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
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
Right side view
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
1. The temperature range selector switch is factory-set to "0." With a temperature range, such as 50 to 150C, 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 50C is -50 to 60C. For other temperature range settings it is the full scale 10%.

E5CS-X
Temperature Indication Switching Key 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.

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.

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 3.75C per second with a full scale of 100C). 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 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. Example Main display Temperature measured by sensor 100C 100C 100C

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.
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.

Error Messages
E5CS-X
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 (1) Temperature has risen above set temperature range. (2) Thermistor has been short-circuited. (1) Temperature has fallen below set temperature range. (2) Thermistor has broken. (1) Failure has occurred in thermocouple or platinum resistance thermometer. (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. (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) 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. OFF Control output OFF during heating (reverse) ON during cooling (normal) ON during heating (reverse) OFF during cooling (normal) OFF
Note:
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.

Dimensions
Note: All units are in millimeters unless otherwise indicated.
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.

Precautions
Mounting
All Temperature Controllers in the E5CS-X Series conform to DIN43700 standard. The recommended panel thickness is 1 to 4 mm. 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.
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.
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.
