GENERAL INFORMATION

The AFP allows an analog (voltage or current)

signal to control a oating point actuator. It

converts an analog signal into two relay contact

outputs (one increase/one decrease). The isolated

oating point output can be controlled by any one

of nine analog input signal ranges (using an oset

jumper). Upon power-up, the decrease relay will

drive 100% of the chosen timing range to ensure

that the output is at its minimum position. On a

loss of power, the output relays will be open and

no signal will be generated. The actuator will

remain at the last commanded position unless it

has "spring return". The AFP output rate of change

(sixteen ranges, in eight versions) is DIP switch

selectable.

MOUNTING INFORMATION

Circuit board may be mounted in any position. If

circuit board slides out of snap track, a

non-conductive “stop”may be required. Use only

ngers to remove board from snap track. Slide

out of snap track or push against side of snap

track and lift that side of the circuit board to

remove. Do not ex board. Use no tools.

WIRING INSTRUCTIONS

PRECAUTIONS

• Remove power before wiring. Never connect

or disconnect wiring with power applied.

• When using a shielded cable, ground the

shield only at the controller end. Grounding

both ends can cause a ground loop.

• It is recommended you use an isolated

UL-listed class 2 transformer when powering

the unit with 24 VAC. Failure to wire the

devices with the correct polarity when sharing

transformers may result in damage to any

device powered by the shared transformer.

• If the 24 VDC or 24VAC power is shared with

devices that have coils such as relays,

solenoids, or other inductors, each coil must

have an MOV, DC/AC Transorb, Transient

Voltage Suppressor (ACI Part: 142583), or

diode placed across the coil or inductor. The

cathode, or banded side of the DC Transorb or

diode, connects to the positive side of the

power supply. Without these snubbers, coils

produce very large voltage spikes when

de-energizing that can cause malfunction or

destruction of electronic circuits.

• All wiring must comply with all local and

National Electric Codes.

SETUP

Analog input signal ranges are jumper selectable by using Jumper

J3, see Figure 3. The output of the AFP has two relays. One relay

controls UP (increase), the other DOWN (decrease) depending, of

course, on the actuator conguration. The rate of change these

outputs make on the actuator are determined by DIP switch SW1

setting. Refer to“Rate of Change” Chart and set switches according-

ly. Jumper J6 is to be in the CD mode at all times. Due to minor

dierences in the AFP timing range and product timing range, an

error may develop between the commanded position and actual

position of the actuator. There are two ways to calibrate the unit.

Input Signal Type

Moving jumper to ON adds offset

to the input or 1-5, 2-10, 3-15 or

4-20mA based on what range is

selected. OFF provides input

as selected on J3 above.

Jumper must remain

on CD setting

FIRST METHOD

Remove power (via control relay or switch). When power is removed

and reapplied the AFP will drive or stroke the actuator down 105%

of selected timing range (200% on Version 2, 105% up on Version 7).

Whenever the input on AFP Version 2 is within 2-5% of extreme up

or down, the relay will activate for an additional time that is 100% of

selected timing range. After the AFP has driven down (or up), it will

return to the position commanded by the analog level of the input.

The analog input can remain connected during a power reset. If the

accumulated error is greater than 5% and the analog signal at 100%,

this process may need to be repeated. Allow a 5 second or greater

delay before power is applied.

SECOND METHOD

The other way to calibrate the actuator is to drive the output to 0% and 100% of selected input range.

Depending the direction and amount of developed error, it may be necessary to repeat this process. This

calibration process should be done at a time when the large changes in the actuator position will not cause

problems with the environment it is controlling. When power is applied to terminals +24V and (-), the

“POWER” LED will light. When the AFP is not powered on terminals +24v and (-), both relays are open.

Tranzorbs are incorporated in the output circuit of the AFP.

TROUBLESHOOTING & TESTING

1.) Make sure the input and oset jumper and output timing switches 3 and 4.

