Application instructions

 Wait at least 5 seconds before switching the instrument on and

then off again at the main switch.

 In order for Testomat 2000® DUO to operate reliably, use Heyl

Testomat 2000® indicators in the pH-range 4 – 10.5!

 With Testomat® instruments for water hardness monitoring, larger

quantities of heavy metal ions in the softened water might influ­ence the colour reaction, especially iron above 0.5 mg/I, copper
above 0.1 mg/I and aluminium above 0.1 mg/l (brownish-red colour
display).

 If the measuring water contains more than 20 mg/I CO2 (carbonic

acid), incorrect evaluations cannot be excluded.

 The concentration of influencing contents can be determined by

using our colourimetric TESTOVAL® test kit.

 Careful handling of the instrument increases both its operational

reliability and service life! Therefore, carry out a visual inspection
at regular intervals as described below:

- Has the use-by date of the indicator expired?

- Are the hose connections of the dosing pump free of leaks?

- Is there air inside the dosing hoses?

- Are all the water connections free of leaks?

- Are the doors of the instrument closed properly?

- Is the instrument heavily soiled?

- Are the measuring chamber and the drain duct/drain hose
clean?

 Trouble-free operation is only possible when maintenance is car-

ried out on a regular basis! For more information, please refer to

the section entitled “Maintenance” and the "Maintenance manual

of Testomat 2000® / Testomat 2000 ECO®"

Internal flushing

To ensure that the analysed sample represents the current value, the
sampling line must be sufficiently flushed. If the plant has been out of
operation for a longer period or in case of long analysis intervals, we
recommend you to select a flushing time greater than 60 seconds.
Flushing starts by simultaneously opening the inlet and the outlet
valve of Testomat 2000® DUO.

Duration of the analysis interval

 The analysis interval depends directly on the programmed flushing

time. If, e.g., a flushing time of 90 seconds has been set, the actu-

al analysis interval cannot be less than 90 seconds.

 In , select

 Enter the " in seconds (s)
 Press "ENTER" to confirm the entry

External flushing

If very short analysis intervals are required, or if a very long (several
metres) sampling line or a line with a large diameter is used, an ex­ternal flush valve should be installed upstream of Testomat 2000®
DUO. The external flush valve has to be connected to the "Flush”
outlet. If the unit is used for monitoring two measuring points, external
flushing prevents incorrect measurements caused by sample mixing.
The external flushing time for the valve depends, just as the flushing
time for unit flushing does, on the length and diameter of the supply
line to Testomat 2000® DUO.

Setting the external flushing time

 For connections longer than 3 m and with an internal hose diame-

ter of 6 mm a minimum internal flushing time of 10 seconds is re-

quired to ensure that a valid sample is taken from the sampling

line. The required quantity of flush water for one-minute internal

flushing is 0.5 litres.

Interval pause

If the analysis is triggered via a timer, the interval between two anal­yses (plus flushing time) is determined by the interval pause. The

Limit value monitoring

It is possible to program the limit values on a continuous scale. The
limit value range depends on the used indicator type and the pro­grammed unit. Two limit value outputs are available for monitoring.
This ensures that two limit values or two measuring points can be
monitored. The functions of the allocated relay outputs can be pro­grammed independently of each other.

If the unit is used for monitoring two limit values, the limit value out­puts are permanently allocated to these limit values!

1 LV1 = Limit value 1 2 LV2 = Limit value 2

If the unit is used for monitoring two measuring points, the limit value
outputs are permanently allocated to these measuring points!

1 LV1 = Measuring point 1 2 LV2 = Measuring point 2

If the limit value LV1 has been exceeded, the limit value control dis­play 1 lights up RED and the relay output LV1 reacts as pro­grammed in the switch function. If the limit value has not been ex­ceeded, the display lights up GREEN. The same applies for the limit
value LV2.

Hysteresis

The respective limit value output only switches after the first, second
or third bad analysis (suppression of the first or the second measured
value). This increases the reliability of the analysis evaluation, e.g.
after the measuring point has been switched over or if the sampling
line has not been flushed sufficiently. The hystereses of the two out­puts LV1 and LV2 can be set independently of each other.

Function: A further analysis is carried out immediately after the limit
value has been exceeded for a hysteresis of 2. The respective output
only reacts if the limit value of this analysis is exceeded again. If a
hysteresis of 3 has been set, the respective output only reacts after
the limit value has been exceeded for the third time in succession.
This setting is only reactivated once the value has fallen below the
limit value!

Switch functions of the limit value outputs
LV1 and LV2

Switch function 0, duration

If the limit value LV1 or LV2 has been exceeded, the output relay LV1
or LV2 switches. If the measured value falls below the limit value
LV1 or LV2 without locking, the relevant relay drops out again.

Switch function 1, impulse

If the measured value exceeds the limit value LV1 or LV2, the rele­vant output switches for a settable time (t).

The respective output always remains switched for the set time, irre­spective of how long the limit value has been exceeded. A new im­pulse is only possible once the value has fallen below the limit value!

Switch function 2, interval

If the limit value has been exceeded, the respective output switches
at intervals with the settable time (t) = impulse or interval as long as
the limit value is exceeded.

Alarm / Message

The instrument is equipped with an alarm relay output for signalling
faults. The events which mean a fault at the instrument or are intend­ed to trigger a message, can either trigger an alarm "A" (continuous
contact) or a message "M" (2-second impulse).

The faults are recorded and stored in the error history if the event has
been programmed as an alarm or message. For example, if a low
indicator level has not been programmed as an ALARM/MESSAGE,
it is not registered in the error history. Up to 20 error messages can
be stored. A list of these errors can be opened in the information
menu. The information stored per event is the time (day, month, year

Alarm (fault message output)

The "Alarm" output is a volt-free change-over relay contact. During
trouble-free operation, the contact between the terminals 15 – 16 is
closed and the one between terminals 14 – 16 is open. In case of a
voltage breakdown, the contact between the terminals 14 – 16 is
closed and the one between terminals 15 – 16 is open.

The instrument is equipped with a range of monitoring functions. You
can define the individual statuses as a fault and program the corre­sponding message either as a continuous contact (A) or as a mes­sage impulse (M).

Functions/Behaviour of the "Alarm" output:

- With a continuous contact, the "Alarm" output remains activated

(terminals 15 – 16 closed) as long as the fault persists.

- With a message impulse, the output is switched 'on' for 2 sec-

onds and then switched 'off' for 5 seconds.

- If several faults with differently programmed messages are sig-

nalled simultaneously, the output is switched to continuous con­tact.

- The red LED "Alarm" and the text on the display indicate a fault.

- The fault message signal at the "Alarm" output is deleted by con-

firming the fault via the "Horn" key.

- The error message can only be deleted if the fault has been elim-

Response of a protective circuit

After a protective circuit (fuse) has been tripped, attempt to eliminate
the cause of malfunctioning (e.g. replace a defective valve) before
reactivating the protective circuit. Frequent tripping is usually due to
power overload which, in certain circumstances, may also damage
the instrument.

Malfunctioning/Repairing a defective instrument:
The repair of a defective instrument – irrespective of the warranty
period - is only possible after the instrument has been dismantled and
returned to us with a description of the error. Furthermore, please
inform us of the indicator type being used and the measured medium.
Before you return the instrument for repair work, remove the bottle
and ensure that the measuring chamber has been flushed out and is
empty.
