Safety Information

We use caution symbols where needed within this document to draw your at-tention to important operational and safety information.
A “CAUTION” safety alert appears with information that is important for protecting your equipment and performance. Be especially careful to read and follow all cautions that apply to your application.
A “WARNING” safety alert appears with information that is important for protecting you, others and equipment from damage. Pay very close attention to all warnings that apply to your application.
The electrical hazard symbol, (a lightning bolt in a triangle) precedes an electric shock hazard CAUTION or WARNING safety statement. Further explanations follow:

Document Overview
The purpose of this Quick Start Guide (QSG) is to acquaint the user with the F4T/D4T High Density (HD) Flex Modules and associated wiring.

Product Overview
Flex modules serve as the interface between real-world devices and the F4T/D4T system. The flex modules described in this document offer various input and output options and greater density (more than 1) than the standard flex modules. With the exception of the Dual SSR module, all of these modules can be placed in any available slot.

Available F4T/D4T Literature and Resources
All of the user documents listed below can be found on the Watlow website: http://www.watlow.com. The Watlow Support Tools DVD can be acquired by contacting Watlow customer service (507-494-5300).

Installation and Wiring
To install the flex module:

Note the part number to determine the number and type of inputs or outputs available to be connected in step 7.
Turn off the device power.
Select a compatible base slot for the module. See the Flex Module-Slot Dependencies table below. If replacing a module, remove the old module.
Affix corresponding slot number labels (provided) to the module and the removable screw terminal block.
With the component side of the module facing right (viewing the F4T/D4T from the rear) insert the module into the slot until it latches.
Remove the screw terminal block from the module.
Wire field devices to the appropriate terminals. Wiring details for each in-put 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 F4T/D4T.

Note
If the flex module is a replacement with the same part number and slot position, the F4T/D4T 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 before 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 to the right.

Wiring
Before 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 F4T/D4T, 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 a 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 the 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
