The j indicator lights in green if the deviation is within ±1% of the full scale. Main Display Sequentially displays the present temperature, set temperature, and an alarm value (in that order) each time the temperature indication switching ( ) key is pressed. Alarm Output Operation Indicator Lights when the alarm output relay is energized. Mode Indicator SP lights while the set temperature is displayed on the main display, and AL lights while an alarm value is being displayed. Protection Key When program protection is selected using the internal DIP switch, the upward and downward setting keys are locked. However, authorized personnel may change values using the upward and downward setting keys by holding down hidden protection key. Control Output Indicator Lights while the control output is being produced. Upward Setting Key When pressed, increases the set temperature/alarm value. Successively increases the value when held down. Temperature Indication Switching Key Each time pressed, changes the value displayed on the main display in the following sequence. Downward Setting Key When pressed, decreases the set temperature/alarm value. Successively decreases the value when held down. 5 E5CS-X E5CS-X Operation Temperature Setting Press the temperature indication switching key until the SP indicator lights. Then set the desired temperature value using the upward and downward setting keys. Alarm Setting Press the temperature indication switching key until the AL indicator lights. Then set the desired alarm value in units of °C or °F. If the present temperature reaches the set alarm value, alarm output will be enabled. Sensor Failure The error message “FFF” or “– – –” will appear on the main display if the temperature sensor, such as the thermocouple or platinum resistance thermometer, short-circuits or breaks. (Refer to Error Messages for details of the messages displayed.) Note: Neither the set alarm value is displayed nor the AL indicator lights with the internal alarm mode selector switch set to 0 or 9. The alarm mode selector switch is provided inside the housing, and is positioned differently on each model. Function Setting The various functions of the Temperature Controller are set using the switches on the internal mechanism. To gain access to these switches, the internal mechanism must be first drawn out from the housing. Push the tab on the underside of the housing, and pull out the mechanism. The procedures for making actual settings are given below. Setting the Temperature Range Set the desired temperature range by using the temperature range selector switch (“Set no.” setting in the tables below). 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 Right side view Do not set the selector switch to “9.” Doing so will result in the error message “FFF” or “– – –” being displayed. Note: 1. 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. Conversely, if the temperature range is changed from one in which the temperature can be set in 1° units to a range of 0.0 to 50.0 or 0.0 to 99.9, the unit is decreased to 1/10 of the original unit. 2. The display can indicate temperatures 10% beyond each of the set ranges. Thermistor Type Temperature unit (C° or F°), where a choice is available, is selected using pin 6 of the internal DIP switch which is also used for other settings, such as the control mode and sensor compensation. Note: Internal DIP switch Left side view 6 1. The temperature range selector switch is factory-set to “0.” With a temperature range, such as 50° to 150°C, that exceeds the setting range, the indication unit is automatically adjusted to the minimum value. The set temperature is displayed when power is turned ON. 2. The temperature range that can actually be indicated for a set temperature range of –50° to 50°C is –50° to 60°C. For other temperature range settings it is the full scale ±10%. E5CS-X E5CS-X Temperature Indication Switching Key Setting the Alarm Mode If the set temperature is shifted outside the temperature range as a result of changing the range, the set temperature is displayed. It is then automatically changed to the maximum or minimum vale of the newly set range. If the alarm value is shifted outside the temperature range as a result of changing the range, it is automatically changed to the maximum value of the newly set range. If the alarm mode selector switch is set to “0” or “9”, no alarm value is displayed. On models without alarms, no alarm value is displayed. The desired alarm mode can be chosen from one of the eight alarm modes using the alarm mode selector switch as shown below. Switch setting 0, 9 No alarm function 1 Upper- and lower-limit alarms 2 Upper-limit alarm 3 Lower-limit alarm 4 Upper- and lower-limit range alarm 5 Upper- and lower-limit alarms with standby sequence (see note) 6 Upper-limit alarm with standby sequence (see note) 7 Lower-limit alarm with standby sequence (see note) 8 Absolute-value alarm DIP Switch Settings The control mode and other settings are selected using the internal DIP switch as shown below. ON ON P Function Protect X P 1 2 3 4 5 6 X 1 2 3 4 5 6 Mode Alarm output OFF ON OFF --- Not used Note: Control mode PID ON ON/OFF OFF Proportional period 2s ON 20 s OFF Control output Normal ON Reverse OFF Input shift Setting enabled ON Setting disabled OFF The selector switch is factory-set to “2.” The triangular mark Y indicates the set temperature. X denotes alarm values. 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. Temperature sensor standard DIN ON JIS OFF Scale indicator (selectable) °F ON °C OFF Alarm output set with standby sequence will operate in the way shown below when the temperature drops below the upper-limit. 