2.4. FORMAT 550 DIGITAL CHANNELS The Format 550 programming system fitted to the cabinet has the following digital channel functions. A number of the channels are for the control of the cabinet and are usually automatically selected on or off by the programmer as required to achieve particular conditions. If applicable, other user designated channels are also detailed below. All digital channels are shown on the monitor and program screens of the Format 550 programmer.
DIGITAL CHANNEL 8 VOLTAGE FREE TERMINAL (VFT) USER PROGRAMMABLE CHANNEL This channel enables the switching of external devices, such as measuring equipment, and the test load. The system comprises of a voltage free termination of the programmer's digital channel number 8 which is wired through the cabinet's safety thermostat The final termination is a socket on the side or rear of the instrument compartment (a suitable plug is provided).
3.DESCRIPTI0N 3.1. PRINCIPLE AND AIRFLOW The well insulated cabinet interior is divided into working and treatment chambers, as shown in the diagram (fig. 1). Air is circulated by a fan from the treatment (conditioning) chamber into the working chamber through the right hand wall plenum in which the wet and dry bulb sensing elements are situated in the optimum position for rapid response.
3.2. TEMPERATURE CONTROL Accurate, repeatable temperature control levels are achieved by continuously balancing heat loss with intermittent modulated heating controlled by electronic controllers. The conditioned air flows over a dry platinum resistance temperature sensor (BS1904, lOOohms at 0°C) which feeds signals back to an electronic controller.
3.3. RELATIVE HUMIDITY (RH) Relative humidity is a measure of the ratio of the amount of water vapour present in an atmosphere to the amount of water vapour that atmosphere could hold, ie. Ihe humidity present relative to the humidity possible. The latter varies with temperature, hence RH measurements are related to their prevailing temperature. Air at 100% relative humidity is saturated and cannot absorb any more water.
3.3.4 RELATIVE HUMIDITY DECREASE Dehumidification is achieved using the cooling coil to form a dew point to remove water vapour from the air in the working chamber. The direct cooling mode has a low surface temperature cooling coil which enables dehumidification of the cabinet air between +5°C and +70°C.
4.INSTALLATION 4.1. ACCESSORIES & SPARES Check that the following items have been supplied with the cabinet. a) Wick for the wet bulb sensor(s) b) A set of psychrometric tables for the recorder (if fitted) c) Instructions and wick for recorder (if fitted) 4.2. POSITIONING 4.2.1 Cabinets not requiring on-site commissioning Place the cabinet on a level site, or suitable surface in the case of bench standing models, in such a position that air is free to circulate around it.
Figure 2 ^gomax.
4.3. AMBIENT TEMPERATURE IMPORTANT To achieve the guaranteed performance figures, the maximum acceptable laboratory ambient temperature is +25°C. At higher ambient temperatures, the minimum operating temperature and rate of fall will be affected.
Two small black plastic pipes are also fitted to the right hand side or rear of the cabinet. These are overflows from the wick reservoir and vpg humidification system self levelling header tanks. If a float valve develops a fault, the respective overflow will operate preventing flooding of the instrument compartment 4.7. DISTILLED WATER SUPPLY EITHER Connect the distilled water supply to inlet connector situated on the right side or at the rear of the cabinet.
4.10. CABLE PORT One or two cable portis are fitted to the left hand side of the cabinet to enable wiresAeads etc to pass into and out of the cabinet. The port has two plugs, one inside, one outside the cabinet and both plugs must be fitted when the cabinet is in operation to maintain the cabinets excellent insulation. The plugs can be slit or holes bored to enable wiresAeads to pass through the port.
5.0PERATI0N WARNING This cabinet is capable of temperatures well outside ambient. If the door is opened during such conditions there could be a temperature HAZARD from cabinet air or contents. 5.1. CONTROL PANEL INSTRUMENTATION Full details of the Format 550 programmer/controller fitted to the cabinet are given in Part 2. If there are any further controls not mentioned here, refer to 2.3 - Additional facilities fitted. 5.1.
