OPERATIONNOTE
The opening and closing times of the panels vary according to the programming of the vehicle.
The main door control valve, located on the pneumatic control panel on the driver’s left-hand side, enables pressurization of the door system. Whenever the control valve is activated, air pressure is continuously applied to the opening cylinder (small) and the closing cylinder (large) of the door motor to keep the door panels in a closed position.
NOTE
The door control system is only supplied with air once the pressure reaches 65 psi (448 kPa) or 80 psi (552 kPa), depending on the calibration value of the sequence valve. See the vehicle’s pneumatic diagram for more information.
OPENING CYCLEWhenever the door control lever (Figure 1) is in one of
the front door open positions, pressurization of the large cylinder is interrupted. Air pressure is now applied exclusively to the small cylinder piston, which pushes the rack inside the door motor toward the large cylinder.
SECTION 02-202.40FRONT DOOR OPERATOR
The movement of the rack starts a rotating movement of the pinion, which turns the sector shaft. The rotating movement of the sector shaft is transmitted to the door motor rotating cam, and then to the linkage that opens the panels.
To prevent the panels from opening abruptly at the end of their sequence, the door is equipped with a damping cushion. Optionally, the damping system may be installed on the door shaft or integrated into the door motor.
Where a front ramp is installed on the vehicle, a brake interlock mechanism locks the brakes each time the front door is open. The interlock functions automatically, thus the operator has no direct control over this feature. For more information on the brake interlock, see section 08-201: braking system. Depending on the programming of the vehicle, an accelerator interlock system may deactivate the accelerator command whenever the front door is open. Such a system prevents the motor from turning faster than at idle. For more information on the accelerator interlock, see section 09-204: engine and accessories.
CLOSING CYCLEWhenever the door control lever is placed in one of the
front door closed positions, the large cylinder is pressurized (the small cylinder remains pressurized). The net force of the large cylinder, having a larger area, causes the rack to move toward the small cylinder and the movement transfer process is reversed.

MANUAL OPERATION OF PANELSThe panels may be operated manually by releasing pressure
in both door motor cylinders. This can be done by placing the main door control valve, located on the driver’s left-hand side, in the neutral/release position.
An emergency door release valve (optional) covered with a plastic window may also be located close to the front and/or rear door. In case of emergency, for example if the panels are stuck in the closed position and need to be opened, the passengers may break the window using hand pressure and pull the handle to release the doors.

FRONT DOOR VERIFICATIONThe front door verification table has been created
to simplify the verification, the diagnostics and the adjustment of the door system. This table is divided into two parts:
• verification section. This section indicates each sequential step to follow to conduct a complete verification of the front door system. It includes a description of each verification, the reasons for them and a list of the potential problems that could be encountered at the time of verification.
• repair section. This section covers the diagnoses of the problems encountered in the previous section and how to correct them. It proposes, for each case, one or more additional verifications with related comments that help to better understand the situation. Solutions to these problems are also proposed in this section.
INSTRUCTIONSTo conduct a complete verification of the front door
system:
a. Follow the verification sequence proposed in the verification section, taking each objective into consideration.
b. If no problem is encountered during verification, proceed to the next sequence number. If a problem is observed, identify it in the potential problems column in the verification section.
c. Then, refer to the secondary verification associated with this problem on the repair section. Whenever a section proposes more than one secondary verification, proceed in the sequence indicated.
d. According to the results based on the secondary verification, refer to the adjustment column for the appropriate corrective action to be taken. The procedures proposed in this column correspond to those under heading front door adjustments in this section.
To diagnose a problem specifically encountered in service:
a. Identify the problem encountered in service in the potential problems column in the verification section.
b. Then refer to the secondary verification associated with this problem in the repair section. When a section proposes more than one secondary verification, proceed as follows:
c. According to the results based on the secondary verification, refer to the adjustment column for the appropriate corrective action to be taken. The procedures proposed in this column correspond to those under heading front door adjustments in this section.

ADJUSTMENTSADJUSTING THE CONNECTING RODS
NOTE
While tightening or loosening a connecting rod, always use two wrenches, one to hold the rod, and the other for the ball joint stem locknut, thereby avoiding the forcing of the rod and ball joint.
1. Cut off the air supply to the door system.
2. On each rod, unscrew both ball joint stem locknuts. See Figure 2.
3. Disconnect each connecting rod from the door shaft lever. See Figure 2.
4. On each rod, completely tighten each ball joint by holding the ball joint in position and turning the rod.
5. On each rod, loosen each ball joint approximately 3/4 in. (2 cm) while still holding the ball joint in position and turning the rod. Keep a constant tension on each, but do not turn the motor cam of the door. The threads must number the same at both ends. See Figure 2.
CAUTION
Do not apply too much tension, nor permit too much play on the rods. The threaded ends of the rods could be damaged during operation of the door mechanism.
6. Center the limit switches on their mounting plate.Using the limit switch’s adjustment screws, adjust the switches in such a way to respect distances in Figure 3. Retighten the adjustment screws to the torque value specified in Figure 8.

