We propose that the check-out and troubleshooting of
PCB's be performed on Zehntel "In Circuit" testers.
Testers of this type are being purchased by SHAPE as
test equipment for the CAMPS program and will therefore
be available at NATO's two repair Depots. Personnel
experienced in using the Zehntel "In Circuit" testers
need no special training to perform check-out and troubleshooting
on the PCB's in question. The only requirement will
be documentation on internal connections and component
description of the PCB's. If desired the Depot Maintenance
Course described below can be provided as an option.
This course would be strictly theoretical with no hands-on-training.
The objective of this course is to impart necessary
knowledge to the student of each module to the degree
to be able to create the required test program for
the GENRAD 1795 digital circuit analyzer.
3.3.2.1 O̲b̲j̲e̲c̲t̲i̲v̲e̲s̲
At the completion of this course the students will
be able to:
- explain the functions of any module or major part
- within a module or subassembly explain the function
and purpose of any circuit or component
- within a module or subassembly to explain the signal
flow in all regards to the hardware
- perform all adjustments given the necessary equipment.…86…1

The Instructor's Guide Sheets state the goals of the
lessons. Based on the Training Plan, the Instructor's
Guide Sheet states the expected outcome, the methods
to achieve this, the facilities and aids used, the
way to test the outcome and the time and number of
lessons consumed. Refer to FIGURE 3-2
3.4.4 L̲e̲s̲s̲o̲n̲ ̲P̲l̲a̲n̲
The Lesson Plan is a coherent series of points developed
to state the contents of ech lesson by separating the
lesson into single subjects and defining keypoints
for the instruction. An estimated time for each subject
to be covered is scheduled and the needed references
are noted. Refer to FIGURE 3-3
3.4.5 R̲e̲f̲e̲r̲e̲n̲c̲e̲ ̲M̲a̲t̲e̲r̲i̲a̲l̲
The Reference Material consists of subject related
manuals which are primarily manuals available to the
student when he returns to his site, supplied by handouts,
tests and questionnaires produced for these courses.
3.5 T̲r̲a̲i̲n̲i̲n̲g̲ ̲M̲e̲t̲h̲o̲d̲s̲
The students are given knowledge of the subjects in
lectures, discussions and group work involving informal
talks, with the aid of a blackboard, an overhead projector
and handouts. The students' skills are enabled by
demonstrations hand-on training and studies. Studies
being the students' own examination of a topic. The
students' ability to maintain the system is tried in
tests.

4.1 R̲e̲q̲u̲i̲r̲e̲m̲e̲n̲t̲s̲ ̲A̲n̲a̲l̲y̲s̲i̲s̲
The following constitutes Christian Rovsing's interpretation
of the requirements to spare parts.
1) Bidder shall submit a tentative list of spares
(replaceable subassemblies required during the
first 2 years of operation. The list is Christian
Rovsing's best estimate.
2) Within 60 days of contract award a RSPL will be
submitted. This list will be converted to an ASPL
at a time to be agreed. The RSPL will cover site,
supply depot and repair depot spares.
3) Site and Supply Depot spares shall be delivered
no later than at time of site acceptance.
4) 60 days after the spare parts order has been received
by Christian Rovsing, Christian Rovsing will forward
a specification of which items have already been
codified.
5) Christian Rovsing shall by amendment to the contract
quarantee availability of spares for a period of
15 years from time of site acceptance.

