Precautions
WARNING! All wiring must be performed by a qualified electrician
or instrumentation engineer. See diagram for terminal designa-
tions and wiring examples. Consult factory for assistance.
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.
Electrical Connections
See wiring diagrams at right. Polarity must be observed when
connecting the signal input or feedback.
*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!
See the model/serial number label for module information,
power requirements, options, or if a custom version was speci-
fied. Input and feedback ranges are factory pre-configured (at
24°C ±1°C).
Control Input
The input range is factory configured. See the model/serial
number label for input type, range, and options.
See diagrams for terminal designations and wiring examples.
If a 4-20 mA control input is specified the module does not
provide power to the loop. The 4-20 mA signal must be from a
powered transmitter or a loop with a power supply.
Potentiometer (Slidewire) Feedback Signal
See diagrams for terminal designations and wiring examples.
Voltage (M01) or mA (M420) Feedback Signal
See diagrams for terminal designations and wiring examples.
Polarity must be observed.
The APD 3200 M420 uses a 4-20 mA feedback signal. The
module does not provide power to the loop, thus the feedback
signal must be from a powered transmitter or a loop with a
power supply.
Relay Output Terminals
See diagrams for terminal designations and wiring examples.
Module Power Terminals
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.
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 position 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
For most applications the deadband is the only required adjustment.
1. Deadband is normally adjusted after installation is complete.
2. Turn the deadband potentiometer counterclockwise to minimum.
3. Provide a near mid-level control input signal.
4. Allow the valve to stabilize.
5. If overshoot, oscillation, or hunting are detected, slowly
increase the deadband clockwise to eliminate the oscillation.
Input zero and span normally do not need to be adjusted.
1. If adjustment is required, apply a control input that repre-
sents the fully closed position.
2. Adjust the zero control to just close the valve.
3. Apply a full open control input signal.
4. Adjust the span control to just fully open the valve.
Operation
The APD 3200 provides an excitation voltage to the feedback
potentiometer on the valve or valve actuator and monitors
its position. If the difference between the control signal and
the feedback signal is greater than the deadband setting, the
appropriate relay is energized to actuate the positioning motor.
The APD 3200 M01 has a voltage feedback signal and control
signal input (unless another voltage range was specified). The
difference between the control signal input and the feedback
signal is compared to the deadband setting. If the difference
between the two is greater than the deadband setting, the appro-
priate relay contact is energized to actuate the positioning motor.
The APD 3200 M420 uses a 4-20 mA control signal input and
feedback signal (unless another current range was specified).
The difference between the control signal input and the feedback
signal is compared to the deadband setting. If the difference
between the two is greater than the deadband setting, the appro-
priate relay contact is energized to actuate the positioning motor.
The LoopTracker®input LED provides a visual indication that
a signal is being sensed by the input circuitry of the module. It
also indicates the input signal strength by changing in intensity
as the process changes from minimum to maximum to provide
a quick visual picture of your process loop at all times.
If the LED fails to illuminate, or fails to change in intensity as
the process changes, this may indicate a problem with module
power or signal input wiring. This features greatly aid in saving
time during initial start-up or troubleshooting.
Control Relays
For all versions an electronic lockout circuit is used to prevent
both relay contacts from closing simultaneously. When the
input and the feedback signals are equal, the relay contacts
will go to the neutral position.
The bi-color relay LED provides a visual indication of the relay
status. In all configurations, a green LED indicates a valve open
relay position and a red LED indicates a valve closed relay posi-
tion. In the neutral position, the LED will be off.
Manual/Auto Mode
Switching the top-mounted toggle switch to Manual allows the
Open and Close push buttons to be used to position the valve
independent of the control and feedback signals. The manual
mode is useful for troubleshooting, calibration, system testing,
or as a manual bypass. The bi-color relay LED indicates the
controller’s Open/Close relay contact status. Switching to Auto
mode allows normal operation.
