Important: As of Release 5.0, the Tower Sequencing-3 Speed v50 module replaces the Tower Sequencing-3 Speed module.

The Tower Sequencing-3 Speed module is responsible for sequencing cooling tower fans to maintain a setpoint. This module accepts as inputs a mode, a process variable, a setpoint, a minimum on time, a minimum off time, a rotate now, process units, a device x runtime (where x is 1-4), and a device x enable (where x is 1-4). Based on the input commands and the attribute settings, the module outputs a control status and a device x out (where x is 1-12). The module resets the PIDs to default tuning parameters if the Reset PID Tuning input is not Normal.

You can view and modify the modules in this group’s logic.
