Chapter 2: Install and Wire

Getting Started Quickly...The Logical Approach

The steps below outline installation and wiring for the base alone. More detail for each is
provided in the following sections.

1. Using this document for orientation, nd the base part number and note any installed
options as well as input voltage requirements.

2. Mount/install the base in the panel (see instructions below for panel mount or ush

mount options).

3. Ensure that incoming power is off and connect to the base power supply connector (see
section "Wiring the F4T Base").

4. Make note of any I/O module slot dependencies installing each one into an appropriate
base slot (see graphic entitled F4T Slot Dependencies under "Flex Module Installation").

5. Connect the wires from each eld device to the associated I/O module connector (see
section "Wiring the Modules").

6. Insert all wired I/O connectors onto the applicable modules and apply power to the
base.

7. Connect the controller to a computer running Composer™ software using an Ethernet

Installing the F4T

Panel Mounting the Base

1. Make the panel cutout using the mounting template dimensions above and insert the
case assembly into the panel cutout.

2. While pressing the case assembly rmly against the panel, slide the Retention Collar
over the back of the controller until the gasket is compressed.

3. For an IP65 seal, alternately place and push
the blade of a screwdriver against each of the
the four corners of the retention collar assem­bly. Apply pressure to the face of the control­ler while pushing with the screwdriver. Don't
be afraid to apply enough pressure to properly
install the controller. The seal system is com­pressed more by mating the retention collar
tighter to the front panel. If you can move the
case assembly back and forth in the cutout, you
do not have a proper seal. The tabs on each side
of the retention collar have teeth that latch into
the ridges on the sides of the controller. Each
tooth is staggered at a different depth from the
front so that only one of the tabs, on each side,
is locked onto the ridges at a time.

Flex Module (FM) Characteristics

Many of the modules appear to look alike at rst glance, therefore, it is always recommend-
ed that the module part number be noted and veried

prior to plugging it into any of the available slots in a
base. Each module is identied with a part number locat­ed on the back side of the assembly right below the con­nector (black label), as seen in the graphic to the right.

Flex Module Installation - To view video go to www.watlow.com/F4T

Some Flex Modules require that they be installed in specic slots within the base. As an

example, if a communications card is to be installed, it must be placed in slot 6. Slot 6 can
receive and accept any card, however, it is the only slot that allows for a communication
card (see table to the right).

Slots are keyed such that modules cannot be inserted upside down. Insert modules with the
component side facing the right when viewing the controller from the rear.

Installing the modules:

1. Note the part number to determine the
types of inputs and outputs available to be
connected in step 7.

2. Turn off power to the controller.

3. Select a slot for the module (see table to
right). If replacing a module, remove the
old module.

4. Afx corresponding slot number labels
(provided) to the module and to the re­movable screw terminal block.

5. 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.

6. Remove the screw terminal block from the module.

7. Wire eld devices to the appropriate terminals (see. Wiring details for each input and
output are provided in the following sections.

8. Reconnect the wired screw terminal block to the module. Be sure to reconnect the ter­minal block to the correct module.

9. Restore power to the controller.

Note:

If a module is swapped out and replaced with a different type or moved to another open
slot after configuration, the controller will no longer function properly without being re­configured using Composer™ software.

Note:

To minimize the possibility of unwanted downtime due to a module being removed and
installed into the wrong slot, affix the slot number labels (as directed in step 4 above) to
each module (as shown in the graphic below, white circle) and each removable screw ter­minal block.

Wiring the Modules

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.

AVERTISSEMENT: Pour prévenir tout endommagement du régulateur, ne pas faire de raccor-

dements à des bornes inutilisées.

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.

AVERTISSEMENT: les charges inductives de commutation de lampes témoins (bobines de re-

lais, solénoïdes, etc.) avec des options de sortie à relais mécanique, de relais statique ou col­lecteur ouvert requièrent un dispositif antiparasite R.C.

Note:

It is possible that the terminal strip labeling for any given module could be the same. For
example, if a Thermocouple input module is installed in slot 1 and 2, each slot would have
S1 and R1 on its label. When referencing either of these inputs the differentiating factor is
the module slot number, therefore the reference should be input 1 of slot number x.

