DESCRIPTION
(Fig. 2-2)
BITE switch S5
10-position rotary switch. When SYSTEM SELECT switch is at
BITE, BITE switch provides simulated transducer signals and
selects voltages for measurement on DVM as follows:
-20V
-
Output of –20-volt dc power supply is selected for
display.
+20V - Output of +20-volt dc power supply is selected for
display.
-12V
-
Output of -12-volt dc power supply is selected for
display.
+12V
-
Output of +12-volt dc power supply is selected for
display.
+5V
-
Output of +5-volt dc power supply is selected for
display.
13V RMS - Output of 13-volt 400 Hz power supply is
selected for display.
SAS 1 SELF - Simulated transducer signal is applied to No.
1 self demodulators and No. 1 self voltage is indicated on
DVM.
SAS 1 CROSS - Simulated transducer signal is applied to
No. 1 cross demodulators and No. 1 cross voltage is indicated
on DVM.
SAS 2 SELF - Simulated transducer signal is applied to No.
2 self demodulators and No. 2 self voltage is indicated on
DVM.
SAS 2 CROSS - Simulated transducer signal is applied to
No. 2 cross demodulators and No. 2 cross voltage is indicated
on DVM.
NOTE
SAS 1 and SAS 2 sections of the test set panel have identical controls and
indicators. Only one set is described. Reference designations for SAS 1
components are given. Reference designations for SAS 2 components are
in parentheses.
FUNCTION SELECT
5-position rotary switch.
switch S16 (S14)
SQ WAVE
- Corresponding extensible link oscillates at 30
strokes per minute. Maximum length of stroke is controlled
by SQ WAVE control.
CLSD LOOP - Corresponding extensible link is manually
controlled by VALVE CONTROL.
HARDOVER RETRACT - Corresponding extensible link
goes to hardover retract.
BALANCE - Corresponding extensible link goes to null
position.
HARDOVER EXTEND
- Corresponding extensible link
goes to hardover extend.