The RSPL will be calculated based on our current predictions
of the failure rates supplemented by our experience
from similar projects. The list is our best estimate
of spares requirement. A separate contract on spare
parts is foreseen. Initial delivery of spare parts
will only comprise items necessary during installation
period, i.e. 1 month usage.…86…1 …02… …02… …02… …02…
4.3 P̲r̲o̲v̲i̲s̲i̲o̲n̲i̲n̲g̲ ̲C̲o̲n̲f̲e̲r̲e̲n̲c̲e̲
Customer and Contractor should hold a conference where
the RSPL should be discussed. The aim is for the customer
to select from the RSPL the spares to be included in
the ASPL. Christian Rovsing will make conference facilities
available for the meeting which will take 2 to 3 days.
4.4 S̲p̲a̲r̲e̲ ̲P̲a̲r̲t̲s̲ ̲D̲e̲l̲i̲v̲e̲r̲y̲
Spares will be packaged in reuseable containers and
shipped to the sites to be available at time of Site
Acceptance Test. Spares for Supply and Repair depots
will be shipped as stated in the contract.
4.5 I̲n̲i̲t̲i̲a̲l̲ ̲S̲p̲a̲r̲e̲ ̲P̲a̲r̲t̲s̲ ̲L̲i̲s̲t̲ ̲(̲N̲o̲t̲ ̲p̲r̲i̲c̲e̲d̲)̲
4.5.1 I̲n̲t̲r̲o̲d̲u̲c̲t̲i̲o̲n̲
The following list represents Christian Rovsing's best
estimate as to the spares needed for the program.
Site spares will support the installed equipment for
90 days with a confidence of 80%.
Supply depot spares will support the sites for a period
of 270 days.
Repair depot spares is an estimate which should be
used for budgetary purpose only. However, the eventual
RSPL will specify the correct quantity.
4.5.2 M̲O̲D̲U̲L̲E̲ ̲S̲P̲A̲R̲E̲S̲'̲ ̲c̲a̲l̲c̲u̲l̲a̲t̲i̲o̲n̲ ̲(̲C̲e̲n̲t̲r̲a̲l̲ ̲E̲q̲u̲i̲p̲m̲e̲n̲t̲)̲.̲
In order to determine the number of module spares it
will be assumed that the failure rate of each module
has an exponential distribution. This approximation
holds true for electronic equipment throughout its
useful life, i.e. wear out phenomenum can be ignored.
To determine the number of spares needed to meet a
predefined confidence level for a given period is therefore
calculated by the poison distribution. The parameters
in the calculation are the total installed parts population,
the length of period for which stock is required, the
confidence level and the Mean Time Between Failures
(MTBF).
At site level the ISPL is based on the matrix for installed
equipment.
At depot level the RSPL calculation is based on the
calculation of spares at sites:
- If no spares are recommended at site level, the
calculation of spares at the depot is based on
the installed population.
- If spares are recommended at site level, the calculation
of spares at the depots is based on the site spare
population.
- If insurance item have been incorporated at the
site level, due considerations have been given
when calculating spares of the depot.
4.5.3 P̲E̲R̲I̲P̲H̲E̲R̲A̲L̲ ̲S̲P̲A̲R̲E̲S̲ ̲C̲A̲L̲C̲U̲L̲A̲T̲I̲O̲N̲.
The peripheral spares consist of a kit containing a
set of replaceable modules. The kits are derived from
the peripheral manufacturer's RSPL and has been performed
in accordance with good engineering practice.
4.5.4 I̲N̲S̲U̲R̲A̲N̲C̲E̲ ̲T̲Y̲P̲E̲ ̲I̲T̲E̲M̲S̲
Insurance type items are items, which are not required
for statistical reasons, but should be included for
operational reasons.
The items which have been given insurance consideration
are identified in the 'NOTES' column of the ISPL.

The estimate for repair parts needed is Christian Rovsing's
best estimate. The quantity and types of parts eventually
to be stocked depends on the current inventory of the
NATO repair depot. The final selection will be a result
of the provisioning conference.
5̲ ̲ ̲N̲A̲T̲O̲ ̲C̲O̲D̲I̲F̲I̲C̲A̲T̲I̲O̲N̲
5.1 R̲e̲q̲u̲i̲r̲e̲m̲e̲n̲t̲s̲ ̲A̲n̲a̲l̲y̲s̲i̲s̲
1) Christian Rovsing shall furnish drawings or part
numbers or applicable technical data and draft
item identification if required.
2) Christian Rovsing shall provide Spare Parts Design
Change Notices (SPDCN) for the life of the contract.
5.2 S̲u̲p̲p̲l̲y̲ ̲o̲f̲ ̲D̲a̲t̲a̲ ̲t̲o̲ ̲N̲C̲B̲
Christian Rovsing will supply data on items to be codified
consistent with the "Reference Method" which is the
method of identification used by the Danish NCB. As
part of the basic contract Christian Rovsing will codify
a maximum of 400 items.
5.3 A̲d̲d̲i̲t̲i̲o̲n̲a̲l̲ ̲C̲o̲d̲i̲f̲i̲c̲a̲t̲i̲o̲n̲

