2.3 BACK
On the back the connections of the unit are located. Back of watchclock
7
On the connectors which are delivered together with the unit cables with a diameter of 2.5 mm2 can be connected. Note to connection of power supply for BNWAS system: Please note that power supply should be redundant for a BNWAS system to be in compliance with IEC 62616. To do so both a 230 VAC mains converted to 24 VDC, as well as a 24 VDC back up supply are connected. The power supply towards the BNWAS unit will be monitored by two fail safe relay contacts (power supply towards contact means that it is closed) placed in series (please refer to drawing 0897-2113 in drawing section 14). The signal towards input nr. 5 is interrupted when either the mains or the back up supply is interrupted and LED nr 15 (power supply failure) will go on. Once the LED for power supply failure is on, please check which power source is faulty and restore the failure. The back-up power should be provided for at least 6 hours in case of emergency, for which the BNWAS should be connected to a battery as per 7.4.20 of IEC62616.

2.4 HARDWARE PROPERTIES INPUTS
In this chapter the properties of the input channels are discussed. These inputs can be fitted with cable breach and short circuit detection this contributes to an even more secure situation. To use this protection the contact must be fitted with two resistors. A resistor with a value of 1 KOhms in series with the contact and a resistor of 10 KOhms parallel tot this contact. Both resistors should be connected as close to the contact as possible to make full use of the detection. This is drawn in the figure “Detection schematics”. Detection schematics Naturally it is possible to connect contacts without these resistors. In the input configuration the “protection” must be switched off. A contact with or without resistors must be connected between an input and one of the <common in> pins. The resistors used must meet following criteria: Item Property 10 kOhms 5% , metal film 1 kOhms 5%, metal film
Inputs will have the following specifications with or without detection: Item Property Iprotected Current with protection. ca 1 mA Inotprot Current without protection. ca 1.2 mA Rcable Maximum resistance in cables and connections. ca 10 Ohm
The use of a voltage to control an input is not allowed, this can lead to a defective unit
9
2.5 HARDWARE OUTPUT PROPERTIES
All outputs except the 3rd stage and FAIL outputs are of the open collector type. The emitters of these open collector outputs are tied together in the “output commons”. The outputs have the following specification: Item Property Vmax 48 VDC Imax 1000 mADC RtypE Resistance at an “Energized” output < 50 Ohm RltypNE Resistance at a “Not Energized” output. > 4.5 MOhm
The use of alternating current is not allowed. For the 3rd stage and FAIL outputs the following specifications apply: Item Property Vmax 48 VDC/AC
Imax 1 ADC/AC The 3rd stage and FAIL outputs are potential free.
2.6 TIME SELECTIONTIME SELECTION
To use external time selection use the inputs “Input Use Time select”,” Input Time select 1” and “Input Time select 0”. To use the possibilities 3, 6, 9 and 12 minutes with <Input Time select 0> and < Input Time select 1> it is necessary to make the input <input use time select> active, with the default configuration. This means it has to be connected to one of the <common in> inputs. For the correct connections for <Input Time select 0> and < Input Time select 1> see the relevant chapter about inputs.
2.7 CONVERSION FROM 596
This unit is the successor of the 596 watchclock. The 596 didn’t comply anymore with modern rules therefore the BNWAS is developed. For easy installing we have included a table with a cross reference how to connect the new unit. Pin 596 Pin BNWAS 1 (+24 V) 50 (18-32 Volt) 2 (+24 V) 50 (18-32 Volt) 3 (0 V) 48 ( 0 Volt) 4 (0 V) 48 ( 0 Volt) 5 (Alarm NO) 44 (3rd stage NNE (NO)) 6 (Alarm Common) 42 (3rd stage common) 7 (Alarm NC) - 8 (Reset) 21 (Common in) 9 (Reset) 15 (Input reset) 10 (Int.

3. OPERATING The BNWAS is operated with a number of push buttons and a key switch on the front. In the following chapters is discussed how to use pushbuttons and the key switch. The key can be removed in any position.
