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 2000® Fe requires an interference free and stable power

supply. If necessary, use a mains filter to protect Testomat 2000®
Fe against interference voltages caused, e.g., by solenoid valves
or large motors. Never lay connecting cables parallel to power ca­bles.

Operation

 Ensure that the maximum electrical load capacity of the relay out-

puts is never exceeded.

 Immediately switch off Testomat 2000® Fe and contact service

staff if malfunctioning occurs. The warranty will be void if you tam­per with or attempt to repair Testomat 2000® Fe. Repairs must be
carried out by authorised service staff.

After switch-off and longer downtime

 Ventilate the indicator leads as described in the start-up, because

longer downtimes (more than 6 hours) can cause the indicator in
the leads to retract.

 Do not switch off the appliance for longer periods (e.g. over the

weekend) via the start/stop output. The indicator can retract from
the leads. This results in measurement errors after the appliance is
switched on.

Cleaning

 Only use a dry, lint-free cloth for cleaning.

De-installation

 Prior to de-installing a defective instrument, always write down a

description of the error (failure effect). It is only possible to repair a
defective instrument (irrespective of the warranty period) if it has
been de-installed and returned to us with a description of the error.

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 outlet valve of
Testomat 2000® Fe.

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 the menu, select

 Press "ENTER" to confirm the entry

Setting the internal 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 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® Fe.
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® Fe.

Limit value monitoring

It is possible to program the limit values on a continuous scale. The
limit value range depends on 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.

A further analysis is carried out immediately after the limit value has
been exceeded for a hysteresis of "2". 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!

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. The switching on times and the intervals
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.

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
reagent level has not been programmed as an ALARM/MESSAGE, it
is not registered in the error history. Up to 20 error messages are
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.

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 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-

inated.

- Exception: The maintenance date has been exceeded. This

message is confirmed in the M menu, see below (Maintenance).

- Each new fault is entered in the error history (also see "i menu").

- There is no additional alarm via the fault message output when

the limit value is exceeded!

Refer to "Error messages / Troubleshooting" for a description of the
error messages.

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 entitled "Password protection and basic
program" for further programming details.

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 always due to
an error which, in certain circumstances, may also cause damage to
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. Please also inform us of
the measured medium. Before you return the instrument for repair
work, remove the reagent bottles and ensure that the measuring
chamber has been flushed out and is empty.
