OPERATION INSTRUCTIONS

BOARD LAYOUT

The board is designed to control jet wash, vac/fragrance machines etc. 12 on board relays to control off board motors, pumps, valves, compressors, lights etc. Six coin or token inputs can be accepted. In 'buy time' mode the board adds up the value of coins inserted and allows the user to select from 8 activities during the time period. In token mode ( fixed programmes) the board can be programmed to run 6 programmes each consisting of up to ten steps per programme for pre-set periods of time.Time remaining is displayed on an LCD countdown screen.All 6 counts and the total can be viewed on the LCD also.

1. on board timer accepts inputs from most electronic coin mechanisms and also supplies the 12v power for them.
2. board can be set to ‘buy time’ or ‘fixed programme’ mode.
3. programming is by on board dip switches , on screen remote display and on screen PC or laptop. see pages 2 and 3.
4. time remaining is displayed on a backlit LCD screen.this countdown can also be in cash value remaining if required.
5. an adjustable audible alarm can be set to warn of the end of time periods. also screen flashes during this period.
6. startup can be automatic when a coin or token is inserted or by an additional ‘start signal’ input.
7. a count of all inputs and their total can be viewed at any time in numerical or the cash value. values can be zero’d.
8. a speed control allows ‘speed up’ or ‘slow down’ of normal run time..
9. for cold climates the board has a remote temperature sensor to control a ‘blowdown programme ‘ for emptying water pipes. the temperature at which this occurs can be selected between 1 to 6 degrees C. also blowdown can be set to repeat at regular intervals.
10. board power is in 2 sections. this allows ‘shut down’ for customers but blowdown can still operate.
11. a pad wash input allows the owner to wash down the forecourt independently of the coin mechanism.
12. the 12 relays are in 2 sets of 2 and 2 sets of 4. this allows for up to 4 different output power values. ie 12v , 24v , 110v , 230v etc.
13. there is an engineer’s test programme , number 7 , for problem solving.
14. all outputs are fuse protected and led signalled.

SET UP PROCEDURE

1. Connect 12V AC to the board power terminal and connect up to 4 different power values for relay outputs.
2. Connect the coin mech. The 10 pin connection provides 6 coin signals & supplies 12v power to the mech.
3. Connect remote , LCD , Count Down Display board.
4. Connect 12v DCAlarm. Set alarm time on 4 pin alarm dip switch no 2.
5. Connect up to 8 ( instantaneous ‘I’) activity selection switches if used on a ‘Buy Time ‘ machine..
6. Connect up to 6 x 12v DC mechanical counters if required. not polarity sensitive. there is an electronic count.
7. Connect relay outputs to solenoids , motors , etc.Relays 1 & 2 ,10 amp others 5 amp. Calculate and fit ‘appropriate’ relay fuses. board comes with 1 amp fuses fitted.
8. Connect FUNCTIONS input terminals to (I) instantaneous or (C) constant switches.

- INPUT 1‘C’... Padwash. Runs the padwash activity while switched on
- INPUT 2 ‘I’… Engineers test programme 7 will operate after signal input.
- INPUT 3 ‘I’….Remote count switch. Repeats the onboard Switch 1 to scroll thro’ 6 counts and total on LCD.
- INPUT 4 ‘……used for bagshake on vacuums or similar system.
- INPUT 5 ‘I’ …Remote Start. if remote start has been selected a signal is required here to start countdown.
- INPUT 6 ‘C’…Speed control signal.During input here speed change operates.
- INPUT 7 ‘C’ Not in use , control …cuts power to coin mech &LCD but leaves blowdown power.

Auto Blowdown function.

Connect the temperature sensor and select temp value if blowdown function ( programme 8 ) is required.When temp drops below selected temp value blowdown programme will operate immediately. It can also be set to repeat at selected time intervals. dip switches 4 and 5.

PROGRAMMING

We use 3 types of programming , on screen PC , on screen LCD and on board dip switches.

a. On Screen PC

Activities for buy time and fixed carwash programmes are set via a PC or Laptop using the Smart programming software and downloaded via the RS232 on board input socket.

Open the programme and set up to 8 ‘activities’ by selecting which of the 12 relays will operate per activity.
Then set up to 8 fixed programmes of up to 10 steps using the 8 activities and set the time period for each step (activity) to run. Timing can be from 6 to 4095 seconds (one hour , 8 minutes and 25 seconds ) per step !

Programme 7 MUST be the engineers test programme and programme 8 MUST be ‘Blowdown’ or ‘Bagshake’. ( remove R31 jumper for vac machines if bagshake is required ).
The programming memory is contained on board in a small 8 pin , easily removeable chip , labelled U13. This allows chips to be programmed at head office and fitted by engineers in 5 minutes on site.

b. On Screen LCD

On board programming uses push button switches sw.1 and sw.2 and is viewed on the LCD.

Before starting determine the following,
1. how much time is to be allowed per 5 pence eg 9 seconds relates to 3 minutes per pound.
2. do you want an auto delay time from coin input to machine start.
3. do you want the electronic count to be in numbers of coins or coin value.
4. do you need to speed up or slow down the normal rate ? if so calculate the value to be set from 2.55 to 0.01. 1.00 is normal time 0.50 is twice normal and 2.00 is half normal speed etc.

Now switch on board power and press sw1 and sw2 during the screen count from 111111 to 999999..The screen will now show 001-C1. for UK coinage now press sw1 6 times until 000-dE shows. Now set any auto delay time you want in seconds by pressing sw2. Then press sw1 to display –Co or –do , select –Co to show the coin count by number of inputs or –do to show the cash value of coins taken.Press sw1 to show 0.25-Ct. this is the speed control setting , select required value then press sw1 to show a security code.Do not change this value and press sw1. screen shows END and reverts to countdown mode.

c. On Board Dip Switches

ther functions and values are set via 5 on board dip switches.
Dip switch 1. 8 pin.Set ‘base time ‘ to be associated to base cash value. see programming page 3.pin 1/1 sec , pin 2/2sec etc., 3/ 4 , 4/8 ,5/16 ,6/32 ,7/64 , 8/128 secs.
Dip switch 2.4 pin Set alarm time. pin 1/10 secs , 2/20secs , 3/40 , 4/80 secs.( Display flashes also )
Dip switch 3. 8 pin. 1,2, not used , 3. display Coin or Prog. Number selected or not , 4. select ‘buy time’ or fixed programmes ,5. non stacking or stacking of inputs , 6. show minutes and seconds or seconds only countdown ,
7. auto start or remote start , 8. show ‘time’ or ‘cash value’ remaining countdown. OFF and ON respectively.
Dip switch 4 set the repeat delay time for blowdown. pin one 10 mins 2/10 3/20 and 4/80 mins
Dip switch 5 set the temperature value for blowdown to operate. pin 1 is 1 degree etc. select only one pin. if none are set blowdown will not operate.
