Section 1 - Instrument Overview

The CCD104 is amulti featured process display controller, designed to be flexible, able to

adapt for use in many processes. It is mainly based upon Chell’s signal channel display

controller, the CCD100 and shares most of its features, but for multiple channels. This is

the second generation of the Chell CCD104

The CCD104 has four main channels. These can be used to operate flow controllers or

display the output from pressure transducers. The CCD104 also has the ability to power

these devices with either +/-15dc or +24vdc.

Interfaces to the CCD104 include Ethernet, RS232 (via USB) or it can be used with just

analogue signals.

Note: This manual has been written for firmware version 1.00.

Section 3 - Installation and Interconnections

The instrument is designed to be rack mounted (see drawing on next page for panel cut-

out). Note that the instrument must always be situated in such away as to enable

adequate air circulation about the unit.

If a transducer was supplied with the CCD104 a suitable cable may have been included.

3.1 Transducer socket Pinout - 15 Way 'D' Type (x4)

Pin Number Designation

2 Signal High

5 0V Power

6 -15V Supply Output

7 +15V Supply Output

8 Command Output (V)

9 Command Output (mA)

12 Signal Low (0V Signal)

15 Earth/Chassis

All other pins Not Connected

If the transducer is being powered from another source (e.g. amains powered supply) it

will only be necessary to connect to the two signal pins.

Note: The CCD104 has afully floating differential input. For single ended use (i.e.

tranducers with adifferential output) join 0V Power (pin 5) and Signal Low (pin 12) at the

transducer.

3.3 USB Connector – USB Type-C

The connector supports USB-C 2.0 cables without the SuperSpeed pairs. Therefore

connecting afully featured USB-C 3.1 cable will not provide SuperSpeed functionality,

although the cable will still work as per the USB 2.0 specification.

USB is provided for legacy serial data comms and debugging purposes.

Cautions: 1. Ensure correct mains supply rating and polarity.

2. Instrument must always be earthed.

3. Instrument must not be used when faulty, wet or

near water.

Section 4 - Front Panel Operation

4.1 Introduction

The front panel consists of a480x272 TFT LCD colour display with acapacitive touch

membrane consisting of 11 ‘switches’ and a‘scroll wheel’. Each switch has legends on it

(and in some cases above it) to indicate the function of the switch. Most switches have

some commonality between different screens, as detailed below.

For the purpose of the following sub-sections, the switches shall be referred to using the

legends on the membrane.

4.2 Common Switch Functions

The switches on certain types of screens and in certain modes, have the same functionality

as detailed here:

(a) Menu screens

On all menu screens, the scroll wheel is used to navigate through the menu options.

The ‘Func’switch is used to go back to the parent menu, except on the Main Menu

screen where it goes back to the main screen. The ‘Enter’ switch actions the

chosen menu selection to an editable or information screen (see HMI breakdown for

more details).

(b) Editable screens

On any screen that has editable fields, the scroll wheel will move the selection

between the possible editable fields. ‘Func’goes back to the parent screen which is

usually the menu that was used to get to the screen in question. ‘Enter’ activates

edit mode (see below).

When in edit mode, the edit cursor appears on the first character in the editable field

(the cursor is an inverted box over the character being edited). If the field is bigger

than 1character then switches ‘ ’&‘►’are used to move left and right across the

field. If the field is only one character (e.g. aYes/No selection) or has arolling

selection (e.g. for selection of a percentage) then ‘ ’ & ‘►’ do nothing.

The wheel is used to change the character being edited within the valid range (field

position dependant). ‘Func’cancels edit mode and returns the field to its previous

value. ‘Enter’ accepts any changes to the field and also comes out of edit mode.

4.3 HMI breakdown

Here follows a complete breakdown of all screens that appear whilst using the CCD104:

(a) Main Screen

The main screen shows the currently enabled input data (with range, full-scale and

calibration applied). Each channel can be assigned alabel (‘Chx’ above) and aunits

string. These are fully configurable in the Configuration sub-menu screens (see

later). If an input is over range (more than 15% above full scale voltage) then the

data value is replaced with the over range error –“RANGE”. Also shown is the

current mode of the setpoint, if it’s not in AUTO mode (i.e. OPEN or CLOSED). If the

relay has been tripped (i.e. the input has gone above the configurable threshold)

then a small bar is shown on the far left of the screen next to the channel label.

When achannel is selected, its associated label is highlighted (as shown above on

channel 4). This selection is cleared automatically when avalid function is selected

(e.g setpoint mode change), or after 5seconds have passed if no function is

selected.

If asetpoint value is being changed, the channel selected splits into two lines, the

bottom showing the input data and the top showing the setpoint as it is being

altered (as shown above on channel 4). The caret above the Setpoint value is

moved through the decades by the ‘ ’ or the ‘►’ switches.

Switch Functions:

Func No function

No function (in normal operation)

Moves decade caret left (when changing setpoint)

Rezero selected channel(s) (if held)

►Select all 4 channels (in normal operation)

Moves caret right (when changing setpoint)

‘Wheel’ Change setpoint value of selected channel

Ch1 to Ch4 Select Channel 1 to 4 (only one channel at a time)

Open, Auto, Close Change setpoint mode of selected channel(s) to OPEN,

AUTO or CLOSE

Enter Enter the menu system