3.1 BNWAS IS OFF
The BNWAS is OFF when the key switch is in the position <off>. None of the timers of the unit is running. When the <emerg call> button is pressed the emergency call procedure is started.
The key switch is in the <off> position. No timer is running.
Even when the unit is OFF the <emerg call> button can be pushed. The emergency procedure will be started.
11
3.2 BNWAS IS ON
The BNWAS is ON when the key switch is in the <on> position. The timer will start running and the 20 % LED will start blinking. When this LED stops blinking, 20% of the time has expired. The 40% LED will start blinking as indication that the time is between 20% and 40%. When the 40% stops blinking, 40% of the time has expired. This process continues until the 100% LED stops blinking. Now the procedure described in the chapter “timing diagram BNWAS” will be started. The timer can be reset at any time by pressing the <reset> button or making the input <reset> active. When the <emerg call> button is pressed the emergency call procedure will be started.
The key switch is in the <off> position. No timer is running.
When the key switch is in the <on> position the timer is started.
After a while some of the time is expired. In this example 40% of the time has already been expired.
12
When the timer has expired, all LED’s will start blinking. This is the “visual indication on the bridge”. When the unit is not reset all other phases will eventually become active.
When the unit is reset by pressing the <reset> button or by making the reset input active, the timer will be reset and started. All alarm outputs will become passive.
At any time the <emerg call> button can be pressed. The emergency call procedure will be started.
13
3.3 BNWAS IN AUTO MODE
The BNWAS can also be put in AUTO mode. The timer will start running when the input <Heading or Track system> becomes active.
The key switch is in the <auto> position. The timer is not running.
When the input <Heading or Track system> becomes active the timer starts running. The LED <on> will turn on. The unit will behave as described in the chapter “timing diagram BNWAS”.
At any time the <emerg call> can be pressed. The emergency call procedure will be started.
14
3.4 TEST
The <test> button is used for testing the unit.
The BNWAS is in normal operation mode.
When the <test> button is pressed, LED’s will go on. The <power> LED will go OFF and the <mode> LED will blink alternating green and red and the buzzer will be turned ON.
When the <test> button is released the BNWAS will return to operational mode.
When the BNWAS is in the operational modes <on> or <auto>, only the front and buzzer will be affected. If the BNWAS is in the <off> mode, all outputs will be active with the exception of the <fail> output.
15
3.5 USING THE BNWAS WITH DETECTION
For maximum security the inputs can be configured with wire break and short circuit detection. In the examples it is assumed that contacts are configured as Normally Closed (NC). The resistors needed for detection are not drawn.
The BNWAS is in operation mode. This is visible because the mode LED is off and de power LED is blinking.
When a short circuit is detected this is indicated by a blinking LED. The light period will be short in proportion to the dark period. The <fail> output will become active and the <3rd stage> output will become active.
When a broken connection is detected, this is indicated by a blinking LED. The light period will be long in proportion to the dark period. The <fail> output will become active and the <3rd stage> output will become active.
Closed contact Short Circuit Wire break The input gives the error and is indicated by the corresponding LED. The first LED is the LED on the top. LED Input LED Input 1 <emergency call> 2 <Heading / Track > 3 <reset> 4 <time select 1> 5 <time select 0> 6 <use time select> 7 not connected 8 not connected 9 <officer selected> 10 <external officer selection>
16
4. OPERATION The BNWAS is in fact a timer. When the timer expires a number of alarms will go off in a well defined procedure. In the figure below the system layout is drawn.
BNWASHeading / Track system Voyage Data Recorder
Master Backup Officer General Alarm
BNWAS System layout The BNWAS can be controlled by a Heading or Track control system, by means of a contact. This contact can be fitted with wire break and short circuit detection. Outputs for a VDR system are provided.
4.1 CONNECTION TO VDR
When the BNWAS is connected to a VDR it is recommended to connect the outputs <VDR Off> and <VDR On> to the VDR. Optionally the output <VDR 3rd stage> could be connected as well.

