4 FUSE INSTALLATION
The VoltPAQ-X1 has two 3.0A fuses that protect the amplifier from overcurrent 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-X1:
1. The fuse holders are located at the rear of the unit, as shown in Figure 4.1.
Figure 4.1: VoltPAQ-X1 fuse holders
2. Make sure the amplifier power cable is disconnected.
3. Remove both fuse holders. To do this, push and twist the knob counter-clockwise and pull the fuse holder out
as illustrated in Figure 4.2.
Figure 4.2: Remove fuse holders
4. As shown in Figure 4.3, remove the old fuses from the holders and insert the new ones.
Figure 4.3: Replacing fuse in the fuse holder
VOLTPAQ-X1 User Manual v 1.1

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 4.2). 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-x1.
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 from
the "To Load" socket on the VoltPAQ-X1 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 signal
to the amplifier, connect an analog output channel on
the DAQ device to the "Amplifier Command" socket on
the VoltPAQ-X1. To measure the current in the load,
connect an analog input channel on the DAQ device to
the "Current Sense" socket on the VoltPAQ-X1.
(c) 5-pin-DIN to 4xRCA cable
5-pin-DIN to
4xRCA cable
This cable connects the analog signals that are con-
nected to the amplifier, i.e. sensors, to a data acqui-
sition (DAQ) device. Connect the 5-pin-DIN side of the
cable to the "To ADC" socket on the VoltPAQ-X1 and the
RCA cables to the analog input channels on your data
acquisition (DAQ) device. The yellow and white RCA
cables carry the signals connected to the "S1&S2" con-
nector. The red RCA carries the "S3" signal and the
black RCA carries the "S4" signal.
(d) 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.
(e) 16-pin ribbon cable
Emergency Stop
Switch (E-Stop)
Enables/disables the amplifier. Connect this cable to
the VoltPAQ-X1 E-Stop socket. The amplifier is deacti-
vated 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 am-
plifier is always enabled.
Important: The E-Stop cable is optional and not typi-
cally supplied with the VoltPAQ-X1.

6 TROUBLESHOOTING
Follow the steps given below based on your issue with the VoltPAQ-X1.
Amplifier does not power up.
• Make sure the power cable is firmly connected to the power connector on the back of the VoltPAQ.
• 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 both 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.
LED does not light up.
• 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 both 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-DIN to 4xRCA cable is firmly connected from the To ADC socket on the VoltPAQ-X1 to analog
input channels on the DAQ device.
• Make sure the analog input channel you are attempting to read matches how the connections are made. For
example, if your sensor is connected to the S3 socket on the VoltPAQ-X1, then the signal is available on the
red RCA cable. Verify that the red RCA is connected to the analog input channel you are attempting to read
• 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 the Analog Sensor Input connector S1&S2,S3, or S4 socket may be defective.
Try using a different Analog Sensor Input.
