INPUT IMPEDANCE:
With S1 and S3 “OFF”, the resistive input
impedance exceeds 1megohm as long as the
“SIG. IN”
(Terminal 5) input
voltage is between zero and +12 VDC. Beyond these levels, the high and low
clamping diode will start to conduct, thus decreasing the input impedance.
With S3 “ON” the maximum input voltage to Terminal 5 must be limited to
28 VDC.
9.
PARALLELING WITH APOLLO TOTALIZER (RLC standard count
input) INPUTS:
Apollo Rate Indicators may be parallel connected with
counters having the RLC standard count input circuitry. These can operate
from a common current sink or source sensor, by connecting the appropriate
terminals in common. S3 on the Rate Indicator should be turned
“OFF”
since pull-up or pull-down resistors are already present in the counter. The
Rate Indicator will not add appreciable sensor load with this arrangement.
Note: Rate Indicator cannot be operated in parallel with standard input
counters when 2-wire proximity sensors are used.
10.
INPUT AND POWER CONNECTIONS:
There is a plug-in,
compression-type, terminal block located at the rear of the unit. This block
can be removed from the rear of the unit for ease of wiring. After wiring is
complete, the connector can be plugged back onto the unit.

INPUT SET-UP
The selection of input set-up is accomplished by the first three of six DIP
switches, located along the side of the unit. DIP switches 1-3 are used to
configure the input. Each of these switches are discussed below.
Note: Rate indicators frequently use magnetic pickups for input devices, while
contact input is never used due to speed and contact bounce limitations.
Consequently, there are basic differences between counter and rate-indicator
input circuits. In the Model APLR/PBLR input circuit, the hysteresis level is
quite small and the bias levels are significantly different to accommodate
both magnetic pickup inputs, as well as the +5 V and higher logic levels.
S1 - ON [MAG.PKUP.]
: Connects a 0.1 µf damping input capacitor from input
to common. This capacitor is used only with magnetic pickup inputs and
serves to filter out high frequency noise. S1 should be set in the “OFF”
position when using inputs other than magnetic pickups.
S2 - ON [LOGIC]
: Sets the bias reference so that input logic signals trigger
count pulses as they cross a level of approxi2.5 V.
OFF
: Sets the bias reference so that a signal of 150 mV or more will trigger
count pulses. This provides the sensitivity required for low speed
magnetic pickup sensors.
Note: Hysteresis for both S2 “ON” and “OFF” conditions is about 25 mV.
This means the difference between V
IL
and V
IH
with logic inputs (S2) is
almost insignificant and only a very small swing about the 2.5 V bias
level will trigger the input.
S3 - ON [NPN O.C.]
: Connects a 3.9 K pull-up load resistor for sensors or
circuits with current sink output. Sensor output must sink 4 mA @ V
OL
of 1 V or less.
DECIMAL POINT SELECTION
The selection of Decimal Point is accomplished
by DIP switches 4 and 5. The table at the right
shows what combination of switches is needed to
obtain the desired decimal point location. The unit
always has leading zero blanking. Note: D.P. will
change only at the normal display update time of
the unit.
REAR PANEL DIP SWITCHES
As can be seen from the rear of the unit, there is a row of 14 DIP switches
located beside the input and power terminal block. DIP switches 1 through 13
are Time Base Increments. When the switch is “ON”, it will add time to the
Time Base Increment total.
DIP switch 14 is the Frequency Doubling DIP switch. When it is “ON”, twice
the number of input pulses are registered in the unit. Doubling the input rate
allows the Time Base Increment total to be halved, thus allowing faster update
times with the same value displayed.
SELF-TEST
This unit has a built-in self-test feature which can only be activated
immediately after power-up (the unit will not count while in self-test). To
activate self-test, set the self-test DIP switch (D.S. 6) to the enable position.
Then power the unit up. With this test, all digits are cycled through starting with
a string of six zeros. This will be shown for about half a second, then a string of
ones will appear for about the same time duration. Following these, a string of
twos and so on, up to nines will be displayed. After the nines are shown, a string
of decimal points will appear. Next an interlace pattern of 1, 0, 1, 0, 1, 0, then
1, 2, 1, 2, 1, 2, and so on, until all digits from zero to nine have been displayed.
