Page 7

Important safety information

 The device must always be protected against wetness and mois-

ture. Under no circumstances may it be exposed to splashed water or condensate.

 Surge category II  Soiling degree II

Requirements of cable for mains voltage and system components and installed lines

Use only cables and installed lines which meet the following requirements:

 Dielectric strength 30 V … 260 V according to the nominal voltage

(see specification plate)

 The cable ducts installed by Gebr. Heyl in the device have a

clamping range of 4.5 mm – 10 mm. This means that the external diameter of the laid cable must remain within the range of 4.5 mm – 10 mm. If you use other ducts, the cable diameters must correspond to the ducts.

 The terminal strips on the circuit board require core cross-sections

of between 0.08 mm2 and 2.5 mm2. This applies to single-wire and fine-wire cores with wire end ferrules without plastic collar. For fine-wire cores with wire end ferrules and plastic collar, the cross-section may be up to 1.5 mm2. For single-wire cores, AWG28 – AWG12 can also be used.

Optimum cross-section of the cores

If the core cross-section is less than 0.5 mm2, jamming may occur when the cores are loosened from the terminal strip. We therefore recommend using wires with cross-sections greater than 0.5 mm2.

Requirements for cable ducts

 The recesses in the housing are intended for M16 ducts.  The ducts should have a smooth and rounded opening (to protect

against bending and abrasion).

 Be careful to ensure securely fastened bending protection, which

must be five times the length of the maximum cable diameter.

 The duct should include a strain relief that prevents slippage of the

cable and that cannot be disengaged without a tool.

 You can order cable ducts from us as spare parts (Spare parts and

accessories).

If you use another cable duct, the material must have a flammability rating of V1 or better.

NOTE

Page 8

Important safety information

During assembly

 Always disconnect the relevant system component from the power

source before assembling the device or connecting it to the power supply or disconnecting it from the same. Prevent any inadvertent reactivation of the device.

 Only connect the device to the mains voltage as specified on the

type plate.

 Observe the technical data and the environmental parameters.  The connections for mains voltage and relay outputs must be laid

separately from each other, to guarantee corresponding insulation between the cables. Accordingly, do not operate the device if the partition walls or terminal area covers are not present.

Avoiding interference voltages

The Testomat® EVO TH device requires stable and uninterrupted supply voltage. Where applicable, use a mains filter to shield the Testomat® EVO TH device from interference voltages, which may be generated for example within the network by magnetic valves or large-scale engines. Never lay the connecting cables in parallel to mains cables.

Handling may cause damage or destruction of electrical components!

If you need to open the upper door, you should take the necessary safety measures to avoid electrostatic discharge onto the components (ESD safety).

Make sure you are earthed before opening the casing.

During operation

 The device has no power switch.

Use an external power switch to turn the unit on and off. The switch must be installed next to the device and must be marked as power switch for the device - for example with a label.

 Ensure that the maximum electrical load capacity of the switching

outputs is not exceeded, particularly for inductive loads. The power supply for the user inclusive device is secured with a 4A fuse, which means the total of all loads must not reach 4A.

 In the event of any malfunctions, immediately switch off the Tes-

tomat® EVO TH device and inform the service personnel. Never attemt to repair the Testomat® EVO TH device yourself. Doing do will invalidate the guarantee. Repairs must be performed by authorized service personnel only.

Important safety information

During cleaning

 Only use a dry and lint-free cloth.  Maintenance and care instructions are included in the section

"Servicing and maintenance” and in the Testomat® EVO TH maintenance manual

Malfunctions/repairing a defective device

 A defective device, regardless of the guarantee period, can be

serviced only when the device is dismantled and the error is described. Please also inform us of the indicator type currently in use and the measured medium. Make no changes or modifications to the device that go beyond the scope of use specified in these instructions. Doing so will void the warranty. This applies particularly to the measuring chamber, the seal of which must remain undamaged. If you send the device in for repair, please completely empty the measuring chamber and remove the indicator bottle and the drain funnel. Also remove the power pack and send it back in the original packaging. Before dismantling, the type of error must be noted (error number, error effect, log file of the SD card).

