Solid-State Switch and Form C Output Wiring

The Series 3050 BTU flow monitor has one Normally Open (N .O .) solid-state switch, and one solid-state Form C relay .
See the "Specifications" on page 30
completely independent, electrically isolated, and can be programmed as either Pulse or Setpoint 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...999999999 .0 of units selected, with any pulse width from
0001...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 Setpoint . Since the Setpoint, 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 .
Example of High Flow Setpoint Control
The Setpoint 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 Setpoint (SETPT) for
a continuous period of time exceeding the Setpoint 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 Setpoint and Setpoint Delay have been satisfied . Sources for
the Setpoint control can be Flow Rate, Energy Rate, T1, T2 or Delta T .
Example of Low Flow Setpoint Control
The Setpoint 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 drops below the Setpoint (SETPT)
for a continuous period of time exceeding the Setpoint 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 Setpoint and Setpoint Delay have been
satisfied . Sources for the Setpoint control can be Flow Rate, Energy Rate, T1, T2 or Delta T .
