How to Install the MSL2-120BG MicroStat™ Status Indicator

This guide provides step-by-step instructions for mounting, wiring, and configuring the MSL2-120BG MicroStat™ Status Indicator.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Gasket

  1. Unpack and Inspect the Unit

    Carefully unpack the MSL2-120BG and inspect it for any damage that may have occurred during transit. If damaged, do not proceed with installation and file a claim with the carrier.

  2. Mount the Base

    Remove the colored lenses by twisting the bottom lens counter-clockwise until it unlocks. Lift the lens off the base. Remove the two Phillips head screws to disassemble the sleeve from the base. Mount the base onto a 3/4" NPT pipe or a flat surface using the appropriate screws, ensuring it is level and securely attached.

  3. Make Electrical Connections

    Feed the control wires through the NPT opening in the base. Connect the wires to the female terminal block plug, ensuring to match the terminals labeled '1' through '5' with the corresponding lamp positions. Reconnect the terminal block plug to the printed circuit board.

  4. Reassemble the Unit

    Ensure that an O-ring is in place on each light module. Reattach the sleeve to the base by sliding the printed circuit board into the channels and securing it with the screws. Reassemble the colored lenses in the desired sequence, ensuring each lens is locked in place.

  5. Test the Installation

    Before powering on, double-check all connections and ensure that all screws are tightened. Power on the unit and test the MicroStat™ to confirm it operates as intended.
