NOTE
The remote monitoring samples in 2.2.15.2
through 2.2.15.8 are op-amp buffered
outputs from an analog-to-digital converter
(ADC). The dc voltage of each output
sample varies linearly with the parameter
being monitored.
The maximum sample voltage is
representative of the parameter’s full-scale
value (e.g., 12,000 W for V10 forward
power; 9,000 W for V7.5 forward power;
6,000 W for V5 forward power; 4,500 W for
V3.5 forward power). This full-scale voltage
can be scaled (between 0 and 5 V), using
the front panel’s GUI, to suit a particular
requirement. Each monitoring circuit’s
impedance must be greater than 1,000
Ω
.
There are also five user-configurable sample
outputs (Sample Out 8 through Sample Out
12), which can be used to monitor any
metered parameter on the GUI (see 3.6.11).
2.2.15.2 Forward Power Level Sample
(Sample Out 1)
The dc voltage on TB1-20 is full-scale when
the forward power is 12,000 W (V10),
9,000 W (V7.5), 6,000 W (V5) or 4,500 W
(V3.5).
2.2.15.3 Reflected Power Level Sample
(Sample Out 2)
The dc voltage on TB1-21 is full-scale when
the reflected power is 1,200 W (V10), 900 W
(V7.5), 600 W (V5) or 450 W (V3.5).
2.2.15.4 Power Amplifier Volts Sample
(Sample Out 3)
The dc voltage on J6-9 is full-scale when the
PA voltage is 60 V.
2.2.15.5 Exciter Forward Power Level
Sample
(Sample Out 4)
The dc voltage on J6-10 is full-scale when
the exciter forward power is 50 W.
2.2.15.6 Intake Air Temperature Sample
(Sample Out 5)
The dc voltage on J6-11 is full-scale when
the intake air temperature is 90°C.
2.2.15.7 Exhaust Air Temperature Sample
(Sample Out 6)
The dc voltage on J6-12 is full-scale when
the exhaust air temperature is 90°C.
2.2.15.8 Total PA Current Sample
(Sample Out 7)
The dc voltage on J6-21 is full-scale when
the total power amplifier current is 360 A
(V10), 270 A (V7.5), 180 A (V5) or 135 A
(V3.5).
2.2.16 Remote Alarm Indications
Outputs are available on the remote
interface PWB (A44) [see Table 2-4 or
Figure 2-7a (V10/V7.5) or 2-7b (V5/V3.5) for
pin assignment] that indicate when stress
thresholds for critical parameters are
exceeded. A switching device for each alarm
output provides a current-sink-to-ground
when an alarm occurs. The switching circuit
provides an open collector during normal
operation and has no influence on the
external monitoring circuit. Each circuit must
present impedance between the switching
device and a dc voltage source that limits
current to 50 mA.
+15V is available at
TB1-18 of the remote interface PWB. If an
external dc power source is used, it must not
24 V. Its return must be connected
to a
GND terminal [see Figure 2-7a
(V10/V7.5) or 2-7b (V5/V3.5)] on the remote
interface PWB. Unless otherwise noted, all
remote interfacing is made to the remote
interface PWB.
2.2.16.1 Summary Alarm
An alarm output that indicates any alarm is
occurring is available on TB1-4 (
SMY
ALARM ).
2.2.16.2 Battery/Memory Fail Alarm
An alarm output that indicates the battery for
the controller memory is below a safe
operating threshold or that the checksum for
the controller EEPROM is incorrect is
available on TB1-6 (
BATT/MEM FAIL
ALARM ).
