Description
1. Handle
The SunRay handle can be used to carry the lamp housing
assembly, or to raise or lower the unit height.
WARNING:
The handle should never be used to lift or carry
the SunRay unit when it is mounted to a stand or other
supporting device.
2. Lamp Hour Meter
The lamp hour meter is used to track the age of the arc
lamp. The meter reading should be recorded when the lamp
is replaced. Optionally, the reading can be zeroed via the
hour reset signal on the rear panel DSUB connector when
the lamp is replaced (see section 7 for signal interface info).
3. Lamp Power Select Switch
The Lamp Power rocker switch se
lects either the “full” or
“standby” lamp power setting. When curing or warming-up
the lamp, the switch should be set to full power. Between
curing operations, the switch can be set to the standby
setting, which reduces the amount of heat and stray UV light
radiated by the unit. When switching back to full power, the
lamp will be ready for curing again after a brief 10 second
re-warming period.
4. Lamp Access Panel
The Lamp Access Panel can be removed for inspection or
replacement of the arc lamp.
WARNING:
High voltages and high temperatures are
accessible with this panel removed. Always switch the Input
Power Switch off, disconnect the input power cord, and wait
for the unit to cool before removing this panel.
5. DSUB Interface Connector
Signal interface for SunRay external control (see section 7).
6. Input Power Switch &
Receptacle
The Input Power switch is used to apply or remove main
power to the SunRay system. Co-located with the switch is
the IEC type power cord socket where the input line cord is
inserted.
7. Cooling Fan w/
removable filter
The system cooling fan has a foam filter element that can be
removed for periodic cleaning (as required).
8. Height Adjustment Knob
When used with the optional Flood Stand, the rear mounted
Height Adjustment Knob is used to set the optimum distance
from the lamp to the substrate being cured.
