[View Manifold]
¤ This facility is the same as view manifold (above) but within the PIN protected area.
[Valve Calibration]
¤ The system operates the apply and release valves, measures performance, calculates
and stores the characteristics of each valve. This takes approximately 20 minutes to
complete.
Note: To complete this set-up requires additional equipment and should only be carried out at
approved equipment service centres.
[Work Valves]
¤ Should a valve be replaced and, before valve calibration, the new valve requires
exercising to bed into the valve seat. The recommended time for this function is 8 hours.
Selecting this function operates each apply and release valves every second until Cancel
Test is selected.
[Cancel Test]
¤ This stops the work valves function.
[Calibrate Sensors]
¤ The calibration function requires the calibration switch on the front panel to be enabled.
This procedure must be carried out by a qualified calibration technician, the details of
calibration are contained in the Druck Calibration Manual for the ADTS 505.
[Auto Leak]
• The ADTS 505 protects the aircraft system against leaks in the aircraft system. The system
protection operates:
¤ Automatically regains control if the leak rate is greater than the parameter rate (RtPt,
ROC) during leak testing.
