Replacement Instructions
Electronic Actuator – Terminal Unit
Installation
1. Remove the cover on the enclosure.
2. Remove the AC power to the unit (J1).
3. Remove the terminal block that connects the
actuator to the LEA Interface board (J5).
4. Remove the hitch pin and clevis pin from the
crank arm assembly (see Figure 1).
5. Using needle-nose pliers, remove the e-clip
from the pivot post.
6. Remove the actuator from the pivot post.
7. Place the new actuator on the pivot post as
shown in Figure 1 and install the e-clip on the
pivot post.
8. Rotate the actuator shaft counterclockwise no
more than ¼ turn to line up the actuator with the
crank arm.
NOTE:
The actuator start position has been factory
set. To reset the start position for a terminal
unit, rotate the actuator shaft fully
clockwise until it is at its full end position.
Then rotate the shaft counterclockwise no
more than ¼ turn until the shaft hole aligns
with the clevis pin and the crank arm.
The shaft is only to be turned to reorient it
from horizontal to vertical, or vice versa.
Over turning the shaft causes damage to
the actuator.
If the actuator shaft does not align with the
clevis pin and crank arm, the linkage must
be adjusted until it is aligned.
9. Install the clevis pin through the proper hole in
the crank arm and actuator.
10. Secure the clevis pin with the hitch pin.
11. Install the terminal block that connects the
actuator to the LEA Interface board (J5).
12. Install the AC power to the unit (J1).
13. Perform the steps in the Section 5 – Functional
Verification before using the LEA
Interface/electronic actuator assembly.
14. Replace the cover on the LEA Interface/Actuator
enclosure.
Installation of the replacement actuator is complete.
LEA Interface Board
1. BEFORE accessing actuator enclosure, set DIP
Switches on replacement board (Figure 8),
referring to Table 1 and Table 2. For actuators
in fail-safe application, pay particular attention
to SW2, position 3, which sets the fail-safe
position.
2. Remove the cover on the LEA
Interface/Actuator enclosure.
3. Remove the AC power to the unit (TB J1).
4. Remove the terminal blocks from the actuator
and the controller (J2 and J5).
NOTE:
Wear a wrist strap to limit the possible
damage caused by Electrostatic Discharge
(ESD).
5. Remove the LEA Interface Board from the snap
track and replace with the new LEA Interface
Board.
6. Install the terminal blocks from the actuator and
the controller (J2 and J5).
7. Install the AC power to the unit (TB J1).
8. Perform the steps in the Section 5 – Functional
Verification before using the LEA
Interface/electronic actuator assembly.
9. Replace the cover on the LEA Interface/Actuator
enclosure.
Installation of the replacement LEA Interface board
is complete.