 Once a protective device has been triggered (safety fuse), initially

try resolving the cause of error (e.g. by replacing a defective valve), before reactivating the protective device. Frequent triggering always signifies an error, which under certain circumstances may also damage the device.

 Before sending the device in for maintenance or repair, pack-

age the power pack individually in the original box in which it was delivered. If the original packaging is no longer available, package the power pack to prevent breakage.

During disposal

 Dispose of the device in accordance with the regulations of your

country.

Important safety information

Operating requirements

 Problem-free operation of the Testomat

device is only possible

when using Heyl Testomat indicators and only within the pH range of 4 – 10.5! Using external indicators may invalidate the guarantee.

 Only operate the device within the scope of parameters specified

under "Technical Data".

 For Testomat® devices used to monitor water hardness, large

quantities of heavy metal ions in the hardened water may disturb the color reaction, particularly

o Iron over 0.5 mg/I o Copper over 0.1 mg/I o Aluminum over 0.1 mg/l (brown-red color indication).

 If the test water contains more than 20 mg/I CO2 (carbonic acid),

erroneous evaluations cannot be ruled out. In this case, use an irrigator (e.g. optional accessory from Heyl Co.).

 The water to be measured must be clean and free of bubbles!  The concentrations of disruptive ingredients can be determined

with colorimetric TESTOVAL® test comparators from Heyl Co.

 In the event of

o excessive carbonate hardness o the presence of disinfecting agents o the presence of silicate (used to protect pipes), the measur-

ing chamber may become soiled, which over time

may lead to erroneous evaluations  Careful handling of the device enhances the operational safety and

the service life! With this in mind, perform a visual inspection of the device at regular intervals as follows:

o Has the expiry date of the indicator elapsed? o Are the hose connections of the dosing pump leakproof? o Is there any air in the dosing hoses? o Are all water connections leakproof? o Is the door of the device carefully closed? o Is the device excessively soiled? o Are the measuring chamber and drain channel/drain hose

clean?

 Problem-free operation is contingent on regular maintenance!

Maintenance and care instructions can be found in the "Servicing

and maintenance" section.

 Indications of problems can be found in the "Error messag-

es/troubleshooting" section.

Cable ducting

To guarantee IP protection, the device is supplied with cable ductings and blanking plugs. If you wish to use a relay output, you must remove the blanking plug from the cable ducting.

Proceed as follows in this instance:

 Loosen the strain relief of the cable ducting (union nut).  Take out the blanking plug and insert the cable.  Tighten the union nut of the cable ducting and so establish the

strain relief.

Install power supply board and connect mains voltage

Installing the terminal compartment cover

For technical safety reasons, the terminal compartment cover must be put back in place immediately after connecting the mains voltage and the system components, since the terminal space houses cables that carry dangerous voltages. This helps prevent inadvertent contact with the terminals and contact between the individual lines that may carry different voltages and thus avoid the risk of a life-threatening electric shock.

Also ensure that the cables are not pinched when installing the terminal compartment cover!

Connect the device only to the mains voltage for which it is designed. See type plate to confirm the suitable mains voltage. To connect the cable, please proceed as described below:

 Remove both fixing screws  and open the upper door.  Remove the power supply board from the box at the bottom of the

housing.

 Insert the power supply board into the slot on the mainboard.  Screw in the two fastening screws at the top and bottom of the

mainboard.

 Remove the fixing screws of the terminal cover and then remove

the terminal cover itself.

 Lay the cable through the cable ducting provided for that purpose.

Limit value monitoring

You can program the limit values to be stepless. The limit value range is specified by the indicator type and programmed unit used. You can monitor two limit values. For this purpose, each limit value output is available. The functions of the assigned delay outputs can be programmed independently of each other.

The limit value outputs are permanently assigned to limit values! (GW1/2 are available on the LV1/2 terminals.)

LV1 = limit value 1 LV2 = limit value 2

If the limit value LV1 is exceeded, the limit value control indicator lights up in RED and the relay output LV1 responds according to the programmed switching function. If the limit value has not been exceeded, the indicator lights up in GREEN. The same functional approach applies to the limit value LV2.

