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 A103-000 meets the requirements for basic count totalization applications.
No required programming leads to plug-and-play simiplicity and minimal installation time.
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.
A NEMA 4X rating and a high
level of noise immunity make this
unit sutiable for harsh
environments. Several option
modules are also available that
provide added functionality and
convenience.

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 (0). 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.
