Simulation and test
Procedure
1 Establish contact with SCU 1, using the dunking transducer and the ACU by
selecting the
SCU 1
tab.
2 Test all functions. Start with
DISARM
(if available).
Tap
DISARM
.
3 Press
Execute
, tap and hold
Execute
on the touch screen at the same time until the
command is executed.
4 When the green LED for the valve operation lights up on the simulator (this might
take some minutes), wait for a second or two, then toggle the valve switch.
The switch simulates that the hydraulic pilot pressure has opened the slide valve.
This should result in a correctly confirmed valve operation.
5 When the LED is switched off, check that the correct status message is displayed on
the ACU screen.
FAILURE
is displayed if something is wrong.
6 Continue with the
ARM
function (if available).
Tap
ARM
and repeat steps 3 to 5.
7 Execute all other stack functions from the ACU by tapping the correct function and
repeating steps 3 to 5 for all functions.
8 Establish contact with SCU 2, using the dunking transducer and the ACU by
selecting the
SCU 2
tab.
9
Repeat steps 2 to 7 for all stack functions.
10 Some systems also have a possibility to read analogue sensors. These can also be
tested with the simulator.
The toggle switch will simulate low current, 6 mA or high current, 18 mA readings
on the analogue sensor. One of the valve functions has to be operated in order to
simulate these values.
