Introduction
Use this guide for the EIS jumper modification for the following SKUs:
-SKSNG166D4T
-SKSNG204D4T
-SKSNG447D4T
This modification is required for the above SKUs. Professional installation is and substantial board-level soldering experience is required. If needed, Mid City Engineering or a distributor will perform the modification. Please contact Mid City Engineering at 312-421-1114 for more information.
-
-
Remove 2 screws on back of EIS housing
-
Carefully open EIS housing
-
Before beginning this modification, be sure that you are using a temp. controlled soldering iron and have substantial board-level soldering. This procedure deals with sensitive components.
-
-
-
Add pin
-
-
-
Add solder to contact near optical sensor
-
Do not overheat. Damage to optical sensor and other components is risked.
-
-
-
Attach wire to pin that was inserted in last step
-
-
-
Solder other end of wire to contact where solder was added near optical sensor in step 3
-
-
-
Use hot glue to secure wire in place
-
-
-
Drill hole in rear cover of EIS to route cable
-
-
-
Route bare end of cable through hole drilled in previous step. The bare wires will be connected to board
-
-
-
Apply glue and adhere cable in place on board of EIS
-
-
-
Put additional glue on top of cable to further secure in place
-
-
-
Add solder to contacts where cable will be connected to board of EIS

-
Solder blue wire to contact on board
-
-
-
Add solder to next contact point
-
-
-
Solder black wire to contact in previous step
-
-
-
Add solder to two (2) additional locations on board
-
-
-
Solder red wire to contact point
-
-
-
Solder green wire to contact
-
-
-
Add solder to additional point
-
-
-
Solder white wire to contact
-
-
-
Use additional glue to secure wires to board
-
-
-
Carefully put board and cylinder back in housing and re-assemble case and screws
-
-
-
Testing modifications to confirm functionality
