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 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.

 All error messages are lost after a power failure.
 Certain instrument faults always trigger an alarm or a message
(see chapter "Description of the relay outputs")!

Function AUX

The AUX relay output can be programmed for the following control
functions:
–
As a function output for the contact with programmable duration
prior to and/or during the analysis, or after an analysis.
For example, it is possible to control the cooling water inlet of an
upstream cooler via a solenoid valve. This ensures that the cooling
water only flows when required, i.e. when an analysis is being carried
out.
