• Take countermeasures such as installing a surge absorber. As an addi-
tional safety measure, provide error detection in the control loop. (Use the
Loop Burnout Alarm (LBA) and HS alarm that are provided for the E5@N-
H.)

Select a surge absorber that satisfies the following conditions.

• On the E5CN-H@2@-500, auxiliary output 1 (SUB1) is output across ter-
minals 7 and 8, and auxiliary output 2 (SUB2) is output across terminals 6
and 8.
• On the E5AN/EN-H@2@-500, auxiliary output 1 (SUB1) is output across
terminals 9 and 10, auxiliary output 2 (SUB2) is output across terminals 7
and 8.
• On the E5AN/EN-H@3@-500, auxiliary output 1 (SUB1) is output across
terminals 9 and 10, auxiliary output 2 (SUB2) is output across terminals 7
and 8, and auxiliary output 3 (SUB3) is output across terminals 14, 15
and 16.
• When the Input Error Output parameter is set to ON, the output assigned
to the alarm 1 function turns ON when an input error occurs.
• If the Remote SP Input Error Output parameter is set to ON, the output
assigned to the alarm 1 function will turn ON when an RSP input error
occurs.
• When the HB alarm, HS alarm, or heater overcurrent alarm is used with
the E5CN-H (with E53-CN@H/HH@N2), alarms are output to the output
assigned to the alarm 1 function.
• When the HB alarm, HS alarm, or heater overcurrent alarm is used with
the E5AN-H/EN-H, alarms are output across terminals 9 and 10.
• On the E5CN-H, when heating/cooling control is used, auxiliary output 2
becomes control output (cooling).
• On the E5AN-H and E5EN-H, when heating/cooling control is used, con-
trol output 2 becomes the control output (cooling).
• For models that have a heater burnout alarm, an OR of the alarm 1 func-
tion and the HB alarm, HS alarm, or heater overcurrent alarm is output. If
the alarm 1 function is to be used for HB alarm only, set the alarm 1 type
to 0 (i.e., do not use alarm 1 function).
• The following diagrams show the internal equalizing circuits for auxiliary
outputs 1, 2, and 3.
