Veeder Root A103-007 Preset Counter Technical Manual

Introduction

Veeder-Root

brand

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 A103-007 is an ideal choice for event counting operations which require a
preset. An intenal solid state relay provides a logic signal that can be sent to antother
control device or to an external relay.

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.
Several option modules are available,
inclunding a 5 amp relay which would
enalbe the unit to directly drive a
load.

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

2. Down Key: Toggles the unit between the total and preset displays
when in Operation Mode. 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.

REAR TERMINAL CONNECTIONS

3. Next/Reset Key

3. Next/Reset Key: When in Operation Mode, depressing the key will

reset the count value to 0, if Front Panel Reset has been enabled in
Programming Mode. 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.

4. Preset Value: Indicates the number at which the output will be
activated (for Up counting) or the reset value (for Down counting)

Battery Slots

Battery Installation - The unit is shipped with two battery, which are not

installed. Remove the battery cover by pushing inward and down. Install
the batteries in the two slots. The two batteries are capable of sustaining
the output for 6 months at 50% duty cycle (To extend the battery life to 5
years utilize an external DC supply or the AC option module for powering
the output). 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 (7). 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).
Use 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 Direction: Determines if the count value will increment from zero and change the state of the
output at the preset (Up), or decrement from the Preset and change the state of the output at zero
(Down).

Preset Lock: When enabled the preset value can not be changed through the front panel.

Output Mode - Determines whether the output will activate prior to reaching the preset (or zero for

down counting) and then release when that value is achieved (Interval), or will be Off prior to reaching
the preset (or zero for down counting) and then activate when that value is achieved (On-Delay).

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.

Output Enable: When active (on), the SSR output will activate as described above in Output Mode.
If set to off, the output will not activate. (Use the "off" setting to conserve battery life if not using the output)
