Document Overview

The purpose of this Quick Start Guide (QSG) is to acquaint the user with the F4T Flex Modules and associated wiring.

Product Overview

Flex modules add functionality, inputs and outputs to an F4T system. The flex modules described in this document offer various input and output options as well as a safety over/under temperature limit. Each module can include one analog input and up to two outputs. All of these modules can be placed in any available slot.

Installation and Wiring

To install the flex module:

Note the part number to determine the types of inputs and outputs available to be connected in step 7.
Turn off power to the controller.
Select a slot for the module. If replacing a module, remove the old module.
Affix corresponding slot number labels (provided) to the module and to the removable screw terminal block.
With the component side of the module facing right (viewing the controller from the rear) insert the module in to the slot until it latches.
Remove the screw terminal block from the module.
Wire field devices to the appropriate terminals. Wiring details for each input and output are provided in the following sections.
Reconnect the wired screw terminal block to the module. Be sure to reconnect the terminal block to the correct module.
Restore power to the controller.

Note:
If the flex module is a replacement with the same part number and slot position, the controller uses it immediately when powered up. Otherwise, use Composer software to configure the F4T/D4T to expect and use the module.

Module Characteristics

Description and Identification

Many of the modules appear to look alike at first glance, therefore, it is always recommended that the module part number be verified prior to plugging it into any of the available slots in a base. Each module is identified with a part number located on the back side of the assembly next to the screw terminal block, as displayed in the graphic above.

FM[ M, L ]A – A – A

Wiring
Prior to wiring any of the I/O modules described in this document it is recommended that the warnings and notes listed below be reviewed.

CAUTION:
To prevent damage to the controller, do not connect wires to unused terminals.

Note:
Maintain electrical isolation between the analog input, digital input-outputs, switched dc/open collector outputs and process outputs to prevent ground loops.

Note:
Modules IP10 when properly installed in base enclosure with slot caps in empty slots.

CAUTION:
Switching pilot duty inductive loads (relay coils, solenoids, etc.) with the mechanical relay, solid-state relay or open collector output options requires use of an R.C. suppressor for AC load or a diode for a DC load.

Note:
Wire size and torque for screw terminations:

0.0507 to 3.30 mm² (30 to 12 AWG) single-wire termination or two 1.31 mm² (16 AWG)
0.57 Nm (5.0 lb.-in.) torque

Note:
Use of 2-wire RTDs adds error to the measurement based on wire lead length (see table). 3-wire auto compensates for wire resistance.
