Temperature Controller METICOM CTI Series
CAUTION
When turning on the system, you should turn on all circuit breakers before powering on the HMI. You
may experience communication issues if you do not follow this sequence.
After turning on the system ensure the fans are running.
Never allow the fan inlets or outlets on the unit become blocked. If these become blocked insufficient
airflow can cause damage to the system.
When switching off the system, you must wait 30 seconds before switching on. You may experience
communication issues if you do not follow this sequence.
Chapter 1 Introduction
1.1 CTI Series Mainframe Configuration
The CTI controller series is made up of 3 different models of mainframes depending on the number of
zones required. These are referred to as CTI-100, CTI-200, and CTI-300.
All the mainframes utilize the same temperature control module CTI-M2, and the same sequential
valve gate control module CTI-V2.
Access to all user serviceable parts, such as fuses, are done through the front of the controller by
loosening the upper and lower screws on each heat sink and removing the modules.
The connectors for the mold-power and thermocouple cables, and the connectors for valve gate
control cables, are located at the rear of the mainframe.

1.2 Control Modules
The mainframes are available with 2 styles of control modules depending on requirements. The
modules are fully interchangeable across all mainframe designs. The externally mounted heat sink
and integrated design reduce maintenance cost and downtime.