Limit value operating mode

A limit value may be defined for both relays. The relay switches when the limit value is exceeded.

Two-point operating mode (Output LV2 relay as a two-point controller)

If the LV2 upper limit value is exceeded, the LV2 output relay is activated. If the lower limit value LV1 is not attained, the LV2 relay is switched off. Different values must accordingly be set for the limit values LV1 and LV2. For example, for LV1 = 0.1 °dH and LV2 = 0.2 °dH. The Output LV1 relay works independently as a limit value relay and is activated once the LV1 limit value is exceeded.

 Input the time (only with impulse and interval switching function)

(Values from 00:00 up to 99 min. and 99 sec. can be entered)

 Confirm the input with "OK"

Switching function only after multiple exceeding of limit value

The respective limit value output can be set to be triggered after the first, second or third exceeding of the limit value.

This improves the assessment of the analysis e.g. after possibly insufficient purging of the sampling line.

The value may be separately configured for both the LV1 relay and LV2.

The basic setting is 1 for LV1 and LV2. Switching occurs immediately after the limit value is exceeded, with no delay.

When the number of times the limit value has been exceeded is “2”,

the next analysis is performed immediately after the first exceeding of the limit value. Only after the limit value has been exceeded twice is the corresponding output switched.

When the limit value has been exceeded “3” times, the corresponding

output only switches after the limit value has been exceeded three times consecutively. This setting is only reactivated once the reading falls under the limit value!

Switching function duration

If the limit value LV1 or LV2 is exceeded, the output LV1 relay or LV2 switches. If the limit value LV1 or LV2 is not attained, the corresponding relay is again deactivated.

Switching function impulse

If the LV1 or LV2 limit value is exceeded, the corresponding output switches for the set time (t).

Regardless of the duration for which the limit value is exceeded, the corresponding output remains always switched for the set time. A renewed impulse is possible only once the reading falls under the limit value!

Input purge cycle

To guarantee that the sample being analyzed is current, the sampling line must be sufficiently purged over its entire length. When the system is unused for an extended period and when the analysis interval is considerable, a purge cycle of more than 60 seconds should be selected. The purging is performed by simultaneously opening the inlet and outlet valves of the Testomat® EVO TH.

BOB operation (operation without constant supervision)

The operation without constant supervision is safety-relevant when using the device to determine water hardness and monitor steam boiler systems in accordance with TRD 604.

If the BOB function is programmed, the device continuously checks the available quantity of indicator.A calculation using the following data is performed to determine whether sufficient indicator exists for the next 72 h: purge cycles, current indicator fill level, interval pause set, and the average measurement value of the previous 10 measurements.

indefinitely activated (terminals 10 - 12 closed), pending resolution of the error. The prerequisite here is that, in the menu => Basic program => Alarm/Message

the signaling "A" indicating the alarm for this error type is activated.

- The fault signal at the "Alarm" output is stopped when you

acknowledge the error with the "horn" button or by entering EXT. ACK. With the help of these inputs and outputs and the transmission of measurement data (via 20mA current loop or serial RS232 interface), the Testomat can be operated at a master display.

- If the limit value is exceeded, there is no additional Alarm via the

Fault signal output!

A description of the possible causes of error is included in the section on Error messages/troubleshooting.

Alarm/message – How to proceed when errors occur

Error messages are adapted to the selected language, but can also be identified by an error number, regardless of the language used.

All errors are, regardless of the settings made in this menu option:

- stored on SD card if Storing of error messages has been activated

- recorded in the error history (the last 20 error messages)

- and sent via the serial RS232 interface.

Detailed information on possible error messages as well as their cause and remedy is found in Error messages / trouble-

shooting.

Water shortage

The water shortage error is a special case, since one further setting can be configured for this error. In the menu, under => Basic program => Waterlow count the number of consecutively occurring errors before the alarm is triggered can be set. An error is then generated for each measurement cycle.

