I/O Configuration and Main Functions Section 1-2
Control Outputs • A control output can be relay, voltage, or current output, depending on the
model.
• With the E5CZ-@2M@@, alarm output 2 is used as control output (cool-
ing) when heating/cooling control is selected. Therefore, use alarm 1 if an
alarm is required while using heating/cooling control.
• With the E5AZ/E5EZ-@3@@@@, alarm output 3 is used as control output
(cooling) when heating/cooling control is selected. Therefore, use alarms
1 and 2 if an alarm is required while using heating/cooling control.
Alarms • Alarms can be used with the E5CZ-@2M@@,or E5CZ-@2T@U. Set the
alarm classification and alarm value or the alarm's 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.
Control Adjustment • Optimum PID constants can be set easily by performing AT (auto-tuning)
or ST (self-tuning).
Event Inputs • The following functions can be executed using event inputs: switching set
points (multi-SP, 4 pts. max.), and switching RUN/STOP status, and
switching between automatic and manual operation.
E5CZ-@2M@@ with E53-CZB or E53-CZHB
E5AZ-@3@M@@ with E53-AZB
E5EZ-@3@M@@ with E53-AZB
Heater Burnout and HS
Alarms
• The heater burnout detection function and the HS alarm function can be
used.

E5AZ-@3HM@@
E5EZ-@3HM@@
Communications
Functions
• Communications functions utilizing CompoWay/F (See note 1.),
SYSWAY (See note 2.), or Modbus (See note 3.) can be used.
RS-485 Interface
E5CZ-@2M@@ with E53-CZH03 or E53-CZ03
E5AZ-@3@M@@ with E53-
AZ03
E5EZ-@3@M@@ with E53-AZ03
RS-232C Interface.(See note 4.)
E5AZ-@3@M@@ with E53-AZ01
E5EZ-@3@M@@ with E53-AZ01
Note (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 Programmable Controllers to facilitate communications be-
tween personal computers and components.
(2) SYSWAY communications do not support alarm 3 output.
(3) Modbus is a communications control method conforming to the RTU
Mode of Modicon Inc.'s Modbus Protocol.
(4) The E5CZ and E5CZ-U do not support the RS-232C interface.
