Wiring Terminals Section 2-2
E5AZ/EZ
• A voltage output (control output) is not electrically isolated from the inter-
nal circuits. When using a grounding thermocouple, do not connect any of
the control output terminals to the ground. If control output terminals are
connected to the ground, errors will occur in the measured temperature
values as a result of leakage current.
• Control output 1 (Voltage output) is not isolated.
Alarm Outputs 1, 2, and 3 • On the E5CZ-@2M@@, alarm output 1 (ALM1) is output across terminals
7 and 8, and alarm output 2 (ALM2) is output across terminals 6 and 8.
• On the E5CZ-@2T@U, alarm output 1 (ALM1) is output across terminals 7
and 8, and alarm output 2 (ALM2) is output across terminals 7 and 9.
• On the E5AZ/EZ-@3@@@@, alarm output 1 (ALM1) is output across ter-
minals 9 and 10, alarm output 2 (ALM2) is output across terminals 7 and
8, and alarm output 3 (ALM3) is output across terminals 5 and 6.
• When the “input error output” parameter is set to ON, alarm output 1 turns
ON when an input error occurs.
• When the HB alarm or the HS alarm is used with the E5CZ-@2M@@ with
E53-CZH03 or E53-CZHB alarms are output across terminals 7 and 8.
• When the HB alarm or the HS alarm is used with the E5AZ-@3H@@@or
the E5EZ-@3H@@@, alarms are output across terminals 9 and 10.
• On the E5CZ and E5CZ-U, when heating/cooling control is used, alarm
output 2 becomes control output (cooling).
• On the E5AZ and E5EZ, when heating/cooling control is used, alarm out-
put 3 becomes control output (cooling).
• For models that have a heater burnout alarm, an OR of alarm output 1
and the HB alarm/HS alarm is output. If ALM1 is to be used for HB alarm
only, set the alarm 1 type to 0 and do not use alarm output 1.
• The following diagrams show the internal equalizing circuits for alarm out-
puts 1, 2, and 3.