Number of water shortage errors

This function is specially provided for systems subject to intermittent low water pressure errors, which trigger a "Water low" error in the device. The number 0 can be set for an immediate message, or the setting can be raised to 250 occurrences before the error alert is sent.

Switching of the signal inputs

 Switch the signal inputs "Stop", "WM" and "Ext. Ack" only with

isolated contacts! Switching with external voltage will damage the device!

Stop input

The stop input is intended for short-term suspension of operation, e.g. when performing renewal work on softening plants, reverse osmosis or other water treatment systems. Generally speaking, the system is not offline for more than six hours. The renewal phase of a softening plant, for example, lasts three hours at most.

Where the contact is opened or closed at the input, no analyses are performed

If stop input is active, an analysis is prevented from starting, due for example to an interval having elapsed. This may be required, if the system lacks water. However, any analysis already started will not be suspended. The analysis is completed and the device reverts to pause mode. Manual start has priority over stop input. That means that manual analysis can still be started even when stop input is active. Where the stop signal is present, the measurement value is shown on the display and the LED pause flashes. If the stop signal is deleted, a new analysis starts immediately. Accordingly, a short impulse on the stop input can help trigger an analysis remotely.

Monitoring the measurement point

Connecting a recorder allows the analytical results to be documented. For this purpose the device includes a programmable current output (optionally 0-20 mA or 4-20 mA).

The following example indicates the course of the current within the range of 0-20 mA.

 Select in the menu

=>basic program => current interface type

 Select the desired current range.  Confirm the selection with "OK"

Calculation of output currents

Depending on the selected function, the current range available is either 0 – 20 mA or 4 – 20 mA. The resulting currents for the various measurement values are shown in the form of the following formulas.

Measurement value Current = x 20 mA Measurement range upper limit

measurement value current = x 16 mA + 4 mA Measurement range upper limit

The current is set to 0 or 4 mA.

The current is set to 20 mA.

Serial interface

The serial RS232 interface transfers measurement data and alarms/notifications in plain text/ASCII in CSV format. It is always active. The baud rate can be set to 2400, 9600, 19200, 38400 and

115200. Transmission is in the 8 bit format, 2 stop bits, no parity. A new measurement value is transmitted as soon as it has been de-

termined.

 Select in the menu

rate

 Select the desired baud rate.  Confirm the selection with "OK"

New alarms are transmitted via the serial interface and some alarms even when the alarm has been ended; see Error messag-

es/troubleshooting.

Notification format

The notifications are sent in a very similar format as the data placed on the SD card:

 The headings are not transmitted  Field separator is a comma  Decimal separator is a full stop  Each data set is started with the ASCII characters “02”

<STX> and terminated with “03” <ETX>.

 Notifications and measured values can be distinguished by

evaluating the first characters: If “ME” is read, it is a meas- ured value; with “AL”, it is an alarm/notification.

 This corresponds to the format of the Testomat 2000® data

logger.

Example of measured value:

<STX>ME,TH2005,31.07.2013,08:09,0.050,°dH,limit val.1:,0.200,°dH,limit val.2:,0.300,°dH<ETX>

Examples of notifications:

<STX>AL,Power failure,01.08.2013,06:30<ETX> <STX>AL,turbidity,01.08.2013,07:30<ETX>

<STX>AL,turbidity inactive,01.08.2013,07:35<ETX>

For connection to a PC a so-called null modem cable is required.

When you change a setting, brightness or contrast are adapted on the display for previewing purposes. The settings are thus not yet stored.

 Press "OK", to confirm the settings.

Backlighting

There are extensive contrast adjustment options. Values between "3" and "7" are advisable here.

In the event of very warm or cold ambient temperatures, the display may no longer be optimally readable. Correct this by adjusting the brightness and contrast until the display is again readable.

Description of the SD card functions

The SD card can be used to record measurement values and errors as well as for importing and exporting the device settings.

Error and measurement value files are separately placed in subfolders arranged by year and month:

 In the year folder, files including measurement values and errors

are arranged by month. The format of the file names is: ME<Year><Month>.csv for measurement values and AL<Year><Month>.csv for errors/alarms.

