Page 7 An option card with two isolated analog outputs may be installed to retransmit sensor input signals to a chart recorder, datalogger, PLC or another device. They may also be connected to valves, actuators or metering pumps for linear propor- tional control, flow proportional or PID control. An Ethernet option provides remote access to the controller’s programming via a PC connected directly, via a local area network, or via the Fluent account management server.

Page 70 Special Condition Handling Prebleed If both a time limit and a conductivity limit are set, the time limit takes precedence. The bleed relay will turn off once the time limit is reached or when the prebleed conductivity limit is reached (whichever occurs first). If the prebleed has a conductivity limit set, then the time limit can’t be set to zero, as this would allow the prebleed to last forever if the conductivity limit is never reached.

ONLY AVAILABLE IF CONTROLLER INCLUDES PULSE OUTPUT HARDWARE Output Details The details for this type of output include the relay pulse rate, HOA mode or Interlock status, accumulated on-time, alarms related to this output, current cycle on time, relay type and the current control mode setting.
Page 74 PID Equation Formats The controller supports two different forms of the PID equation as specified by the Gain Form setting. The two forms require different units for entry of the PID tuning parameters. Standard The standard form is more commonly used in industry because its time-based settings for the integral and deriva- tive coefficients are more meaningful.

Page 82: Relay, Dual Switch Control Mode
5.3.21 Relay, Dual Switch Control Mode Dual Switch mode is typically used to fill or empty a tank, using a level switch contact closure to activate the relay when the liquid level is at one extreme and deactivate the relay at the other extreme. It is more versatile than that; the on and off triggers may be any digital input or relay output state.
Page 83 the pumps within the group based on the time-on for each output, with the intent to either balance the usage of each pump or to energize the primary output most often and periodically exercise auxiliary pumps to insure proper operation when they are needed. Output Activation Modes Depending on the control mode selected for the Lead output, Lag output(s) can be configured for activation of additional outputs based on one or more of the following criteria:...
Page 84 after its deadband is satisfied. The next time the measurement goes below the setpoint, R2 is activated and R1 remains off. After all outputs in the group have been exercised for one feed cycle, the process begins again with the first output (R1).
Page 85 In On/Off, Dual Setpoint, or Spike control modes, additional pump(s) are energized if the process value remains outside the setpoint range for more than the specified delay time. Example: In a two-output Lead Lag group (R1←R2), the Lead (R1) output, set for Dual Setpoint control, is pro- grammed to energize its output when the D.O.
Page 86 another 1 hour, the R3 pump is activated. When D2 opens, R3 is turned off. When D1 opens, both R2 and R1 are turned off. In this configuration, the R3 pump serves not only as a backup in case one of the pumps is down for maintenance, but also provides additional capacity should it be needed.

Select the control direction. 5.3.25 Analog or Relay Output, PID Control Mode ONLY AVAILABLE IF CONTROLLER INCLUDES PULSE OUTPUT OR ANALOG OUTPUT HARDWARE & HVAC MODE IS DISABLED The PID algorithm controls an analog output using standard Proportional-Integral-Derivative control logic. The algorithm provides feedback control based on an error value continuously calculated as the difference between a measured process variable and a desired set point.

In all cases, larger gain values result in faster output response.
Page 91 and the process value will continue to rise. To optimize system recovery after wind-up situations, the controller suppresses updates to the Current Integral that would drive the output beyond its minimum or maximum limit. Ideally, the PID parameters will be tuned and the control elements (pump, valves, etc.) will be sized properly so that the output never reaches its minimum or maximum limit during normal control operations.

SSL Certificate Only appears if Webserver Mode is HTTPS. Select between Default Cert (which uses a self-signed certificate) or Upload PEM which provides a way to enter a certificate of the network IT administrator’s choice. DNS Name Only appears if Webserver Mode is HTTPS and Default Cert is selected. The network IT administrator can map the controller numeric IP to a domain name, which reduces the warning messages that occur when a self-signed certificate is detect- ed by the browser.
