1 Installation Information

1.1 Power Up

When power is connected to the EDAC700 RTU it will beep continuously for a short

time. During this time it will display “RUN_” on the LCD. The beeper will then stop and

the display will show a code version number like 1.4.3p under the word RUN_, for a

short time.

Note! This version number is required if you need to make any technical support calls.

After this the EDAC700 RTU goes into Run Mode and displays the Run Mode Display.

If it does anything different to this sequence and does not end up at the Run Mode

display, power it down completely, and start again, or press the Reset button located in

the top right corner.

If the battery is not connected, the EDAC700 RTU may generate a low battery alarm,

and will ask for a PIN. If this happens, connect the battery and check the supply voltage.

Press the Reset button to start again.

Note: The RS232

port here faces out

the right hand side of

the box. When

securing to a wall

allow about 50mm

(2”) extra room for

the serial plug &

lead.

1.2 RS232 Connection

At this point you can have an option to work from either the EDAC700 RTU keypad or

from a PC via the RS232 port. You can use almost any Terminal emulator program,

however EDAC supports the use of Windows Hyperterm for this purpose, and this is fully

documented in the next section.

The instructions in this manual are illustrated using images of the EDAC700 RTU

keypad, but the RS232 connection can be used for almost all the processes shown. The

terminal menu closely resembles the LCD displays. The menus are shown with a letter

alongside each choice, so pressing the letter is equivalent to pressing <Ok> on a choice

on the EDAC700 RTU keypad.

A combination of the keypad and the PC terminal can even be used simultaneously until

you are familiar with the menu system via the PC program. It is always best to record

voice messages while using the EDAC700 RTU keypad.

2 Hyperterm and the EDAC700 RTU

Microsoft provides Hyperterm free with all Windows operating systems from Win95 on.

If it is not installed you can normally find it on the Windows distribution disk.

Once your terminal program is connected to the EDAC700 RTU and the RTU is in

Program Mode, the complete menu is displayed on the PC screen with a letter for each

option. Typing each letter selects the corresponding option.

2.1 Direct RS232 Connection Configuration

This screen capture shows how Hyperterm should be configured to make a direct

connection via Com1 and RS232 lead.

This next screen capture shows the settings form for the Communications Port that is

displayed when you click on Configure. Enter all the values as they are listed here.

Use drop down

Use Configure

Button to get to

Hyperterm provides a facility to save connection settings to an Icon/File. Once saved the

Icon/File can be clicked to start the connection to that site name. E.g. You could save a

direct connection as “Com1 19200bps”

NOTE: The EDAC 700 RTU will not respond to Hyperterm unless it is in Program Mode.

A PIN number (default =0000) must be entered via the EDAC700 RTU keypad, after

Hyperterm is started, to put the EDAC700 RTU into Program Mode. This will allow

communications to take place.

When Hyperterm is configured correctly, and the Program Mode PIN is entered via the

EDAC 700 Keypad, you should see the above menu in the Hyperterm window.

2.2 Modem Connection Configuration

NOTE: This type of connection should only be done after experience with a direct RS232

connection

This screen capture shows how Hyperterm should be configured to make a remote

modem connection. Replace the ‘709’ number with the required phone number. The

‘….5.0005’ is required to establish a modem connection.

Making a connection

Once the connection information is configured and saved you can double click the

Icon/File and a window will open allowing you to initiate dialling to the pre-configured

site.

When a connection to the EDAC700 RTU is established via a modem connection, the

PIN to put the product into Program-Mode is not required. The EDAC700 RTU will go

into Program Mode automatically.

3 Physical Sensor Wiring and Measurements

The EDAC700 RTU has 20 physical input/output (I/O) terminals. The following diagrams

show how the circuits around each of the I/O terminals are configured to perform each of

the six functions.

3.1 Digital Input - Normally Open

Normally open and normally closed inputs have a 0-10V input range.

Normally Open, clean contact, input to Com/Gnd. Triggers below ~1.5V.

3.2 Digital Input – Normally Closed

Normally Closed, clean contact, input at Com/Gnd. Triggers above ~1.5V.

3.5 Analogue Configuration

3.5.1 Sensor Calibration

Sensors are calibrated by providing two sets of coordinates (4 values) from a graph,

from these coordinates the slope of the graph can be calculated, this is also called the

multiplier (M).

Reading in Engineering units (Y) = multiplier (M) * sensor reading in mA/Volts (X) +

offset (C )

By making fine adjustments of the set points and using an external calibration reference

we can calibrate the sensor.

3.5.2 Calibration Example 1

You may have trouble doing fine adjustment of slope, by adjusting the high or low

calibration points. The EDAC700 RTU may give you the impression that it does not use

the decimal component of the value entered, making it feel like it has quite coarse

control over calibration values. The EDAC700 RTU actually uses 5 decimal places more

than the decimal places entered in the calibration values. Therefore entering 3.12 will

cause the EDAC700 RTU to use a value of 3.1200000 and entering 3.1234 will mean

3.123400000 is used.

The formula for calibration of slope is:

mA x steps x multiplier = display value (assume offset =0) & V x steps x multi = display

value

where steps 1V = 4095, mA = 4095/20

eg at 1:1 becomes: 20mA x 4095/20 x 0.004884 = 20

To calibrate the multiplier:

1. Set up reading as desired with low/high mA and Eng units

2. Read the display. (D1) eg 19.5

3. Note the expected display (D2) eg 20.0

4. Calculate correction factor D2/D1 (20.0/19.5 = 1.025)

5. Adjust mA high value by correction factor HmA x D2/D1 (20 x 1.025 = 20.51)

6. The display should now read as expected.

C=Offset

Y=Eng Units

Hi Eng

= 100%

Low Eng

= 0%

Y = M * X + C

X = mA

Low Value

= 4mA

High Value

= 20mA
