g.
Check the addresses and jumpers on all system cards and units. I t is advisable to make
a list of each of the system addresses for future reference. Refer to the individual unit
manuals if it is necessary to change addresses or jumpers.
h. Install all cards in the 10740A Coupler (see Figure 5-5). Be certain that the 10760A
Counter cards are in the proper order.
i. Connect the reference/measurernent cable from the laser head and first receiver to
the first 10760A Counter card (see Figure 5-7 for a typical system setup).
j.
Connect the hooded connectors in sequence to each of the additional 10760A Counters
in the system and daisy-chain the REF connectors a s shown in Figure 5-7.
k. If the standard 10756A Manual Compensator is used, mount it on the edge connector
of the 10755A Compensation Interface.
I. Apply system power and verify that the reference and measurement LED indicators
located near the bottom front edge of each counter light (the reference LED indicator
i s the one closest to the front edge). Remove system power.
m. Connect the system controller to the 10746A Binary Interface using the cable fabricated
during the preliminary procedure.
n.
If 10783A Numeric Displays are used, connect them to the system controller using the
10631A, B, or C cables. Refer to the 10783A Numeric Display Operating and Service
manual.
o. Apply system power. At the rear panel of the 10740A Coupler, verify that the voltage i s
+I5 +0.25V dc, -15 +0.25V dc, and +5 +0.10, -0.05V dc (see Figure 5-4).
5.9 Comparator-Based System Installation
Perform the installation of the comparator-based system a s follows:
a.
If the 10740A Coupler i s to be rack mounted or installed in a cabinet, refer to the
10740A Coupler Operating and Service manual for dimensions and installation
instructions.
b. Connect the +5V power supply cable between the power supply and the 10740A
Coupler rear panel terminal strip.
c. Connect the k15V power supply cable between the power supply and the 10740A
Coupler rear-panel terminal strip. Note that if the optional 5510A Opt. 010 Automatic
Compensator is used, connect the interface cable between the 5510A Opt. 010 and the
10755A Compensation Interface.
d.
if the 10783A Numeric Displays are used, connect the +5V power cables between the
numeric display rear panels and the +5V power source on the back of the 10740A
Coupler.
e. Connect the +15V power supply and +5V to suitable sources of ac power. Apply system
power. Verify the voltage at the coupler rear panel is +15V dc k0.25, -15V dc f 0.25,
and +5V dc +0.10, -0.05. For 4-axis 10746A systems, the voltage on the front of the left-
most card (output card of the recommended configuration) should be set to 4.8 t o 4.9
volts. Remove system power.
NOTE
To connect any hooded connector to a circuit card in the
10740A Coupler, pass the connector through the slot in the rear
panel of the coupler and install it on the front edge connector
of the applicable card (see Figure 5-5).