Note:

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

Note:

The F4T meets IP10 requirements when the empty slots have slot caps installed.

Note:

Default Ethernet Parameters and Settings

The bracketed bold settings below represent the defaults as delivered from the factory:

• IP Address Mode: [DHCP], Fixed

- DHCP, Dynamic Host Conguration Protocol, allows for dynamic distribution of network

settings by a DHCP server.

- Fixed, also referred to as a static IP address, is congured manually for a specied net­work.

• Actual IP Address: [192.168.0.222]

• Actual IP Subnet: [255.255.255.0]

- Subnet, a method used to logically divide and isolate networks.

• Actual IP Gateway: [0.0.0.0]

- Gateway, is a device used on the network to route messages with IP addresses that do not
exist on the local network.

• MAC Address: xx:xx:xx:xx:xx:xx (Will be different and unique for each controller)

- MAC address, is a manufacturer supplied address for the network interface card.

• Display Units: [°F] (Fahrenheit), °C (Celsius)

• Modbus® TCP Enable: [Yes], No

- Modbus is an industrially hardened eld bus protocol used for communications from the

controller to other devices on the network.

• Modbus Word Order: [High], Low

- Modbus allows a user to select the word order of two 16-bit words in oating point val­ues.

• Data Map: [1], 2

- Data Map, the user can switch Modbus registers from the comprehensive listing of F4T

To change Ethernet parameters:

1. Push the Menu, Settings and Network buttons, in that order.

2. Under "Communications Channels" push Ethernet.

3. Change desired settings.

4. Cycle power to the F4T (changes to IP address will take effect until this step is performed)

Watlow F4T System • 26 • Chapter 3 Connecting to a PC

Connecting the F4T Base to a PC

DHCP Connection

There are two ways to connect the F4T over Ethernet to a PC (Fixed IP or DHCP). Because
the F4T is delivered as a DHCP client, we'll take a look at this method rst. The picture
below shows two F4T controllers connected through a switch to a DHCP server. When the
F4Ts are powered up on the network the
DHCP server will assign IP addresses to
them. Using this method allows the F4Ts
to come up in the same network as the PC
with minimal changes to the default F4T

Ethernet conguration.

To connect using DHCP:

1. Connect Ethernet cables from F4T RJ45
connector to the Ethernet switch.

2. Cycle power on the F4T controllers.

3. DHCP server will detect them on the
network and give them IP addresses
automatically.

Fixed IP Connection

If it is desired to connect the F4T directly to a PC as shown in the graphic below follow the

steps below to do so. It should be noted too that there are alternatives to the steps dened

below, this is one way to do this.

To connect using Fixed IP changing PC IP address:

1. Connect Ethernet cables from F4T RJ45 connector
to PC Ethernet port.

2. On the PC navigate to the control panel and click
on Network and Sharing Center

3. Click on Change adapter settings

4. Double-click on the Local Area Connection (the
Ethernet port where cable is connected icon).

5. Click the Properties button.

6. Double-click on Internet Protocol Version 4 (TCP/IPv4) button.

7. Click the radio button identied as Use the following IP address.

8. Change the IP address so that the rst 3 octets match the rst 3 octets of the F4T IP

address while ensuring that the last octet for both the PC and the F4T are unique and
between 0 and 255. If there are other devices on this network all must have a unique ad­dress.

9. Change the Subnet mask to match what was entered for the F4T.

10. Click OK when done (this change to the IP address will take effect immediately)

To connect using Fixed IP changing F4T IP address:

1. Push the Menu, Settings and Network buttons, in that order.

2. Under "Communications Channels" push Ethernet.

3. Change desired settings to match the PC ensuring a unique IP address for each.

4. Cycle power to the F4T (changes to IP address will not take effect until this step is pe-

formed).

Chapter 4: Calibration

Calibrating the F4T Inputs

All controllers are calibrated and are accurate to the specied specications (see Appendix
for specications) when they ship from the manufacturing facility.

