External
Alarm
The External Alarm Beacon is used to indicate system ready and
wax low situations. The beacon is comprised of a green light and a
red light. When the CPU detects an wax low condition, it will cause
the red light to flash. When the green light is lit, the system is ready
for printing. The lenses on the lights are made of heat and shock
resistant polycarbonate resin. The can be mounted onto of the floor
stand or integrated into a conveyor system.
Line Speed
Monitoring
(Shaft
Encoder)
Shaft encoders are timing instruments necessary for applications
with varying conveyor line speed and/or for printing bar codes. The
shaft encoder synchronizes Printhead firing to the speed of the
production line. Shaft encoders generate a number of pulses during
shaft rotation that relate to the conveyor line travel. Typically, shaft
encoders are comprised of a wheel attached to the shaft of an encoder
module. The size of the wheel and the number of pulse per
revolution that the encoder outputs and the rate of rotation will
determine the frequency at which the Printhead will fire.
FoxJet’s Shaft Encoder Kit is comprised of 3 wheels and a 5000 PER
shaft encoder mounted in a spring loaded pivot bracket that can be
used to generate a pulse train that provides 245, 284 and 300 base
DPI. Base DPI’s can be further adjusted during programming. (See
WIDTH command in the Command Definitions.)
