Aerial Loading

Aerial manufacturers must ensure that the lift cylinder(s) do not bottom out
during operations. This would cause an erroneous hydraulic pressure read-
ing and the warning system will not operate as designed.

Dual Displays

The

Class1

Dual Current Amplifier (PN 103282) should be used when-

ever two displays are operated from one current transducer (aerial load-
ing, air pressure and oxygen gauges)

.

A harness is available to simplify the installation (PN 103283)