If an input is suspect as being out of calibration it is recommended that prior to perform­ing any calibration procedure that the user verify that the displayed readings are not within

published specications. Input a known value from a precision source to the analog input and

subtract the displayed value with the known value and compare this difference to the pub­lished accuracy range specication (see Appendix for specications) for that type of input.

Use of the Calibration Offset parameter found when viewing the Universal Input parameters
from within Composer™ software or while viewing the input from the front panel Operations
menu, shifts the readings across the entire displayed range by the offset value. Use this pa­rameter to compensate for sensor error or sensor placement error. Typically this value is set
to zero.

Required Equipment When Performing Calibration

Obtain a precision source for millivolts, volts, milliamperes or resistance depending on the
sensor type to be calibrated. Use copper wire only to connect the precision source to the
controller’s input. Keep leads between the precision source and controller as short as possi­ble to minimize error. In addition, a precision volt/ohm meter capable of reading values to 4
decimal places or better is recommended. Prior to calibration, connect this volt/ohm meter
to the precision source to verify accuracy.

Actual input values do NOT have to be exactly the recommended values, but it is critical
that the actual value of the signal connected to the controller be accurately known to at
least four digits.

Watlow F4T Install & Troubleshooting • 30 • Chapter 4 Calibration

Calibration of Analog Inputs

To calibrate an analog input, you will need to provide a source of two electrical signals or
resistance values near the extremes of the range that the application is likely to utilize. See
recommended values below:

Sensor Type Precision Source Low Precision Source High

Thermocouple 0.000 mV 50.000 mV
Millivolts 0.000 mV 50.000 mV
Volts 0.000V 10.000V
Milliamps 0.000 mA 20.000 mA

100 Ω RTD 50.00 Ω 350.0 Ω
1,000 Ω RTD 500.0 Ω 3,500 Ω
Thermistor 5 kΩ 50.00 5,000
Thermistor 10 kΩ 150.0 10,000
Thermistor 20 kΩ 1,800 20,000
Thermistor 40 kΩ 1,700 40,000

Potentiometer 0.000 1,200

CAUTION:

Control loops, alarms, limits and any other functions that receive signals from the analog
input will act on the high and low signals applied in this procedure.

Note:

When calibrating a Universal Input configured as a 3-wire RTD, ensure that the calibrated
source is connected across R and both T and S inputs.

Note:

If the user exits this procedure at any point by clicking cancel or simply navigating away
to another screen, the previous calibration for the selected input will be restored.

Note:

The calibration values entered using this procedure will be overwritten whenever the con­troller has the factory settings restored.

Note:

There are three security settings that can be applied to the calibration screens through
the Diagnostics and Troubleshooting (see the System Overview section of the F4T Setup
and Operation User's Guide for more information) access point:

1. Full Access - full capabilities to calibrate available

2. Read Only - first calibration screen displayed

Replacing the Battery

All F4T controllers are equipped with a eld replaceable battery. In a worse case scenario,

the battery should be replaced every 7.5 years. If a replacement is required, the part num­ber for the battery is BR 2032. The Watlow part number for the battery is: 0830-0858-0000

Identifying the battery location:

1. Orient the controller as shown in the picture below.

2. Notice that the battery compartment is located just below the two USB.

Removing the old battery:

1. Ensure all power is off to the F4T.

2. Insert a small screwdriver into the hole provided on the side of the controller as shown
below.

3. Place screwdriver into the bottom of the white battery holder and apply downward
pressure to slide the battery out of the housing. Once removed, make note of the
polarity as seated in the holder.

Watlow F4T Install & Troubleshooting • 39 • Chapter 5 Troubleshooting

Installing a new battery:

1. Observing polarity (as shown in the previous graphic), insert the new battery from the
bottom of the holder (2 open slots - red circles as shown in picture below).

2. Insert the battery perpendicular to the plastic housing.

3. Turn and secure the battery so that it sits under the tabs located on the top of the
holder.

4. Insert the holder into the controller housing with the positive side of the battery ori­ented to the left as shown below.

Note:

If the battery is fully discharged it may be dis-
posed of in normal municipal waste. Because there
will always be some residual metals remaining in
the battery Watlow recommends that this battery
be recycled.