7. Reconnect the rod for the aft panel to the door shaft lever. Tighten the ball joint locknut to the torque value specified in Figure 2.
8. Tighten the connecting rod in order to push the rear of the panel against the exterior rubber seal. Push the panel against the exterior seal until no visible light shows through (less than 20 % luminosity).
9. Turn the rotary cam until a click is heard from the LS1 limit switch or the proximity switch illuminates.
10. Open the door manually and verify that the LS2 limit switch is working; a click will be heard or light will come on.
11. Repeat steps 7 to 10 on the fore panel.
12. Return air pressure to the door system and close the panels.
13. Tighten the connecting rods one complete turn.
14. Verify manually the pressure of each panel by pushing them inwards from outside the vehicle. Both panels should move freely, while displaying a certain amount of resistance, and should react in an identical manner for the same amount of applied pressure. Adjust the rods again, if necessary, continuing to ensure that equal tension is applied to each.
15. Remove air pressure from the door system.
16. Before performing a final tightening of the ball joint stem locknuts, ensure that all the connecting rod ball joints are oriented the same way. Completely tighten each ball joint stem locknut.
17. Tighten the parallel alignment adjustment screw on the upper door shaft arm; the screw must rest against the arm. See Figure 4. Apply medium grade thread locker (blue) on the parallel alignment adjustment screw, if necessary.

12. Recheck the time taken for panel closing and, if necessary, readjust.
13. If the opening speed adjustment has been completed, conduct the adjusting the damping.
ADJUSTING THE DOOR PANEL SPEED
NOTE
Before proceeding, ensure that the telescopic stanchion (optional) is attached on both sides, since it influences the opening and closing times of the panels. Also ensure that the stanchion joints are parallel to the floor.
1. Activate the door and verify the time that it takes for the door panels to open and close using a stopwatch or a Door-o-Meter.
2. Before commencing the adjustment for the closing and the opening, loosen the damping adjustment screw. See Figure 7.
CAUTION
To obtain a precise adjustment, it is necessary to adjust the panel speed in the following order:
1. Speed of panel closing2. Speed of panel opening3. Damping
CAUTION
When making adjustments, never force the adjustment screws in a clockwise direction. The excessive tightening pressure will damage the motor cylinder cap.

DOOR-O-METERINSTALLATION1. Before installing the Door-o-Meter, pressurize the pneumatic
system and close the door. The primary circuit must have a minimum pressure of 120 psi (827 kPa).
2. Viewed from inside the vehicle, the device is installed close to the right-hand door shaft of the fore door panel. It is held in place by a permanent magnet and a flexible, U-shaped clamp. See Figure A2 for the proper installation of the Door-o-Meter.
3. The door’s motion detector operates by way of a potentiometer driven by a flexible rubber wheel. Before attaching the device and beginning the timing of the door opening, adjust the position of the rubber wheel so that the white dot on the shaft is facing the front of the device. See Figure A3.
4. In order to ensure good adhesion between the rubber wheel and the ball-joint (see Figure A4), completely screw in the magnet behind the housing.
NOTE
The magnet is attached to a sliding door. If it is necessary to open the device’s housing, it is important to replace the door correctly, in such a way that the magnet is in its proper place.
5. Any slippage between the rubber wheel and the ball joint will create an erroneous reading for the timing of the door movement. To avoid any slippage, ensure that the rubber wheel, as well as the ball joint are clean. It is advisable to clean both before starting the test procedures with some rubbing alcohol.
6. Install the magnet so that it is mounted on a metallic object on the door of the vehicle.
7. Attach the flexible clamp to the ring of the metallic mounting while revolving the Door-o-Meter toward the mounting.

OPERATION
TIMER MODE
This mode allows for the verification of the opening and closing times of the panels.
1. To start the device, place the right-hand momentary switch to the start (marche) position. The state of the battery and the program version number are displayed for 2 seconds. For reliable readings, use the device only with properly charged batteries.
2. Once the device is on, the display appears on the screen. See Figure A5. The Door-o-Meter is now in timer mode.
3. To test the opening time, place the left-hand momentary switch in the sensor (capteur ir) position and activate a door-opening cycle. When the door is completely open, the display indicates on the first line, in the following order, the air reaction time and the time associated with the movement of the door-opening until damping. See Figure A6.
NOTE
A maximum delay of 10 seconds is allocated to detecting the start of the air reaction time, and a maximum delay of 5 seconds is allocated to the movement of the door opening. The delay of 10 seconds allows the operator to adjust the command for the front door opening. If one of the delays is exceeded, the screen on the device displays an error and returns to its default setting.
4. To test the closing of the door, place the left-hand switch in the sensor (capteur ir) position and activate a door-closing cycle. When the door is completely closed, the second line on the display indicates the following, the air reaction time and the time associated with the movement of the door closing until it reaches its initial position. See Figure A6.

The delay of 10 seconds allows the operator to adjust the command for the front door opening. If one of the delays is exceeded, the screen on the device displays an error and returns to its default setting.
NOTE
If there is slippage between the rubber wheel and the ball joint, corresponding to 45 % or more, relative to the initial position, the word slippage (glissement) appears momentarily on the second line of the display
5. To conduct a new test, ensure that the door is in the closed position and repeat the previous steps.
NOTE
In the TIMER mode, the device automatically stops after 10 minutes of inactivity.
NOTE
If the device starts a test where the flexible rubber wheel is not properly oriented, it is possible that the movement of the shaft is not sufficient to trigger a measurement of the timing of a door opening cycle. Stop the device, reorient the wheel and restart the test.
