Electronic Actuation Installation
Wiring the AO-E Module and differential pressure
transmitter to the Fume Hood Controller.
The Electronic Actuator is provided with a pre-wired
connector that is attached to the AO-E module on
the J4 terminal.
1. Remove the equipment enclosure cover by
loosening the quick release butterfly fasteners.
The butterfly fasteners will remain attached to
the cover.
2. With the equipment enclosure cover removed,
locate the AO-E module and the differential
pressure transmitter. (Figure 9).

3. Wire the AO-E module to a source of 24 Vac
power to terminal J1 using 18 AWG or larger
wires.
4. Connect the wire from the AO-E module terminal
block J2, to the FHC board terminal block TB3
using a 20 AWG cable. (Figure 10).

The Lab Controls Electronic Actuator
Assemblies can be on the same power
trunk as the FHC, LRC or on a separate
