The 16 pin terminal strip includes four dispense valve initiate inputs, an alarm
I/O, an End of Cycle output, and a 24VDC courtesy power output.
The four initiate inputs can be connected in series, parallel, or to separate input
sources for independent valve control, or ability to disable a specific valve when
using “part in place” verification.
For a detailed connection schematic and instructions, refer to page17.
The alarm I/O is used to monitor air supply pressure and / or tank low level. This
I/O can be used to operate an audible alarm, or be connected to the machine
controls to shut off the machine if air pressure or tank level is low. In addition,
when the alarm is activated, the display will flash “ALr”
, indicating that air
pressure or tank level has dropped below minimum.
The End Of Cycle (EOC) feedback can send a signal back to the machine
controls, signaling when the dispense cycle is finished. Using this signal can
increase machine productivity by eliminating any delay after the dispense cycle
and also confirms a dispense cycle has occurred. 2 INIT and 4 INIT are non-
active inputs. As long as an initiate sequence is in progress on any channel, the
EOC circuit is open. Maximum load is 100 mA from 5 to 24 VDC.
