Aerial Loading
Single transducer installation:
The transducer (PN 102606) must be installed in the pressure feed line to the
actuating cylinder(s) or where it can sense the hydraulic pressure necessary to
lift the aerial device.
Supply 12 VDC and ground to the display.
Route the transducer wiring from the display to the transducer and plug in the
connector.
If an audible alarm is desired, connect the alarm output (ground) from terminal #1
of the 8 pin display connector to the ground side of the alarm. An alarm test
switch may be connected from ground to terminal #8 of the display connector.
Dual transducer installation:
Identical to a single transducer installation with the addition of a second trans-
ducer that should be installed on the rod side of the hydraulic actuator. This
transducer signal is read at terminal #7 of the display connector.