5.2. CABINET AND PROGRAM START UP Ensure that: a) The interior of the cabinet is clean and dry. b) You know how to SHUT DOWN the cabinet (see section 5.4). c) Distilled water level is adequate d) Clean wicks are fitted to the wet bulb sensor(s). TO START THE CABINET: a) Switch the MAINS red/yellow isolator fitted to the front control panel to ON. The MAINS pushbutton on the front control panel will become illuminated green.
6.MAINTENANCE AND CARE WARNING Before entry into the instrument compartment, refrigeration compartment, or treatment chamber ISOLATE THE CABINET FROM MAINS POWER unless otherwise stated. The cabinet has been designed and built for a long life and requires minimal attention and maintenance. However, regular attention to the few points will ensure a long and trouble free life.
6.2. MAINTENANCE METHODS 6.2.1 Interior and exterior cleaning The cabinet interior and exterior should be kept clean and free from deposits. The exterior surface is easily cleaned with warm soapy water. When cleaning any stainless steel surface do not use any cleaning agent containing chloride or hypochlorite ions as these will cause corrosion. 6.2.2 Cleaning of cabinet drain(s) Either one or two drains are situated centrally in the base of the treatment chamber.
6.2.4 Lubrication Most moving parts are lubricated and sealed for life except, the inner door catches (if glass inner door is fitted). These components should be oiled once per month 6.2.5 Check safety thermostat Adjust the safety thermostat, sited inside the instrument compartment, through prevailing cabinet temperature. Check that the safety thermostat fails the cabinet safe. In the event of a fault RECTIFY AT ONCE. 6.2.

APPENDIX 2 REC/W - WATER SYSTEM The recirculating water system is a self-contained unit. The system purifies waste water from the working chamber and recirculates it back to the cabinet inlet, removing the need for a continuous supply of distilled water. It consists of a reservoir tank, water, pump, deioniser cartridge and a purity indicator.
System draining Switch off the main power. Disconnect the pipe connected to the cabinet distilled water inlet and place in suitable vessel or floor drain. Switch on the system, the pump operates and pumps out the reservoir water. When the water ceases, switch off the power and reconnect the outlet pipe to the cabinet distilled water inlet. Fill the reservoir with distilled water to the level shown on the sight tube.

1 .Introduction This section of the Operator's Handbook introduces you to the FORMAT controller, and also suggests how to use this handbook to best effect. 1.1. Introduction to FORMAT The FORMAT 550 SERIES programmer/controller is a powerful chamber control system offering advanced features such as data logging and program editing. The FORMAT 550 programmer represents the ultimate level of user friendliness in a dedicated test chamber controller/programmer.
1.3. How to use these instructions These instructions are written for the end user, and is not intended to be an engineering manual. For this reason it omits unnecessary detail concerning how the controller works, and concentrates on information the operator needs in order to make the best use of FORMAT'S powerful capabilities. Some users will find they are familiar with the system after only a short time.
2.Getting started This section describes the basics of using the controller and the meaning of the various items of information presented on the screen. 2.1. The menu system FORMAT uses a menu system to allow the operator to select what function the controller should perform. This approach will be familiar to users with experience of using personal computers.
2.2. Using the on-line help FORMAT has a context sensitive on-line help system activated by the Fl key. You can press the Fl key at any time while using the controller to obtain an information window summarising what actions are possible from the current position. The on-line help system is not intended to be a replacement for this handbook, but provides a useful reminder for keystrokes and menu options. If you find you are unsure of what to do next, your first action should be to call for the on-line help.
Information If however, you do wish to edit the digital channels, you should use the < and > keys. These keys do not skip the digital channel fields. When editing a program, if you use the "enter" key to move to the next field, the Digital Channel fields are skipped. This is because in most cases you would want to accept the suggested values prompted by the controller. 2.4.2 Types of data entry field There are two types of data entry field. The most common is a "value" field.
