Ask Hytrol: How to Calibrate the Electric Lift

Posted by Whitney Blackburn on Mar 29, 2016 7:00:00 AM

 

This calibration requires the use of the DIP switch functions. If you would like to review these functions, please watch our earlier video in which we summarize them. 

First, set switch 1 to your desired gear-reducer shaft rotation. Then, set switch 4 to the OFF position to select the calibration mode.

Now, apply power; the amber LED will be on, which indicates that the electric lift is in calibration mode. Remember that any dip switch changes will not take effect until the power is cycled.

Use the Jog momentary push-button located on the right side of the 3-position motor connector to make at least one complete revolution of the output shaft before completing the next step. The motor runs while Jog is pressed.

Use the Jog to put the lift in its UP position. In this position the shaft is aligned so that it is mechanically locked. This reduces stress on the motor. Now, once the lift is in its UP position, press the Mark switch located to the left of the 3-position motor winding connector to set this position. Upon releasing the Mark switch, the amber LED will flash once to indicate that the UP position has been set successfully.

Use Jog to move the lift to its DOWN position. Once the lift is in that position, press Mark to set it. Upon releasing the Mark switch the amber LED will flash twice to indicate the DOWN position has been set successfully.

When the calibration data has been stored, the amber LED will flash 3 times to note that the position information has been stored in the control’s memory.

Now, power down and move DIP switch 4 to the ON position for normal control operation. Reapply power to the system. You may test the operation by holding the Jog button.

Ask Hytrol: DIP Switches and Pin Functions for the Electric Lift

Posted by Whitney Blackburn on Feb 23, 2016 7:00:00 AM

 

Hytrol’s o-ring transfer includes four DIP switches. For the DIP switch functions, switch 1 is at the top, and the left is the OFF position.

Switch 1 sets the rotation direction for the gear reducer shaft. OFF sets the rotation clockwise, and ON sets it counter-clockwise.

Switch 2 is the control current limit setting. Set the switch to OFF for low current and ON for high current and faster cycle rates. Note that the ON position will use more power.

Switch 3 is not in use at the time of this video.

Switch 4 sets the mode of operation; OFF is for calibration mode while ON is for normal operation.

Pins for I/O functions run left to right, where Pin 1 is the leftmost.

Pin 1 is for the RUN1 input; the lift moves to the UP position when the RUN1 signal goes from Low to High. The lift moves to the DOWN position when the RUN1 signal goes from High to Low.

Pin 2 is the UP output. High indicates the lift is in the UP position.

Pin 3 is the DOWN output. High indicates the lift is in the DOWN position.

Pin 4 is the TRANSFER RUN output; this signal is used to tell the Transfer Control Card to run.

Pin 5 is the NO FAULT output, which indicates that there is no control fault.

Pin 6 is the GROUND power supply connection for use with external wiring.
