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.

ON when an input error occurs.

, 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.

puts 1, 2, and 3.
