Tips: Nema 8 micro stepper motor maintenance.

Zero excitation maintenance: maintain the Nema 8 micro stepper motor with an excitation circuit formed by a current relay.
Over-voltage maintenance: maintain the Nema 8 micro stepper motor with an armature circuit composed of over-voltage relay.
Overload protection: use an armature circuit composed of a current relay to maintain the Nema 8 micro stepper motor.
Overcurrent protection: use an armature circuit composed of overcurrent relay to maintain the Nema 8 micro stepper motor.
Grounding maintenance: Use a grounding device formed by voltage relay to maintain the Nema 8 micro stepper motor. When any point of the DC motor is grounded, the voltage relay will act to send out a warning signal or cut off the power supply.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