When running in program mode: Temperature is in °C, humidity is in %RH. A data segment, is a point in time when a change in the data on which the programmer is acting upon is required. - Times are specified as DAYS:HOURS:MINUTES:SECONDS. Each segment's time is from the start of the program. *"* The first segment of a program has zero time. Each segment thereafter must be sequential with time. The maximum number of segments in each program is 150. For digital channels 0 means OFF, 1 means ON.
3. Steady state control This section describes how to make the controller maintain a steady state condition. GENERAL OPERATING SEQUENCE - STEADY STATE MODE 1. 2. 3. 4. Select Steady State operation from the Main Menu Enter the required temperature setpoint. Enter the required humidity setpoint. FORMAT will suggest the correct digital channel selection. Set the digital channels for non-chamber dependent digital channels (VFTs, etc) as required.
3.2. Resetting steady state setpoints After you have entered a condition FORMAT will suggest digital channel settings. If you want to alter the suggested digital channel selections press "enter" (or "arrow right") key until the input cursor reaches the required field and press 1 or 0. Entering 1 switches a digital channel ON and 0 switches it OFF. When you are satisfied with the data in the window, press the F4 function key to start the chamber running.
3.4. Ending manual control To end steady state control press FIO. A safety catch message will ask you "Are you sure you wish to shut down" Note: this procedure terminates the FORMAT program, the cabinet should also be switched off by pressing the mains power pushbutton.
4, Programs This section describes how to write, edit and run programs on the FORMAT 550. 1. 2. 3. 4. 5. GENERAL OPERATING SEQUENCE - ENTERING A NEW PROGRAM Write out the program using the FORMAT program preparation sheets. Select Program from the Main Menu. Select New Program from the Program Menu. Enter the program, segment by segment. Save the program to disk. GENERAL OPERATING SEQUENCE - RUNNING A PROGRAM Select Program from the Main Menu. Select the Load from Disk from the Program Menu.

A segment can reflect any number of changes providing they are required at the same time. The first segment of any program starts at time 00:00:00:00 (days, hours, minutes, seconds). This corresponds to the instant the chamber starts running, at which time the condition inside the chamber is ambient. The segment time is from the start of the program not from the previous segment. The last segment's time must be the desired finish time of the program, c.
wherever the thermodynamic load looks large, increase the cooling power, typically from aux to main or indirect to direct cooloing wherever the required temperature fall rate is high, increase the cooling power wherever high humidity is required with a load that tends to dehumidify, increase the humidifier power. Usually this involves selecting first the high RH channel. Then the vpg instead of the atomiser. In extreme cases it involves switching them both on together.
4.5. Running a program When you choose Run Program from the Program Menu, provided the current program is valid, you will be presented with a data entry screen for run options. The options are: NUMBER OF CYCLES: This is the number of times the program is repeated. This facility is of use for repetitive programs. GUARANTEED SOAK: This option, when enabled, halts the program run time at each segment until the specified condition is reached.
4.6. Program Monitor Window When the run has started, you can observe the progress of the program by selecting the Monitoring option from the Main Menu. In addition to the information displayed for a Steady State ran, FORMAT displays the time into program run, number of program cycles left and the Time Hold mode.
4.8. Program completion When a program has been completed the Main Menu is displayed showing the program status as idle. 4.9. Program deletion Permanently deletes a single program. Select Delete Program, select the program to be deleted and press . 4.10.
5.Data Logging This section describes how to start and stop logging, and how to import data into industry standard spreadsheet packages.

The Logging Menu 5.1. Introduction to Data Logging Data Logging is selected from the Main Menu.
