1.For heating/cooling control applications, the auxiliary outputs on the 2-point models are used for cooling control.
On the 4-point models, heating/cooling control can be performed for two input points only.
2.When using the heater burnout alarm, purchase a Current Transformer (E54-CT1 or E54-CT3) separately.
3.This unit mounts to the left of the CelciuX° (EJ1) configuration and enables PROFINET or Modbus/TCP network connection. Combine the HFU-ETN with an EDU_-NFLK end unit to use with other devices supporting Modbus-RTU like E5_N temperature controllers and MX2 Inverters.
4.An End unit is always required for connection to a Basic unit or an HFU. An HFU cannot operate without a Basic unit.
5.Heating/cooling control is not supported for gradient temperature control.
6.When using the heater burnout alarm, use a Current Transformer (E54-CT1 or E54-CT3) (sold separately).
7.An End-unit (EDU) is always required to connect an HFU and or a Basic TC unit for Communications and Power supply.
A GTC (Gradient Temperature Control) basic TC unit always requires a GTC HFU unit.
8.Inputs are fully multi-input. Therefore, platinum resistance thermometer, thermocouple, infrared thermosensor, and analog input can be selected.
