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® to operate reliably, use Heyl
Testomat 2000® indicators. Operate in the pH-range 4 – 10.5,
when determining the total hardness!
With Testomat® instruments for water hardness monitoring, larger
quantities of heavy metal ions in the softened water might
influence the color reaction, especially iron above 0.5 mg/I,
copper above 0.1 mg/I and aluminum above 0.1 mg/l (brownishred color 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 colorimetric 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 any 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
carried out on a regular basis! For more information, please refer
to the section entitled “Maintenance” and the "Maintenance
manual of Testomat 2000®/Testomat ECO®".
If problems occur, please refer to the section entitled "Error
messages/Troubleshooting".

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®.
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 actual
analysis interval cannot be less than 90 seconds.
In PROGRAM, select
=> =>
Enter the " TIMES in seconds (s)
Press "ENTER" to confirm the entry
Setting the internal flushing time
For connections longer than 3 m and with an internal hose
diameter of 6 mm a minimum internal flushing time of 10 seconds
is required 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.
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®.
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®.

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.
With a hysteresis of "2", the next analysis is immediately carried out
when the limit value of this analysis has been exceeded for the first
time. The respective output is only switched after the limit value of
this analysis has been exceeded for a second time. With a hysteresis
of "3", the respective output only switches when the limit value of this
analysis has been exceeded for a third time. This setting is only
reactivated once the value has fallen below the limit value!

Lock out
Analysis monitoring with locking after the first, second or third time a
limit value is exceeded (= hysteresis) is used for error diagnosis. If a
limit value (programmable: LV1 or LV2) is exceeded as often as
programmed (limit value output switched), the instrument remains in
the analysis position and switches to standby (indicator lamp
"STANDBY" illuminates). In the LOCKING position (display
"STANDBY"), the sample remains in the measuring chamber. This
ensures that the analysis result can be visually checked for faults
caused by external effects (e.g. when measuring the water hardness,
excessive iron or copper content results in brown colouration).
Locking is cancelled via the "STANDBY" key.

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 reacts. 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. The switching on time and the interval are
the same.
Switch function 3, two-point
If the upper limit value LV1 has been exceeded, the output relay LV1
switches. If the value falls below the lower limit value LV2, the output
relay LV1 drops out again. The output relay LV2 switches according
to the programmed switch function.
In , select

BOB operation (operation without permanent
supervision)
BOB (operation without permanent supervision) is a safety relevant
feature when using the instrument as a water hardness monitoring
unit for monitoring steam boiler plants in accordance with TRD 604.
If the BOB function has been programmed, the instrument
continuously checks the available amount of indicator. A measuring
value of 0.083 °dH (= 0.015 mmol/l alkaline earth ions) is decisive for
the calculation of indicator consumption per analysis. If the residual
amount is insufficient for the set BOB period (programmable 24 - 120
h), an alarm message is output.
In , select
=> =>
Select "FUNCTION ON"
Enter the time period in hours (h) under "BOB DURATION"
Press "ENTER" to confirm the entry
BOB on: Continuous monitoring of the residual amount of indicator.

indicator only to minimum quantity (filling level 10%)
Example:
BOB time period = 72 hours Number of analyses per hour = 10
Required amount of indicator for 72 h = 72 h x 10 analyses/h x (3 x
30) μl/analysis = 64.8 ml.

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
and hour) and the type of the error.

Description of the relay outputs
All relay outputs are neutral contacts. This ensures that all connection
options are available. The switching of mains voltage and external
voltage, and the direct switching of inputs, e.g. a process controller,
can be realised.
Flushing (external flush valve)
Immediately before each analysis the external flush valve is opened
for the programmed period allowing the line up to Testomat 2000® to
fill with measuring water. Please ensure that the programmed flush
time is sufficient.
Please refer to "Entering further basic program data" "External
flush" for programming details
LV1 and LV2 limit value outputs
Two volt-free relay contacts are available to signal that a limit value
has been exceeded. The limit values, the hysteresis and the switch

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 14 – 16 closed) as long as the fault persists.
- With a message impulse, the output is switched 'on' for 2
seconds and then switched 'off' for 5 seconds.
- If several faults with differently programmed messages are
signalled 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
confirming the fault via the "Horn" key.
- The error message can only be deleted if the fault has been
eliminated.
- Exception: The maintenance has been exceeded. This message
is confirmed in the M menu, see below (Maintenance).
- Each new fault is entered into the error history (also see "i
menu").
- There is no additional alarm via the fault message output when
the limit value is exceeded!
The error messages are described under "Error messages/
Troubleshooting"
Maintenance (output for maintenance message)
The "Maintenance" output is a volt-free change-over contact. During
trouble-free operation without a programmed maintenance interval,
the contact between the terminals 17 – 19 is closed and the one
between terminals 18 – 19 is open.
The instrument is equipped with a range of monitoring functions and
a programmable maintenance interval. The respective maintenance
message is always a continuous contact.
A maintenance request is displayed via the yellow "Maintenance"
LED. The maintenance display can only be deleted once the status
has been corrected or after the maintenance request has been
confirmed.
Please refer to the section "Password protection and basic
programming" for further programming details.
