FOIRE AUX QUESTIONS - FLEX 235 ARRI

Comment changer la vitesse de prise de vue ?

La vitesse se règle via l'interface utilisateur. Les vitesses possibles sont de 1 à 60 images par seconde selon le magazine utilisé. Consultez le manuel pour les combinaisons spécifiques.

Quels magazines sont compatibles avec le FLEX 235 ?

Les magazines compatibles sont les Arrimag 120, 120S, ARRI III 150m et 60m. Les magazines 300m ne doivent pas être utilisés.

Comment effectuer une conversion de 4 à 3 perforations ?

Utilisez le kit de conversion 3 perforations (K2.55018.0). Remplacez le mouvement, le réducteur, les courroies et le film gate. Activez ensuite le mode 3 perforations via le mode service (appuyez 3 fois sur MODE, puis maintenez SET + 3 pressions SEL, puis MODE jusqu'à affichage '3PERF' ou '4PERF', puis maintenez SET + 4 pressions SEL pour basculer).

Comment mettre à jour le logiciel ?

Téléchargez le logiciel de mise à jour depuis le site ARRI. Connectez un câble série entre le PC (port 9 broches) et le connecteur accessoire de la caméra. Allumez la caméra, lancez l'exécutable 235_Uploader.exe et suivez les instructions. N'utilisez jamais de câble CCU (KC-24 ou KC-30) qui pourrait endommager l'ordinateur.

Quelles sont les précautions de sécurité à prendre ?

Travaillez dans un environnement antistatique. Débranchez l'alimentation avant toute intervention. Ne touchez pas les parties mobiles lorsque la caméra est ouverte et en fonctionnement. Portez des lunettes de sécurité. Ne mettez pas les doigts dans le porte-objectif.

Comment nettoyer le caméscope ?

Nettoyez régulièrement les surfaces de contact du film gate et de la plaque d'espacement. Utilisez un chiffon doux et non pelucheux. Évitez les solvants agressifs. Assurez-vous que le jeu du film (0,175 mm ± 0,005 mm) est maintenu.

Quels accessoires sont compatibles avec le FLEX 235 ?

Les accessoires compatibles sont : UMC-1, UMC-3, RCU-1, WRC-1, ESU-1 et IVS-235. Les accessoires RU et CCU ne sont pas compatibles.

Quelle est la plage de température de fonctionnement ?

La température de fonctionnement est de -20 °C à +50 °C. L'humidité doit être comprise entre 5 % et 95 % (sans condensation). L'altitude maximale est de 3000 m.

Comment vérifier la distance focale de bride ?

Utilisez une plaque de mesure FFD (K4.65057.0). La distance doit être de 51,98 -0,01 mm. La mesure et le réglage sont similaires à ceux de l'ARRIFLEX 435. Consultez le manuel de service pour la procédure complète.

Que faire en cas de surtension ?

L'électronique coupe l'alimentation si la tension dépasse 37 V (±1 V). Vérifiez la source d'alimentation (20-35 V DC nominal). Si le problème persiste, contactez un service agréé ARRI.

Notes regarding the new ARRIFLEX 235 spacer plate

The film gap between film gate and spacer plate is NOT adjustable!

The nominal film gap of 0.175 mm ± 0.005 mm is guaranteed by manufacturing of the spacer plate. 3 faces (A) are raised 0.175 mm in relation to the 5 ribs (B), which form the back side of the film gap.

A spring loaded lever (C) presses the 3 faces on the film plane (D) of the film gate. By this means the dimension and parallelism of the film gap is guaranteed. Of course, the mating surfaces must be always kept clean!

3 Perf Conversion

The ARRIFLEX 235 3 Perf Conversion Kit (K2.55018.0, in preparation) includes:

Notes

1. 3 Perf ground glasses are not included in the 3 Perf Conversion Kit. They have to be ordered separately.

