Note
This section introduces the main E5AZ/E5EZ functions. For details on particu-
lar functions and how to use them, refer to SECTION 3 Basic Operation and
following sections.
• The following input sensors can be connected for temperature input:
Platinum resistance thermometer
Thermocouple
Infrared temperature sensor: ES1B
Analog input
• A control output can be relay, voltage, or current output, depending on the
model of E5AZ/E5EZ.
• With the E5@Z-@3@@, alarm output 3 is used as control output 2 (cool-
ing) when heating/cooling control is selected. Therefore, use alarm 1 and
2 if an alarm is required while using heating/cooling control.
• Alarms can be used with the E5@Z-@3@@. Set the alarm type and alarm
value or the alarm value upper and lower limits.
• If necessary, a more comprehensive alarm function can be achieved by
setting the standby sequence, alarm hysteresis, close in alarm/open in
alarm, and alarm latch parameters.
• When the "input error output" parameter is set to ON, alarm output 1 turns
ON when an input error occurs.
• Optimum PID constants can be set easily by performing AT (auto-tuning)
or ST (self-tuning).
• With the E53-AZB, the following functions can be executed using event
inputs: switching set points (multi-SP, 4 pts. max.), and switching RUN/
STOP status.
• With the E53-AZH, the heater burnout detection alarm function can be
used.
• With the E53-AZ01 or E53-AZ03, the communications functions utilizing
CompoWay/F (See note 1.) or SYSWAY can be used.
E5@Z-@3@03: RS-485 interface
E5@Z-@3@01: RS-232C interface
1. CompoWay/F is an integrated general-purpose serial communications
protocol developed by OMRON. It uses commands compliant with the well-
established FINS, together with a consistent frame format on OMRON Pro-
grammable Controllers to facilitate communications between personal
computers and components.
2. SYSWAY communications cannot be used for the alarm 3 output.
