Auxiliary Control Module (ACM) – Optional
The ACM is an optional module used to expand the functionality of the TEC2 actuator.
There are several versions of the ACM available: Futronic, Controlinc, and Auxiliary Relay
Module (ARM). The Futronic ACM may be used alone or with the ARM stacked on top.
The Controlinc ACM is used with a Communication Adapter Module (CAM). The ARM may
also be installed alone. Each ACM can be supplied with the TEC2 actuator or provided later
as an upgrade.
The ACM has two 4-20mA analog input and two 4-20mA analog outputs. Only one of
the analog input could control at any time. Both of these inputs are configurable. Analog
Output #1 is position feedback and Analog Output # 2 is torque. By default, the two analog
outputs are used for valve position and torque feedback.
The Controlinc ACM has two analog inputs and two analog outputs. The analog inputs and
output may be used for generic data acquisition and control by the network host or for the
closed loop control. The ACM is normally configured to allow the host to control the analog
output; the host can write a 12-bit value between 0-4095 via the network to generate a
4-20mA output.
3.6.1 Wiring the ACM
ACM modules may be installed only by factory-trained technicians. Only one
Futronic or Controlinc ACM can be installed at a time inside the round cover
nearest the display end. The Futronic or Controlinc ACM connects to the Central
Control Module (CCM) for logic control functions and to the Separate Terminal
Chamber (STC) for user wiring connections.
To wire the ACM, connect the wires in accordance with
Figure 3-9
and
Figure
3-10
as applicable. See
Section 3.3, Electrical Connections
for general electrical
connection requirements.

The ARM can be installed with the Futronic ACM by stacking it on top of the
Futronic ACM and connecting to the STC. See
