TERMINAL ASSIGNMENTS AND FUNCTIONS

 #1 - BYPASS PRESET 1 INPUT

Connecting this terminal to DC Common causes
the counter to ignore Preset 1. When the counter
reaches Preset 1, Transistor Output 1 remains off
and any other functions (such as auto recycle at
Output 1) will not occur.

NOTE:

In the sequential mode, this input must be
energized before the counter starts count-
ing to or from preset 1 for bypass to occur.

#2 AND 3 - TRANSISTOR OUTPUT UNLATCH 
INPUTS

These two terminals are programmable inputs
which may be used to unlatch any two of the three
transistor outputs. Function code 49 is used to
select which output is unlatched by each input
(see Figure 21). When an Unlatch input is ener-
gized, the selected output turns off. If the output is
already off, the Unlatch input has no effect. If the
output has been reversed the Unlatch input turns
the output on.

#4 - BYPASS PRESET 2 INPUT

This input operates the same as #1 above except
it applies to Preset 2 and Transistor Output 2.

#5 AND 8 - TRANSISTOR OUTPUT 1

These outputs are open collector NPN transistors
with built-in transient overvoltage protection in the
form of zener diode clamping. Each transistor is
rated at 30 Vdc maximum and can sink up to 300
milliamps. Both transistors turn on as shown in
Figure 3 for Output 1.

#6 AND 9 - TRANSISTOR OUTPUT 2

These outputs have the same configuration as #5
and 8 above except that they turn on as shown in
Figure 3 for Output 2.

#8, 9, 12 AND 21 - DC COMMON

These terminals are internally connected to the
negative side of the DC power supply.

#10 AND 14 - COUNT INPUTS

These two count inputs are used to increment or
decrement the counter. Terminal #14 is labeled
“COUNT INPUT 1” and terminal #10 is “COUNT
INPUT 2.” The table shown in Figure 7 lists the
operation of the two count inputs as related to the
count function, and indicates how each input
causes the counter to operate when a DC Com-
mon signal is applied.

#11 AND 13 - LOW FREQUENCY SELECT 
INPUTS

When contact closures are used for count
sources, it must be remembered that the contacts
will bounce slightly each time they close. This
slight bounce can cause extra counts to be
entered into the counter. This effect can be elimi-
nated by limiting the allowable frequency response
at the count inputs. The low frequency select ter-
minals reduce the count input frequency response
from 7500 PPS to 150 PPS when they are con-
nected to DC Common. Terminal #13 is LOW
FREQUENCY SELECT for COUNT INPUT 1 (ter-
minal #14) and terminal #11 is LOW FREQUENCY
SELECT for COUNT INPUT 2 (terminal #10). Low
frequency is selected by placing a jumper between
terminal #11 and/or terminal #13 and DC Com-
mon. Use the Low Frequency inputs whenever
possible to guard against electrical noise and
interference.

#15 - PROGRAM INHIBIT INPUT

The PROGRAM INHIBIT terminal, when con-
nected to DC Common through the use of a
jumper, prevents all of the programming functions
from being changed. Modification of the Preset
values can also be prevented with this jumper if
Function Code 41, Preset Lock, is set to a value
other than “0.”
