1-23. DAYSIDE TEST BENCH 2A1 (cont)
(b) To return the filter to the start position (out of the optic path),
the OA FILTER 1 signal is removed, causing relay K1 to reenergize.
causes +28 vdc to be routed through contacts of switch S2 and relay K1 (B1,B2) to
filter motor M1.
The circuit is completed (in opposite direction) through another
set of relay K1 contacts (A1,A2), to ground, and the motor moves the filter out of
the optic path.
When the filter is fully out of the optic path, switch S2 contacts
are opened and the motor stops turning.
At this time, optical switch A3 transmits
an OA FILTER POS 2 signal to the multi programmer assembly.
b.1 ADAPTER PANEL ASSEMBLY 2A1A1 (EO BENCH SERIAL NUMBERS 00106 AND UP)
(1) The adapter panel assembly is an electrical interface that allows
connections from the IVD and power supplies to be available at its front panel.
(2) Signals applied to J11 on the side panel are routed to J2 and J3 on the
Signals applied to J3 and J17 on the side panel are routed to J8 and
J14, respectively, on the front panel.
c. INNER MODULE 2A1A2

the dayside bench electrical and optical assemblies. It contains the following
Optics assembly 2A1A2A1
Shutter assembly 2A1A2A2
Radiometer assembly 2A1A2A3
Dayside sensor mount assembly 2A1A2A4
Laser fold mirror assembly 2A1A2A6
Filter wheel/motor 2A1A2A1O
Lampholder assembly 2A1A2A11
Automatic focus control assembly 2A1A2A12
Beam sampler 2A1A2A13
Laser cover assembly 2A1A2A19
(2) Optics Assembly 2A1A2A1.
The optics assembly contains the following
Laser simulator assembly
CID video camera
(a) The laser simulator assembly provides low-level laser energy for test-
ing the sensitivity of the laser spot tracker and the laser range receiver UUTs. It
is operated in continuous or pulsed mode at a rate set by computer command.
(b) The laser simulator assembly consists of laser simulator A1, laser
detector A2, and power supply PS1.
