Operation Indicators

1.AL1 (alarm 1)

Lights when alarm 1 output is ON.

AL2 (alarm 2)

Lights when alarm 2 output is ON.

2.HB (heater burnout alarm display)

Lights when a heater burnout is detected.

The heater burnout alarm remains ON by setting the heater burnout latch. To reset, turn the power supply OFF and then ON or set the heater burnout alarm value to “0.0A.”

3.OT1, OT2 (control output 1, control output 2)

Lights when control output 1 and/or control output 2 (cool) are ON.

4.STP (stop)

Lights when control of the E5CN has been stopped. During control, this indicator lights when an event or the run/stop function has stopped, or this indicator is out.

5.CMW (communications writing control)

Lights when communications writing is enabled and is out when it is disabled.

Temperature Unit

The temperature unit is displayed when the display unit parameter is set to a temperature. Indication is determined by the currently selected “temperature unit” parameter set value. When this parameter is set to “°C,” “ ” is displayed, and when set to “°F,”

“ ” is displayed.

Level Key

Press this key to select the setup level. The setup level is selected in this order: “operation level” ←→ “adjustment level,” “initial setting level” ←→ “communications setting level.”

No. 1 Display

Displays the process value or parameter type.

No. 2 Display

Displays the set point, manipulated variable, or set value (setup) of the parameter.

Up Key

Each press of this key increases values displayed on the No.2 display. Holding down this key continuously increases values.

Down Key

Each press of this key decreases values displayed on the No.2 display. Holding down this key continuously decreases values.

Level + Mode Keys

This key combination sets the

E5CN to the “protect level.”

Mode Key

Press this key to select parameters within each level.

Operation

INITIAL SETUP

On previous Controllers, sensor input type, alarm type and control period were set on DIP switches. These hardware settings are now set in parameters in setup menus. The and keys are used to switch between setup menus, and the amount of time that you hold the keys down determines which setup menu you move to. This section describes two typical examples.

Note: On the E5GN, the Key is the Key.

1. ON/OFF Control

Typical Application Examples

Typical Example

Input type:	0 K thermocouple -200 to 1300°C
Control method:	ON/OFF control
Alarm type:	2 upper limit
Alarm value 1:	20°C (For setting deviation)
Set point:	100°C

Change only the alarm value 1 and set point. The rest must be left as default settings.
