4 1.1. Definitions WARNING: If not observed, user incurs a high risk of severe damage to product and/or fatal injury to personnel. CAUTION: If not observed, user may incur damage to product and/or injury to personnel. NOTE: Advisory and information comments provided to assist maintenance personnel to carry out maintenance procedures. 2. Operation principal It is improved driving mechanism for opening/closing the door of the buses. It is featured with compact structure, fine performance and long life service. It uses electrical as well as pneumatic systems for opening/closing of the door. Pneumatic control systems can be designed in the form of pneumatic circuits. A pneumatic circuit is formed by various pneumatic components, such as cylinders, directional control valves, flow control valves, etc. Pneumatic circuits have the following functions: 1. To control the injection and release of compressed air in the cylinders. 2. To use one valve to control another valve. Similarly, Electric control systems can be designed in the form of electric circuits. An electric circuit is formed by various electric components, such as micro processor, switches, control box etc. Electric circuits have the following functions: 1. To control the controller operation. 2. To trigger the solenoid valve. RTX-IOM-BDOS-R Page 4 of 18

5 3. Identification 4. Installation procedure The equipment must be installed in the accordance with the laws, guide lines and rules applicable within the country. CAUTION: Do not dismantle the cylinder while operation is in line. Do not allow dirty air or fluids to get into the cylinder. NOTE: Ensure the installation meets the legal and regulatory requirements of the country and state of use. The door assembly should be left in the original packing until it is required for the use. Operating pressure range 4-10 bar. Operating temperature range -20 C to +80 C Check the components as per packing list before installation. Make sure that sealing gasket and glass have been installed on the door panels. RTX-IOM-BDOS-R Page 5 of 18

8 1. First install top mounting plate assembly by mounting the screw through plate into the bus frame at its position as per drawing. 2. Install the sealing gasket on bus frame. Fix it using stiffener plate with self tapping screw. RTX-IOM-BDOS-R Page 8 of 18

9 3. Mount the bracketed support shaft perfectly vertical by pushing shaft head into bearing of the mounting plate and tight the bracket at the bottom. 4. Mount the brackets and handle on the door panel as per the drawing. And then install the door panel on the bus frame one by one by mounting door panel into arm brackets of door shaft.

10 5. Install the guide rollers properly, to align door with structure to avoid gap adjust eccentric roller shaft. 6. At last install the brush. 7. Manually close and open the door to check its smooth movements. 8. Connect the pneumatic tube and electrical wire as per drawings. 9. Open and close the door automatically to check whether the door moves smoothly. If needed, adjust the speed and cushioning. Initial adjustment When door closes, disconnect its connection with cylinder. Pull the cylinder rod outside 5 mm approx and again join the disconnected connection. Now close the door. This will ensure tight closing of the door. Locking position After initial adjustment, mark the locking position at closed door position. RTX-IOM-BDOS-R Page 10 of 18

12 5. Maintenance NOTE: ROTEX recommends ROTEX V09 grease for greasing. Apply the grease with soft brush or similar. In case of any difficulty consult ROTEX distributor. 1. Install, operate and maintain as per the instructions and recommendations of this manual. 2. Observe grease layer on moving parts weekly. 3. While observing apply grease on the moving parts if necessary. 6. Characteristics parts 6.1. Cylinder Ø63/100 Function: Drive the door to open and close Specification: Working Medium Filtered compressed air (Min 50µ) Pressure range 1 10 bar Front fixing Ball & Socket joint Rear fixing MP4 Ambient temp. -20 C to +70 C Cushioning adjustment Both ends 6.2.

15 6.7. Anti Pinch Sensor (PDV) Function: Whenever there is any obstruction at the door, due to the difference of air pressure in the cylinders, the mechanical switch operates and that signal is sensed by the controller thus making the door retract automatically Beeper With Indicator Function: During the door closing, the buzzer beeps to warn the driver. And also in case of emergency the beeping frequency changes to warn the driver. RTX-IOM-BDOS-R Page 15 of 18

16 7. Trouble shooting No. Trouble Cause Solution Leakage in cylinder Tight the fittings. 1. Door not working Emergency Switch System Reset problem Ant pinch function not working Door open/close either too fast/slow. Solenoid valve failure. Controller wiring harness is damaged. Check the on/off switch on the dash board for proper functioning. Low pressure at the main cut off valve Continues air exhaust but not achieved emergency condition. Pressures switch connection loose. PDV sensor connection loose Flow control not adjusted. Cushioning screw adjustment. Check as per manual/replace. Correct the harness connection. Check the connections and wiring/check on/off switch contacts/ replace the switch. Start the engine to build pressure or else check for bending in pipe line. Check button (Manual condition) of SDAJ213 (Reset valve) whether it is in pressed condition. It should be in unpressed condition only. Check the connection of pressure switch. Correct the connection of PDV sensor on cylinder. Rotate the knob of the flow control to adjust the air flow. Adjust the cushioning screw to avoid jerks during door close/open.
