Troubleshooting
Troubleshooting tips:
Be sure to check all power and control connections to the actuator and ensure connectors are properly attached and fully
seated.
Note that the Intelli-Motion Configurator software displays information about the digital and analog input signals on the
iSPA actuator, which may be helpful in troubleshooting common problems with an installation.
For further tips and guidance, see below.
Problem
Possible Cause
Solution
No motion when actuator
commanded to extend or retract.
Main power supply missing.
Check power supply to the actuator, including
connections and fusing.
Power supply voltage too low.
Verify that the supply voltage is in tolerance, and
that it does not sag when operating the actuator
(due to high impedance in the supply path).
Power supply voltage too high.
Disconnect supply voltage and connect to a supply
within the proper tolerance.
Note: High supply voltage may damage the actuator
electronics.
Actuator travel stops prematurely. Extend and Retract limits not set properly.
(Base and Analog models)
Follow instructions to set Extend and Retract limits
using the pushbuttons on the User I/O board or
using the Configurator software.
Extend and Retract limits not set properly.
(Ethernet model)
Travel limits are set in the cyclical control Ethernet
message. Ensure these are configured properly in
your PLC program.
Actuator does not respond to
Extend and Retract control
signals. (Base model)
Control cable is damaged.
Inspect cable for possible damage including cuts or
pinching.
Control signals not wired correctly, or
ground missing.
Ensure all control wiring is consistent with
instructions in the user manual.
Control signal does not meet electrical
specifications.
Control signals should be 24VDC nominal, with 8mA
capacity.
Extend and Retract commanded
simultaneously.
Actuator will not move if both directional signals are
present.
Actuator position does not match
analog input reference. (Analog
model)
Control cable is damaged.
Inspect cable for possible damage including cuts or
pinching.
Control signals not wired correctly, or
ground missing.
Ensure all control wiring is consistent with
instructions in the user manual.
Verify that the Analog Input and Analog Output are
not cross-wired.
Input signal configured incorrectly.
Ensure that the configuration (DIP) switch settings
match your signal type (0-10V or 4-20mA).
Actuator is not enabled.
Ensure that the Enable signal is turned on after
selecting a position reference with the Analog Input.
