3.3.5 Speed Indicator : LR524 (single-indication) and LR525 (dual-
indication)
This is a large analog indicator with an outside diameter of 180 mm. EL-plate lighting is employed,
and two types of dimmers, a built-in dimmer (for wall-mounted models only) and an external dim-
mer (LD001A), are available. This indicator receives digital signals from the master unit, and reads
the analog speed by using the pulse motor.
