10 Basic-type Digital Temperature Controller E5CN/E5CN-U
USB-Serial Conversion Cable
Note: A driver must be installed in the personal computer. Refer to
installation information in the operation manual for the
Conversion Cable.
Communications Specifications
✽ The baud rate, data bit length, stop bit length, and vertical parity can
be individually set using the Communications Setting Level.

Heater Burnout Alarms, SSR Failure
Alarms, and Heater Overcurrent Alarms
✽1. For heater burnout alarms, the heater current will be measured
when the control output is ON, and the output assigned to the
alarm 1 function will turn ON if the heater current is lower than the
set value (i.e., heater burnout detection current value).
✽2. For SSR failure alarms, the heater current will be measured when
the control output is OFF, and the output assigned to the alarm 1
function will turn ON if the heater current is higher than the set
value (i.e., SSR failure detection current value).
✽3. For heater overcurrent alarms, the heater current will be
measured when the control output is ON, and the output assigned
to the alarm 1 function will turn ON if the heater current is higher
than the set value (i.e., heater overcurrent detection current
value).
