3.2.1 Fitting an Adaptor Board to a MagMaster
To fit an adaptor:
1. Turn off the power to the MagMaster and remove the covers – see Fig. 3.1.
2. Remove the wiring from the terminals. Slacken the terminal screws by at least 6 turns.
3. Carefully ease the sensor wiring to one side and fit the adaptor board so that the extended
pins fit into the terminals – see Fig. 3.2. Tighten the terminal screws.
4. Fit and tighten the securing screw to the corner of the adaptor board.
5. Connect the sensor cable leads to the adaptor plug – see Fig. 3.3. Do not fit the plug to the
socket on the adaptor board.
Note. The newer series (VKH) MagMaster does not need to have this adaptor board fitted as
one is already incorporated into its design.