4.2 TIMING DIAGRAM BNWAS
In the figure below the timing diagram is shown in case the unit is ON or in case the input “Input Heading / Track control system” is active.
BNWAS Timing diagram When the key switch is in the <on> position, the BNWAS will enter the “dormant period”. This period lies between 180 and 720 seconds (3 – 12 minutes). The time can be followed by means of the LED bar. When the timer is expired the LED bar starts blinking, also the “Output Visual Indication” and “VDR Visual Indication” becomes active. If not reset within 15 seconds the internal buzzer will be turned on and the “Output 1st stage Audible Alarm” and “VDR 1st Stage” will become active. Another 15 seconds later, when not reset, the “Output 2nd stage Audible Alarm” and “VDR 2nd Stage” will become active. After a period of 90 to 180 seconds (1.5 – 3 minutes) the “3rd stage” relay and “VDR 3rd stage” will become active.

7.2 IEC 62616
The BNWAS will provide an interface according to IEC 61162-1, ALR sentence, with the following message content: – hhmmss.ss this part may be left blank if the BNWAS does not include UTC time
information – xxx Designation of source of alarm or source of reset command. The automatic mode
is designated as "000". – A (1e) A = Dormant period exceeded
V = Dormant period not exceeded – A (2e) A = Alarm acknowledged
V = Alarm unacknowledged – c - - c: BNWAS mode (see 3.1.1): c1; c2; c3
c1 = AUT or MAN (=ON) or OFF c2 = Dormant period in min, (03 – 12) c3 = Alarm stage: 1, 2 or 3. (hh = Checksum)
Example $BNALR,,000,A,V,C1=AUT;C2=03;C3=1*hh<CR><LF> The alarm message is sent with any change of the BNWAS settings for mode or dormant period, and with any activated and reset alarm. The resulting NMEA strings are in chapter 10.3

9. MAINTENANCE The BNWAS needs no maintenance or calibration. However it is recommended to get the connectors out and in every year, to prevent oxidation of the contacts. The unit may be cleaned with a light wetted towel.
32
10. ERRORS The BNWAS continuously checks its code and configuration when an error is detected. This will be indicated by fast blinking of alternatively the <mode> LED and the <power> LED. The error code will be indicated by binary code with the 10 upper LED’s.
Binary error code
The error can be read in the following table: Error code LED’s ON Meaning 1 1 Error in code 2 2 Error in configuration 5 1 and 3 The dormant time is out of range 6 2 and 3 The 2nd 3rd time is out of range
Error codes 5 and 6 can be accepted with <emerg call>. When this error is generated, this means that the value which is written into the database of the unit falls out of range. For the dormant time this range is 180 to 720 seconds and for 2nd 3rd this is 90 to 180 seconds. If the error code is accepted, the unit will store the smallest available value e.g. 180 seconds for the dormant time and 90 seconds for the 2nd 3rd time. If another error code occurs remove power from the unit, wait 10 seconds and apply power again. If the error remains please contact VAF Instruments or your local agent for further information.

15. WARRANTY CONDITIONS 1. Without prejudice to the restrictions stated hereinafter, the contractor guarantees both the
soundness of the product delivered by him and the quality of the material used and/or delivered for it, insofar as this concerns faults in the product delivered which do not become apparent during inspection or transfer test, which the principal shall demonstrate to have arisen within 12 months from delivery in accordance with subarticle 1A exclusively or predominantly as a direct consequence of unsoundness of the construction used by the contractor or as a consequence of faulty finishing or the use of poor materials.
1A. The product shall be deemed to have been delivered when it is ready for inspection (if inspection at the premises of the contractor has been agreed) and otherwise when it is ready for shipment.
2. Articles 1 and 1a shall equally apply to faults which do not become apparent during inspection or transfer test which are caused exclusively or predominantly by unsound assembly/installation by the contractor. If assembly/installation is carried out by the contractor, the guarantee period intended in article 1 shall last 12 months from the day on which assembly/installation is completed by the contractor, with the understanding that in this case the guarantee period shall end not later than 18 months after delivery in accordance with the terms of subarticle 1A.