by contract.
6̲ ̲ ̲T̲E̲S̲T̲ ̲E̲Q̲U̲I̲P̲M̲E̲N̲T̲
6.1 R̲e̲q̲u̲i̲r̲e̲m̲e̲n̲t̲s̲ ̲A̲n̲a̲l̲y̲s̲i̲s̲
1) The RFQ calls for 3 types of test equipment:
- Operator
- Field maintenance
- Depot Maintenance
2) The equipment shall contain BITE which may be hardware
or software oriented or a combination thereof.
3) The BITE shall be capable of identifying 90% of
the possible faults (module level) within 2 minutes.
4) Depot level test equipment (GENRAD 1795) will be
used at the repair depot for failure analysis to
component level.
6.2 F̲i̲e̲l̲d̲ ̲T̲e̲s̲t̲ ̲E̲q̲u̲i̲p̲m̲e̲n̲t̲
The following test equipment will be provided at each
of the 2 sites:
1. Communication Tester TEK 834
2. Oscilloscope TEK 465B
3. Floppy Disc Exercisor SA 809
4. Multimeter FLUKE 8020A
This equipment will be used by the field technicians
for preventive and corrective maintenance.
In addition, software and hardware Built-In Test (BIT)
is provided and available to the technician.
The operator will report any equipment malfunction
to the resident technician.
6.3 D̲e̲p̲o̲t̲ ̲T̲e̲s̲t̲ ̲E̲q̲u̲i̲p̲m̲e̲n̲t̲
Christian Rovsing suggests that the subassemblies delivered
under this program are tested using the ZEHNTEL "In-Circuit-Tester"
available at the two NATO supply depots. Utilization
of a ZEHNTEL "In-Circuit-Tester" will reduce the requirements
for documentation and training a depot level.
It is Christian Rovsing's experience, that to generate
an exhaustive testprogram for a typical Christian Rovsing
module will require an effort of One man month. Likewise,
an adaptor costs approx. 35.000.- Dkr.
However, Christian Rovsing is willing on request to
quote programming effort and cost of adaptors for the
GENRAD tester. This quote would, however, require some
study of the tester.
7̲ ̲ ̲S̲P̲E̲C̲I̲A̲L̲ ̲T̲O̲O̲L̲S̲
Christian Rovsing will, as part of the Maintenance
planning phase, submit a list of Special Tools required
for maintenance at the field level. Special Tools,
needed at the depot, will generally not be required.
However, the final selection of depot test equipment
will confirm this.
The following list of tools is required at each site.
1. Extenderboard for S-Modules CRPOXX
2. V24 Monitor/Loopback adapt CRXXXX
3. XTA Monitor/Loopback adapt CRXXXX

