CKW Relay Option Kit
INTRODUCTION
Two optional Relay Kits are available for CKW Series Indicators and Scales. The
AC Relay Kit is used for controlling up to three external AC circuits. The DC Relay
Kit is used for controlling up to three external DC circuits. Each solid-state relay
output is equivalent to a single pole, single throw switch (SPST). Each relay
circuit is protected by a replaceable fuse.
When installed, system software allows the relays to be programmed in a variety
of ways. Optional set ups include: Normally open or normally closed simulation,
on-off or on-hold sequencing, simultaneous, break-before-make (BBM) or make-
before-break (MBB) contact switching.
Each kit contains a PC board, 2 cables, 6 mounting screws, metal cover, cable tie
and this instruction manual.
BASIC APPLICATIONS
With the Relay Option board installed, external devices can be coordinated to
work with the system's bar graph display.
• Relay Out 0 corresponds to the Yellow Under Bar graph section.
• Relay Out 1 corresponds to the Green Accept Bar graph section.
• Relay Out 2 corresponds to the Red Over Bar graph section.
Applications include: driving external Over/Accept/Under displays, motor controls
for semi-automatic filling systems, sorting systems, interfacing to industrial PLC
systems, etc. The Relay outputs can also be used as slave relays to drive higher
power relays in larger systems.
CAUTION: Read all safety warnings before installing, making
connections, or servicing the Relay option PCB. Failure to comply
with these warnings could result in personal injury and/or property
damage. Retain all instructions for future reference.
