Troubleshooting

Turn on the input devices (DVD players, Blu-ray players, PCs, and other sources), output devices (display
screens, projectors), the control processor, and the PC and touchpanel or eBUS button panels. Touch a
configured button on the touchpanel or eBUS button panel.
If an input or output AV device cannot be remotely controlled (does not respond as expected), check the following:
•

Power Connections and Circuit Breaker

•
Ensure that all devices are plugged in.
•
Make sure that each device is receiving power. The IPL EXP front panel power LED lights if the unit is
receiving power.
•
For the AC power output ports on the IPL EXP PDU4H, verify that the unit is not in the overload state and the
circuit breaker has not been tripped. View the red Breaker LED on the front panel. If it is lit the breaker has
been tripped. The unit reports the state as
GC software or the IPL EXP PDU4H embedded web page show the current as zero, the breaker has been
tripped. To restore these ports to normal function, do the following:
1. Correct the hardware cause of the overload. Disconnect all of the devices from the IPL EXP PDU4H
power output ports.
2. Press the circuit breaker button to reset the circuit breaker. The unit waits a moment and rechecks the
ports.
NOTE: AC output power remains off after the circuit breaker is reset, unless the Manual Control
contact closure port is closed (On).
3. If the total (aggregate) current is within safe limits, connect the devices to the IPL EXP PDU4H and turn
them on (either one-by-one or all of them at once).
•
If current levels are safe, the unit continues normal operation. The current reading in Global
Configurator or the embedded web page changes from
drawn from the outputs.
•
If the aggregate current is outside safe limits (it exceeds the maximum threshold), the circuit breaker
trips again, and the AC output ports remain off until the breaker is reset and the overload is removed.
a. Repeat step 1 (disconnect all devices from the power ports) and step 2 (reset the circuit breaker).
b. Connect devices one at a time, allowing the IPL EXP to check current levels between each