Procedure

1. Open movement and take out the 4 Perf film gate.
2. Before opening the electronic cover turn the mirror shutter out of the lens-port area toward camera left.
3. Open electronic cover (7 screws), take care of connection between electronic cover and body, disconnect electronic cover.
4. Remove long drive belt (A)
5. Remove upper deflection roller (B) and and mount it in thread (C).
6. Untighten screws (D) of roller block.
7. Remove shutter drive belt (E) from movement pulley.
8. Remove 4 Perf reduction gear (F).
9. Remove movement (2 screws (G)) by gently pulling it off from 2 locating pins (H).
10. Install 3 Perf movement
11. Install 3 Perf reduction gear
12. Install shutter drive belt on movement pulley.
13. Install long drive belt.
14. Adjust belt tensions

apply force of 5 N (l) on roller block to tense shutter drive belt.

Tense long drive belt in such a way, that with a test load of 4 N, belt gives way 5-6mm from tangential situation.
- Tense short drive belt (J) in such a way, that with a test load of 4 N, belt gives way 1-1.5 mm from tangential situation.

1. Install 3 Perf film gate.
2. Check flange focal distance and parallelism of film gate to PL-mount.
3. Adjust timing as described in "Adjust timing".
4. Switch electronics to 3 Perf mode:

Activation of the Service Mode

Power-on the camera.

Choose "display mode 4" by pressing the MODE button 3 times.
Keep the SET button pressed and briefly press the SEL button 3 times.
The display changes to Service Mode and the following display appears as long as SET is pressed:

E 25° d 31°

In the 235 Service Mode exist 5 display modes altogether which can be activated in sequence by the MODE button.

In the individual modes, the usual run functions are available. Only differing test data is displayed.

Attention: Emergency switch-off and protective functions may be deactivated occasionally.

Press the MODE button repeatedly until Service display mode 2 will be displayed

Upper line: 3 or 4 perforation

4PERF 0000

To change from 3 to 4 perforation or vice versa keep the SET button pressed down and briefly press the SEL button 4 times. The value toggles between 3 and 4.

Attention: only change this value, if you really want to change the movement type!

Deactivation:

To exit from Service Mode, choose "display mode 4" again, hold the SET button pressed and briefly press SEL button one time or switch-off the camera.

19.Shoot test film.

Adjust timing

1. Untighten 4 screws (C).
2. Position inching knob in position (A). In this position the registration pin penetrates the film at it's maximum.
3. Position the mirror shutter in horizontal position (B).
4. While keeping Position A and B, tighten 4 screws (C).
5. Thread a piece of film and mark frame with a felt pen.
6. Check timing, correct timing if required.
   7.Shoot a test film.

2. Electronically:

Scope

The 235 is a small, inexpensive MOS camera which is designed as a single motor cameras with timing belt drive for shutter and movement

The Main electronics of the ARRIFLEX 235 has the following interfaces and functionalities:

• Interface to the UMC-1 and UMC-3, ESU, RCU in a single mixed layout socket. The socket is designed in a way that the standard cables for the CCU-socket of the older cameras are compatible to it and it has three additional contacts for the ESU and ICU in the mid of the standard 8-pins of the CCU socket. This was done due to space restrictions.
  Two separated R/S sockets
• Optional accessory socket (for interfacing of a capping shutter and other future expansions)
  Control and power stage for the camera motor
  Display and user interface

The electronics is compatible to the following standard accessories

UMC-1 and UMC-3
RCU-1
WRC-1
ESU-1
IVS-235

The following accessories are not compatible and must not be used on the ARRIFLEX 235

RU
- CCU

Safety advice and conventions

The service must be carried out in a static free environment to prevent any damage to the sensitive electronics.

Disconnect the power cable before assembling, disassembling or any other work on the camera.

When it can not be avoided to run an opened camera always take care that no obstacles are in the way of moving parts.

Always wear safety glasses when running an open camera.

Do not handhold any part or touch a part of the camera while it is running.

Do not reach into the lens port.

Signals beginning with a n^* are low active signals.

Always refer to the current schematics and part lists for the latest version of the electronics.
