How the tester module works?
Steps to follow
1. Connect the injectors to the module as shown in the figure
There is no polarity in the injector’s two terminals.
2. Connect the battery to the module as shown.
If it is connected correctly, all the indicator lamps will be blinked up and the buzzer sound will be heard twice after initialized the module.
3. Select the desired pulse frequency by pressing the touch key of
(FREQ). The module will excite the injectors with pulses of a 50% Duty cycle.
4. Select the desired operating period by pressing of the touch key of
(TIMER). The module will apply the selected pulse frequency to the Injectors for the selected period.
If you selected the (CONT) mode, the timer function will be disabled and it will be excited the injectors with the selected frequency until you stop it manually by pressing (STOP).
5. After selecting the mode press (START) button to start the exciting process. The lamp (ACTIVE) will be blinked while the module is in operation. When the operation is completed the buzzer bleep will be heard twice and the lamp (ACTIVE) goes off.
-If (POWER) lamp blinked with the buzzer continuously in some-where of the operation, it indicates applied power to the module is low. Correct it and restart the process.
-If there any short circuit or over current flow occur in the output cables or inside any injector, the module will be muted with no indication.
If such situation occur;
1. Press (RESET) button to reset the module.
2. Recheck the wiring.
3. If no miss wiring observed, check the injectors individually with the aid of a multi meter in order to find out the short circuited one. Such injectors would be faulty and to be replaced.
