MAXIMUM COUNT RATES
:
High Frequency
: For the single preset unit only - 15 KHz max. square wave
input for all electronic sensors, under all modes of operation. For dual
preset units, the following chart lists the count rates for all the possible
prescale values.

Note: For prescale values greater than 7, the timed delay output is affected
by the count speed (rate).
Low Frequency
: both single and dual preset units - 100 Hz for switch
contact closures.
Note: These units will operate with VCM (E through H)
modules.

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 Control:
Response time = 150 µsec. A low will cause the unit to
count down. A high will cause the unit to count up.

Relay
: Form C contacts max. rating 5 amps @ 120/240 VAC, 28 VDC
(resistive load), 1/8 H.P. @ 120 VAC (inductive load). The operate time is
5 msec. nominal and the release time is 3 msec. nominal.
Relay Life Expectancy
- 100,000 cycles at max. rating.
(As load level
decreases, life expectancy increases.)
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.

: -40 to 70°C
Operating and Storage Humidity
: 85% max. relative humidity

FRONT PANEL FUNCTION DESCRIPTION
The units employ eight front panel buttons for control and data entry. The
button functions are as described below:
RESET “R”:
Resets the counter to either zero or preset, depending on the
mode of operation selected. For this button to operate, the enable/disable
reset switch at the rear of the unit must be set to the enable (EN.) position.
The reset button is also used in conjunction with the preset button(s), to view
and change the timed output value(s). When reset is activated, all processes
are stopped or interrupted (i.e. outputs turn off, display is reset, etc.). This is
the case under any mode of operation, in any data entry mode.
PRESET “P1” (“P2”):
Labeled P1 and P2 (single preset units only have the
P1 preset button).
The preset 1 value is displayed when the P1 button is pressed, and the Preset
Value mode is accessed (See Program Preset Value). The value remains
displayed for approximately 10 seconds after the button is released. The
preset buttons are also used, in conjunction with the reset button, to view and
change the timed output values (See Program Timed Output Value section.)
ENTER “E”:
Used when programming the Preset Value or the Timed Output
Value. After the desired value is obtained on the display, pressing the E
