OPERATION
Installation
Mechanical
52120:
The 52120 can be installed indoors
or outdoors.
52121:
The 52121 is designed for installa-
tion in control panels or similar
applications. To install the 52121,
follow these instructions:
1. Drill a hole (diameter at least 6.5
mm, 9/32 in) for the axle of the throt-
tle knob. Pull the throttle knob and
the graduated dial face off the unit.
2. Drill two holes for the mounting
screws. Insert the axle of the throttle
knob from below through the hole
drilled in step 1. Use two M3 screws
to secure the throttle from above.
Attention! The screws must not pro-
trude more than 4 mm (3/16") from
the heat sink. If they protrude further
or press on the circuit board, the cir-
cuit board will be damaged.
3. Glue the graduated dial face onto
the face of the control panel and
press the throttle knob onto the
throttle.
Attention! Make sure the heat sink is
ventilated. If the throttle is installed
in a closed housing, provide ade-
quate ventilation holes. When
installing several throttles 52121
next to each other, make sure there is
a space of at least 5 mm between the
heat sinks.
Electrical
The throttles can be connected to AC
or DC power from any LGB power
supply. An internal circuit automati-
cally detects the power type and con-
