• The unit may be damaged if the voltage output from the SSR drive output terminals is short-circuited.

• When setting the “Input type” parameter, refer to the “Input type” table in the PDF to ensure settings are correct, as incorrect settings will cause measurement errors.

• Use a single OMRON E5CC unit per power supply circuit for CT connection. If multiple units are used, errors will occur in the measured current values.

Dimensions:

• The overall dimensions of the OMRON E5CC are 48 x 48 mm (front) and 60 mm (depth).

Panel Cutout:

• The panel cutout size should be 45 x 45 mm.

• The recommended panel thickness is 1 to 5 mm.

Installation Mounting Methods:

• Individual Mounting:

1. Insert the OMRON E5CC into the mounting hole in the panel.

2. Push the adapter in from the terminals on the rear until the adapter contacts the panel and is temporarily secured.

3. Tighten the two mounting screws on the adapter. Alternate between the top and bottom screws, tightening them a little at a time to keep them at the same tightness.

• Side-by-side Mounting:

1. Insert the OMRON E5CC controllers into the mounting holes in the panel.

2. Insert adapters on the Digital Controllers.

3. Insert a watertight packing if waterproofing is required. The OMRON E5CC is not waterproof if mounted side-by-side without watertight packing.

To maintain a waterproof construction, insert the watertight packing onto the OMRON E5CC. When multiple units are mounted, the waterproof construction is lost.

The wiring for the OMRON E5CC depends on the specific model. Use M3.5 crimp terminals with a width of 7.2 mm or less. The terminal arrangement is shown below for different models. Always ensure power is OFF before wiring.

• No. 2 Display (SV): Shows the set point (SV), a manipulated variable, or a parameter setting. It is displayed in green.

Indicators:

• (1) Control output 1 indicator (OUT1): Lit while the control output 1 is ON.

• (2) Auxiliary output 1 indicator (AUX1): Lit while auxiliary output 1 is ON.

• (3) Auxiliary output 2 indicator (AUX2): Lit while auxiliary output 2 is ON.

• (4) STOP indicator (STOP): Lit while control is stopped.

• (5) CMW indicator: Not used on this model.

Keys:

• (6) Level key: Press for less than 1 second to switch between levels. Press for 1 second or more to move from the Operation Level to the Adjustment Level. Press for 3 seconds or more to move from the Operation Level to the Initial Setting Level.

• (7) Mode key: Changes the parameter within a level.

• (8) Down key: Decreases the setting.

• (9) Up key: Increases the setting.

The OMRON E5CC has several operational levels. Here is how to navigate between them:

• Power ON: When the power is turned on, the OMRON E5CC starts in the Operation Level. This is the default level for monitoring the process value (PV) and set point (SV).

• Operation Level:

– Use the Up and Down keys to change the set point (SV).

– Press the Mode key to cycle through other parameters in this level, such as the alarm value.

• To move to the Adjustment Level:

– From the Operation Level, press and hold the Level key for at least 1 second.

• To move to the Initial Setting Level:

– From the Operation Level, press and hold the Level key for at least 3 seconds.

– Note: You cannot move to the Initial Setting Level if control is running (STOP indicator is OFF). First, stop the operation by changing the “Run/Stop” parameter to “STOP”.

• To move to the Protect Level:

– From the Initial Setting Level, press the Mode key to navigate to the “Protect Level” parameter. Then use the Level key to enter it.

– Alternatively, in any level, press and hold the Level and Mode keys at the same time for 1 second to move directly to the Protect Level.

• To return to the Operation Level:

– From any other level, press and hold the Level key for at least 1 second to return to the Operation Level.

The OMRON E5CC supports various sensor inputs. The input type must be set in the Initial Setting Level. The available types and ranges are listed below:

Note: The default sensor type is Thermocouple K. The display unit (°C/°F) is also set in the Initial Setting Level.

You can initialize the parameters of the OMRON E5CC to their default factory settings. This action is performed from the Protect Level.

1. Press and hold the Level and Mode keys at the same time for at least 1 second to move to the Protect Level.

2. Press the Mode key until the “Initialize” parameter is displayed.

3. Use the Up or Down key to change the setting to “ON”.

4. To execute the initialization, either press the Level and Mode keys at the same time for 1 second, or turn the power OFF and then ON again.

This will reset all parameters in the Initial Setting, Adjustment, and Protect Levels to their default values.

The OMRON E5CC provides various alarm types that can be assigned to the auxiliary outputs. The alarm type is selected in the Initial Setting Level.

Note: Alarm values are set in the Operation Level or Adjustment Level. The default alarm type is “Upper limit” (No. 2).

When an error occurs on the OMRON E5CC, the display will show an error code. The following table explains the error codes and the necessary actions to resolve them.

If the display shows all OFF, it indicates a power supply error or that the OMRON E5CC has failed. Check the power supply voltage, wiring, and terminal connections.
