Installation and Setup APD 7010
Output 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. An accurate frequency calibration source such
as a signal generator may be required for calibration.
2. Provide an input to the module equal to the minimum input
required for the application. In the most cases the minimum
input signal will be 0 Hz.
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 corresponding minimum output
signal. Example: for 4-20 mA output signal, the Zero control will
provide adjustment for the 4 mA or low end of the signal.
4. Set the frequency to the maximum input required for the appli-
cation. This is generally done using a signal generator.
5. Using an accurate measurement device for the output, 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.
This will produce the corresponding maximum output signal.
Example: for 4-20 mA output signal, the Span control will provide
adjustment for the 20 mA or high end of the signal.
6. Repeat adjustments for maximum accuracy.
Sensitivity Adjustment
This multi-turn potentiometer provides an adjustable threshold
level that the incoming signal must overcome before an output can
be produced. This is used to limit noise and minimize false input
signals that may cause erroneous readings.
Fully clockwise: (max. sensitivity), input threshold is ±25 mV.
Fully counterclockwise: (min. sensitivity), input threshold is ±2.5 volts.
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 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 7010 accepts a frequency input and provides an optically
isolated DC voltage or current output that is linearly related to the
input. The frequency input can be virtually any type of signal (sine
wave, sawtooth, square wave, etc.) as long as there is a sufficient
change in amplitude (greater than 100 mV).
The frequency input to the APD 7010 is capacitively coupled (to remove
any DC component at the input) to a comparator whose threshold is
determined by the setting of the sensitivity control. The output from the
comparator passes through an optocoupler to the output stage.
The green LoopTracker®input LED provides a visual indication that
a signal is being sensed by the input circuitry of the module. The
LED illuminates when the input is sufficiently large to trigger the
input comparator depending on the input sensitivity adjustment.
It also indicates the input signal range by changing in intensity as
the frequency changes from minimum to maximum. If the LED fails
to illuminate, or change in intensity as the frequency changes, it may
indicate a problem with module power, or signal input wiring.
Note that it may be difficult to see the LEDs under bright 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 cur-
rent 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.
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 removing
or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un électricien
ou ingénieur en instrumentation qualifié. Voir le diagramme 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. 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!
Output
The output range is pre-configured at the factory as specified on your
order. Polarity must be observed when connecting the signal output
to the load. See the table below and the wiring diagrams at right.
The APD 7010 output can be wired to provide power to drive a
current loop. Determine if your receiving device provides power to
the current loop or if the loop must be powered by the APD module.
Use a multi-meter to check for voltage at your device's input termi-
nals. Typical voltage may be 9-24 VDC if it provides power to the loop.
Input
The input range is pre-configured at the factory as specified on your
order. No input calibration is necessary. The APD 7010 is compat-
ible with most types of sensors as long as the waveform produces
a minimum 100 mV amplitude change and a minimum 5 microsec-
ond pulse width. Always refer to the sensor manufacturer's data
sheet to determine supply voltage compatibility and proper wiring.
A 15 VDC supply is available to power the sensor if required.
Sensor Load
The signal input of the APD 7010 is capacitively coupled to prevent
any DC in the input. Some sensors, typically those without an
internal load resistor, require a resistive load in order to function.
The resistor value may be specified by the sensor manufacturer
as the "minimum resistive load" or calculated from the sensor
manufacturer's specified "load current range".
The 15 VDC power supply is capable of providing 25 mA. A load current
range of 3 mA to 25 mA would typically use a 5 kWto 500 Wresistor.
NPN sensors may require an external resistor across sensor signal
and sensor power. See sensor manufacturer's specifications.
PNP sensors may require an external resistor across sensor signal
and sensor ground. See sensor manufacturer's specifications.
Module Power
Check model/serial number label for module operating voltage to
make sure it matches available power. For DC power, either polar-
ity is acceptable, but for consistency, 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 enclo-
sure 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.
