Section 1 - Instrument Overview

The CCD100 is amulti featured process display controller, capable of interfacing directly to

amass flowmeter or other process transducers. This is thethird generation of the Chell

CCD100 display.

The CCD100 is asingle channel unit which can be used to operate aflow controller or

display the output from apressure transducer. It supports both voltage transducers

(typically 5&10Vfull scale) and also millivolttransducers (max 250mV full scale). Thereis

also asecondary channel which can be used for external command (setpoint) control

(+10v full scale). TheCCD100 also hasthe ability to power such devices with either ±15dc

@ 250mA or +24vdc@ 300mA.

Interfaces to the CCD100 include RS232 (via USB), Ethernet or itcan 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 panel mounted, and is astandard96x48mm panel meter

enclosure. Note that the instrument must always be situated insuch away as toenable

adequate air circulation about the unit.

If a transducer wassupplied withthe CCD100 a suitable cable mayhave been included.

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

will only be necessary to connectto the twosignal pins.

Note: The CCD100 has afully floating differential input.For single ended use (i.e.

tranducers withdifferential output) join0V (pin5) & Signal Return (pin12) at the transducer.

3.3 USB Connector – USB Type-C

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

connecting afully featured USB-C 3.1 cable willnot 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.

3.4 Power Connection Socket

The panel meter display requires a24V, 500mA supplyto operate. This must bearectified

and regulated directcurrent supply, capable of 15W(recommended). Although the

CCD100 has an internal fuse and power supply overload shut-downprotection the supply

to the CCD100 should be protected by fuse or other suitable electronic method.

A standard5mm diameter ‘dc power jack’ is required toconnectto the CCD100.

Connect the positive conductor to the centrepin. Connect the negative (0V) conductor to

the outer of the jack.

If requested, acompatible AC-DC switch mode power supply willhave been supplied with

the unit.

Cautions:

Ensure correct power supply rating and polarity.

Do not use a partially assembled or faulty unit.

Incorrect use of this equipment, or use in a manner not specified may

impair the users protection.

3.5 Panel Mounting

A panel mount kit will have been supplied with the instrument. This consists of:

2 M3x6 screws. 2 brackets. 2 50mm screws.

Fit the M3x6 screws into the side of the unit into the diagonally opposed holes. Do not

tighten these screws, to allow the bracket toslide over the screw head. Thread locking

adhesive may be used but is notrequiredasthese screws cannot rotate once the bracket

is tightened.

Insert the meter into the panel. A hole cut-outof 92 x45mm is recommended.

Slip the mounting bracket over the screwhead andtighten the 50mm screw.

The unit should now be secure.

Section 4 - Front Panel Operation

4.1 Introduction

The front panel consists of a128x32 pixel monochrome graphicOLED display with 6

membrane key switches below it. Eachswitch has legends on and above or below it to

indicate its function under different conditions, although thereare certain common

functions toeach screen, as detailedbelow.

For the purpose of the following sub-sections, the switchesshallbe referred to using the

legends on the buttons.

4.2 Common Switch Functions

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

as detailed here:

(a) Menu screens

On the menu screen, the ‘ ’&‘▼’switches are used to navigate through the menu

options. The ‘Func’switch is used to go back to the main screen.The ‘Zero’switch

doubles up as an Enter switch and this actions the chosenmenuselection. This

may be to go to asub-menu or to an editable or information screen (see HMI

breakdown for more details).

(b) Editable screens

On any screen that has editable fields,switches ‘ ’&‘▼’move the selection

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

usually themenuthat was used to get to the screen in question. ‘Zero’activates edit

mode (see below).

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

(the cursor is ahorizontal bar below the character being edited). If the field is bigger

than 1character then switches ‘◄’&‘►’areused to moveleft andright across the

field. Ifthe fieldis only one character (e.g.aYes/Noselection) or has arolling

selection (e.g. for selection of apercentage) then ‘◄’&‘►’do nothing. Switches

‘’&‘▼’are used to change the character being edited within thevalid range (field

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

value. ‘Zero’accepts any changes to the fieldand also comes out of edit mode.

4.3 HMI breakdown

Here follows a complete breakdown of all CCD100 screens:

(a) Main Screen (not changing Setpoint)

The main screen shows the main channelinput data(with range, full-scale and

calibration applied) and the associatedunitsstring. If aninput is over range (more

than 15% above full scale voltage) then the data value is replaced with the over

range error –“RANGE”. This screen also shows the current mode of the setpoint, if

not in AUTO (i.e. OPEN or CLOSE). If eitherof the relays have been tripped then

they are also indicatedas such on the farright of the screen.

Switch Functions:

*By default theFunc switch does nothing, butspecial builds ofthe CCD100 may includefunctionality for this

switch. In such cases an addendum to this manual will indicate the function.

(b) Main Screen (changingSetpoint)

When performing alivesetpoint change, the main screenis aspreviously, but with

the addition of the current setpoint value (initiated viaan initial press of the ‘ ’or

‘▼’switches). Note that the setpoint valueis not permanent –ifthe ‘ ’or‘▼’

switches are not pressed at all for 3seconds,then the setpoint value disappears.
