Relay or Analog Output, Lag Control Mode

Overview

The Lead Lag control mode allows a group of outputs to be controlled by a single control algorithm using a variety 

of configurations. The control mode support backup pumps operation, alternate pump with wear leveling, and the 

activation of additional outputs after a time delay, or based on alternate set points, or based on digital state changes.
A Lead Lag group consists of a single Lead output and one or more Lag outputs. The Lead output can be set to any 

control mode. The new Lag control mode can be selected for any number of additional outputs (limited only by the 

number of outputs available within the controller). A setting for each Lag output allows selection of a Lead output 

that is used to create an ordered group of Lead Lag relays.

Example: R1 is an On/Off relay, R2 is set for Lag mode with a Lead output of R1. R3 is set as an additional 

Lag mode relay with a Lead output of R2, thus creating an ordered chain of three relays in the Lead Lag group 

(R1←R2←R3). After the group is defined, the Lead output (R1) operates with the standard On/Off Control func

-

tionality. The last Lag mode relay in the chain (R3) offers various settings that are used to define the desired control 

operations for the entire Lead Lag group. Selectable Lead Lag control options include backup, wear leveling, and/

or activating additional outputs based on various criteria.

Backup Pump Control

By default, Lead Lag groups always provide backup operation if the Lead control mode determines that its output 

should be energized but it is disabled due to a Flow Verify alarm and/or because the Lead output HOA setting is 

Off or Hand (not in Auto mode).

Wear Leveling Modes

The order of Lead and Lag output activation can be changed based on configurable wear leveling modes. This 

option is intended to allow users to manage the usage of primary and secondary pumps within a system. One wear 

leveling mode selects a different output each time the group is activated. Additional modes vary the activation of 

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:

On-time (for example, energize a second relay 10 minutes after the primary relay is turned on)

Control set points (for example, energize a second relay if the pH continues to rise)

Switch change (for example, energize a second pump to maintain a tank level when the low-low level switch opens

Control Operation

Backup Pump Control

The default control operation for the Lead Lag group is that if a condition exists that prevents one relay from being 

activated, it is skipped and the next output in the group is turned on instead. This situation may occur if the output 

is experiencing an active Flow Verify alarm or the output is not in Auto mode. Backup control using a Lag output 

does not require any additional settings and could be used to create an output for a backup pump to be activated 

only if the main pump loses prime and/or is taken out of service for maintenance.

Example: A Lead Lag group consisting of R1, R2 & R3 is configured (R1←R2←R3). All three pumps have Posi

-

Flow monitors wired to inputs D1, D2 & D3, respectively. R1 uses On/Off mode to control caustic feed to maintain 

a pH set point above 7.0. R1 and R3 pumps are in Auto mode, R2 pump has been taken out of service for mainte

-

nance and is currently in HOA Off mode. The process pH falls below 7.0 and R1 is energized. Before the pH rises 

to satisfy the dead band, the D1 PosiFlow input monitors an error condition and activates a Flow Verify alarm for 

the R1 pump. The Lead Lag system de-energizes R1 and checks the status of R2. Because R2 is not is service, R3 is 

energized to maintain caustic feed.
