Op!on Descrip!on
1. History This op on allows the user to browse recorded statuses (threshold exceeding, faults) that
occurred at individual detectors. Status memory can be cleared.
2. Detector info It displays detailed detector informa on, including:
•
Range, alarm threshold values.
• Detector type and type name.
• Measured substance CAS No. and name.
• Detector’s me of opera on in days, date of last calibra on.
• Detector network address, its serial number.
• Informa on on detector diagnos c status (cri cal and non-cri cal fault records). When
fault codes are different than zero the icon
appears. Push bo+om under the icon allows
to read informa on about fault type.
3.Concentra on
graph
Presents the gas concentra on graph recorded by individual detectors over the last 90
minutes of system opera on.
4. Cancel lock It allows users to cancel detector lock. This opera on is possible when the detector is in lock
mode.
Prior to using this op on, find out the requirements to be met and the
procedure for lock cancella on.
5. Zero detector It makes it possible to zero the detector. A er choosing this op on, the Control Unit sends
a zero command to the detector.
Prior to using this op on, find out the requirements to be met and the
procedure for detector zeroing.
6. Noise gateway It makes it possible to set a detector noise gateway threshold parameter. Possible seNngs
range from 0 to 5%.
7. Alarm thresholds It makes it possible to set detector threshold levels. The user is requested to enter 6 values
– 3 alarm thresholds “upwards” and 3 “downwards”.
These possible seNngs include:
•
not less than 10% of the range
4
• not more than 95% of the range
• for detectors opera ng with % LEL unit not more than 60% LEL
• it is possible to disable lower limits.
8.„Inhibit” mode It is possible to exclude the detector. A er ac va ng this func on, the detector is
disconnected from the system.
The “Inhibit” mode does not mean that the detector is without power supply.
It is not allowed to open it without prior power supply disconnec on
9. Set loca on This op on allows users to set a detector loca on. It is possible to enter a text of 8 characters
from the range a-z, A-Z, 0-9, hyphen and space.
10. Log off The system returns to basic access level (level 0) – see sec on 5.3.
Table 12: Detector menu
4 Threshold seNngs are introduced in a physical unit, while limits are values entered in % of the range. Numeral values can vary.