 In the year folders, as required, subfolders are placed for the 12

months of the year, within each of which a file for measurement values and errors per day is placed. The format of the filenames is ME<Year><Month><Day>.csv for measurement values and AL<Year><Month><Day>.csv for errors/alarms.

 Data is stored in the "Comma-Separated-Value" format, to facilitate

inclusion in spreadsheet programs and to allow it to be easily imported into databases.

Link between time and correct data

To ensure that the naming of the file and the time and date details in the file are correct, the time function must work properly. If the battery drains, the date is automatically set to 1.1.2011, 12:00 and the data is stored. Data is not lost, since new measurement values and errors are appended to existing files. However, only one file is described in each case, since the month and day are not subject to change.

Storing measurement values

The storing of measurement values on the SD card is activated when in the menu

=> Basic program => Function SD-Card => Store

measurement

is activated.

Example for a CSV file imported into Excel:

Within the file, the comma is included as a separator in the first line "sep=,", so that it can be imported directly into Microsoft Excel. If OpenOffice/LibreOffice Calc are used, this line appears after the import. It may be deleted.

Store error

The storing of the error on the SD card is activated, when in the menu

=> Basic program => Function SD-Card => Store

Interim storage for a non-inserted SD card

Even if no SD card is currently inserted, no measurement values and errors are lost, since the most recently error and measurement values, which have not yet been written into storage, are saved on internal interim storage (ring memory).

As soon as an SD card is inserted, the interim stored data is transmitted during next write operation.

The capacity of this interim buffer is 50 error and 100 measurement values. After this point, the oldest values will be overwritten.

Capacity of the SD card

The storage requirement for 10,000 measurement values amounts to around 1MByte. If error messages occur for one percent of the measurement values, a 2GB SD card for example may have around 19 million measurement values and errors.

Export basic programming data

In the menu => Basic program => Function SD-Card => Export

basic data

all settings of the Testomat device can be stored in a file on the SD card.

This function is recommended for:

- Storing multiple configuration profiles for one device

- Transferring settings onto other devices

- Configuring multiple devices with identical settings

- Remote maintenance / support via transfer of the basic programming data

The filename is preset to "bdata00.ini" (for "Basic Data" / basic programming data). The digits are adjustable, meaning that in total 100 different files from "bdata00.ini" up to "bdata99.ini" can be selected. The files are always stored in the root directory of the SD card.

Editing the file

The settings are in the file in text form and can be displayed or edited, with for example the notepad application on a PC. Use a simple text editor, not a word processor, since otherwise the formatting may be changed!

If files (for example when creating profiles) are later renamed on the PC, please note that the indicator of the Testomat device is limited to 24 characters. Longer filenames cannot be distinguished on the Testomat!

Firmware update

Menu-driven firmware update

In the menu

=> Basic program => Firmware update

the operating software of the Testomat device is updated. For this purpose, you need an SD card.

Implement the firmware update as follows:

 Download the firmware update for the Testomat® EVO TH from the

Heyl website and save it in the root directory of the SD card to be inserted into the Testomat® EVO TH

 Insert the SD card into the Testomat® EVO TH  Select in the menu

=> Basic program => Firmware update

 Confirm the selection with "OK"  Select the filename of the update. If only one file exists, only con-

firmation is required.

 Confirm the selection with "OK"

The Testomat restarts and implements the update. In this mode, although no text is output, the status is indicated via the LEDs of the SD card as well as those on the control card.

During the firmware update, the red LED lights up next to the SD card plug-in slot (which indicates that the so-called bootloader is active).

Page 52

Input basic programming data

The programming progress is indicated as bars with five LEDs on the control card:

Initially, only LED1 flashes (in the vicinity of the plug connector to the motherboard) slowly (once every two seconds) and later permanently, whereupon the next LED begins flashing. The process is repeated until all LEDs light up permanently.

The firmware update is now complete. The Testomat is started automatically with the new operating software. The complete firmware update takes around 70 seconds.

