Pay particular attention to

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

DUO requires an interference free and stable

power supply. If necessary, use a mains filter to protect Testomat
2000

DUO 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

DUO and contact service

staff if malfunctioning occurs. The warranty will be void if you tam-
per with or attempt to repair Testomat 2000

DUO. Repairs must

be carried out by authorised service staff.

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.

Disposal



Dispose of the instrument in accordance with national regulations.
