AVL 415SE Smoke Meter — Maintenance Guide
– The Smoke Meter has passed the leak check if the leakage is less than
3.2.1
Leak Check in SERVICE MODE (for Firmware Version 2.10 and Higher)
When this function is started in SERVICE MODE, the leak test is carried out with
the smoke valve open (MV3 or MV4, set of sample 1 or 2 in the "Measurement"
screen when the Two-Channel Measurement Option are installed).
SERVICE MODE is activated by pressing and holding down the paper feed key
when switching on the AVL 415SE. Error monitoring is disabled in SERVICE
MODE. To quit SERVICE MODE switch the device off and on again.
1. Remove the probe from the sampling site and close it off.
2. Activate the leak check.
3. Detect any leaks in the sampling hose and screwed connections if needed.
4. After that switch the device off briefly and then on again to terminate SER-
VICE MODE. That ensures that any error messages that occur are not
ignored.
Information
1. For Smoke Meter systems with "mounted versions" of the option high pres-
sure, and tests via the service mode add
to the above limits (this is not checked by the software automatically).
– If the "FUNCTION TIMEOUT" or the "LEAKAGE EXTREMLY HIGH"
error is displayed on the AVL 4210 (or error 10 or 101 is output at the
terminal), it could not set up the required low pressure within 5 s (i.e.
extreme leak).
– If the "LEAK CHECK NOT SUCCESSFULL" error is displayed on the
AVL 4210, the leakage is greater than the allowed limit (for limits: see
above)
– The actual measured value is displayed (see Fig. 35 on page 42)
For example:
The pressure is not checked during a leak check; no related error mes-
sages are therefore output.
2. Use the AK command AIDA to display the leak factor in TERMINAL MODE.
