The FDL 90 - Quadra Page

FDL90

In 1989 the FDL90 was introduced by BTS (the joint company of Bosch and Philips).
The FDL90 was built on the FDL60 frame and used many of the same cards and Control Panelss. The FDL 90 used a new Digital - frame store rack (some cards remained the same as 60) and new CCD scanning sytem.
New Features added from the FDL60:
CCD 181 , improved S/N and no streaking..
Zoom and H&V sizing and positioning
Adjustable H&V TV blanking gen.
5 Recallable Sizing memories
Fixed format size selection
S16 and S35 gates
Option S8 gate
3 perf sprocket option
Pal/NTSC switchable option
10 Bit Store with 4:2:2 / 4:4:4 Digital outputs
10 bit key channel output

In 1993 the FDL Quadra was introduced by BTS. Photo
New Features added from the FDL90:
Finer Hor positioning, Pan Scan.
New colorimetry
Improve resolution
Off raster H&V positioning
Digital 4:4:4 output only option. (no analog outputs)
Improved vert stability, new capstan servo system .
Basic option available (less CPs and monitoring option)
3/4 perf switchable
New FPN store.
New Capstan position
Audio delay unit with digital output
(later Quadra Vision with new optics)

Most (not all) FDL 90s were updated to a Quadra,
less the new capstan position

The update involved installing a number of update kits. Not all FDL 90's received all the kits.
The kits are as follows, with the improvement over the FDL90 noted:

Model Update kit
FD0830 DECOR COLOR New Prism, updated units have a colorimetry label on CCD cover box - Better golds

FD0835 SUPER FPN One FPN card FD0835 (not two 600 # cards) Less - fainter FPN lines

FD0845 SIZING KIT Three FM810 Expan cards - for smother pans (Replaces FD610 cards)

FD0850 RES RINGING KIT Usually Installed with decor, new filter on Corr amp and AD, Less ringing

FD0865 4X4 INTERFACE New 800# cards: Write Ctr FY0817, Address Gen FD0816,
Lum Data out FY0818, Chr data out FY0819- to PAN off raster, true 444 out.

FX0733 KNEE LIMITER Usually installed with decor, new sub card on main amp, Soft white clip

FX0734 BLACK MULTIP Usually installed with decor, new sub card on main amp, Better Neg tracking

FD0885 TACHO KIT - New FY0806 card Sprt Gen & new small black tacho wheel (rear) No Count errors

FD728 for above Capstan New capstan cards FD728 - No Count errors - better vert stab.

FM0630 LC MATRIX IC Usually installed with decor FO-126612-700 new Q109 sub - less color fringe

Each kit could be install separately.

The FD0835 SUPER FPN kit could be installed tow way. One was to have a jumper plug add to the on FPN store slot and the then the new FPN card add. the other way was to change the wiring on the back plane.
With the Jumper plug update the FDL90 was downward compatible with the old cards.

Installing the FD0885 TACHO KIT - New FY0806 card Sprt Gen and FD728 new Capstan control also need a few wires added to the back plane. Because of the new tacho wheel, this kit is not downwards compatible.
With these new cards, a switch on one of the CPU card can be change to put he servo system in to a fast Baltic mode.
Also one of the switches can change the servo mode from 10 (9-11?) to 12 bit.
Most unit were placed at he lower bit setting, the higher setting usually gave a vert. busyness.
Unity vert. Frame is easy to set with the new tacho as the tacho can be move in play and then the lock ring tightened. Also with this new servo system the unit can be switch to 3 pref. without changing the sprocket wheel.

The new FD0865 4X4 INTERFACE needed a few back plane wiring changes. But the unit was still downwards downwards compatible. By removing each of the four cards at a time a feature would be lost.
Write Ctr FY0817 to PAN off raster
Address Gen FD0816 to PAN off raster
Lum Data out FY0818 true 444 out and Black Burst gen lock, a KC type Sync gen would be needed.
Chr data out FY0819 true 444 out.
A new Chroma Delay card as also install in some units. The difference noted is the loss of the 444 - 422 switch.

FD0850 RES RINGING KIT Usually Installed with decor, new low pass filter on Corr amps and ADs gave the unit, less ringing. A switch on one of the CPU card needed to be change to tell the FDL90 that this mod was installed.
The FDL90 would then use different clk frequencies to give the FDL90 less ringing and a little more resolution

FM0630 LC MATRIX IC Usually installed with decor FO-126612-700 new Q109 sub - less color fringe
This part, as of this writing, can still be ordered and installed in any FDL60-FDL90 to replace the Q109 glass pack on the Lum-Chr mux card.

Very early FDL90's needed a back plane wire add to support the S16mm gate.

CCD Scanning

The Clock rate and Hor. line frequency to the CCD of a FDL 60 was changed only when changing modes (16 mm, 35 mm, Letter Box.) In the FDL 90 and Quadra the Clock rate and line frequency to the CCD and the front end video system changes with zoom and sizing. A very unique system is used: varying the Clock rate and line frequency is part of the sizing of the video. With Clock rate and line frequency changes, the video level also changes. The CCD gain card in the video rack keeps the CCD output RGB video level at 100%. The Expan card in the Digital rack are used to change the hor sizing and postioning. This changing Hor Line rate is one reason the FDL and Quadra Telecones needs a special WFM.