7 E5CS-X 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. ON ON Set pin 3 to ON when the Temperature Controller is used to control a cooling device, such as a freezer. ON P 1 X 2 3 4 5 ON P 6 X 1 2 3 4 5 6 Pin 1 OFF: Temperature Controller performs ON/OFF. ON Control output Control output ON OFF OFF Set temperature Set temperature PID Control Set pin 1 of the internal DIP switch to ON to make the Temperature Controller perform PID control. Follow the steps described below. ON ON 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 P 1 X 2 3 4 5 ON 6 Pin 1 ON: Temperature Controller performs PID control. P 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. ON 1 X 2 3 4 5 6 ON Reverse output OFF Set temperature Conversely, if the Temperature Controller is used to control a cooling device such as a freezer, set pin 3 to ON. ON ON P 1 X 2 3 4 5 ON 6 ON P Control output X 1 2 3 4 5 6 OFF 20 seconds ON Normal output 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 X 1 ON OFF 2 seconds 8 2 3 4 5 6 OFF Set temperature 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. E5CS-X 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. This powerful feature can be used for “fine tuning” compensation, while leaving the set temperature unaffected. The input shift function is activated by setting pin 4 of the internal DIP switch to ON. ON Example Main display (without shift) ON (offset by +9°C) (offset by –16°C) P X 1 2 3 4 5 6 This allows the setting of the temperature shift value. Press the tem) key repeatedly until “H 0” (in this perature indication switching ( case, indicating a zero input shift) is displayed on the main display. Then set the input shift value by using the upward and downward setting keys. Temperature measured by sensor Temperature displayed 100°C 100°C 100°C 109°C 100°C 84°C The input shift value can be set within a range of –99 to 99, except with a 0.0 to 99.9 platinum resistance thermometer, where the input shift narrows to a range of –9.9 to 9.9. When the desired shift has been entered, set pin 4 to OFF. The input shift value remains in memory. Consequently, if the input shift function is not needed, with pin 4 activated set the input shift value to 0. Sensor Failure Operation Thermocouple Type Condition Display Break in sensor Control output OFF blinks Note: When the input is short-circuited, the room temperature is displayed. Platinum Resistance Thermometer Type Condition Display Break in sensor Control output OFF blinks OFF blinks Disconnection of two or three wires blinks Short-circuit OFF OFF blinks Note: The resistance of the platinum resistance thermometer is 100 Ω at 0°C. It increases to about 140 Ω at 100°C. Thermistor Type Condition Display Control output Break in sensor ON during heating (reverse) OFF during cooling (normal) Short-circuit ON during heating (reverse) OFF during cooling (normal) 9 E5CS-X E5CS-X Error Messages The Temperature Controller is provided with self-diagnostic functions, and will display the following error messages if an error occurs. Message FFF ––– FFF (blinks) (see note 1) Cause Control output (1) Temperature has risen above set temperature range. OFF during heating (reverse) (2) Thermistor has been short-circuited. ON during cooling (normal) (1) Temperature has fallen below set temperature range. ON during heating (reverse) (2) Thermistor has broken. OFF during cooling (normal) (1) Failure has occurred in thermocouple or platinum resistance thermometer. OFF (2) Temperature has risen to a value much greater than the set temperature range. – – – (blinks) (see note 1) (1) Failure has occurred in platinum resistance thermometer. OFF (2) Polarities (positive and negative) of thermocouple have been reversed. (3) Temperature has fallen to a value much smaller than the set temperature range. E11 or E33 (see note 1) Note: Memory failure (E11) or A/D converter failure (E33) has occurred. Temperature Controller must be repaired if normal operation is not restored by turning power OFF once and ON again. Both control output and alarm output are OFF. 1. The key operations are disabled. 2. The models with alarm output produce alarm output according to the alarm output setting when the message “FFF” is displayed (or blinks), indicating that the temperature has risen above the set temperature range. Similarly, the alarm output is produced when the message ”–” is displayed (or blinks), indicating that the temperature has fallen below the set temperature range.

Panel cutout Note: 1. The recommended panel thickness is 1 to 4 mm. 2. The Temperature Controller is contained in a mounting bracket, so close side-by-side Temperature Controller mounting is possible. Provide a center-tocenter distance of at least 60 mm between two adjacent Temperature Controllers. 11 E5CS-X E5CS-X Precautions Mounting All Temperature Controllers in the E5CS-X Series conform to DIN43700 standard. The recommended panel thickness is 1 to 4 mm. Flush Mounting Insert the Temperature Controller, back end first, into the hole of the mounting panel. 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. or high temperatures. Separate the Temperature Controller from equipment that generates strong, high-frequency noise such as high-frequency welders. Connection Examples Solderless Terminal Use M3.5 solderless terminals with the Temperature Controller’s M3.5 self-rising pressure plate screws. 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. Use the specified compensating conductors for the thermocouple type Temperature Controllers. Use lead wires with a small resistance for the Platinum resistance thermometer type Temperature Controllers. Sequence Circuit Environment Do not install the Temperature Controller in locations subject to dust or corrosive gases. Do not install the Temperature Controller in locations subject to heavy vibrations or shocks, splashes of water or oil, Several seconds are required until the relay is turned ON after power is supplied to the Temperature Controller. Therefore, take this time lag into consideration when designing a sequence circuit which incorporates the Temperature Controller. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
