The following introduces the main functions of the E5CN. For details on each
function and how to use the functions, see Section 3 onwards.
• The following input sensors can be connected for temperature input:
Thermocouple
Infrared temperature sensor type : ES1A
Platinum resistance thermometer
Analog input
• Control output is either relay, voltage output or current output depending
on the model of E5CN.
• If you select heating and cooling control on the E5CN-@2@@, alarm 2
output is used as cooling side output. So, use alarm 1 if an alarm is
needed in heating and cooling control.
• Alarms are supported on the E5CN-@2@@. Set the alarm type and alarm
value, or upper- and lower-limit alarms.
• 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 ON/OFF parameters.
• When the input error output is set to "ON", alarm output 1 turns ON when
an input error occurs.
• Optimum PID constants can be set easily by AT (auto-tuning) and ST
(self-tuning).
• When the option event input unit E53-CNHB is mounted in the E5CN, the
following functions can be achieved by event input:
Set point selection (multi-SP max. 4 points) and run/stop
• The heater burnout alarm (HBA) function is supported when the option
unit (E53-CNHB or E53-CNH03) is mounted in the E5CN.
• Communications according to CompoWay/F* and Sysway are supported
when the option communications unit E53-CNH03 is mounted in the
E5CN.
Communications are carried out over the RS-485 interface.
Note CompoWay/F is a general-purpose serial communications-based unified com-
munications procedure developed by OMRON. CompoWay/F uses com-
mands compliant with the well-established FINS, together with a unified frame
format on OMRON programmable controllers to facilitate communications
between personal computers and components.
