4. onding full range joystick movement If the indicator is working properly and the outputs are not working properly the speed controller is probably damaged The final test to determine if the Victor is damaged is to replace it with another Victor Indication No power output from the speed controller and the indicator does NOT work Problem No input power or possible internal damage Possible Solutions If the indicator on the Victor is not operating properly and there is no output the Victor may be internally damaged This condition is typically caused by no input power or a reverse polarity on the input Check the following 1 Disconnect the output wires 2 Ensure the indicator on the Victor will not illuminate at any joystick position 3 Check the input at the Victor BATTERY to GND with a voltmeter If the indicator is not working properly and the input is good the speed controller is probably damaged The final test to determine if the Victor is damaged is to replace it with another Victor CAUTION Prior to replacing a potentially damaged speed controller ensure that the wires connected to the output are not shorted and the input is not reversed Also verify that neither of the motor output leads are shorted to the chassis of the motor and or the robot APPENDIX A Document Version History Date Code Changes 1 26 05 Revised Brake Coast Section 9 25 06 Revised Brake Coast Section Page 2
5. rly connected Check wire color coding at each end Check that the connector is not off a pin at the receiver end 3 Check for a good PWM signal by connecting a known good servo to the PWM extension cable If the servo does not move this can indicate either a a faulty receiver b an improperly connected cable c abad PWM extension cable Note The servo requires that 5V be present on the center pin of the PWM cable This connection is not required for the Victor Indication Flashing RED indicator after calibration Problem Calibration Failed Possible Solutions 1 Inadequate travel in forward or reverse Repeat the calibration procedure and move the joystick further forward and or further reverse 2 The joystick trim tab is NOT centered Neutral cannot be extremely far from center Indication No power output from the speed controller although the indicator LED works Problem Possible internal damage Possible Solutions If the indicator on the Victor is operating properly and there is no output the Victor may be internally damaged This condition is typically caused by a short circuit on the output or there has been an over current condition to caused a failure Check the following 1 Ensure the indicator is changing between ORANGE RED and GREEN with joystick movement 2 Disconnect the motor and check the output M to M with a voltmeter The meter should read between Battery voltage with corresp
6. to coast during operation A limit switch may be connected to the jumper connector instead of the jumper The limit switch can be triggered by various means including the use of a servo Brake Coast Guidelines Reference Diagram 1 The jumper should always be installed If you lose the jumper a standard computer jumper will work 2 The Coast condition Jumper on Inner two Pins sets the output to an open circuit during neutral 3 The Brake condition Jumper on Outer two pins sets the output to a short across the motor leads during neutral IFIROBOTICS 12V Victor 884 25 Sept 06 www lIFlrobotics com Users Manual Page 3 Troubleshooting Indication No ORANGE indicator on power up Problem Input power issue or joystick trim tab off center Possible Solutions 1 Disconnect PWM cable 2 If indicator blinks ORANGE the PWM value that was being received is either between neutral and full forward or between neutral and full reverse Check joystick trim tab to ensure the controller is not in a partial forward or a partial reverse condition If no change check that the joystick and receiver channels match 3 If indicator remains off check V or GND connections for voltage and proper polarity Indication Flashing ORANGE indicator on power up Problem No PWM signal Possible Solutions 1 Ensure the transmitter and receiver are powered ON 2 The PWM cable may be imprope
7. ur receiver is Victor compatible if you are not using an IFI Control System 3 The male PWM cable connector connects to the speed controller The Victor housing is design to provide a firm connection Trim the shroud corners slightly if necessary for insertion into the Victor The PWM extension cable should be installed with the black wire towards the fan Standard Radio Controlled PWM connectors are fragile Use caution when inserting and removing the PWM cable so the contacts on both connectors are not damaged Mounting Guidelines You will need 2 4 or 6 screws 1 The Victor can be installed in any orientation Sa gt 2 The speed controller must have adequate space above the fan for airflow a minimum of 2 inches ad Do not over tighten the mounting screws through the speed controller A snug connection will hold the speed controller in place without crushing the case Calibration Instructions The Victor is pre calibrated to values compatible with an IFI Control System and re calibration is not needed You can re calibrate to achieve full forward reverse from your joystick movement if necessary NOTE While in calibration mode the Victor will record the max PWM value detected as full forward the min PWM value as full reverse and neutral will be the PWM value recorded at the release of the Cal button The following steps will guide User Calibration 1 Power ON the speed control