b) A̲s̲s̲e̲m̲b̲l̲y̲ ̲B̲r̲e̲a̲k̲d̲o̲w̲n̲ ̲M̲a̲n̲u̲a̲l̲
The Assembly Breakdown Manual describes and illustrates
the assembly breakdown of the hardware tree in
order to help the staff towards the installation
and maintenance tasks, i.e. in identification of
the replaceable parts and the interconnection between
the modules, units, crates, and racks.
The H/W Assy Breakdown will provide the following
information:
- M̲o̲d̲u̲l̲e̲ ̲L̲e̲v̲e̲l̲
Manufacturer's part number, nomenclature, quantity,
and NATO Stock Number of each equipment, its
major assemblies, sub-assemblies, and modules.
It will include item description, electrical
and mechanical data.
- C̲o̲m̲p̲o̲n̲e̲n̲t̲ ̲L̲e̲v̲e̲l̲
Manufacturer's part number or Christian Rovsing
A/S reference number, nomenclature, quantity,
and NATO Stock Number of all electrical, electronic,
and mechanical components comprising each module
or sub-assembly.
Each module, printed circuit board, and sub-assembly
will show the location of all components adequately
cross-referenced, and using the identifications
used on circuit diagrams provided in other drawings
and lists. Parts summary by nomenclature will be
provided indicating the total quantity of each
part used within the overall equipment.
c) M̲o̲d̲u̲l̲e̲ ̲D̲e̲s̲c̲r̲i̲p̲t̲i̲o̲n̲ ̲M̲a̲n̲u̲a̲l̲s̲

12.1 R̲e̲q̲u̲i̲r̲e̲m̲e̲n̲t̲s̲ ̲A̲n̲a̲l̲y̲s̲i̲s̲
Based on the requirements stated in the RFP and Christian
Rovsing's previous experience with systems in the military
environment the following requirements can be stated:
1) 3 levels of maintenance with associated documentation
- Operator Maintenance
- Field Maintenance
- Depot Maintenance
2) Spares availability at site, supply depot and repair
depot.
3) Repair support during warranty
4) Field Support available from Christian Rovsing
12.2 M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲P̲l̲a̲n̲
During the first months of the program the maintenance
section of Christian Rovsing's System Division will
develop a maintenance plan outlining all maintenance
activities applicable to the program. The plan will
later become the maintenance manual to be delivered
at each installation.
The contents of the Maintenance Plan is shown in FIGURE

12.4.2 C̲o̲r̲r̲e̲c̲t̲i̲v̲e̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲
Corrective maintenance, i.e. fault identification and
module replacement will be carried out by the site
technician. Repair of defective subassemblies will
be undertaken by Christian Rovsing at no cost during
the warranty period. Subsequently, NATO's Repair depot
will undertake the repair.
Implementation of field changes during warranty will
be done by site technicians after instructions from
Christian Rovsing.
Isolation of faulty subassemblies is accomplished by
the use of both on-line and off-line diagnostic software
programs. On-line error detection programs will detect
hardware faults when they occur. This is accomplished
both by background checks and error detection during
data transfer from one subsystem to another. The off-line
diagnostic program provides for a more thorough check
of the various elements of a subsystem. In addition,
this program will be used to verify repaired modules.
12.5 T̲e̲c̲h̲n̲i̲c̲a̲l̲ ̲S̲u̲p̲p̲o̲r̲t̲
Christian Rovsing will, on request, provide technical
support after installation and customers accept of
the system. The support covers both hardware and software
modifications.

The equipment included in the MEDS is designed in accordance
with high reliability requirements of modern EDP-system.
Only first class quality components are used for manufacturing.
To ensure high availability in a system like MEDS,
the equipment is both highly reliable and easy maintainable.
All modules in the MEDS have a MTTR = mean time to
repair, which is less than 30 minutes. This will provide
an availability of 99% or more for the MEDS.
In the following table, all equipment are the associated
MTBF is given as estimates in order to evaluate the
system availability.

The equivalent MTBF (system) is 1̲2̲0̲ ̲h̲o̲u̲r̲s̲ ̲
With a MTTR of 0,5 hour this gives a system availability
as follows.
̲1̲2̲0̲ ̲ ̲ ̲
Avail.(system) =
120 + 0,5 99,58%
========
The calculated availability of 99,6% is higher than
the requested reliability of 99%. These reliability
figures give the availability for a completety operational
system, but the equipment figures show that it is the
peripheral equipment like VDU and printers, which are
most unreliable. Because these items are multiredundent
in the MEDS the availability of a partly but acceptable
working system is much higher.
