VOLTPAQ-X2 AND -X4 User Manual v 1.0

4 FUSE INSTALLATION
The VoltPAQ-X2 has two 3.0A fuses and the VoltPAQ-X4 has four 3.0A fuses. The fuses protect the amplifier from
over-current through the main power connector. The recommended fuse for this unit is the Cooper Bussmann MDL-
3-R, which is rated for 3A and 250V.
Caution: Make sure the power to the amplifier is disconnected before changing any fuses!
Follow this procedure to install or replace the fuses in the VoltPAQ-X2 and -X4:
1. The fuse holders are located at the rear of the unit, as shown in Figure 2.1.
2. Make sure the amplifier power cable is disconnected.
3. Remove the fuse holder. There are three fuses in the VoltPAQ-X2 and five in the VoltPAQ-X4. To do this, push
and twist the knob counter-clockwise and pull the fuse holder out as illustrated in Figure 4.1.
Figure 4.1: Remove fuse holders (VoltPAQ-X4 shown)
4. As shown in Figure 4.2, remove the old fuses from the holders and insert the new ones.
Figure 4.2: Replacing fuse in the fuse holder
5. Install the fuse holders back into the amplifier. Make sure the fuse being installed corresponds to the label at
the back of the amplifier, i.e., 3.0A (labels shown in Figure 4.1). Push the fuse holder back into panel and twist
the knob clockwise until secure.
Caution: Installing the wrong fuse rating may result in damage to your amplifier.
6. Connect the power cable to the back of the amplifier.

5 CABLE NOMENCLATURE
Table 5.1 provides a description of the standard cables used in the wiring of the VoltPAQ-X2 and -X4.
Cable Type Description
(a) Motor Cable
4-pin DIN to 6-pin
DIN motor cable
This cable connects the amplifier to the load. To apply
the amplified signal to the actuator, connect this cable
from the To Load socket on the amplifier to the system
actuator.
(b) 2xRCA to 2xRCA cable
2xRCA to 2xRCA
cable
This cable is used to connect the amplifier to the data
acquisition (DAQ) device. To apply the reference sig-
nal to the amplifier, connect an analog output channel
on the DAQ device to the Amplifier Command socket
on the amplifier. To measure the current or an analog
sensor, connect an analog input channel on the DAQ
device to the Current Sense or the S1,S2,S3, or S4
sockets on the amplifier.
(c) Analog Cable
6-pin mini-DIN to 6-
pin mini-DIN cable
This cable is used to connect an analog sensor on a
system (e.g., potentiometer, tachometer) to the ampli-
fier, where the signals can be either monitored and/or
used by a controller. The cable also carries a 12VDC
line from the amplifier to power a sensor and/or signal
conditioning circuitry.
(d) Emergency Stop Switch
Emergency Stop
(E-Stop) Switch
[optional]
Enables/disables the amplifier. Connect the Emer-
gency Stop Switch to the E-Stop connector on the
VoltPAQ-X2 and -X4. The amplifier is deactivated when
the knob is in the pressed DOWN position. It is enabled
when the knob is in the upright, released position. If the
E-Stop cable is not connected, the amplifier is always
enabled.
Important: The E-Stop is optional and not typically
supplied with the VoltPAQ-X2 and -X4.

6 TROUBLESHOOTING
Follow the steps given below based on your issue with the VoltPAQ-X2 and -X4.
Amplifier does not power up.
• Make sure the power cable is firmly connected to the power connector on the back of the VoltPAQ-X2 and -X4.
• Verify that the fuse is not burnt. If the fuse is burnt refer to Section 4.
Load not being driven.
• If the Emergency stop switch (optionally purchased through Quanser) is connected to the amplifier, make sure
the red button is in the upper position to enable the amplifier. The amplifier cannot be enabled when the button
is in the lower position. Twist the button to ensure it is in the enabled position.
• Verify that the fuses are not burnt.
• Make sure, for the particular channel you are using on the amplifier, that the connections have been made
correctly, i.e., the Amplifier Command socket on the amplifier is connected to the analog output channel on
your data acquisition device and the To Load socket on the amplifier is connected to the load. If you are using
a Quanser system, refer to the User Manual for that Quanser product for connection details.
Amplifier Enabled LED is red.
• If the Emergency stop switch (optionally purchased through Quanser) is connected to the amplifier, make sure
the red button is in the upper position to enable the amplifier. The amplifier cannot be enabled when the button
is in the lower position. Twist the button to ensure it is in the enabled position.
• Verify that the fuses are not burnt.
• The amplifier might be in thermal shutdown. Power down the amplifier and let it rest for 5 minutes. Verify all
the connections of the experiment and ensure that the load is not damaged.
No analog readings from the amplifier.
• Ensure the 5-pin mini-DIN analog cable is firmly connected from the amplifier socket (e.g., S1&S2 connector)
to the sensor on your device (e.g., tachometer).
• Confirm that the Analog Sensors RCA connector on the amplifier is connected to the correct analog input
channel on the data acquisition (DAQ) device.
• Check that the fuses are not burnt.
• Ensure the analog input channels on your data acquisition (DAQ) device are working. Refer to your DAQ User
Manual for information on how to test it.
• If the sensor is working, then one of the S1&S2,S3, or S4 Analog Sensors connectors may be defective. Try
using a different Analog Sensor input.