5.3. Stopping Data Logging To stop FORMAT data logging, select the Halt Logging Now option from the Logging Menu. 5.4. Displaying Results You can obtain a trend display of the data log from FORMAT using the Load Log From Disk option. This only displays the data in low detail. 5.5. Loading into Spreadsheets Data Logs in FORMAT are stored as "comma separated fields". Most industry standard spreadsheet packages support this data format for importing into them.
6.Alarms This section deals with setting alarms on the FORMAT controller. 6.1. Introduction to Alarms FORMAT provides a comprehensive array of alarm triggers. Alarms are available on fixed high and low setpoints, or on deviation from control set point. The same alarm functionality is provided for both temperature and humidity channels. Alarms can trigger several events: Shuts the chamber down. If you have set logging to start on alarm, data logging of the condition will start.
Set the alarm triggers by Enabling the relevant type of triggers, and then enter the threshold values for the triggers. You can have any combination of triggers enabled. If an alarm is triggered then "Alarm" is shown in the Status window and if logging is selected then the alarm condition is logged to disk.
7.C0MPUTER INTERFACING 7.1. INTRODUCTION Using the RS232 port on the chamber the Format 550 can be interfaced to PC compatible computers. Primarily there are at present two methods available to the user. However, this area of application continues to develop rapidly. If this manual does not fully address your application please contact SANYO Gallenkamp PLC or your dealer. 7.1.1 HOST SYSTEM This is a software package that can be installed onto the hard disk of apersonal computer.
Software Physical Components Installation disk Security key 7.2.1 INSTALLATION Insert the Installation Disk in drive A of the Host PC, and at the DOS prompt, enter the following: A: INSTALL The Host Software installation process will then begin. During installation, the Host Software is copied on to the Hard Disk, to a directory named \HOST. INSTALLING THE SECURITY KEY Before the Host Software can be used, the security key must be fitted.
HOST The Host Software will then start up in Network Monitoring Mode (see below). 7.2.3 NETWORK MONITORING MODE When the Format 550 Host software is executed, it scans the network for a Format 550 controller which is switched on and connected to the Host and enters Network Monitoring Mode. In this mode, the condition of up to 8 Format 550 Controllers may be seen on the screen of the Host PC. If there are no Controllers on the network (e.g. Host PC off-line), the condition panels are blank.
Countdown to Run Start (delay before starting a program) Monitoring The latter brings up a window which is identical to the monitoring window on the controller. If the controller stops running (i.e. the end of a program run or if Shut Down is pressed on the controller keypad), control passes back to the main menu. PROGRAM Selecting this menu option brings up a sub-menu: New Program - Clears program in Host memory and enters Edit mode. Edit Program - Allows program in Host memory to be edited.

7.3. Computer interactive interfacing: main protocol This section defines fully the serial communications protocol implemented in the Format 550 Controller used on Sanyo Gallenkamp chambers and rooms. This protocol allows a master computer (System Master) to communicate with one or more Controllers on a network.
7.3.3 PACKET LAYER DEFINITION Data Packet Structure Byte 1 2 Description Header Packet Count Serial No. Length S Data block length D Serial No. Data Block XOR Checksum Additive Checksum 3 4 5to(4 + S) (5 + S)to(4 + S+D) (5 + S + D) (6 + S + D) Byte Value range 128 to 255 0 to 127 1 to 127 1 to 127 32 to 127 0 to 127 0 to 127 0 to 127 Minimum packet size is 8 bytes. Maximum packet size is 260 bytes.
Data Block Length This is set to the number of data bytes which follow in this packet. The minimum value is 1, so if there are no data bytes, this should be set to 1 and the data block should contain a single null byte (value 0). Serial Number In Command Packets this field contains the serial number of the Controller to which the packet is intended, encoded in ASCII. In Reply Packets, this field contains the serial number of the Controller transmitting the Reply Packet.
The Controller has buffered interrupt driven communications. This ensures that Command Packets from the master cannot be lost even if the Controller's processor is preoccupied with another task. If the Controller's processor is preoccupied, however (e.g. accessing the disk or repainting an area of the screen), the Controller will not issue the Reply Packet immediately. The master should allow the Controller up to 12 seconds to reply.

