6.10Monitors Configuration

Overview

Monitor 1, 2, 3, and 4

A Monitor Block is used to determine when a process value is greater or less than a specified setpoint. Monitor blocks can be used for ON/OFF type control or, in conjunction with switch and math blocks to change process gain based upon control regions. The Monitor block provides a hysteresis value limit output transitions near the set point value. The Monitor block can be configured as either a High or Low Monitor type. There are four monitor blocks provided for general use.

Unlike Alarms, Monitor blocks do not create an event in the event history, nor do they cause a status message to appear on the display.

Accessing Monitors Menu

•Press Setup to display the Main menu.

•Use the keys to select “Monitors” then press Enter to enter the sub-menu.
