Introduction
Within the Danaher Controls A103 family you'll find a product to meet nearly every
requirement for panel mounted control and indication. Housed in a DIN standard 36mm x
72mm case, the A103-001 is an ideal choice for advanced count totalization applications.
An input scale factor allows input pulses to be displayed as meaningful engineering units,
and dual input channels enable add/subtract counting.
The 8 digit supertwist LCD display provides easy viewing at a glance. For conditions where
ambient light is poor, the display can be backlit by connecting an external DC (10-28 Volt)
power supply. A single unit can accept NPN & dry contact inputs for low speed (30Hz)
counting and PNP or square wave signals for high speed applications up to 10 kHz.
Powered by either one or two replaceable 3V Lithium batteries, this unique design allows for
a new battery to be installed before removing the old one, thereby retaining count total and
program data. A low battery indicator appears on the screen to provide a warning several
weeks before the end of battery life. If two batteries are used simultaneously, the individual
expected life doubles to 10 years.
Setup is quick and simple as the
two front panel keys are used to
scroll through 4 menu choices. A
NEMA 4X front panel and noise
immunity tested to IEC 801 level 3
makes this unit suitable for harsh
environments.

1. Total Display
2. Down Key
1. Total Display: Indicates the present count value, which is equal to
the number of pulses received (since the last reset) multiplied by the
Count Input Calibrator in Program mode.
2. Down Key: When the program input is active this key is used to
scroll through the menu items. After a menu item has been chosen for
editing, the down key is used to set the value for the currently selected
(flashing) digit.

3. Next/Reset Key
3. Next/Reset Key: If the total value is being displayed depressing
this key will cause the value to be reset to 0. When the program input
is active this key is used to select a menu item for editing (left most
digit will begin to flash) and then move to the desired digit to be
changed.

Battery Slots
Battery Installation - The unit is shipped with one battery, which is not
installed. Remove the battery cover by pushing inward and down. Install
the battery in either of the two slots. The unit runs on a single battery,
and the second slot is provided to allow for installing a new battery before
removing the old one, retaining count total and program data. The unit
can also be run on two batteries to extend the battery life to 10 years.
Once the battery is in place the unit will go into a self test mode, and all
the segments on the LCD display will be illuminated. The self test mode
is exited by depressing the Next key, which will then display the model
number (1). Depress the Next key again to ready the unit for operation.
Front Panel Installation - Place the unit in the panel through the
33mm x 68mm cutout. Slide the included gasket over the rear of the
unit, then slide the panel mount bracket into place so that the 4 tabs
catch in the groves on the top and the bottom of the unit (the bracket
should be oriented so that the tabs are on the side nearest the panel).
Used the provided panel mount screws to tighten the bracket until
there is a secure seal against the gasket.

Programming parameters can be accessed, when the Program Enable input is active, by
pressing the Down key. To edit a parameter use the Down key to scroll until the desired
parameter appears on the screen. Pressing the Next key will cause the leftmost digit of
that value to begin to flash. Use the Next and Down keys in combination to choose
individual digits and change their value.
Count Input Calibrator: Multiplies the input pulses by a value settable from 0.0001 to 99.9999, and
displays the results as the count value.
Display Decimal Point: Sets the decimal point on the count display from Off to 0.00000. The Next key
is used to scroll through the choices.
Count Offset - Enables the counter to be reset to a value other than 0. Settable in a range from
-999999 to 999999.
Front Panel Reset Enable: When active (ON) the count value, when being displayed, can be reset by
pressing the Next/Reset key. If set to OFF, the total value can only be reset through the remote input..
