Maintenance
The PSE235 Remote Strobe Power Supply has been designed to provide trouble free service. In case of
difficulty, refer to the troubleshooting section. Periodic inspection of power supply wiring, and strobe light
head connections for shorted or open wires will assure trouble free operation. The primary cause of short
circuits has been found to be wires passing through firewalls, roofs, etc.
Troubleshooting
All PSE235 Remote Strobe Power Supply units are thoroughly tested before shipment. However, should you
encounter a problem during installation or during the life of the product, refer to the guide below for
information on troubleshooting. In most cases problems that occur will be related either to the power/control

return the unit to the factory for service. Additional information may be obtained from the factory technical
