CAUTION:

When you lock the gear train lock pin, be careful to turn only about 5 degrees until you hear a light
click or meet slight resistance. Turning too far will strip the head of the lock pin. Once power is
restored, the actuator returns to automated control, without having to rotate the gear train lock pin.

Mechanical Range Adjustment –
Limiting Rotation (0 through 90°)

Make sure the actuator is in the zero position when
making this adjustment. If making the adjustment
before the actuator is in service, take into account the
5° preload. To release the preload, insert the 3 mm hex
key in the override opening and turn the key in the
direction of the arrow.

To line up the actuator at the desired angle of rotation,
begin by removing the clamp from actuator.

Rotate adapter and insert at desired angle of rotation.
Return clamp to secure the adapter. Test rotation by
applying signal.

If necessary, re-adjust adapter and restart.

• After setting the 4th DIP switch for TM (tandem mount) on all actuators used in the
tandem application, one actuator must be identified as the Master by selecting the
"M" on the 5th DIP switch.

• The rest of the actuators used in the application should have the "S" (slave) set on
the 5th DIP switch.

• Connect all the 2 (black) Neutral wires and connect them to the power supply.

• Connect all the 1 (red) Supply wires and connect them to the power supply.

• The Output Signal 9 (pink) wire identified as the Master actuator, needs to be

connected to all the Control Signal Wires 8 (gray) of the slave actuators used in the
tandem application.

ES142 Spring Return Electronic Actuators

Wiring

24 VAC or 120 VAC

All wiring must conform to NEC and local codes and regulations.

24 VAC

Use earth ground isolating step-down Class 2 transformers. Do not use auto transformers. Determine the supply
transformer rating by summing the total VA of all actuators used. The maximum rating for a Class 2 step-down
transformer is 100 VA. The ES142 (24 VAC) actuators require 8 to 9 VA; therefore it is recommended that up to
10 actuators (between 80 and 90% of transformer VA) can be powered by one transformer. Operating more than
10 actuators requires additional transformers or separate 100 VA power trunks.

WARNING:

Mixed switch operation is not permitted. To the switching outputs of both auxiliary switches (A and B),
only apply:

• Standard cable (250 Vac/24 Vdc)

− UL/cUL: line voltage, or

− UL/cUL: Class 2 voltage.

NOTE: Either all six outputs of the dual auxiliary switches must be connected to line voltage or all six

outputs must be connected to Class 2 voltage.

• Plenum cable (24V)

− UL/cUL: Class 2 voltage.

Sizing Actuators for Damper Applications

The number of actuators required depends on several factors. To determine the quantity of actuators required for
the installation:

1. Obtain damper torque ratings (ft-lb/ft

2. Determine the area of the damper.

3. Calculate the total torque required to move the damper:

Total Torque = Torque Rating x Damper Area

4. Select the total quantity of actuators, required:

Number of Actuators =

Total Damper Torque required

SF

(see note

below)

2

or Nm/m2) from the damper manufacturer.

x

Actuator T orque

(refer to

specifications)

NOTE: When calculating the number of actuators required, a safety factor (SF) should be included for

unaccountable variables such as slight misalignments, aging of the damper, etc. A suggested
safety factor is 0.80 (or 80% of the rated torque).

Mechanical coupling of the actuator is allowed if:

• The same type of actuator is used.

• The operating voltage is within the tolerance.

NOTE: The auxiliary switches and/or the control signal adjustment cannot be added in the field. Order the

product number that includes the option(s), if required.

ASK71.1U This kit allows foot mounting of the ES142

actuator. This kit should be used for
in-the-airstream applications, and generally, anywhere
a foot-mounted actuator can be mounted.

This kit contains a crank arm that changes the angular
rotation into a linear stroke, a support bearing ring to
minimize side loading on the actuator’s output bearing,
a mounting bracket, and required mounting fasteners.

ASK71.2U This kit allows mounting of the ES142

actuator directly to a damper frame. This kit should be
used with louvers and vents, and in applications where
use of the floor mount kit is not possible.

This kit contains a crank arm that changes the angular
rotation into a linear stroke, a support bearing ring to
minimize side loading on the actuator’s output bearing,
a mounting bracket, and required mounting fasteners.

ASK71.3 This kit allows a direct coupled actuator to

provide an auxiliary linear drive. This crank arm kit can
be used to simultaneously drive a set of opposing or
adjacent dampers with a single actuator.

This kit includes a crank arm that attaches to the
splined hub of the shaft adapter, and other required
mounting fasteners.

ASK71.4 This kit allows economical mounting of an

actuator to a variety of surfaces. This kit should be
used in applications where the actuator can be rigidly
surface mounted and a linear stroke output is required.

This kit includes a crank arm that attaches to the
splined hub of the shaft adapter, a mounting bracket,
and other required mounting fasteners.

ASK73.1 This bracket provides an extended anti-

rotation pin that allows two ES142 actuators to directly
drive a single damper shaft. For use with two and
three–position actuators.

ASK73.2U This bracket provides an extended anti-

rotation pin that allows two modulating actuators to
directly drive a single damper shaft. (Applicable for
standard models and models with dual auxiliary
switches; not applicable for zero span control signal

Special shaft adapter.

985-004 The self-centering shaft adapter will attach to

a shaft up to 1.00 inch (25.4 mm) in diameter. (The
special shaft adapter will attach to a 1.05-inch
(26.6-mm) diameter shaft.) This shaft adapter is
13/16-inches (20 mm) taller than the height of the

special shaft adapter.
