OVERVIEW
The 9100 is a versatile multi-function counter/ratemeter and
process controller. Features include:-
• LCD three-row dot matrix display with backlight;
• simultaneous display of instantaneous, batch and total
counts;
• seven count modes;
BASIC OPERATION
Inputs A and B receive count pulses. The 9100 counts
these and also measures the rate at which the pulses are
arriving on input A only (input B in quadrature x 1 mode).
The progress of the count or the rate is shown on the front
panel display according to the mode and the scale values
you program into the unit.
Outputs R1, R2 and R3 change state when the count or the
rate becomes equal to a preset value (P1, P2 or P3) which
you set for each output. Each of the three outputs can be
programmed to respond either to a count value or a rate
value, as required. Each output can be independently
programmed to remain in the changed state for an amount
of time which you can set (the ‘on time’) - this is called
Pulsed Mode - or to remain in the changed state until the
end of a complete count cycle - this is called Latched Mode.
The normal sequence for outputs, in count mode, is for P1
and P2 to be set between zero and P3, since the value of
P3 determines the end of a cycle of counting; outputs 1 and
2 will therefore change state at preset points within the
count cycle. If you have chosen ‘automatic reset’ mode,
then reaching the end of a count cycle resets all latched
outputs to their initial state. If you have chosen ‘manual
reset’ mode, then latched outputs remain latched until the
counter is reset from the front panel or by a pulse on the
External Reset input.
Output 1 can alternatively be set up as a batch counter,
which you can preset to operate when a certain number of
count cycles have been completed.
Output 2 can alternatively be set up as a ‘motion monitor’.
In this mode, if no count pulse has been received for 12.8
seconds (equivalent to 4.7 rpm when using a shaft
encoder), then relay R2 operates to provide an indication
that the process has stopped. When the next pulse is
received, R2 releases and timing starts again.
• comprehensive prescaling for direct display in units of
your choice;
• three fully programmable relay outputs for process
control;
• simple, straightforward visual programming;
• programming in any of four European languages.
COUNT TYPES
UNI + DIR
Count is incremented or decremented by input A. Direction
is determined by input B:-
Input B open - Increment
Input B closed - Decrement
A+B
Count is incremented by either input A or input B.
A-B
Count is incremented by input A and decremented by B.
A/B
Count is incremented by input A. Display is derived from
input A divided by input B. Manual reset (keyboard or
remote) is required to clear the B count value.
Quadrature Counting Modes
For all quadrature modes, the phase of input A must lag or
lead that of input B by 90 degrees.
For an incrementing count, A must lead B by 90 degrees.
For a decrementing count, A must lag B by 90 degrees.
Quadrature x1
Count is incremented or decremented on the rising edge of
input B.
Quadrature x2
Count is incremented or decremented on the rising and
falling edges of input A.
Quadrature x4
Count is incremented or decremented on the rising and
falling edges of both inputs.
Note: In the quadrature counting modes, use electronic
sensors because inputs A and B are not debounced.
EXTERNAL CONNECTIONS
Two terminal blocks are provided at the back of the counter,
arranged as shown. The terminal strips may be unplugged
from the counter to facilitate easy wiring.