Audio

Almost all FDL90s can with the optical audio pick up system. the Optical audio system became a option with the Quadra. The Quadra optical audio system required a external audio digital delay unit. This was to correct for the new capstan position. The new capstan position, put the capstan a little closer tot he sprocket wheel and improved the vert. stability a little. This improved the handling of film with shrinkage.
The audio delay unit could be the unit made for the Quadra or any third party unit.
The audio delay unit made for the Quadra would automatically adjust for 16 mm, 35 mm and SAS (Var speed).
This unit had an AD and a AES delay unit. The back to analog out card was optional. This was part of BTS's 400 ser. rack mount equipment.

Tips

FDL 90/ Quadra Parts
Many FDL 90/ Quadra Parts, you can still buy, can be used in a FDL 60. Most analog video cards (less cor amp), all the audio cards (including the Stereo dolby amp) and some control cards will work in a FDL60. DL FDL90 parts (right click save link as) list. Parts like 24V Lamp PS, Direct Drive Spool Amps, Capstan Amps, Direct drive spool motors, Auto white black, Control amp, Pro IF, Z801 CPU, Genlocks, encoders, Power Fuse distribution box, Stereo PU, control panels, optical blocks with some mods all will work in a FDL 60.

Hot Plug Cards?
Many FDL90-Quadra cards can be removed and plugged in hot.
Cards that cannot are the CPU bus cards and the Digital rack cards.
Like Film timer, CPU, Proc IF, Capstan Ctl, Sprocket pulse, Clk Gen.
The Video Genlock Card should not be pulled or plugged while the unit is in stand by mode.
CCD 181 pre amps cables and PS can not be plugged and unplugged hot.
No PS should be turn on off hot (if one is off it most likely will not hurt anything.)

Capstan

Capstan will not run? Or the Servo not locking well?
Capstan lamps is most likely not good.(out or dim)
Do not sub, use a OSRAM 6251 6v 5w

24V Lamp PS
With the 24V lamp PS it is not uncommon for the Bridge Diodes to short and blow the fuse in the front. PW10, or MPI 4010 shorts. Replace with NTE-ECG5324 400v 25a or ECG5326 600v 25A or NTE5322 200V40A or NTE5340 200V 40 Amps or NTE5342 600V 40 A. This Bridge outputs 48 Volts.

24V Lamp PS

24V lamp problems , could be the modlex looking type connector pins on the lamp house. If the Lamp PS cable goes bad, by pass the bad pins with the wires and lugs or solder and tubing till parts come to repair.

The Same type of connectors can go bad on the DC power input to the Digital rack.

Sepmag problems?
Servo Problems in step or slow speeds? CPU locked up?

The +5 volts on the Film Timer should be +5v -.0/+.1 volts. Set with pot "+5V" on card.

If this +5v is noisy (more than +/- .3v on a scope) replace the 1,000uf 6v (or higher) and the 3,300uf 16v (or higher) c

Power Up Test
CPU - Proc IF card LEDs. Power up test
1) CPU Ram bad
2) Eprom check sum bad (bad eprom)
3) PPI port bad (or support IC around it).

PPI ports are on the Proc IF, Capstan ctl and CPU cards.
(Capstan PPI and support ics can go bad with hot plug and power hits)

Cooling
A cool FDL will run longer and last longer, keep it 72 deg. or less.

Cooling

Clean filters located under the power and frame store rack.
These are remove from the front after removing 2 screws holding the
cover strip. Filters can be cleaned with soap and water. Replace if
needed. Failure to clean will cause FDL to over heat.
Also remove the x power supplies and clean the air holes.
If filled with dust the FDL will over heat even in a cool room ! Check the FDL Fans often

Fuse Holder

If a 30 amp fuse holder burns up, just bypass it, to get up and running, the breaker feeding the FDL will still protect the unit from shorts and alike, till the holder is replaced.. or
Replace with a round 30 amp circuit breaker that will fit into the 30 amp fuse holder place.
Grainger has round 30 amp breakers that will work in place of 30 amp fuses

Power Input Terminals

Like wise if the input terminals burn up, use the spare ones, label F (for fire heat switch, remove the F wires not used)
or just run the wires into the Power fuse box and connect to the wire inside, by passing the input power strip. Check out wiring the FDL's power.

24V Lamp

Installing a small fan to cool the 24V lamp will make it and the lamp socket last longer.

Lamp Socket For 24V Lamp P/N F3-116900-014
OR
F0-000991-016 For two Lamp Scockets with the connector

Utility AC Outlet

There is a spare 115v outlet on the front and rear of most FDLs, but it is a Germany AC plug.
You can get an adapter for this at many electronic stores or at the travel section of many department stores.

Spool Servo Brakes

Spool brakes dead?

Check all the RS-12 and RS-6 replays in the spool amp.

Contacts will open. Replace with original or sub.

