Technical information

3.3 INPUT WIRING: RTD-PT100 AND THERMOCOUPLE:
Before the controller is ready to be used in a given process, it requires some basic
configuration, such as:
•
Input Type
(T/C, or Pt100) at the tYPE
prompt, section 5.3 (page13).
•
Output Configuration
(control, alarms) at
(ntr
prompt, section 5.3 (page13).
•
Setpoint Variable SV
.
•
PID parameters
(or hysteresis for ON/OFF control), see Cycle-2 (page12).
Other functions, including alarms, ramp to soak, etc., may be useful for a better
system performance.

3.1 GENERAL ELECTRICAL CONNECTIONS:
Notes:
1) For Thermocouple Sensors use appropriate compensated
thermocouple wires.
Model TC33-2010-AC
Model TC33-1100-AC
2) Use copper conductors rated for at least 75 ºC (except on T/C).

NOTE: All terminal screws must be tightened securely. Terminal screws not
properly secured can cause an electrical short that may damage property,
equipment or cause injury or death. Terminal screws improperly secured may fall
into equipment causing possible damage to property or equipment.
