FUNCTION #
30:
FAIL SAFE TIMEOUT
The pulse signal from the transmitter will be interrupted
if the transmitter, the meter, the pump or other component
fails. Enter 0 to turn off Fail Safe Timeout.
This function allows you to program a period of time from
1 to 99 seconds since the last pulse received. If a pulse is not
received in this period, the outputs are de-energized and the
operation is stopped. There is also a fixed fail safe for
starting operation. If no pulse is received in a 5 second period
following the start command, the operation is stopped.
Six zeros will flash to alert the operator of the failure. If
a printer is connected, the message “B count NO CNT” will
be printed.
To return the unit to normal operation after the problem
has been solved, you must press the STOP key first.
FUNCTION #
53
: DECIMAL POINT POSITION
This function must be programmed if the scale factor was
set up for fractions of a gallon, liter, etc. To program, simply
enter the number of decimal points required on the display.
Example: If measuring in tenths of a gallon, then enter
1. If measuring in hundredths, then enter 2, and so on. The
display will show 0.1, 0.02 and 0.003 respectively. The pro-
grammed decimal point will also appear in the totalizer and
rate of flow indications.
FUNCTION #
33
: TRANSISTOR OUTPUT MODE
Program this function only if you plan to use the transis-
tor output on terminal #7 for one of these three available
options.
0
-
Totalizer Output.
This is a transistor scaled pulse
output. It is usually used to connect to remote total-
izers or process controllers. The pulse width can be
programmed with function #36.
1
-
End of Batch Output.
This is a transistor output with
a variable pulse width that is activated at the end of
each batch. If connected to a remote counter, it can
be used to totalize the number of batches run for a
period of time (day, week, year or shift). If connected
to terminal #17, a second PC100, it can be used to start
The display will show...
Once all wiring has been completed, the unit can be
programmed for your application. Those functions marked
“MUST” have to be programmed if the PC100 is being used
as a batch controller.
FUNCTION #
50
: COUNT DIRECTION
This function allows you to program the way your trans-
mitter input(s) will be counted in the display. Your choices
are as follows:
0
- Input on terminal #10 will count up,
input on terminal #14 will count down.
1
- Input on either terminal will count up.
2
- Input on either terminal will count down.
3
- Inputs on both terminals will count up in
quadrature.
4
- Inputs on both terminals will count up in
double quadrature.
Unless you are using quadrature transmitters, we recom-
mend always using either code 1 to count up, or code 2 to
count down in order to be able to use either input.
FUNCTION #
51
: RESET OR PRESET
After the count direction has been determined and
programmed, you have to decide what the counter should
show at the end of the batch. Your choices are as follows:
0
- If counting down, counter will stay at zero.
1
- If counting down, counter will go back to preset
value.
2
- If counting up, counter will stay at batch preset.
3
- If counting up, counter will go back to zero.
Example: You may decide to count from the preset down
to zero and at the end of the batch stay at zero so that you
know that the batch was run. On the other hand, you may
want the counter to reset to your batch value so that you may
know what the batch was set at before starting a new batch.
Programming this function is important because once
you press START the counter will immediately reset to zero
on count up, or to batch size on count down, and start the
operation. If you set the counter to stay at zero but would like
to know what your batch is before the next operation, just
press the 1 key and then the ENTER key.
