[. . . ] The above settings, however, can be easily changed using the internal DIP switch. For details on the DIP switch settings, refer to Function Setting. 2 E5CS-X Accessories (Order Separately) Protective Cover Y92A-48 The protective cover protects the front panel, particularly the setting section, against dust, dirt, and water drip. It also prevents the set values from being altered due to accidental contact with the setting keys.

[. . . ] Eight or nine temperature ranges can be selected depending on the model. Thermocouple Type The display can indicate temperatures 10% beyond each of the set ranges. Platinum Resistance Thermometer Type Select the desired temperature range using the temperature range selector switch (rotary DIP type). Eight or nine temperature ranges can be selected depending on the model. The set temperature is automatically changed when the temperature range is changed. Be sure to confirm the set temperature. Temperature range selector switch Alarm mode selector switch Do not set the selector switch to "9. " Doing so will result in the error message "FFF" or "­ ­ ­" being displayed. The unit in which the temperature can be set is multiplied by 10 when the temperature range is changed from 0. 0 to 50. 0 or 0. 0 to 99. 9 to a range in which the temperature can be set in 1° units. 5 ON ON 6 P Function Protect X P ON OFF 1 X 2 1 3 2 4 3 5 4 6 5 6 7 8 --Control mode Proportional period Control output Input shift PID ON/OFF 2s 20 s Normal Reverse Setting enabled Setting disabled Temperature sensor standard Scale indicator (selectable) DIN JIS °F °C Not used ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF Note: The selector switch is factory-set to "2. " The triangular mark Y indicates the set temperature. Y denotes the set value value within the temperature range. Operation of Standby Sequence Alarm output set with standby sequence will operate in the way shown below when the temperature rises above the upper-limit. Alarm output set with standby sequence will operate in the way shown below when the temperature drops below the upper-limit. 7 E5CS-X Control Mode Selection ON/OFF Control Pin 1 of the internal DIP switch is factory-set to OFF, so the Temperature Controller performs ON/OFF control. E5CS-X Set pin 3 to ON when the Temperature Controller is used to control a cooling device, such as a freezer. ON ON ON ON P X 1 2 3 4 5 6 P X ON 1 2 3 4 5 6 Pin 1 OFF: Temperature Controller performs ON/OFF. ON OFF Set temperature Control output OFF Set temperature Control output PID Control Set pin 1 of the internal DIP switch to ON to make the Temperature Controller perform PID control. Determining Control Output Operation If the Temperature Controller is used to control a heater, the control output can be set to perform reverse (inverted) operation. Set pin 3 of the control output mode selector switch to OFF. ON ON ON P X 1 2 3 4 5 6 Pin 1 ON: Temperature Controller performs PID control. ON P X ON 1 2 3 4 5 6 Determining Proportional Period Set pin 2 of the DIP switch to OFF to select a proportional period of 20 seconds. This is used when PID control is performed with the relay output of the Temperature Controller, or when using an external relay or contactor. Reverse output OFF Set temperature ON ON Conversely, if the Temperature Controller is used to control a cooling device such as a freezer, set pin 3 to ON. ON P Control output OFF 20 seconds ON X ON 1 2 3 4 5 6 P X ON Normal output OFF Set temperature 1 2 3 4 5 6 When a quick response is required, set pin 2 to ON to select a proportional period of 2 seconds. Even when a solid-state relay (SSR) is used, only set the 2-second proportional period where quick response is essential. With a relay control output, a proportional period of 2 seconds will greatly reduce the service life of the relay. ON ON P Control output ON OFF X 1 2 3 4 5 6 2 seconds When power is first turned ON, the proportional band is set to 3%. The optimum proportional band, however, is automatically calculated and set within the range 3% to 20%, according to the changes in the temperature of the controlled system. This automatic adjustment of the proportional band is possible regardless of whether the controlled system is a heating or cooling system. When the power is turned OFF once, and then ON again, the control starts with the previous proportional band. A new proportional band, however, is automatically calculated and set. The calculation of the proportional band is not carried out, however, if the temperature of the controlled system changes at a rate faster than 7. 5% of the full scale per 2 seconds (e. g. , faster than 3. 75°C per second with a full scale of 100°C). In this case, the previously calculated and set proportional band is used. The Temperature Controller is provided with an overshoot prevention function that suppresses the second overshoot and those that follow to a level less than the initial overshoot. 8 E5CS-X Input Shift Function This function is used to shift the value displayed in the main display from the value actual measured by a desired amount. [. . . ] Mount the adapter by pushing it forward from the back of the Temperature Controller. Push the adapter as close as possible to the front panel of the Temperature Controller to eliminate the gap between them. Then, secure the adapter with screws as shown in the figure below. Solder-dipped Lead Wires Strip the lead wire 6 to 12 mm and carefully arrange the wire tip. Removal Loosen the screws on the adapter and push the hook open to remove the adapter. Do not tighten the terminal screw with excessive force. Input Sensor Connection Hook Screw The lead wires connecting the sensor to the Temperature Controller must be separated from power lines and load lines wherever possible, to prevent them from being induced by noise.
