SmartJack V4.0 Installation
Motor Rectifier Issues If the opener will not open or close and an audible click can no longer be heard when the opener was commanded to open or close. The opener could have a rectifier that is not working properly. To see if rectifier is the problem, meter the two wires coming into and out of the rectifier located in the wiring box on the motor. The two leads coming from the main control box on the side of the rectifier is the incoming voltage and should meter 200VAC (when the opener gets an open or close command). If it doesn’t meter 200VAC, there is a problem with the relay in the main control cabinet. If there was 200VAC above, then check the other wires (with command) that go out of the rectifier to the armature (inside wires). This should meter 200VDC. If they do not, the rectifier needs replacement. Brake Failure Check to see if you are getting 220 V across the brake leads at at the motor- That is the 2 terminals with the alternating current symbols or sideways “S” ( Outide Terminals ( some units they are labeled 1 & 2.-V3 units) If you are getting voltage, You could have a bad rectifier. Motor Issues Disconnect the motor from the terminal block where field wired, turn the power on and see if the breaker trips.
Ohm each leg to the ground of that motor to see if it is shorted internally Run it without the motor disconnected to see if there is a VFD outputs voltage.
PLC Reset- (Run versus Idle) At times, due to a brown-out or interruption in power, the PLC may go into an “Idle mode”. This will cause the opener to show errors that seem to have been corrected or show inputs that are not consistent with the actual situation. Similar to an old stick shift truck that slips into neutral by accident, the unit will not operate properly until it gets put back into drive. Here’s how to identify the mode it is in and how to correct it if it is incorrect. • Go to LED Screen on the PLC and hit both “Up” and “Down” arrow at the same time to get the main screen. • Toggle with arrows to the “View Status” screen and press enter. • Toggle with arrows to the “Mode”, screen, press enter. If the “Mode” shows “RUN” on the screen, your PLC is set up correctly. Exit out of the screen. If the “Mode” shows “Idle” on the screen, your PLC needs to be changed to “Run”. To do this… Press “Enter”, toggle with arrows to “Run”. Press “Enter” to accept. Exit out by pressing the “F2” or “escape” button. Your PLC should now be in “Run” mode.
If you want to reset the date and other parameters hit the both the up and down key at the same time. You will get another menu look from there……
