5.
MAXIMUM COUNT RATES:
High Frequency
: The following chart lists the count rates for all the possible
prescale values.
(maximum square wave input for all electronic sensors,
under all modes of operation.)

Note: For prescale values greater than 7, the timed delay output is affected
by the count speed (rate).
Low Frequency
: 50 Hz max. for switch contact closures. Note: These units
will operate with VCM (E through H) modules.
6.
CONTROL INPUTS:
Active low (V
IL
= 0.5 V max.), internally pulled up
to 5 VDC through a 10 K
Ω
resistor (I
SNK
= 0.5 mA).
Remote Reset
: Response time = 10 msec. A low will reset the unit and
deactivate outputs.
Program Disable
: A low will inhibit the changing of presets, prescale, and
timed outputs, as well as testing outputs in self-test.
Up/Down Contro
l: Response time = 150 µsec. A low will cause the unit to
count down. A high will cause the unit to count up.
7.
OUTPUTS:
Solid-State
: Current sinking NPN Open Collector Transistors.
I
SNK
= 100 mA max., V
OH
= 30 VDC max., V
OL
= 1 V @ 100 mA.
One solid-state output for each preset level.
Programmable Timed Output
: The timed output can be programmed from
0.01 sec. to 99.99 sec., ±0.1% + 10 msec. The timed output is set for 0.1
sec. at the factory.

INPUT CONFIGURATION, FRONT PANEL
RESET, & DIP SWITCH SET-UP
The DIP switches are located at the rear of the unit. DIP switch 1 is used to
select high or low frequency. DIP switch 2 is used to enable or disable the front
panel reset button. DIP switch 7 is used to enable or disable prescale changes.
DIP switches 3 to 6 are used to select the mode of operation. Refer to the block
diagram of the unit for the details of count and control circuitry.
SWITCH SET-UP
S1 - HI FRQ.:
Removes damping capacitor and allows operation up to the
maximum frequency (See max count rates in specifications).
LO FRQ.:
Connects damping capacitor for switch contact de-bounce.
Limits count speed to 50 Hz. Minimum count ON/OFF times - 10
msec.
S2 - DIS.RST.:
Disables front panel reset.
EN. RST.:
Enables front panel reset.
S3 to S6:
These are the mode select DIP switches. See Modes of Operation
for the switch settings of a specific mode.
S7 - PRESCALE EN./DIS.:
When S7 is in the DOWN position, prescale
information can be changed. When S7 is in the UP position,
prescale information cannot be changed.
