AVI-1674/EIU-782/T
Relay Closure simulation shall conform to the requirements of: [AD06] Table 3.5-28 (Relay Status
Acquisition Source Specification)
AVI-1679/CREATED/T
In open-loop test mode Relay state shall be commanded by local MMI or by the CCS (Test Procedure
or Command Line).
AVI-1680/CREATED/T
In closed loop test mode, the RTS shall command the Relay state required.
3.6.15 Analog Voltage Simulation
The EIU provides a facility for measuring input voltages.
AVI-1683/EIU-804,EIU-809/T
The Avionics SCOE shall provide simulation of 16 type AN1, 48 type AN2 and 20 type AN3 Voltage
outputs towards the EIU.
Note
1
: The AN2 allocation includes those already specified for FSS Simulation/Stimulation (Sections
AVI-4141 and AVI-4144).
Note
2
: The AN3 allocation are those already specified for CPS/MPS Pressure Transducer Simulation
(Sections AVI-401 and AVI-583).
AVI-1684/CREATED/T
AN1 Voltage simulation shall conform to the requirements of: [AD06] Table 3.5-8 (Analog Driver
Specification 1)
AVI-1688/EIU-805,EIU-801/T
AN2 Voltage simulation shall conform to the requirements of: [AD06] Table 3.5-10 (Analog Driver
Specification 2)
AVI-4230/CREATED/T
AN3 Voltage simulation shall conform to the requirements of: [AD06] Table 3.5-12 (Analog Driver
Specification 3)
AVI-4231/CREATED/T
All Voltage simulation outputs shall have a setting resolution of <10mV.
AVI-4232/CREATED/T
All Voltage simulation outputs shall have a setting accuracy of <10mV.
AVI-1685/CREATED/T
In open-loop test mode Voltage simulation levels shall be commanded by local MMI or by the CCS
(Test Procedure or Command Line).
AVI-1686/CREATED/T
In closed loop test mode, the RTS shall command the Voltage simulation levels.
As a means to reduce channel overhead on the Analog Simulation instruments, the subcontractor may
consider supplying a single Analog Interface type (i.e., AN3) providing the requirements of AVI-4231 and
AVI-4232 are met.
