections alone to avoid measurement errors.

Page 13: Precautions For Operation
When starting operation after the Digital Controller has warmed up, turn OFF the power and then turn it ON again at the same time as turning ON power for the load. (Instead of turning the Digital Controller OFF and ON again, switching from STOP mode to RUN mode can also be used.) Avoid using the Controller in places near a radio, television set, or wireless installing.

Page 117: Using Event Inputs
• Depending on the Controller, there are either two event inputs (event inputs 1 and 2 or 3 and 4) or four event inputs (event inputs 1 to 4). The number of event inputs that can be used varies. (Only the E5AN/EN-H has event inputs 3 and 4.)
Page 118 • Switching is possible between two banks (0 and 1) by setting the Bank Numbers Used parameter to 1. The default setting is 1 and does not need to be changed. Banks 0 and 1 are specified by the status of event input 1 or 3.
Page 119: Operation Commands Other Than Bank Selection
ON/OFF changes are detected for inputs of 50 ms or longer. (However, inputs of 250 ms or longer is determined using logic operation.) The functions are described in detail below. Event inputs 1 and 2 are taken as examples. When using event inputs 3 and 4, substitute event input 3 for event input 1 and event input 4 for event input 2.
Page 120 When the Event Input Assignment 1 or Event Input Assignment 2 parameter of the Simple is set to PRST (program start), the program will start when event input 1 or 2 turns ON. The program will be reset when the input turns OFF and the RUN/ Program Function STOP status will automatically switch to STOP mode.
Page 121: Setting The Sp Upper And Lower Limit Values
When WTPT (Setting Change Enable/Disable) is set for either the Event Input Change Enable/ Assignment 1 or Event Input Assignment 2 parameter, the setting change will be disabled when event input 1 or 2 turns ON and will be enabled when the Disable input turns OFF.

During the SP ramp, control will be performed not for the specified set point but rather for the set point restricted by the rate of change set for the SP ramp function.
Page 124 STOP to RUN mode, the process value reaches the set point using the SP ramp function in the same way as when the set point is changed. In this case, operation is carried out with the process value treated as the set point before the change was made.
Page 125: Moving To The Advanced Function Setting Level
The operation of alarms during SP ramp operation depends on whether Ramp Operation alarms are set to be based on the ramp set point or the target set point (refer to the following diagrams). The set point to be used is set in the Alarm SP Selection parameter.

Page 354 (2) Initialized to SP upper and lower limits. (3) Clamped by SP upper and lower limits. (4) Initialized only when the input type is changed to analog input when RT turns ON. The defaults are as follows: RT: OFF (5) Initialization is performed as shown below according to the transfer output type setting. The initial- ization differs depending on the changed parameter and the output type setting.
Page 355 Appendix (11) Initialized to 4.0 for close control and to 2.0 for floating control. (12) If the ST is changed to ON, the SP Mode will be initialized to LSP and the remote SP function will be disabled. (13) If the remote SP function is disabled, the SP Mode will be initialized to LSP.
