CAUTION
Do not continue with the procedure until the power supplies
voltages are within the limits specified in step
d.
Excessive
voltage can cause damage to system components.
d.
Connect
the
k15V
and
+5V
power
supplies
to
a
suitable
source
of
ac
power.
Verify
that
the
outputs
of the
k15V
power
supply
are
+15V
k0.25V
dc
and
-15V
k0.25V
dc.
Verify
that
the
output
of
the
+5-volt
power
supply
is
+5
$0.1,
-0.05V
dc.
If out
of
specification
and
the
HP
power
supplies
are
used,
refer
to
the
applicable
manual.
Remove
system
power.
NOTE
During cable installation, the machine system geometry may
require that the ends of the reference and measurement
cables fit through spaces too small for the cable connectors.
If so, check the laser head and receiver by connecting L15V
from the f15V power supply. O n the laser head, connect the
+15V to pin A, the -15V to pin B, and the return to pin D of the
POWER connector (Figure 4-7). O n the receiver(s) connect
the +15V to pin 4 and return to pin 3 (see Figure 4-6).
WARNING
BEFORE PERFORMING THE FOLLOWING STEPS, BE SURE
THAT ALL SYSTEM ITEMS THAT ARE CONNECTED T O A N
A C POWER SOURCE HAVE A C O M M O N EARTH GROUND
CONNECTION. IT IS POSSIBLE T O HAVE A DIFFERENCE I N
ELECTRICAL POTENTIAL BETWEEN THE VARIOUS SYSTEM
COMPONENTS IF A C O M M O N GROUND IS N O T ENSURED.
THIS CONDITION CAN CAUSE INJURY T O OPERATING
PERSONNEL AND/OR
CAUSE DAMAGE T O THE SYSTEM
COMPONENTS. ALSO, BE CERTAIN THAT ANY SURROUND-
I N G EQUIPMENT, SUCH AS A MACHINE TOOL, HAS THE
SAME C O M M O N GROUND FOR ITS POWER SOURCE AS THE
LASER SYSTEM GROUND.
e.
Connect the f15V power cable between the f15V power supply and the laser head
POWER connector. If you have fabricated your own cables and have any doubt which
cable is indicated, refer to Appendix C, CABLING.
NOTE
I n step
f
(except for the 10781A Pulse Converter System) it i s
not necessary to connect the electronic interface connectors
to their respective units (counter, fast pulse converter, etc). The
+15V lines of these connectors are replicated within the interface
connectors. For the 10781A Pulse Converter, the connector
must be connected since the +15V lines are replicated within
the pulse converter.
