Actuator Commissioning Tool

Item Number 129-287, Rev. 100 Page 1 of 8

Product Description

The 985-047 Actuator Commissioning Tool provides
a portable instrument for exercising, calibrating, and
testing resistive, proportional (voltage/current),
floating, and on/off actuators. LED display shows
feedback voltages or output. LEDs indicate
operating mode selection and auxiliary switch
contact closure. The Commissioning Tool combines
accurate and reliable technology in a user-friendly,
yet economical package.

The Commissioning Tool saves on installation time
and is compatible with all Siemens actuators and
most competitors’ models. A plug-in transformer or
24 Vac power supply input enables the
Commissioning Tool to output resistance,
AC voltage, DC voltage, and current for controlling
an actuator. It requires no controller hook-up, which
makes equipment calibration, setup, and adjustment
a quick and easy process.

Installation Conventions

WARNING

Personal injury/loss of life may
occur if a procedure is not
performed as specified.

CAUTION

Equipment damage, or loss of
data may occur if the user
does not follow procedure as
specified.

Blocks.

Application Overview

The Actuator Commissioning Tool has
four pushbutton selectable modes of operation as
follows:

Table 1. Output Control Signal Features.

Mode of

Operation

Description

Resistive *

0 to 135 ohms or 0 to 1k ohms for
use with resistive input actuators.

Voltage

0 to 20 Vdc for use with
proportional actuators

Current

0 to 20 mA for use with
proportional actuators

Floating Control

24 Vac (nominal) for use with
floating control and on/off
actuators

* The resistive mode is the default operating

mode when the commissioning tool is not
powered. To select other operating modes, the
ON/OFF switch must be turned ON. LEDs
indicate which mode is active.

The Commissioning Tool also provides additional
testing features as follows:

Table 2. Additional Testing Features.

Feature

Function

Power for Actuators

A 24 Vac (nominal) signal is
provided to power actuators that
are not externally powered.

Bias (for feedback
potentiometers)

A 5 Vdc bias signal is provided
through a 330 ohm resistor for
resistive feedback testing (for
feedback potentiometers).

Voltmeter

Measures 0 to 30 Vdc signal.

Switch Testing

LEDs display auxiliary contact
closure.
Use with dry contacts only!

The Commissioning Tool receives power by either:

• Applying 24 Vac (nominal) to the INPUTS

terminal block, or

• Connecting the 120V plug-in transformer

(provided) to its power jack.

Operation

WARNING:

Shock Hazard.
Disconnect all power supplies to the
Commissioning Tool and actuator or control
device before wiring to avoid possible
electrical shock or equipment damage.

Powering Commissioning Tool

CAUTION:

Equipment Damage Hazard.

Contact with water may result in damage to
the Commissioning Tool.

1. Apply 24 Vac (nominal) power from a remote

transformer or controller to Terminals 8 (COM)
and 9 (24 Vac) of the INPUTS terminal block on
the Commissioning Tool.

Or connect the plug-in 24 Vac transformer
(provided) to the power jack located on the
bottom of the Commissioning Tool (Figure 4).

Figure 4. Applying Power to the Commissioning Tool.

2. Turn the Commissioning Tool power switch,

located on the lower left side, to the ON
position. The green LED at the bottom left
corner of the Commissioning Tool lights,
indicating that the Commissioning Tool is
powered.

CAUTION:

Equipment Damage Hazard.

This device is only 24 Vac nominal. Applying
higher voltages could damage the device.

Powering a Non-externally Powered
Actuator or Control Device

CAUTION:

Equipment Damage Hazard.

Controlled equipment loading from Terminals 1
and 2 must be limited to 25 VA maximum.

NOTE: For 115-230 Vac actuators, the

Commissioning Tool can be used to
provide signal, but must be externally
powered.

1. To provide a 24 Vac (nominal) power signal,

connect Terminals 1 (24 Vac) and 2 (COM) of
the OUTPUTS terminal block on the
Commissioning Tool to the supply input
connections of the actuator or device being
powered (Figure 5).

NOTE: The output signal at Terminals 1 (24 Vac)

and 2 (COM) is equivalent to the input
signal that powers the Commissioning
Tool.

Figure 5. Connecting External Power to an Actuator

or Control Device.

Resistive Mode ()

CAUTION:

Equipment Damage Hazard.

Use the Commissioning Tool Resistive Mode
with only solid-state actuators and control
devices. Use with electromechanical devices
will cause damage to the Commissioning Tool.

The resistive mode can be used with or without
power supplied to the Commissioning Tool. When
power is not supplied to the Commissioning Tool,
the resistive mode is active. When power is initially
supplied to the Commissioning Tool, it defaults to
the resistive mode.