Only ONE file may be opened at a time. The master should take some special precautions before issuing this command. Firstly, to ensure that no file activity takes place on the Controller during the file transfer, the master should send a Set Controller to Remote Access Mode command packet (see below). This locks out the keyboard on the Controller. - Next, the master should use a Status Request command to ascertain the data entry mode of the Controller. - If the Controller is in Engineering, opening a .
Description Type Source Header Data Block READ DATA Reply Controller 133 Even number up to 126 bytes Data block contains up to 63 hextuples representing the next block of data from the file. For example, the sequence of bytes 4Ah, 80h, 25h, 30h would appear in the data block as the string "4A802530". If the Controller has no more bytes to send, a data block of one null byte is transmitted by the Controller.

7.5. Support software Because this is a rapidly developing aspect of the applications of Format 550, S ANYO Gallenkamp PLC continue to expand the range of support available for these systems. If your application is not covered here, please contact our Service dept or your dealer. Applications currently being explored include simple routines to interrogate the chamber in terms of temperature & humidity, potentially to be available in B. A.S.I.C. source code and as compiled .EXE files.
APPENDIX 1 - TECHNICAL SPECIFICATION Temperature & Humidity Programmer/Controller with inbuilt Logic, chamber intelligence mapping, & Data Logging Operator interface data entry: on-chamber dedicated numeric keypad, display: on-chamber (green) monochrome CRT. Operating temperature: 5°C to 60°C. Analogue inputs Two 4 wire PRT inputs. Range -150°C to +350°C. Accuracy +/0.1°C. Dedicated to measuring temperature and humidity (relative humidity is derived by wet & dry bulb by psychrometric computation).
Program Run Options Repeats: up to 9999 cycles Guaranteed Soak: active:at start of each program segment arming: preset at run start, or manually during program run criteria: temperature error 0.5oC, or relative humidity error 1% action: program time base is arrested until the condition returns inside limits. Run start facilities: in-cycle start (specify time into first cycle) delayed start (allows unsupervised start).
APPENDIX 2 - PROGRAM LOOPING AND NESTED LOOPS You can program loops in format550. In addition you can program loops within loops (nesting). This section tells you how, with simple examples. LOOP INSTRUCTIONS The loop instructions are achieved using the "LS" & "Rep" columns that appear on the program preparation sheet & on the program window of the system. In the line from which you want to loop back: in column "LS" you specify which line you want the program to loop back to.
When you run this program you will see that it causes the temperature to return to 25°C (point 6 in the diagram) at 3 minutes after the start of the cycle, not at 1 minute 40 seconds as listed. This is because the looping interferes with Format 550's timekeeping. Due to the disruption of the internal timekeeping, the listing of events that succeed loops is no longer derived directly from the start of the cycle.
EFFECTS ON THE RUNNING TIMEBASE DISPLAY The timebase display in Monitor mode no longer counts up time from start of cycle after the system starts to loop. Once it passes the point from which it must loop back, it displays the time flow within each loop. Once it has finished looping it continues to count up time from the beginning of the last loop. The need for calculation can be removed by changing the basis of timing to a segmental one, but it is no panacea.
(segment 5 is the first segment looped back FROM) time from segment 2 to segment 5 60 seconds = 1:20 loop 1 from 5 to 3 40 seconds time from 3 to 5 loop 2 from 5 to 3 80 seconds time from 3 to 7 loop A from 7 to 2 60 seconds time from 2 to 5 loop la from 5 to 3 40 seconds time from 3 to 5 loop 2a from 5 to 3 80 seconds time from 3 to 7 loop B from 7 to 2 60 seconds time from 2 to 5 loop lb from 5 to 3 40 seconds time from 3 to 5 loop 2b from 5 to 3 40 seconds time from 3 to 5 total 500 s
