Appendix
Note (1) For the setting ranges for each sensor input, see page 281.
(2) When connecting the ES2-THB, connect it 1:1.
(3) Always connect an AC load to a long-life relay output. The output will not turn OFF if a DC load is
connected, because a triac is used for switching when closing and opening the circuit.
HB, HS, and Heater Overcurrent Alarms (for E5CN/AN/EN Controllers with Heater
Burnout, HS, and Heater Overcurrent Alarms)
Note (1) When the control output 1 ON time is less than 100 ms, heater burnout detection, heater overcurrent
detection, and heater current measurement are not performed.
(2) When the control output 1 OFF time is less than 100 ms, HS alarm, and leakage current measure-
ment are not performed.

Note Contact your OMRON representative for information on using the external power supply for ES1B for
other applications.
