The setting selectors and switch are used to select the temperature sensor type,
the unit number, and the functions to be used with the E5ZE. Refer to 2-3 Setting
Selectors and Switch for details on setting methods.
The input terminal block is connected to a DC power supply, temperature sen-
sor, and ground wire. Refer to 2-5 Power Supply and Input Wiring for details on
wiring procedures.
The communications connector is connected to the communications cable. Re-
fer to the E5ZE Multipoint Temperature Controller Communications Manual
(H77) or the E5ZE-8 Multipoint Temperature Controller DeviceNet Communica-
tions Manual (H104) for details on communications functions and their applica-
tions.

The CT INPUT connector is connected to the Current Transformer (CT) to detect
heater burnout or SSR failure. Use E5ZE-CBL
Connecting Cables to con-
nect to the Connector Terminal Conversion Unit (XW2B-20G5 for M3.5 terminal
screws or XW2B-20G4 for M2.4 terminal screws). Refer to 2-6 Wiring CT Inputs
and Control/Alarm Outputs for details on wiring procedures.
The CONTROL connector is used to connect the control output and memory
bank designation input contacts. Use E5ZE-CBL
Connecting Cables to
connect to the Connector Terminal Conversion Unit (XW2B-20G5 for M3.5 ter-
minal screws or XW2B-20G4 for M2.4 terminal screws). Refer to 2-6 Wiring CT
Inputs and Control/Alarm Outputs for details on wiring procedures.
The ALARM connector for the E5ZE-8A
Standard Models is used for
an alarm output and that for the E5ZE-8V
Heating and Cooling Con-
trol Models is used for cooling control output and alarm output. Use E5ZE-CBL-
Connecting Cables to connect to the following devices.