3. Defects covered by the guarantee intended under articles 1, 1A and 2 shall be remedied by the contractor by repair or replacement of the faulty component either on or off the premises of the contractor, or by shipment of a replacement component, this remaining at the discretion of the contractor. Subarticle 3A shall equally apply if repair or replacement takes place at the site where the product has been assembled/installed. All costs accruing above the single obligation described in the first sentence, such as are not restricted to shipment costs, travelling and accommodation costs or disassembly or assembly costs insofar as they are not covered by the agreement, shall be paid by the principal.
3A.If repair or replacement takes place at the site where the product has been assembled/installed, the principal shall ensure, at his own expense and risk, that:
a. the employees of the contractor shall be able to commence their work as soon as they have arrived at the erection site and continue to do so during normal working hours, and moreover, if the contractor deems it necessary, outside the normal working hours, with the proviso that the contractor informs the principal of this in good time;
b. suitable accommodation and/or all facilities required in accordance with government regulations, the agreement and common usage, shall be available for the employees of the contractor;
c. the access roads to the erection site shall be suitable for the transport required;
d. the allocated site shall be suitable for storage and assembly;
e. the necessary lockable storage sites for materials, tools and other goods shall be available;
f. the necessary and usual auxiliary workmen, auxiliary machines, auxiliary tools, materials and working materials (including process liquids, oils and greases, cleaning and other minor materials, gas, water, electricity, steam, compressed air, heating, lighting, etc.) and the measurement and testing equipment usual for in the business operations of the principal, shall be available at the correct place and at the disposal of the contractor at the correct time and without charge;
42
g. all necessary safety and precautionary measures shall have been taken and adhered to, and all measures shall have been taken and adhered to necessary to observe the applicable government regulations in the context of assembly/installation;
h. the products shipped shall be available at the correct site at the commencement of and during assembly.
4. Defects not covered by the guarantee are those which occur partially or wholly as a result of:
A. non-observance of the operation and maintenance instructions or other than foreseeable normal usage;
B. normal wear and tear;
C. assembly/installation by third parties, including the principal;
D. the application of any government regulation regarding the nature or quality of the material used;
E. materials or goods used in consultation with the principal;
F. materials or goods provided by the principal to the contractor for processing;
G. materials, goods, working methods and constructions insofar as are applied at the express instruction of the principal, and materials or goods supplied by or on behalf of the principal;
H. components obtained from third parties by the contractor insofar as that party has given no guarantee to the contractor.
5. If the principal fails to fulfil any obligation properly or on time ensuing from the agreement concluded between the principal and the contractor or any agreement connected to it, the contractor shall not be bound by any of these agreements to any guarantee regardless of how it is referred to. If, without previous written approval from the contractor, the principal commences disassembly, repair or other work on the product or allows it to be commenced, then every agreement with regard to guarantee shall be void.
6. Claims regarding defects must be submitted in writing as quickly as possible and not later than 14 days after the discovery of such. All claims against the contractor regarding faults shall be void if this term is exceeded. Claims pertaining to the guarantee must be submitted within one year of the valid complaint on penalty of invalidity.
7. If the contractor replaces components/products under the terms of his guarantee obligations, the replaced components/products shall become the property of the contractor.
8. Unless otherwise agreed, a guarantee on repair or overhaul work carried out by the contractor or other services shall only be given on the correctness of the manner in which the commissioned work is carried out, this for a period of 6 months. This guarantee only covers the single obligation of the contractor to carry out the work concerned once again in the event of unsound work. In this case, subarticle 3A shall apply equally.
9. No guarantee shall be given regarded the inspection conducted, advice given and similar matters.
10.Alleged failure to comply with his guarantee commitments on the part of the contractor shall not absolve the principal from his obligations ensuing from any agreement concluded with the contractor.
11.No guarantee shall be given on products which form a part of, or on work and services on, goods older than 8 years.