Possible errors:  If both LEDs flash or light up next to the SD card, there is a prob-

lem with the SD card itself. The update could not be started. The

existing firmware remains unchanged.  If the LEDs next to the SD card are inactive, but the LEDs on the

control card flash quickly (10x per second), an error has occurred

during the update.  See Firmware update error messages.

Obtain the settings after the firmware update

After a firmware update, the device may be in an undefined state. After a firmware update, basic programming should therefore always be performed. If the settings have been preserved, it is advisable to export the settings onto the SD card before the firmware update and after the firmware update, to import the saved settings

Passwords

The set password is preserved even after the firmware update.

Error and update log

During the update a file called "update.txt" is written onto the SD card, which includes a record of the update progress and any errors having occurred in the process.

Open these files with your editor of choice (e.g. Notepad), to read the relevant content.

The file is not deleted, but supplemented. If the same SD card is always used for a device, it will provide an overview of all the firmware updates performed for the device in question.

Error messages/troubleshooting

Errors will be recorded in the error history as far as capacity allows (after which the oldest message will be deleted).

In addition, error messages can be stored on the SD card, if in the menu

=> Basic program => Function SD-Card => Store

error

has been activated. Details of errors are always sent via the serial RS32 interface. Errors are handled differently depending on type:

All errors, for which user access is required to recover the function of the device, are shown as alerts. In addition, an alarm may be triggered. However, it is not possible to completely disable the message, since the selection "–" is locked in the menu.

In the event of such error occurring, the device reverts to pause mode. When these errors are acknowledged with the horn button,

they are deleted and the pause mode can be ended. In the event of any recurrence, the set action (message or alarm) is again triggered.

For such errors, the time of occurrence is recorded in a log.

All errors that occur only intermittently, which means they impact only on the analysis process, are cyclically checked by the device and automatically deleted when no longer present.

If these error messages are acknowledged, only the alarm is deactivated. The error message is not, however, deleted. It is deleted only when the error no longer occurs after rechecking (namely, during the following analysis, either automatically or when manually started).

These errors can also be ignored when in the menu Alarm/message "-" is selected.

In the Error history the start and end time are logged. Likewise, two notification messages are written via the serial interface and onto the SD card with the start and end times of the error (see Message for-

mat).

Regardless of the case, the analyses are continued.

Error messages/troubleshooting

Firmware update error list

Has any firmware update error or error occurred after the selftest?

This error can be distinguished using the red LED next to the SD card (see figure on page 51Fehler! Textmarke nicht definiert.Fehler! Textmarke nicht definiert.): If the LED lights up, the bootloader is active and the error concerned occurred during the firmware update. If the LED is inactive, it is an error after the self-test.

 The error category is based on the number of simultaneously flash-

ing LEDs on the control card (for the precise error description,

please refer to the following table):  All five LEDs flash quickly: SD card cannot be read. Replace

card. If the attempted replacement fails, there is a defect on the

control card. Contact customer support; the device must be re-

paired.  Three or four LEDs flash quickly: Defect on the control card.

Contact customer support; the device must be repaired.  Two LEDs flash quickly: The file for the firmware update was

found, but is invalid or defective. Re-download the file.  One LED flashes quickly: Problem with SD card (Write protec-

tion, formatting).

 For the Testomat® EVO TH, the filename should correspond to the

following format: "100M001S00.UPD", where 001 is the version

number, which increases incrementally as new versions are re-

leased.  LED bars not extended: They revert to the original configuration

after some time has elapsed and start from scratch: The means

that during the programming, an error was detected and an at-

tempt was made to resolve the error by repeating the update pro-

cess. The entire programming process is repeated up to five times.

For each repeat, the entire programming process is relaunched

from the start, whereupon the LED bars "emerge".

If, after five attempts, it is still impossible to perform any successful

update, the LEDs show an error corresponding to the list on the

following page. The device or the control card requires repair.

Please also send – particularly in this case – the content of the log

file on the SD card "update.txt" with the item or enclose the SD

card with the device.  Under normal cases, a firmware update is completed within 70

seconds.