RS-12 is 12v DC relay , RS-6 is a 6V DC relay.

Use a large Iron to remove relays with out damaging the traces. Check for trace damage after removal and after installing the new relay.

Test brakes, push up one tension arm, both brakes should release (reels spin freely). Hold both arms up push stand by, reels should spin. Hit play (have three hands?). drop both arms. Both brakes should be on (reels do not spin freely).

Test Monitoring
The Store TP on the scope selector shows you the Store A/D, D/A the Lum/Chr Mux and the Contours card.
What to see just the Lum/Chr Mux card's output? Look at the BNC cables leaving the Video rack going to the Digital Racks A/D (lum, r-y & b-y).

What to see the store D/A outputs before the Contour Cor cards (If you have anolog out)?
Again look at the BNC cables (lum, r-y & b-y) going from the D/A to the Video rack.
Just loop or tee the video up to the B input of the Tek scope. For the Lum/Chr Mux cables set the TP selector to the Main Amp for the correct sync input. For D/A set it to Store.
[The Video before the store is not NTSC.]

Film Deck Control

Film Deck remote control switch bad?
Replace with an off the shelf, two position 4 gang switch and just do not use the Rem 2 position,
that is not used much any ways.

Film Deck CP not working, (FDL powers up ok and FPN is ok, but the CP is dark)
Try unplugging it hot (on the digital rack plane panel) and then plug it in Hot.
If that makes it work install a CPU reset switch to the Film Deck CP.

Neg. Film Settings
In a Neg. film transfer mode there are too things that remove the orange mask of the Neg. Film.
First is the Blue / Cyan optical filter that should move into place when Neg. is turned on.
If not, the switch for B&W neg. may be off on the Control IF card.
Next, there are Gain and Black setting that turn on in the Cor amps.
These Gain and Black settings can be fixed Resistors or pots that were added later.
Playing a known good Neg. film with whites and Blacks in it, set the Black CP knob so the highest channel is set to 90 IRE on the Scope at the TP selection pre amp. Now, the Scope TP selection at Cor amp should have all three channel to about 100IRE and 0 IRE of signal level.
If a channel is very low or high, these Cor Amp presets may need to be changes.
R170 for Blacks, R122 for Gain on Cor Amp FD221.

IP film is transferred as Negative film, but the video level is is not inverted on the Main Amp.

Have old Positive Films that are faded?
Transfer it as a IP film.
Use the Neg. matching pots to do the coarse color corrections, looking at the Main amp scope TP selection. Switch the FD120 B&W switch to see which setting gives you a better color balance setting.

Have B&W Neg. Film?

Transfer it as a Neg. film.
Turn off the blue filter with the switch on the Control IF card in the Digital rack.
Use the Neg. matching pots to do the coarse color corrections, looking at the Main amp scope TP selection.
Don't have a blue filter switch on your Control IF card, install one. Put a switch on the Front panel. Install it in series with the line that drive the blue filter solenoid. Pin a30 on the FD120 card.

Need more out of your Contour Card?
Try turning the Hor Detail Width and Detail Notch pots on the Contour Card.
The Noise Comp pot on the front panel should be just a little of the end stop, about 2.
Don't play with the delay line pots!

Power Supplies
Bad PS?
Lamp 24V, 115V, 8.5V or 15.5V or 18.5V
Need it up and running fast?
Use an external power supply to get you up and running fast.

24V Lamp PS runs at 23.3V at 11 amps (250W)
8.5 V PS run at 8.5 V at about 12 amps (100W)
15.5 V PS run at 15.5 V at about 7 amps (100W)

Use the FDLs Switched AC to power the ext. PS. (Lamp PS optional)

Don't have a 24V 250W PS?
Use the bad Lamp PS to power the 24V lamp and the spare lamp.
Wire the two lamps in series and put them across the un regulated 48 DC found in the 24V Lamp PS.

Be careful! Be safe!

No Chroma? No video?
Bad Q109 on your Lum/Chr Mux?
Q109 pn F3-114805-109
Sub newer KM 630 p.n. F0-126612-700

TCL locking problems?

Check the 240 HZ IR pulse on the front of the Proc IF card.
The 555 timer IC makes the IR generator on the Proc IF cards.
Set with resistor on stand off lug by the 555 IC.
Check and set with good frequency counter.

No video?
Turn on the FDL 60's Color Bar Gen.
If bad, only the Encoder and Genlock card are used to make CB.
Check for bad pots and bad sync (Z134) IC.
Check the FDL's CB output, not the color correctors CB, Dav Bars.
No FDL CB? The Ua723 IC on the encoder maybe bad or the diode on the CB switch in the CP maybe bad.

Reel Hold downs pop off?
Pull back the rubber pad to find two screws. Remove the two screws
Use a C clip wrench to remove the clip. Remove the three screws.
Pull down the ring washer, so the two hold down pins come out.
Clean the shaft, pins and washer with alcohol.
Manually pull the spring to make it longer and strong.
Lightly grease or oil shaft and re assemble.
Use just a little contact cement to hold the rubber pads on,
if you completely removed them.
