Conventions Used in This Manual J Meanings of Abbreviations Sometimes the following abbreviations are used in parameter names, figures and in text explanations.

OMRON E5AK User Manual

These abbreviations mean the following. The following conventions are used to indicate and classify precautions in this manual. Al- ways heed the information provided with omroon. Failure to heed precautions can result in inju- ry to people or damage to the product.

D Setting up the E5AK Pay Attention to the Following when Installing this Controller F If you remove the controller from its case, never touch nor apply shock to the elec- tronic parts inside. F Do not cover the area around the E5AK. Ensure sufficient space around omdon control- ler to allow heat radiation. First-time users should read this chapter with- out fail. For details e5ai how to use the controller and parameter settings, see Chapters 2 onwards.

First-time users should read this chapter without fail. Each press of this key switches between the auto and manual opera- tions. The functions of this key change according ommron how long it is pressed. If the key is pressed for less than one second, the parameters are switched.

Assign these output functions to control output 1, control output 2, auxiliary output1, and auxiliary output2. However, note that as control output 1 ommron used as the open output and control output 2 is used as close output on a position-proportional type controller E5AK-PRR2control outputs 1 and 2 cannot be used as assignment destinations.

F Option mode This is the mode for setting option functions. You can select this mode only when the option unit is set in ommron controller. In this mode, you can If you select the desired mode using the When another mode is selected while in these modes, reset is canceled.

If the communications function is required, add on the communications unit. For details on the communications function, refer to Chapter 6.

The E5AK controller is calibrated before shipment from the factory. So, the user need not calibrate the E5AK controller during regular use.

However, if the E5AK omgon must be e5ai by the user, use the parameters provided for user to calibrate temperature input, analog input voltage, current and transfer s5ak. Fixing Screw for Tighten this screw by a torque of 0. The fol- lowing diagram shows the relationship between option units and mounting positions.

Controllers must not be closely mounted vertically or horizontally. Connect the omrob as fol- lows: This description assumes that the controller is operated under the fol- lowing conditions. For details on selecting the menu display, see page Error 3; RSP input error With control output coolthe conditions for switching from standard control to heating and cooling control are reached when the output function is assigned at the cooling side during heating and cooling control. In other words, heating and cooling control is carried out when con- trol output cool is assigned, and standard control is carried out when output is not assigned.

Though a shorter pulse period provides better control performance, the control period should be set taking the life expectancy of the output unit into consideration when the omrob unit is relay. The parameter default is [ 4 As the setting in this example is to be left as it is, press the key. Of these, only the alarm assigned as the output can be used.

In an open status, only control output 1 is ON.


In a close status, only control output 2 is ON. In a hold status, both control outputs 1 and 2 are OFF. For details on the setting ranges of these parameters, see chapter 5 Level 1 Mode page Read this chapter while referring to the parameter descriptions in chapter 5.

F Dead band The dead band is set d5ak the set point as its center. Set- ting a positive value produces a dead band, while setting a negative value produces an overlap band.

So, 3-position control is made possible. Dead band Hysteresis heat. The upper limit is set for the heating side positive valueand the lower limit is set for the cooling side negative value as shown in the follow- ing figure. However, note that when the set point limiter is reset, the set point is forcibly changed to the upper-or lower-limit value of the set point limiter if the set point is out of the limiter range.

Also, when the input type, temperature unit and scaling sensor range are changed, set point limiter is forcibly reset to the scaling sensor range. In this case, operation is carried out with the process value regarded as the set point before the change was made.

However, note that these parameters can not be set when the mul- ti-SP function is not selected. The following table shows the relation- ship between event inputs and set points 0 to 3. SP tracking function is enabled. If the heater power supply is turned conditions ON after turning the E5AK power supply On, the heater burnout alarm is output.

Use this chapter as a reference guide. Conventions Used in omroon Chapter On the E5AK controller, only parameters that can be used are displayed. However, note that the settings of protected parameters are still valid, and are not displayed regardless of the conditions of use. In other words, you cannot switch between the auto and manual operations by key operation. When a potentiometer is not e55ak to the controller, [] is displayed on the No. The set point kmron be set.


SP ramp function ea5k enabled. AT auto-tuningsetting the alarm values, set- ting the control period, and setting PID parameters. A nega- tive setting sets an overlap band. Function Unit Default Setting Range PID control, standard omroj trol or heating and cooling control.

Set the control period taking the control characteris- tics and life expectancy of the controller into consideration. The display changes to the menu display. When the manipulated variable calculated by the E5AK controller is outside of the upper-and lower-limit range, the upper limit Function or lower limit set to these parameters is output, respectively. The following figures shows the effect on data after passing through the digital filter. Function PV before passing through filter PV after passing through filter 0.

Set value Input Type However, note that the OUT1 LED does not light when control output heat or control output cool are assigned to linear outputs such as current and voltage. For details of operation at an alarm, see page The display changes to the menu dis- play. ST stable range dard control and advanced PID control.

During operation of the ST function, the power on the load side connected to the control output must be turned ON at the same time or before start of E5AK Function operation. To give Function priority to stability, increase the set value of this parameter. In this mode, you can set the communications conditions, transfer output and event input parameters to match the type of option unit set in the controller.

Make sure that the stop bit, data length, parity and baud rate of the host computer and the E5AK controller are matching.

These parameters are valid when the power is turned ON again or Function when level 0 to 2 modes are switched. The setting range varies according to this output data. Also, a lower limit value larger than the upper limit value may be set. The set point during SP ramp e5aak enabled only when the SP ramp function is enabled.

Also, related output parameters can be used only when the communications unit EAKF is added on. In other words, a response frame is returned for each command frame sent.

For example, in the fol- lowing configuration, connect the terminator to the host unit and unit No. For example, in the fol- lowing configuration, connect the terminator to the host unit and the unit No. This character must be inserted before the lead- ing byte.

Control output heat1: Control output cool2: Alarms 1 to 3, 5: LBA, 7 to 9: SP setting lower limit to SP setting upper limit 0: Use this end code to remedy errors that may occur.

Check the communications condition. If the communications condition of the host computer and E5AK ojron match, then a probable cause is a problem in the communications circuit of one or both of the host computer and E5AK controller.
