Checklist Testomat
Dear customers and service technicians,
The following checklist is no substitute for your expertise and experience applied to the process of troubleshooting. It should assist you and facilitate
swifter and more systematic detection and logging of errors. No claim of completeness may be inferred from this list. We are grateful to receive
supplementary feedback at any time. General operating instructions are included on the rear of this checklist.
Your device manufacturer
Block 1 / System and device data
Testomat® EVO
TH
System type Device type
Block 2 / error message and error history
What does the error history of the device indicate?
Does an error message appear on the display?
e.g. "Water low" etc. (See instruction manual "Error messages
/ Help dealing with faults")
Block 3 / Visual and functional check
Is the mains voltage for the device in accordance with the type plate?
Does an indicator appear on the display?
Do the three green LEDs light up to indicate the stresses on the mother-
board?
Do LEDs flash on the control card?
Are the measuring chamber and hoses carrying water leakproof?
Is the measuring chamber clean and free of film?
Has the correct indicator type been programmed in?
( TH 2025 => 0.25 up to 2.5 °dH = Factory default )
Is the water pressure in the stipulated range (400 ml/min)?
(See type plate of the device)
Is the outflow over the entire length laid to ensure no back pressure?
(No "siphon effect"!!)
Is the drain hose free?
(Micro-organisms due to contamination etc.)
Is the purge cycle / rinsing water quantity set such that
Fresh water can always be measured?
Are the hoses to the dosing pump free of air bubbles?
(Operate pump by hand / Perform manual analysis)
PERFORM A (MANUAL) ANALYSIS
Does the water level rise uniformly when filling the measuring chamber up to
the overflow hole (5 mm under the top edge of the measuring chamber)?
(If no: check water pressure, water flow/flow regulator)
Does the indicator pump dose when an analysis is triggered?
(LED on the pump comes on!)
After the dosing process, is the indicator correctly mixed with the water in
the measuring chamber?
Check the stirrer! => See maintenance manual "Alignment operation"
PROGRAMMING DATA / OPERATING CONDITIONS
Are the configured limit values correct? (Within the measurement
range/corresponding to the performance limit of the system?)
Is the Testomat continually supplied with mains voltage – except during
maintenance work/emergency cases?
(Intermediate switching off only with "PAUSE" button or "Stop"! input)
More details of error messages and possible causes of errors can be found in the operating instructions under "Error messages / Help dealing
with faults".
Further functional tests (e.g. overflow detection and gain adjustment => "Special function alignment operation") and service indications can be
found in the maintenance manual.
After performing these tests, experience supports the assumption that the checked functions (Block 3) work flawlessly if the questions are answered
with "Yes". We recommend carrying out these tests systematically during each inspection or any disruptions which arise.
