SC-F70SC-F70 PID Operation Operating Instructions
Preface
Thank you for choosing the SC-F70SC-F70 Multicontroller, a
multipurpose, multifunction, easy-to-use controller for your steam system.
About This Book
The multicontroller (hereafter, called the controller) can be used to
control various things, as listed here:
∑Auto-tuning PID operation and heating, cooling PID operation (These
operating instructions)
∑Pressure control
∑Temperature control
We have prepared a book containing operating instructions for each type
of use.
It is important that you use the correct book for your controller.
When the controller was shipped from our factory, the correct book should
have been packed according to your order, but please recheck it now. This
book contains instructions for using the controller for Auto-tuning PID
operation and heating, cooling PID operation.
This book provides, for both inexperienced users and experts, information
for installing and operating your controller, and troubleshooting problems.
It also contains product specifications and warranties.
For Your Safety
∑∑
∑∑
∑Safety mark
Every safety notice in this book is shown with a safety mark ( ).
Please read these notices carefully before proceeding.
Danger: Protecting electrical terminals
This product is designed and manufactured to be used mounted on an
instrument panel and the electrical terminals on the back side of the
controller are left exposed.
Therefore, the user must install a protective cover over the terminals to
prevent electrical shock to the user or damage to the multicontroller.
This book will be updated from time to time according to improvements made to
the product. But if you find a discrepancy between the descriptions in this book
and actual operation, and need help, contact TLV.

SC-F70SC-F70 PID Operation Operating Instructions
1.2 Setting Feature Jumpers
The following feature jumpers can be set to customize your controller.
∑To select measurement input type
∑To select analog input (used only with the analog input feature).
These jumpers are set at the factory to your order specifications.
If BOTH of the following conditions are met, there is NO need to check
the jumper setting. You can go to "1.3 Attaching to the Panel" directly.
1. The sensor to be used is a pressure transmitter MBS33M (from
Danfoss A/S), KH15 (from Nagano Instrument Corp.), or a
temperature sensor TR1 obtained from TLV.
2. Remote analog setting operation is not used.
Warning:
Do not try to use the controller without setting the jumpers correctly
according to your mode of operation. If you do, an unexpected
malfunction may arise.
Use these steps to set the jumpers
1. Make sure the controller is turned off.
2. Remove the controller body from its
case (see Figure 1).
1. While pushing the stopper tab 1
upward,
2. Pull the body by the frame of the
display panel 2 .
3. To identify the two groups of jumpers,
see Figure 2.
Warning:
To prevent damage, do NOT touch any metal parts on the boards
when you do the next step.
4. Using tweezers, remove and insert the jumpers at the appropriate
positions. Refer to Figure 2 for the jumper positions to select
Measurement Input and Analog Input.

1.3 Attaching to the Panel
Warning: Do not install the multicontroller in the following conditions:
∑Where the ambient temperature is higher than 50˚C (122˚F) or
lower than 0˚C (32˚F).
∑Where the relative humidity is lower than 20% or higher than 80%.
∑Where corrosive gas is generated.
∑Where strong vibrations and the potential for shock exist.
∑Where there is flooding or splashing of oil.
∑Where there is excessive dust.
∑Where there is any inductive disturbance which adversely affects
electrical instruments.

Procedure for Attaching to the Panel
1. Referring to the previous figures, cut as many square holes in
the panel as are needed for the number of controllers to be
installed.
Note: The panel thickness must be between 1 to 10 mm ( 0.04
to 0.4 inch).
2. Mount the controller into the cut from the front of the panel.
3. Insert one of the brackets shipped with the controller into the
slot on the top of the controller (see Figure 1).
4. With a Phillips head screwdriver, tighten the screw from the
rear of the bracket (see Figure 2).
When a gap is no longer seen between the panel and the
controller tighten one more full turn.
Be careful not to tighten too much, because the controller
case becomes distorted when overly tightened.
5. Repeat steps 3 and 4 to insert the other bracket on the bottom
of the controller and fasten it in place.

1.4 Wiring Procedure
Refer to the following "Wiring Precautions" and to "Terminal
Configuration" on page 14, to install the cabling.
Warning
Read the following precautions for selecting and wiring cables.
Improper wiring may cause unexpected, intermittent, or difficult-to-
analyze problems.
Wiring Precautions
1. For input and output signal wire (measurement input, analog input,
transmission output, and control output to the valve):
1.) Lay input and output cables as far as possible from power lines to
the controller or other equipment to avoid noise interference,
especially from inverter power lines as they are liable to produce
interference requiring countermeasures be taken on the inverter
side to suppress noise emission.
2.) Use an electrically isolated receiver when transmission outputs
are utilized. If the receiver is not an isolated type, the connection
must be made using an isolation amplifier.
3.) Use shielded cables for input and output signal cables.
4.) When using shielded cables, to prevent noise from being generated
due to floating capacity and the difference in grounding potential
between the cable core and shield, ground the shield as follows:
a. If the signal source is grounded, ground only the side closest
to the signal source.
b. If the signal source is not grounded, ground the controller side.

Signal source Controller

Signal source

12
SC-F70SC-F70 PID Operation Operating Instructions
2. For power lines
Wiring of the controller power source should be done so it will not
be affected by noise from power sources. When a source of noise is
nearby and the controller is affected by the noise, use a noise filter.
1.) Certain types of noise filter may not perform properly. Consider
the line voltage, filter frequency characteristics, and other things
before selecting a filter.
We recommend using the ZCB2203-11S filter, manufactured by
TDK.
2.) Be sure to mount noise filters on grounded panels, and use the
shortest cable possible between the noise filter output and
controller power terminal. A filter mounted on a longer cable may
be ineffective.
3.) When power cables and other cables for the controller are
adversely affected by noise, twist the power supply cables together.
The smaller the pitch, the greater effectiveness against noise.
4.) Do not install fuses, switches, or other such items on the cables
between the noise filter output and the controller power terminals,
because this may adversely affect filter performance.
3. For grounding
1.) Use only power cables that conform to local electrical codes.
To ground the controller, use cables with a nominal cross-
sectional area of 2.0 mm2(0.031 sq.in.) or more, use the same
contact point as the contact ground on the actuator, and ground in
the shortest possible distance.
2.) It will take about 3 seconds for the controller to prepare for
contact output when the power is turned on. When using the
controller to send a signal to an external interlock circuit or other
circuits, add a delay relay.

4. Other Precautions
1) Use M3.5 crimp terminals with insulating sleeves.
2) Use a time-lag fuse rated for 250 V, 1 A, if you install an external
fuse.
3) Refer to this wire specification table when selecting cables.

Terminal Configuration and Wiring
The next diagram shows a minimum configuration and its wiring.
This is the simplest configuration in which basic operations can be
performed; using the pressure transmitter MBS33M (from Danfoss
A/S) or the temperature sensor TR1 and the control valve CV10 or
CV16 shipped with the controller from TLV. (Other possible
connections are shown on page16.)
