Setpoint Ramp Rate

The rate at which the actual setpoint value will move towards its target value, when the setpoint value is adjusted or the active setpoint is changed. With ramping in use, the initial value of the actual setpoint at power up, or when switching back to automatic mode from manual control, will be equal to the current process variable value. The actual setpoint will rise/fall at the ramp rate set, until it reaches the target setpoint value. Setpoint ramping is used to protect the process from sudden changes in the setpoint, which would result in a rapid rise in the process variable.

Settings = 1 to 9999 LSDs per hour.

Default Value = OFF

Also refer to: Active Setpoint, Actual Setpoint, LSD, Manual Mode, Process Variable, Setpoint, Setpoint Ramp Editing and Setpoint Selection.

Setpoint Selection

There can be either one or two setpoints. These can be Local Setpoint 1 or an Alternative Setpoint chosen from either Local Setpoint 2 or a remote setpoint input from Auxiliary Input A or B if these are fitted. The Setpoint Select parameter in the control sub-menu defines whether the Active Setpoint will be the Local Setpoint 1 only, the Alternative Setpoint only or if the choice of active setpoint will be made from a digital input or an Operation Mode selection screen.

Also refer to: Active Setpoint, Alternative Setpoint, Auxiliary Input, Digital Input, Local Setpoints, Remote Setpoint, Setpoint.

Setup Wizard

A sub-set of the Configuration Menu parameters chosen to allow inexperienced users to easily set the instrument up for most simple applications. The parameters shown depend on the options installed.

The Setup Wizard runs automatically at first ever power-up or whenever a Reset To Defaults is carried out. A partial Wizard also runs whenever option modules have been changed. The partial wizard only shows parameters affected by the changes made. The full Setup Wizard can also be run manually from the Main Menu (this requires entry of an un-lock code).

Once completed, the Setup Wizard exits to Operation Mode.

Experts or users with more complex applications should select the parameters they wish to set-up from the Configuration Menus instead of using the Wizard.

Refer to the Setup Wizard information in the Configuration & Use section.

Also refer to: Lock Codes, Configuration Menu, Main Menu, Operation Mode and Reset To Defaults.

Solid State Relay (SSR)

An external device manufactured using two Silicone Controlled Rectifiers in reverse parallel. They can be used to replace mechanical relays in most AC power applications. Some special SSRs can switch DC, but most cannot. As a solid-state device, an SSR does not suffer from contact degradation when switching electrical current. Much faster switching cycle times are also possible, leading to superior control. The instrument’s SSR Driver output provides a time-proportioned 10VDC pulse for to the SSRs signal input terminals. This causes conduction of current from the line supply through the SSR to the load, when the pulse is on.

Also refer to: Cycle Time, Time Proportioning Control, Relay, and Triac.
