Solid-State Switch and Form C Output Wiring

The Series 3000 flow monitor has one Normally Open (N .O .) solid-state switch, and one solid-state form "C" relay . See
"Specifications" on page 24
These outputs are completely independent, electrically isolated, and can be programmed as either Pulse or Set Point outputs .
When the "Totalizer" function is selected, the unit of measure and resolution are independent from the displayed units and
can be programmed where one pulse occurs once every 0000000 .1 to 999999999 . of units selected, with any pulse width
from 0001 to 9999 mS .
When the "Alarm" is selected as the unit of measure and the resolution is independent from the displayed units, it allows the
unit to be programmed as either a high or low rate Set Point . Since the Set Point, Release Point and their associated time
delays are fully independent, this output can be either a classical high rate or low rate alarm, depending on the settings
selected . When design planning, keep in mind that although both of these outputs can be programmed as alarm points only,
the relay provides both N .O . and N .C . contacts . The switch is a simple N .O . contact .
Examples:
High Flow Set Point
The Set Point must be a value greater than the Release Point.
The relay output will have continuity between its N .C . terminal and "COM" until the flow has exceeded the Set Point ("SETPT")
for a continuous period of time exceeding the Set Point Delay ("SDLY"), at which time the N .C . connection will open and
the N .O . contact will have continuity to the "COM" terminal . When the flow has dropped below the Release Point ("RELP")
for a continuous period of time exceeding the Release Point Delay ("RDLY"), the relay states will return to their original
states . If the latch has been set to "ON", the relay will not release until manually reset once the Set Point and Set Delay have
been satisfied .
Low Flow Set Point
The Set Point must be a value less than the Release Point .
The relay output will have continuity between its N .C . terminal and "COM" until the flow has dropped below the Set Point
("SETPT") for a continuous period of time exceeding the Set Point Delay("SDLY"), at which time the N .C . connection will
open and the N .O . contact will have continuity to the "COM" terminal . When the flow has again risen above the Release Point
("RELP") for a continuous period of time exceeding the Release Point Delay ("RDLY"), the relay states will return to their
original states . If the latch has been set to "ON", the relay will not release until manually reset once the Set Point and Set Delay
have been satisfied .
