Troubleshooting
Symptom:
■ There is no output laser beam; all LED status indicators are Off.
Possible Causes:
■ No DC voltage is applied.
Ensure that DC power cable connections are tight and verify that 30 VDC (t60/t100) or 36 VDC (t80) is
applied to the RF power supply under full load.
Laser replacement
Symptom:
■ When connecting a newer t60 Laser Head to an older RF-600 RF power supply (or vice versa) for
troubleshooting purposes, the Interconnect cable will not attach.
Possible Causes:
■
On newer t60 Laser Heads, the RF Supply connector is a male DB-9 connector; older t60 models
used a female RF Supply DB-9 connector.
Caution
possible
equipment
damage
Do not connect or disconnect the Interconnect cable while DC power
is applied to the RF power supply. This may damage the RF supply’s
internal circuitry. Always remove DC power before connecting or
disconnecting cables from the laser or RF power supply.
Although we recommend keeping t-Series Laser Heads and RF power supplies together as matched sets, in
some cases it is useful to swap components for troubleshooting purposes. In situations where the Intercon-
nect cable does not match the RF Supply connector on the Laser Head, it is permissible to attach a male/
female gender-changing connector between the Interconnect cable and the Laser Head.
