verify that the switches are set as shown in
Figure 3:
Figure 3. Switch Setting for Fast Acting Lab
Electronic Actuation.
CAUTION:
This actuator requires a maximum of 20
VA, 24 Vac source. DO NOT connect
any other non-isolated devices to the
transformer that powers the electronic
actuator or the hot water valve actuator.
9. Plug the room temperature sensor cable into the
RTS port on the controller (Figure 1).
10. Connect a certified 24 Vac Class II power
source to the LCM-OAVS’s power supply
terminal block.
The installation is complete.
Figure 4. Power trunk connection.
NOTE: As a standard grounding procedure, ensure
that a ground wire is connected directly from
neutral of the 24 Vac secondary (the side
that connects to the "C" terminal of the TEC)
to earth.
CAUTION:
It is very important that the neutral that
supplies the TEC be earth grounded at
the source of the 24 Vac power.
