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), erroneous evaluations cannot be excluded (if necessary, use
aerator type R) (See note in the Performance Specifications).
The concentration of influencing contents can be determined by
using our colourimetric TESTOVAL® test kit.
Installation
Always completely disconnect the relevant plant part before in-
stalling the instrument or connecting/disconnecting it to/from the
power supply. Secure the plant against reconnection.
Only connect the instrument to the mains voltage specified on the
rating plate.
Always observe technical data and ambient parameters.
Testomat ECO® requires an interference free and stable power
supply. If necessary, use a mains filter to protect Testomat ECO
®
against interference voltages caused, e.g., by solenoid valves or
large motors. Never lay connecting cables parallel to power cables.

Setting the analysis interval (interval pause)
If the analysis is triggered via a timer, the interval between two analyses is determined by the interval pause (plus flushing time). The
shortest interval pause can be 0 minutes. In this case, analyses are
carried out continuously. The longest interval is 99 minutes.
In the menu, select => BASIC PROGRAM => INTERVAL => TIME
Use the cursor keys to select the interval in minutes
(10 minutes are preset)
Press "ENTER" to complete all the entries
Duration of the analysis interval
The analysis interval is the addition of the "analysis inter-
val", the "flushing time" and the measuring value-dependent
analysis duration (see diagram on the left)
Selecting the quantity control
Minimum interval = 1 litre, maximum interval = 9999 litres. The analysis is carried out once the programmed water quantity has been
measured. The line and the measuring chamber are flushed prior to
the analysis (observe the programmed flush times).

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. It is possible to monitor two limit values. One limit
value output is available for each limit value. The functions of the
allocated relay outputs can be programmed independently of each
other.
The limit value outputs are strictly allocated to the limit values!
1 LV1 = Limit value 1 2 LV2 = Limit value 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.
Entering the limit values
In the menu, select =>BASIC PROGRAM=> LIMIT VALUES
Enter the values for "LV 1" or "LV 2"
Press "ENTER" to confirm the entry
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. 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!
(The basic setting for LV1 and LV2 is 1)

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, 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.
The function 3 is only possible if different values are used for the limit
values LV1 and LV2. For example, for LV1 = 0.2 °dH and for LV2 =
0.1 °dH.

BOB operation (operation without permanent
supervision)
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 BOB period of 72 hours, an alarm message is
output.
Selecting BOB operation
In the menu, select => BASIC PROGRAM => BOB OPERATION
Select "FUNCTION ON"
Press "ENTER" to confirm the entry
BOB on: Continuous monitoring of the residual amount of indicator.
ALARM message "low indicator level" when the amount of indicator
falls below the minimum quantity for the BOB time period: BOB flashes, the ALARM output is switched.
BOB off: No BOB function. Monitoring of the residual amount of
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.
(This corresponds to a filling height of approx. 13 % for a 500 ml bot-
tle)

An active Stop input prevents an analysis start, e.g. via a current
interval. This can be necessary if the plant does not supply water. A
current analysis is stopped when the input valve is opened (while the
measuring chamber is being flushed or filled). The water which has
already entered the measuring chamber remains there. If the measuring chamber is already full, the analysis is executed. Manual start
has priority over the Stop input, i.e. if the Stop input is active, an
analysis can be started manually or a manually started analysis can-
not be stopped by the stop signal. In the operating mode “timecontrolled”, the interval time continues when the Stop input has been
activated.
As long as the Stop signal is present, "STANDBY" is displayed alternatively to the measured value.

Alarm/Message (fault message output)
The instrument is equipped with an ALARM relay output for signalling
faults. The fault message is displayed via the fault LED and on the
display.
Error messages
The error message can only be deleted once the error has been
eliminated!
The "Alarm" output is a volt-free change-over relay contact. During
trouble-free operation the contact between the terminals 16 – 17 is
closed and the one between terminals 15 -16 is open. In case of a
voltage breakdown, the contact between the terminals 15 – 16 is
closed and the one between terminals 16 – 17 is open.
The instrument is equipped with a range of monitoring functions with
the following 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.
- 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-
inated.
- Exception: "Low indicator level", this message is confirmed in the
M menu under Service by entering the new indicator filling level.
- There is no additional alarm via the fault message output when
the limit value is exceeded!
