Mark V ProVis Injection System
15 - 4
Test Point / Description Typical Values
10 BMSPOSCMD Measure the same as test point 6
Buffered M/S Position CMD when the Mechanical Stop is not
moving.
11 10V REF. +10.0 +0.1 VDC.
+10 VDC Reference
12 DIG. VELOCITY +0.1 VDC/ml (+4.0 VDC at 40 ml/sec).
Digital Velocity
13 ANA. VELOCITY +0.15 V/ml (+6.0 VDC at 40 ml/sec).
Analog Velocity
14 SAFRELO
+24 VDC when disarmed and not
Safe Relay Low loading; less than +2 VDC when
armed, injecting, or loading.
15 INJ. START +5 VDC when start switch open; 0 to
Inject Start +0.1 VDC when start switch closed.
16 INJECTING Zero during standby; +5 VDC when
Injecting injecting; immediately returns to zero
at injection end - no delay.
17 INJECT Zero during standby; +15 VDC when
Inject injecting; should stay at +15 VDC for
two seconds after the end of the
injection, then return to zero. With
ECG injections, stays high for one
second at end of injection.
18 A.G. Reference for other test point grounds.
Analog Ground
19 +15V +15 +/- 0.5 VDC.
20 -15V -15 +/- 0.5 VDC.
21 +5V +5 +/- 0.25 VDC
.
22 MVOLTS
Injecting, 0 - +90 VDC, depending on
Motor Volts speed. During forward load, typically
measures 7-15 VDC. Reverse load -
less than 0 VDC.