2.) Apply 24 VAC/VDC to the 24 (+) and (-) terminals, conrm the power LED is on and measure

voltage to conrm proper voltage. A DC voltage can be measured from the Vout (+) terminal to the

24 (-) terminal. This voltage will vary depending on the supply voltage supplied. Voltage ranges will

be from 21 to 25 VDC. Please note supply and Vout voltages if unit is not functioning properly.

Contact technical support at ACI.

3.) Y2 will drive the actuator down 105% of selected range (200% on Version 2, 105% up on Ver 7) if

power is removed and reapplied. This is to assure the device being controlled is at 0% when

command voltage is applied. Output will return to commanded position after this calibration

process.

TESTING THE OUTPUT

Note: Output is contact closure only.

Placing J4 or J5 in the H position will close the corresponding contacts or the output. Never place both at

the same time. Conrm the resistance operation of meter and connect meter only to the corresponding

output terminal. “G” terminal is common for both. Resistance can be measured now. A “dead” or “near

dead” short should be measured when the output has been placed in the “H” position. Conrm the

appropriate LED it lit. Contact tech support if the output is not functioning.

TEST PROCEDURE (Version 1, 2, 3, 5, 6, 7 & 8)

Set the input jumpers to the required input signal settings. Set all the output switches to OFF. Place jumper

J6 CD/CE in the center position or remove (do not discard or lose jumper). With power and input only

connected, ramp input signal from 0 to 100% or in steps of 20%. Y2 will turn on from 25 – 49% of set range.

Y1 will turn on and Y2 will turn o from 50 – 73% of set range. Both relays will be on at 74% or greater. This

test conrms the unit is functional and operating correctly. Reset timing switches to desired range and J6

to the CD position. Reconnect input and output connections and retry application. Contact tech support

if application problems still exist.

TEST PROCEDURE (Version 4 ONLY)

Set the input jumpers to the required input signal settings. Set all the output switches to OFF. Place jumper

J6 CD/CE in the center position or remove (do not discard or lose jumper). With power and input only

connected, ramp input signal from 0 to 100% or in steps of 20%. Both relays will be on at 0-25%.Y1 will turn

on from 25 – 49% of set range. Y2 will turn on and Y1 will turn o from 50 – 73% of set range. Both relays

will be o at 74% or greater. This test conrms the unit is functional and operating correctly. Reset timing

switches to desired range and J6 to the CD position. Reconnect input and output connections and retry

application. Contact tech support if application problems still exist.

INPUT SIGNAL JUMPERS

Refer to the input signal range and oset jumper settings shown in the diagram on page 1.

Voltage Input

Connect the “+” or positive wire to the “UP/A+” terminal. Connect the common to the “24V-“ terminal.

Apply a voltage from control source. Measure the voltage at the input terminals. If the commanded

voltage is not present, remove the“+”or positive wire and measure from + wire to the“24V-“ terminal. If no

voltage is measured, check wiring from controller. If voltage disappears or is reduced when connected to

the AFP. Conrm input jumper is set to voltage mode and remove input wires. Remove power from unit

and measure the resistance from “Vout+” to “24V-“ terminals. Resistance in the voltage modes will be

around 10K Ohms and greater. If input is shorted contact tech support at ACI. If not shorted remove the

controller input common and connect power only to AFP. NOTE: Place meter in voltage mode and

measure VAC and VDC from analog input common wire to power supply common. If any voltage is

measured in DC or AC, a ground loop most likely exists. Use a separate 24V transformer for the AFP and let

common oat.

Current Input

Conrm the input jumper is in the 20mA mode. Measured input resistance is around 250 Ohms. Connect

“+” or positive wire to “UP/A+”and input “-“ or common to“24V-“. Apply mA signal. Place meter in voltage

and measure voltage across“UP/A+” and “24V-“. 4mA is equal to 1 volt and 20mA is equal to 5 volts. Use

Ohms Law to nd voltage from current. Current x 250 Ohms = Volts.

Example: 12mA (or 0.012) x 250 Ohms = 3 Volts. If no voltage is present, check wiring for open. Current

cannot exist without voltage present unless the input is dead shorted. If problem still persist see the“Note”

in voltage section.
