11. TEST PROGRAMS
49.
VACUUM TEST
WAITING PERIOD
05:00
- 0.80 bar 01:48
During this phase, a variation of not more than 10% of the maximum low pressure is allowed.
Beyond this, the test will fail.
When the waiting phase is complete, the pressure verification phase begins (LEAKAGE
PERIOD). This will last 10 minutes:
VACUUM TEST
LEAKAGE PERIOD
10:00
- 0.79 bar 06:48
In this phase, a variation of up to ±0.02 bar is allowed, compared to the initial phase value.
Higher variations, however, will cause the test to fail.
The time is counted down until the phase is completed, after which the pressure is brought
back to atmospheric pressure.
VACUUM TEST
LEVELLING
- 0.29 bar 17:19
When the program finishes, the display will read:
VACUUM TEST
TEST PASSED
- 0.01 bar 17:44
The end of the program is signaled with a beep.
IF THE PRESSURE CHANGE EXCEEDS THE PRE-SET LIMIT, THE PROGRAM IS INTERRUPTED
AN D ALARM MESSAGE IS GENERATED.
SEE A COMPLETE DESCRIPTION OF THE ALARMS IN APPENDIX E .
When the door is opened at the end of the program, a report of the test cycle is printed (if the
printer is installed) with all the salient data.
For complete details about printed reports, please refer to the examples shown in Appendix
B, Programs.
