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.

R
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.

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)
