Operation
J Settings Before Applying Power
Note: Always turn off the power supply to the temperature controller before changing any switch settings. Before applying power to the temperature controller, set the following selector switches to specify the temperature range, functions and alarm mode.
Temperature range selector switch Alarm mode selector switch Protection switch
Control mode selector switch
J Access to Internal Switches and Selectors
Push the tab on the underside of the front panel as you draw out the internal mechanism from the housing. The temperature range selector, and the alarm mode selector must all be set. A protection switch can also be set to protect settings. The following diagrams show the locations of these switches on the internal mechanism.

Right side view

Left side view
Select the desired temperature range by using the temperature range selector switch (rotary DIP type). The other rotary DIP switch is used to select one of eight alarm functions. Be sure the set temperature and alarm values are within the new range. Otherwise, the temperature controller automatically shifts these values to the maximum or minimum of the newly-set temperature range. The protection switch may be used in conjunction with the front panel hidden key to prevent unauthorized changes to temperature settings. The switch is ON when it is pushed inwards in the direction of the white arrow. The function selector switch is a 8-pin in-line DIP switch on the other side of the internal mechanism. Use it to select ON/OFF or PID control action, proportional period, control output, input shift function, temperature sensor input standard and scale indication for dual-scale temperature ranges.
J When All Functions Have Been Selected

To Set Temperature

Press the return key until the SP indicator lights. Then set the desired temperature value by using the Up and Down keys. Neither the set alarm value is displayed nor the AL indicator lights with the integral alarm mode setting switch set to 0 or 9. Be sure to check the alarm mode setting switch, located inside the housing, for proper setting.

To Set Alarm Value

Press the return key until the AL indicator lights. Then set the desired alarm value in units of F or C. If the present temperature exceeds the set alarm value, the alarm output will be issued.
In Case of Sensor Failure
The error message FFF or ------ will appear on the main display if the temperature sensor short-circuits or breaks.

Installation

J Mounting

All E5CS-X models conform to DIN 43700 standard. Recommended panel thickness is 1 to 4 mm (0.04 to 0.16 in). Insert the temperature controller, back end first, into the panel cutout. Mount the adapter (Y92F-30) supplied with each unit 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.

J Connections

Connection Examples
Use M3.5 solderless terminals with the temperature controllers M3.5 self-rising pressure plate screws. For solder-dipped leads, strip the lead wire 6 to 12 mm (0.24 to 0.47 in) and carefully insert the wire tip. Do not tighten the terminal screw with excessive force.

Removal

Loosen the screws on the adapter and push the hook open to remove the adapter.
7.5 (0.29) 7.3 (0.29) max.

19 (0.75) Screw

6 to 12 (0.24 to 0.47)

J Environment

Do not install the temperature controller in a location where there is a lot of dust or corrosive gases. Also avoid a location where the temperature controller is subjected to heavy vibration, shock, splashes of water or oil, and high temperatures. Separate the temperature controller from equipment that generates strong, high-frequency electrical noise such as welding equipment.

J Recalibration

The E5CS-X temperature controller can be recalibrated by a factory-authorized repair service. Contact Omron for the location near you. Unauthorized recalibration of the controller will void the warranty and may lead to erratic operation.

Sensor Input Connections

The lead wires connecting the platinum RTD to the temperature controller must be separated from the power lines an the load lines, wherever possible, to prevent them from being inducted by electrical noise. Use the specified compensating conductors for the thermocouple input type temperature controllers. Use lead wires having a small resistance for the platinum RTD type temperature controllers.

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%.
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.

Setting the Alarm Mode

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, 2 Mode No alarm function Upper- and lower-limit alarms Upper-limit alarm OFF Alarm output
Lower-limit alarm Upper- and lower-limit range alarm Upper- and lower-limit alarms with standby sequence (see note) Upper-limit alarm with standby sequence (see note) Lower-limit alarm with standby sequence (see note) Absolute-value alarm

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.
Set pin 3 to ON when the Temperature Controller is used to control a cooling device, such as a freezer.
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. Follow the steps described below. 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.

P X 5 6

Pin 1 ON: Temperature Controller performs PID control.
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
Conversely, if the Temperature Controller is used to control a cooling device such as a freezer, set pin 3 to ON.
Control output OFF 20 seconds
ON Normal output OFF Set temperature
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.

Control output ON OFF

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 3.75C 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
Temperature displayed 100C 109C 84C
(without shift) (offset by +9C) (offset by 16C)
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.

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 Controllers 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

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.
