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

This guide provides step-by-step instructions for installing and configuring the MSL2-120GR MicroStat™ Status Indicator on a suitable mounting surface.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Gasket

  1. Unpack and Inspect the Equipment

    Carefully unpack the MSL2-120GR 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 to unlock it. Lift the lens off and retain the O-rings. Remove the two Phillips head screws to disassemble the sleeve from the base. Mount the base onto a flat surface using the gasket as a guide, marking and drilling the necessary holes. Secure the base with appropriate screws, ensuring not to over-tighten.

  3. Make Electrical Connections

    Remove the terminal block plug from the printed circuit board assembly. Feed the control wires through the NPT opening in the base and connect them to the labeled female terminal block plug. Ensure the connections correspond to the correct 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 and secure it with the screws removed earlier. Reassemble the colored lenses onto the base, ensuring each lens is sealed with an O-ring.

  5. Test the Installation

    Before applying power, double-check all connections and ensure that the unit is securely mounted. Once verified, apply power to the system and test the MicroStat™ to ensure it operates correctly.
