Left/Right Movement

When a selected mirror is moved to the left by the Mirror Adjustment Switch (X146) the internal contacts move to the "Move Down or Left" and the "Move Left" positions. The Left/Right Motor of the selected actuator is grounded at e201 through the SW wires and the switch contacts. Voltage is applied to the Left/Right Motor through the BP, BU wires. The mirror now moves left.

When a selected mirror is moved to the right by the Mirror Adjustment Switch (X146) the internal contacts move to the "Move up or Right" and the "Move Right" positions. The Left/Right Motor of the selected actuator is grounded at E201 through the BU, BP wires and the switch contacts. Voltage is applied to the Left/Right Motor through the SW wires. Since the polarity of the voltage to the motor has been reversed, the mirror now moves right.
