Functions of the alarm output
The “Alarm" output is an isolated relay changeover contact. During
normal operation, the contact between terminals 10 - 11 is closed
and opened between 10 - 12. In the event of voltage failure, the con-
tact between terminals 10 - 12 is closed and opened between 10 -
11.
The device includes a whole range of monitoring functions with fol-
lowing functions/performance of the "Alarm" output:
- In the event of permanent contact, the output remains "Alarm"
indefinitely activated (terminals 10 - 12 closed), pending resolu-
tion of the error.
The prerequisite here is that, in the menu
=> Basic program => Alarm/Message
the signaling "A" indicating the alarm for this error type is activat-
ed.
- The fault signal at the "Alarm" output is stopped when you
acknowledge the error with the "horn" button or by entering EXT.
ACK. With the help of these inputs and outputs and the transmis-
sion of measurement data (via 20mA current loop or serial RS232
interface), the Testomat can be operated at a master display.
- If the limit value is exceeded, there is no additional Alarm via the
Fault signal output!
A description of the possible causes of error is included in the section
on Error messages/troubleshooting.
Alarm/message – How to proceed when errors
occur
Error messages are adapted to the selected language, but can also
be identified by an error number, regardless of the language used.
All errors are, regardless of the settings made in this menu option:
- stored on SD card if Storing of error messages has been ac-
tivated
- recorded in the error history (the last 20 error messages)
- and sent via the serial RS232 interface.
Detailed information on possible error messages as well as
their cause and remedy is found in Error messages / trouble-
shooting.
Error messages after self-test
For error messages caused by an improperly executed self-test, no
settings can be made; see Error messages after self-test.
