Pressure Control 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:

∑Pressure control (These operating instructions)

∑Temperature control

∑Auto-tuning PID control/ heating, cooling PID 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 pressure control.

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.

The 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.

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. Measurement input uses current mode, or the sensor to be used is a

Danfoss type MBS33M 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 no gap is 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 13, 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.
