Installation and Setup

Precautions

WARNING! All wiring must be performed by a qualified electri-

cian or instrumentation engineer. See diagram for terminal

designations and wiring examples. Consult factory for assis-

tance.

WARNING! Avoid shock hazards! Turn signal input, output, and

power off before connecting or disconnecting wiring, or remov-

ing or installing module.

Précautions

ATTENTION! Tout le câblage doit être effectué par un élec-

tricien ou ingénieur en instrumentation qualifié. Voir le dia-

gramme pour désignations des bornes et des exemples de

câblage. Consulter l'usine pour assistance.

ATTENTION! Éviter les risques de choc! Fermez le signal

d'entrée, le signal de sortie et l'alimentation électrique avant

de connecter ou de déconnecter le câblage, ou de retirer ou

d'installer le module.

API maintains a constant effort to upgrade and improve its products.

Specifications are subject to change without notice. See api-usa.com for

latest product information. Consult factory for your specific requirements.

WARNING: This product can expose you to chemicals includ-

ing nickel, which are known to the State of California to cause

cancer or birth defects or other reproductive harm. For more

Electrical Connections

Polarity must be observed for output wiring connections. If the

output does not function, check wiring and polarity.

See wiring diagrams at right. Observe polarity. If the output

does not function, check wiring and polarity.

Do not make any connections to unused terminals or use

them as wiring junctions for external devices. This may cause

permanent damage to the module!

Each product is factory configured to your exact input and

output ranges as indicated on the serial number label.

Input

For an AC signal is it not necessary to observe polarity when

connecting the input.

Connect the AC signal input to terminals 9 and 11 as shown in

the wiring diagram.

Type of Input Device

Terminal

Device with an AC voltage or

AC milliamp output.

Voltage Output

If your receiving device (such as a PLC or a display) uses a

voltage input, use terminals 3 and 4 as shown in the wiring

diagram.

Current Output

Determine if your receiving device (such as a PLC or a display)

provides power to the current loop or if the loop must be pow-

ered by the APD module. Typical voltage may be 9-24 VDC at

your device's input terminals if it provides power to the loop.

If your device does not power the current loop, the APD can

provide power using terminals 3 and 4 as shown as shown in

the wiring diagram.

If it provides power to the loop or an external supply provides

power to the loop, use terminals 2 and 3 as shown as shown

in the wiring diagram.

Type of Device for Output

– Terminal

Measuring/recording device

Measuring/recording device

accepts a mA (current) input

passive. APD module provides

the loop power.

Measuring/recording device

accepts a mA (current) input

2 (–)

and provides power to the

current loop.

Module Power

Check model/serial number label for module operating voltage

to make sure it matches available power.

When using DC power, either polarity is acceptable, but for

consistency with similar API products, positive (+) can be wired

to terminal 13 and negative (–) can be wired to terminal 16.

The power supplies are fuse protected and the unit may be

returned to API for fuse replacement.

Mounting to a DIN Rail

Install module vertically on a 35 mm DIN rail in a protective

enclosure away from heat sources. Do not block air flow. Allow

1" (25 mm) above and below housing

vents for air circulation.

1. Tilt front of module downward and posi-

tion against DIN rail.

2. Clip lower mount to bottom edge of

DIN rail.

3. Push front of module upward until

upper mount snaps into place.

Removal

1. Push up on the bottom back of the

module.

2. Tilt front of module downward

to release upper mount from top

edge of DIN rail.

3. The module can now be removed from

the DIN rail.

Calibration

Input and output ranges are factory pre-

configured (at 24°C ±1°C). Front-mounted Zero and Span

potentiometers are used to calibrate the output to compensate

for load and lead variations.

1. Apply power to the module and allow a minimum 20 minute

warm up time.

2. Using an accurate calibration source, provide an input to

the module equal to the minimum input required for the

application.

3. Using an accurate measurement device for the output,

adjust the Zero potentiometer for the exact minimum output

desired. The Zero control should only be adjusted when the

input signal is at its minimum. This will produce the cor-

responding minimum output signal. For example: 4 mA for

a 4-20 mA output or –10 V for a ±10V output.

4. Set the input at maximum and adjust the Span pot for the

exact maximum output desired. The Span control should

only be adjusted when the input signal is at its maximum.

Terminal

This will produce the corresponding maximum output

signal. Example: for 4-20 mA output, the Span control will

provide adjustment for the 20 mA or high end of the signal.

5. Repeat adjustments for maximum accuracy.

Output Test Function

When the Test button is depressed it will drive the output with a

known good signal that can be used as a diagnostic aid during

initial start-up or troubleshooting. When released, the output

will return to normal.

The Test Cal. potentiometer is factory set to approximately

50% output. It can be adjusted to set the test output from 0 to

100% of the output span. Press and hold the Test button and

adjust the Test Cal. potentiometer for the desired output level.

Operation

The APD 6010 accepts an AC voltage or current input and

provides an optically isolated DC voltage or current output that

is linearly related to the input.

The green LoopTracker

that a signal is being sensed by the input circuitry of the mod-

+ Terminal

ule. It also indicates the input signal strength by changing in

intensity as the process changes from minimum to maximum.

(+)

If the LED fails to illuminate, or fails to change in intensity as

the process changes, check the module power or signal input

wiring. Note that it may be difficult to see the LEDs under bright

(+20 V)

lighting conditions.

The red LoopTracker output LED provides a visual indication

that the output signal is functioning. It becomes brighter as

the input and the corresponding output change from minimum

to maximum.

(+)

For current outputs, the red LED will only light if the output loop

current path is complete. For either current or voltage outputs,

failure to illuminate or a failure to change in intensity as the

process changes may indicate a problem with the module

power or signal output wiring.
